History of India

Bronze Age (c. 3300 – 1800 BCE)

Indus Valley Civilisation

The Bronze Age in the Indian subcontinent began around 3300 BCE. The Indus Valley region was one of three early cradles of civilisation in the Old World; the Indus Valley civilisation was the most expansive, and at its peak, may have had a population as high as five million.

The civilisation was primarily centred in modern-day Pakistan, in the Indus river basin, and secondarily in the Ghaggar-Hakra River basin. The mature Indus civilisation flourished from about 2600 to 1900 BCE, marking the beginning of urban civilisation on the Indian subcontinent. It included cities such as Harappa, Ganweriwal, and Mohenjo-daro in modern-day Pakistan, and Dholavira, Kalibangan, Rakhigarhi, and Lothal in modern-day India.

Inhabitants of the ancient Indus River valley, the Harappans, developed new techniques in metallurgy and handicraft, and produced copper, bronze, lead, and tin. The civilisation is noted for its cities built of brick, and its roadside drainage systems, and is thought to have had some kind of municipal organisation. The civilisation also developed an Indus script, the earliest of the ancient Indian scripts, which is presently undeciphered. This is the reason why Harappan language is not directly attested, and its affiliation is uncertain.

After the collapse of Indus Valley civilisation, the inhabitants migrated from the river valleys of Indus and Ghaggar-Hakra, towards the Himalayan foothills of Ganga-Yamuna basin.

Ochre Coloured Pottery culture

During the 2nd millennium BCE, Ochre Coloured Pottery culture was in Ganga Yamuna Doab region. These were rural settlements with agriculture and hunting. They were using copper tools such as axes, spears, arrows, and swords, and had domesticated animals.

Iron Age (c. 1800 – 200 BCE)

Vedic period (c. 1500 – 600 BCE)

Starting around 1900 BCE, Indo-Aryan tribes moved into the north-west of India from Central Asia in several waves of migration. The Vedic period is when the Vedas were composed of liturgical hymns from the Indo-Aryan people. The Vedic culture was located in part of north-west India, while other parts of India had a distinct cultural identity. Many regions of the Indian subcontinent transitioned from the Chalcolithic to the Iron Age in this period.

The Vedic culture is described in the texts of Vedas, still sacred to Hindus, which were orally composed and transmitted in Vedic Sanskrit. The Vedas are some of the oldest extant texts in India. The Vedic period, lasting from about 1500 to 500 BCE, contributed to the foundations of several cultural aspects of the Indian subcontinent.

Vedic society

Historians have analysed the Vedas to posit a Vedic culture in the Punjab, and the upper Gangetic Plain. The Peepal tree and cow were sanctified by the time of the Atharva Veda. Many of the concepts of Indian philosophy espoused later, like dharma, trace their roots to Vedic antecedents.

Early Vedic society is described in the Rigveda, the oldest Vedic text, believed to have been compiled during the 2nd millennium BCE, in the north-western region of the Indian subcontinent. At this time, Vedic society consisted of predominantly tribal and pastoral groups, distinct from the Harappan urbanisation which had been abandoned. The early Indo-Aryan presence probably corresponds, in part, to the Ochre Coloured Pottery culture in archaeological contexts.

At the end of the Rigvedic period, the Vedic society expanded from the north-western region of the Indian subcontinent into the western Ganges plain. It became increasingly agricultural and was socially organised around the hierarchy of the four varnas, or social classes. During this period, many of the previous small tribal units and chiefdoms began to coalesce into Janapadas (monarchical, state-level polities).

Sanskrit epics

The Sanskrit epics Ramayana and Mahabharata were composed during this period. The Mahabharata remains the longest single poem in the world. Historians formerly postulated an "epic age" as the milieu of these two epic poems, but now recognise that the texts went through multiple stages of development over centuries. The existing texts of these epics are believed to belong to the post-Vedic age, between c. 400 BCE and 400 CE.

Janapadas

The Iron Age in the Indian subcontinent from about 1200 BCE to the 6th century BCE is defined by the rise of Janapadas, which are realms, republics and kingdoms—notably the Iron Age Kingdoms of Kuru, Panchala, Kosala and Videha.

The Kuru kingdom (c. 1200–450 BCE) was the first state-level society of the Vedic period, corresponding to the beginning of the Iron Age in north-western India, around 1200–800 BCE, as well as with the composition of the Atharvaveda. The Kuru state organised the Vedic hymns into collections and developed the srauta ritual to uphold the social order. Two key figures of the Kuru state were king Parikshit and his successor Janamejaya, who transformed this realm into the dominant political, social, and cultural power of northern India. When the Kuru kingdom declined, the centre of Vedic culture shifted to their eastern neighbours, the Panchala kingdom. The archaeological PGW (Painted Grey Ware) culture, which flourished in north-eastern India's Haryana and western Uttar Pradesh regions from about 1100 to 600 BCE, is believed to correspond to the Kuru and Panchala kingdoms.

During the Late Vedic Period, the kingdom of Videha emerged as a new centre of Vedic culture, situated even farther to the East (in what is today Nepal and Bihar state); reaching its prominence under the king Janaka, whose court provided patronage for Brahmin sages and philosophers such as Yajnavalkya, Aruni, and Gārgī Vāchaknavī. The later part of this period corresponds with a consolidation of increasingly large states and kingdoms, called Mahajanapadas, across Northern India.

Second urbanisation (c. 600 – 200 BCE)

The period between 800 and 200 BCE saw the formation of the Śramaṇa movement, from which Jainism and Buddhism originated. The first Upanishads were written during this period. After 500 BCE, the so-called "second urbanisation" started, with new urban settlements arising at the Ganges plain. The foundations for the "second urbanisation" were laid prior to 600 BCE, in the Painted Grey Ware culture of the Ghaggar-Hakra and Upper Ganges Plain; although most PGW sites were small farming villages, "several dozen" PGW sites eventually emerged as relatively large settlements that can be characterised as towns, the largest of which were fortified by ditches or moats and embankments made of piled earth with wooden palisades.

The Central Ganges Plain, where Magadha gained prominence, forming the base of the Maurya Empire, was a distinct cultural area, with new states arising after 500 BCE. It was influenced by the Vedic culture, but differed markedly from the Kuru-Panchala region. It "was the area of the earliest known cultivation of rice in South Asia and by 1800 BCE was the location of an advanced Neolithic population associated with the sites of Chirand and Chechar". In this region, the Śramaṇic movements flourished, and Jainism and Buddhism originated.

Buddhism and Jainism

The time between 800 BCE and 400 BCE witnessed the composition of the earliest Upanishads, which form the theoretical basis of classical Hinduism, and are also known as the Vedanta (conclusion of the Vedas).

The increasing urbanisation of India in the 7th and 6th centuries BCE led to the rise of new ascetic or "Śramaṇa movements" which challenged the orthodoxy of rituals. Mahavira (c. 599–527 BCE), proponent of Jainism, and Gautama Buddha (c. 563–483 BCE), founder of Buddhism, were the most prominent icons of this movement. Śramaṇa gave rise to the concept of the cycle of birth and death, the concept of samsara, and the concept of liberation. Buddha found a Middle Way that ameliorated the extreme asceticism found in the Śramaṇa religions.

Around the same time, Mahavira (the 24th Tirthankara in Jainism) propagated a theology that was to later become Jainism. However, Jain orthodoxy believes the teachings of the Tirthankaras predates all known time and scholars believe Parshvanatha (c. 872 – c. 772 BCE), accorded status as the 23rd Tirthankara, was a historical figure. The Vedas are believed to have documented a few Tirthankaras and an ascetic order similar to the Śramaṇa movement.

Mahajanapadas

The period from c. 600 BCE to c. 300 BCE featured the rise of the Mahajanapadas, sixteen powerful kingdoms and oligarchic republics in a belt stretching from Gandhara in the north-west to Bengal in the eastern part of the Indian subcontinent—including parts of the trans-Vindhyan region. Ancient Buddhist texts, like the Aṅguttara Nikāya, make frequent reference to these sixteen great kingdoms and republics—Anga, Assaka, Avanti, Chedi, Gandhara, Kashi, Kamboja, Kosala, Kuru, Magadha, Malla, Matsya (or Machcha), Panchala, Surasena, Vṛji, and Vatsa. This period saw the second major rise of urbanism in India after the Indus Valley Civilisation.

Early "republics" or gaṇasaṅgha, such as Shakyas, Koliyas, Mallakas, and Licchavis had republican governments. Gaṇasaṅghas, such as the Mallakas, centered in the city of Kusinagara, and the Vajjika League, centred in the city of Vaishali, existed as early as the 6th century BCE and persisted in some areas until the 4th century CE. The most famous clan amongst the ruling confederate clans of the Vajji Mahajanapada were the Licchavis.

This period corresponds in an archaeological context to the Northern Black Polished Ware culture. Especially focused in the Central Ganges plain but also spreading across vast areas of the northern and central Indian subcontinent, this culture is characterised by the emergence of large cities with massive fortifications, significant population growth, increased social stratification, wide-ranging trade networks, construction of public architecture and water channels, specialised craft industries, a system of weights, punch-marked coins, and the introduction of writing in the form of Brahmi and Kharosthi scripts. The language of the gentry at that time was Sanskrit, while the languages of the general population of northern India are referred to as Prakrits.

Many of the sixteen kingdoms had merged into four major ones by the time of Gautama Buddha. These four were Vatsa, Avanti, Kosala, and Magadha.

Early Magadha dynasties

Magadha formed one of the sixteen Mahajanapadas (Sanskrit: "Great Realms") or kingdoms in ancient India. The core of the kingdom was the area of Bihar south of the Ganges; its first capital was Rajagriha (modern Rajgir) then Pataliputra (modern Patna). Magadha expanded to include most of Bihar and Bengal with the conquest of Licchavi and Anga respectively, followed by much of eastern Uttar Pradesh and Orissa. The ancient kingdom of Magadha is heavily mentioned in Jain and Buddhist texts. It is also mentioned in the Ramayana, Mahabharata and Puranas. The earliest reference to the Magadha people occurs in the Atharva-Veda where they are found listed along with the Angas, Gandharis, and Mujavats. Magadha played an important role in the development of Jainism and Buddhism. Republican communities (such as the community of Rajakumara) are merged into Magadha kingdom. Villages had their own assemblies under their local chiefs called Gramakas. Their administrations were divided into executive, judicial, and military functions.

Early sources, from the Buddhist Pāli Canon, the Jain Agamas and the Hindu Puranas, mention Magadha being ruled by the Pradyota dynasty and Haryanka dynasty (c. 544–413 BCE) for some 200 years, c. 600–413 BCE. King Bimbisara of the Haryanka dynasty led an active and expansive policy, conquering Anga in what is now eastern Bihar and West Bengal. King Bimbisara was overthrown and killed by his son, Prince Ajatashatru, who continued the expansionist policy of Magadha. During this period, Gautama Buddha, the founder of Buddhism, lived much of his life in the Magadha kingdom. He attained enlightenment in Bodh Gaya, gave his first sermon in Sarnath and the first Buddhist council was held in Rajgriha. The Haryanka dynasty was overthrown by the Shaishunaga dynasty (c. 413–345 BCE). The last Shishunaga ruler, Kalasoka, was assassinated by Mahapadma Nanda in 345 BCE, the first of the so-called Nine Nandas (Mahapadma Nanda and his eight sons).

Nanda Empire and Alexander's campaign

The Nanda Empire built on the foundations laid by their Haryanka and Shishunaga predecessors. The empire had a vast army, consisting of 200,000 infantry, 20,000 cavalry, 2,000 war chariots and 3,000 war elephants (at the lowest estimates).

The Indian campaign of Alexander the Great began in 327 BC and lasted until 325 BC. Within two years, Alexander expanded the Macedonian Empire to include Gandhara, including the city of Taxila, and the Indus Valley of Punjab and Sindh.

Alexander and his troops first absorbed the region of Gandhara and then advanced into Punjab, where they were confronted by Porus, the regional Indian king. In 326 BC, Alexander defeated Porus and the Pauravas during the Battle of the Hydaspes.

Alexander's continued eastward march was leading his army into a confrontation with the Nanda Empire. Alexander's troops—increasingly exhausted, homesick, and anxious by the prospects of having to further face large Indian armies throughout the Indo-Gangetic Plain—mutinied at the Hyphasis River, refusing to advance his push to the east. After a meeting with his army general Coenus, during which he was informed of his soldiers' laments. Alexander relented under the conviction that it was better to return. He subsequently turned southward, advancing through southern Punjab as well as Sindh, where he conquered more tribes along the lower areas of the Indus River, before finally turning westward to reach Macedon.

Maurya Empire

The Maurya Empire (322–185 BCE) unified most of the Indian subcontinent into one state, and was the largest empire to exist in South Asia. At its greatest extent, the Mauryan Empire stretched to the north up to the natural boundaries of the Himalayas and to the east into what is now Assam. To the west, it reached beyond modern Pakistan, to the Hindu Kush mountains in what is now Afghanistan. The empire was established by Chandragupta Maurya assisted by Chanakya (Kautilya) in Magadha (in modern Bihar) when he overthrew the Nanda Empire.

Chandragupta rapidly expanded his power westwards across central and western India, and by 317 BCE the empire had fully occupied north-western India. He was successful in his campaign against Seleucus I, founder of the Seleucid Empire, during the Seleucid–Mauryan war in 305 BCE. Under the peace treaty negotiated in 303 BCE the Mauryan Empire gained additional territory west of the Indus River. Chandragupta's son Bindusara succeeded to the throne around 297 BCE. By the time he died in c. 272 BCE, a large part of the Indian subcontinent was under Mauryan suzerainty. However, the region of Kalinga (around modern day Odisha) remained outside Mauryan control, perhaps interfering with trade with the south.

Bindusara was succeeded by Ashoka, whose reign lasted until his death in about 232 BCE. His campaign against the Kalingans in about 260 BCE, though successful, led to immense loss of life and misery. This led Ashoka to shun violence, and subsequently to embrace Buddhism. The empire began to decline after his death and the last Mauryan ruler, Brihadratha, was assassinated by Pushyamitra Shunga to establish the Shunga Empire.

Under Chandragupta Maurya and his successors, internal and external trade, agriculture, and economic activities all thrived and expanded across India thanks to the creation of a single efficient system of finance, administration, and security. The Mauryans built the precursor of the modern Grand Trunk Road, one of Asia's oldest and longest major roads connecting the Indian subcontinent with Central Asia. After the Kalinga War, the Empire experienced nearly half a century of peace and security under Ashoka. Mauryan India also enjoyed an era of social harmony, religious transformation, and expansion of scientific knowledge. Chandragupta Maurya's embrace of Jainism increased social and religious renewal and reform across his society, while Ashoka's embrace of Buddhism has been said to have been the foundation of the reign of social and political peace and non-violence across India. Ashoka sponsored Buddhist missions across the Indo-Mediterranean, into Sri Lanka, Southeast Asia, West Asia, North Africa, and Mediterranean Europe.

The Arthashastra and the Edicts of Ashoka are the primary written records of the Mauryan times. Archaeologically, this period falls in the era of Northern Black Polished Ware. The Mauryan Empire had a highly organised administrative system, with considerable state involvement in economic activities and the regulation of trade. Although there was no banking in the Mauryan society, usury was customary. A significant amount of written records on slavery are found, suggesting a prevalence thereof. During this period, a high-quality steel called Wootz steel was developed in south India and was later exported to China and Arabia.

Sangam period

During the Sangam period Tamil literature flourished from the 3rd century BCE to the 4th century CE. Three Tamil dynasties, collectively known as the Three Crowned Kings of Tamilakam: the Chera dynasty, Chola dynasty, and Pandya dynasty ruled parts of southern India.

The Sangam literature deals with the history, politics, wars, and culture of the Tamil people of this period. Unlike Sanskrit writers who were mostly Brahmins, Sangam writers came from diverse classes and social backgrounds and were mostly non-Brahmins.

Around c. 300 BCE – c. 200 CE, Pathupattu, an anthology of ten mid-length book collections, which is considered part of Sangam Literature, were composed; the composition of eight anthologies of poetic works Ettuthogai as well as the composition of eighteen minor poetic works Patiṉeṇkīḻkaṇakku; while Tolkāppiyam, the earliest grammarian work in the Tamil language was developed. Also, during the Sangam period, two of the Five Great Epics of Tamil Literature were composed. Ilango Adigal composed Silappatikaram, which is a non-religious work, that revolves around Kannagi, and Manimekalai, composed by Chithalai Chathanar, is a sequel to Silappatikaram, and tells the story of the daughter of Kovalan and Madhavi, who became a Buddhist Bhikkhuni.

Classical period (c. 200 BCE – 650 CE)

The time between the Maurya Empire in the 3rd century BCE and the end of the Gupta Empire in the 6th century CE is referred to as the "Classical" period of India. The Gupta Empire (4th–6th century) is regarded as the Golden Age of India, although a host of kingdoms ruled over India in these centuries. Also, the Sangam literature flourished from the 3rd century BCE to the 3rd century CE in southern India. During this period, India's economy is estimated to have been the largest in the world, having between one-third and one-quarter of the world's wealth, from 1 CE to 1000 CE.

Early classical period (c. 200 BCE – 320 CE)

Shunga Empire

The Shungas originated from Magadha, and controlled large areas of the central and eastern Indian subcontinent from around 187 to 78 BCE. The dynasty was established by Pushyamitra Shunga, who overthrew the last Maurya emperor. Its capital was Pataliputra, but later emperors, such as Bhagabhadra, also held court at Vidisha, modern Besnagar.

Pushyamitra Shunga ruled for 36 years and was succeeded by his son Agnimitra. There were ten Shunga rulers. However, after the death of Agnimitra, the empire rapidly disintegrated; inscriptions and coins indicate that much of northern and central India consisted of small kingdoms and city-states that were independent of any Shunga hegemony. The empire is noted for its numerous wars with both foreign and indigenous powers. They fought with the Mahameghavahana dynasty of Kalinga, Satavahana dynasty of Deccan, the Indo-Greeks, and possibly the Panchalas and Mitras of Mathura.

Art, education, philosophy, and other forms of learning flowered during this period including architectural monuments such as the Stupa at Bharhut and the renowned Great Stupa at Sanchi. The Shunga rulers helped to establish the tradition of royal sponsorship of learning and art. The script used by the empire was a variant of Brahmi and was used to write the Sanskrit language. The Shunga Empire played an imperative role in patronising Indian culture at a time when some of the most important developments in Hindu thought were taking place.

Satavahana Empire

The Śātavāhanas were based from Amaravati in Andhra Pradesh as well as Junnar (Pune) and Prathisthan (Paithan) in Maharashtra. The territory of the empire covered large parts of India from the 1st century BCE onward. The Sātavāhanas started out as feudatories to the Mauryan dynasty, but declared independence with its decline.

The Sātavāhanas are known for their patronage of Hinduism and Buddhism, which resulted in Buddhist monuments from Ellora (a UNESCO World Heritage Site) to Amaravati. They were one of the first Indian states to issue coins with their rulers embossed. They formed a cultural bridge and played a vital role in trade as well as the transfer of ideas and culture to and from the Indo-Gangetic Plain to the southern tip of India.

They had to compete with the Shunga Empire and then the Kanva dynasty of Magadha to establish their rule. Later, they played a crucial role to protect large part of India against foreign invaders like the Sakas, Yavanas and Pahlavas. In particular, their struggles with the Western Kshatrapas went on for a long time. The notable rulers of the Satavahana Dynasty Gautamiputra Satakarni and Sri Yajna Sātakarni were able to defeat the foreign invaders like the Western Kshatrapas and to stop their expansion. In the 3rd century CE, the empire was split into smaller states.

Trade and travels to India

The spice trade in Kerala attracted traders from all over the Old World to India. India's Southwest coastal port Muziris had established itself as a major spice trade centre from as early as 3,000 BCE, according to Sumerian records. Jewish traders arrived in Kochi, Kerala, India as early as 562 BCE. The Greco-Roman world followed by trading along the incense route and the Indo-Roman routes. During the 2nd century BCE Greek and Indian ships met to trade at Arabian ports such as Aden. During the first millennium, the sea routes to India were controlled by the Indians and Ethiopians that became the maritime trading power of the Red Sea.

Indian merchants involved in spice trade took Indian cuisine to Southeast Asia, where spice mixtures and curries became popular with the native inhabitants. Buddhism entered China through the Silk Road in the 1st or 2nd century CE. Hindu and Buddhist religious establishments of South and Southeast Asia came to be centres of production and commerce as they accumulated capital donated by patrons. They engaged in estate management, craftsmanship, and trade. Buddhism in particular travelled alongside the maritime trade, promoting literacy, art, and the use of coinage.

Kushan Empire

The Kushan Empire expanded out of what is now Afghanistan into the northwest of the Indian subcontinent under the leadership of their first emperor, Kujula Kadphises, about the middle of the 1st century CE. The Kushans were possibly a Tocharian speaking tribe, one of five branches of the Yuezhi confederation. By the time of his grandson, Kanishka the Great, the empire spread to encompass much of Afghanistan, and then the northern parts of the Indian subcontinent.

Emperor Kanishka was a great patron of Buddhism; however, as Kushans expanded southward, the deities of their later coinage came to reflect its new Hindu majority. Historian Vincent Smith said about Kanishka:

He played the part of a second Ashoka in the history of Buddhism.

The empire linked the Indian Ocean maritime trade with the commerce of the Silk Road through the Indus valley, encouraging long-distance trade, particularly between China and Rome. The Kushans brought new trends to the budding and blossoming Gandhara art and Mathura art, which reached its peak during Kushan rule. The period of peace under Kushan rule is known as Pax Kushana. By the 3rd century, their empire in India was disintegrating and their last known great emperor was Vasudeva I.

Classical period (c. 320 – 650 CE)

Gupta Empire

The Gupta period was noted for cultural creativity, especially in literature, architecture, sculpture, and painting. The Gupta period produced scholars such as Kalidasa, Aryabhata, Varahamihira, Vishnu Sharma, and Vatsyayana. The Gupta period marked a watershed of Indian culture: the Guptas performed Vedic sacrifices to legitimise their rule, but they also patronised Buddhism, an alternative to Brahmanical orthodoxy. The military exploits of the first three rulers – Chandragupta I, Samudragupta, and Chandragupta II – brought much of India under their leadership. Science and political administration reached new heights during the Gupta era. Strong trade ties also made the region an important cultural centre and established it as a base that would influence nearby kingdoms and regions. The period of peace under Gupta rule is known as Pax Gupta.

The latter Guptas successfully resisted the northwestern kingdoms until the arrival of the Alchon Huns, who established themselves in Afghanistan by the first half of the 5th century CE, with their capital at Bamiyan. However, much of the southern India including Deccan were largely unaffected by these events.

Vakataka Empire

The Vākāṭaka Empire originated from the Deccan in the mid-third century CE. Their state is believed to have extended from the southern edges of Malwa and Gujarat in the north to the Tungabhadra River in the south as well as from the Arabian Sea in the western to the edges of Chhattisgarh in the east. They were the most important successors of the Satavahanas in the Deccan, contemporaneous with the Guptas in northern India and succeeded by the Vishnukundina dynasty.

The Vakatakas are noted for having been patrons of the arts, architecture and literature. The rock-cut Buddhist viharas and chaityas of Ajanta Caves (a UNESCO World Heritage Site) were built under the patronage of Vakataka emperor, Harishena.

Kamarupa Kingdom

Samudragupta's 4th-century Allahabad pillar inscription mentions Kamarupa (Western Assam) and Davaka (Central Assam) as frontier kingdoms of the Gupta Empire. Davaka was later absorbed by Kamarupa, which grew into a large kingdom that spanned from Karatoya river to near present Sadiya and covered the entire Brahmaputra valley, North Bengal, parts of Bangladesh and, at times Purnea and parts of West Bengal.

Ruled by three dynasties Varmanas (c. 350–650 CE), Mlechchha dynasty (c. 655–900 CE) and Kamarupa-Palas (c. 900–1100 CE), from their capitals in present-day Guwahati (Pragjyotishpura), Tezpur (Haruppeswara) and North Gauhati (Durjaya) respectively. All three dynasties claimed their descent from Narakasura. In the reign of the Varman king, Bhaskar Varman (c. 600–650 CE), the Chinese traveller Xuanzang visited the region and recorded his travels. Later, after weakening and disintegration (after the Kamarupa-Palas), the Kamarupa tradition was somewhat extended until c. 1255 CE by the Lunar I (c. 1120–1185 CE) and Lunar II (c. 1155–1255 CE) dynasties. The Kamarupa kingdom came to an end in the middle of the 13th century when the Khen dynasty under Sandhya of Kamarupanagara (North Guwahati), moved his capital to Kamatapur (North Bengal) after the invasion of Muslim Turks, and established the Kamata kingdom.

Pallava Empire

The Pallavas, during the 4th to 9th centuries were, alongside the Guptas of the North, great patronisers of Sanskrit development in the South of the Indian subcontinent. The Pallava reign saw the first Sanskrit inscriptions in a script called Grantha. Early Pallavas had different connexions to Southeast Asian countries. The Pallavas used Dravidian architecture to build some very important Hindu temples and academies in Mamallapuram, Kanchipuram and other places; their rule saw the rise of great poets. The practice of dedicating temples to different deities came into vogue followed by fine artistic temple architecture and sculpture style of Vastu Shastra.

Pallavas reached the height of power during the reign of Mahendravarman I (571–630 CE) and Narasimhavarman I (630–668 CE) and dominated the Telugu and northern parts of the Tamil region until the end of the 9th century.

Kadamba Empire

Kadambas originated from Karnataka, was founded by Mayurasharma in 345 CE which at later times showed the potential of developing into imperial proportions. King Mayurasharma defeated the armies of Pallavas of Kanchi possibly with help of some native tribes. The Kadamba fame reached its peak during the rule of Kakusthavarma, a notable ruler with whom the kings of Gupta Dynasty of northern India cultivated marital alliances. The Kadambas were contemporaries of the Western Ganga Dynasty and together they formed the earliest native kingdoms to rule the land with absolute autonomy. The dynasty later continued to rule as a feudatory of larger Kannada empires, the Chalukya and the Rashtrakuta empires, for over five hundred years during which time they branched into minor dynasties (Kadambas of Goa, Kadambas of Halasi and Kadambas of Hangal).

Empire of Harsha

Harsha ruled northern India from 606 to 647 CE. He was the son of Prabhakarvardhana and the younger brother of Rajyavardhana, who were members of the Vardhana dynasty and ruled Thanesar, in present-day Haryana.

After the downfall of the prior Gupta Empire in the middle of the 6th century, North India reverted to smaller republics and monarchical states. The power vacuum resulted in the rise of the Vardhanas of Thanesar, who began uniting the republics and monarchies from the Punjab to central India. After the death of Harsha's father and brother, representatives of the empire crowned Harsha emperor in April 606 CE, giving him the title of Maharaja. At the peak, his Empire covered much of North and Northwestern India, extended East until Kamarupa, and South until Narmada River; and eventually made Kannauj (in present Uttar Pradesh) his capital, and ruled until 647 CE.

The peace and prosperity that prevailed made his court a centre of cosmopolitanism, attracting scholars, artists and religious visitors. During this time, Harsha converted to Buddhism from Hinduism. The Chinese traveller Xuanzang visited the court of Harsha and wrote a very favourable account of him, praising his justice and generosity. His biography Harshacharita ("Deeds of Harsha") written by Sanskrit poet Banabhatta, describes his association with Thanesar and the palace with a two-storied Dhavalagriha (White Mansion).

Early medieval period (c. 650 – 1200)

Early medieval India began after the end of the Gupta Empire in the 6th century CE. This period also covers the "Late Classical Age" of Hinduism, which began after the collapse of the Empire of Harsha in the 7th century, and ended in the 13th century with the rise of the Delhi Sultanate in Northern India; the beginning of Imperial Kannauj, leading to the Tripartite struggle; and the end of the Later Cholas with the death of Rajendra Chola III in 1279 in Southern India; however some aspects of the Classical period continued until the fall of the Vijayanagara Empire in the south around the 17th century.

From the fifth century to the thirteenth, Śrauta sacrifices declined, and support for Shaivism, Vaishnavism, and Shaktism expanded in royal courts, while the support for Buddhism declined. Lack of appeal among the rural masses, who instead embraced Brahmanical Hinduism formed in the Hindu synthesis, and dwindling financial support from trading communities and royal elites, were major factors in the decline of Buddhism.

In the 7th century, Kumārila Bhaṭṭa formulated his school of Mimamsa philosophy and defended the position on Vedic rituals.

From the 8th to the 10th century, three dynasties contested for control of northern India: the Gurjara Pratiharas of Malwa, the Palas of Bengal, and the Rashtrakutas of the Deccan. The Sena dynasty would later assume control of the Pala Empire; the Gurjara Pratiharas fragmented into various states, notably the Kingdom of Malwa, the Kingdom of Bundelkhand, the Kingdom of Dahala, the Tomaras of Haryana, and the Kingdom of Sambhar, these states were some of the earliest Rajput kingdoms; while the Rashtrakutas were annexed by the Western Chalukyas. During this period, the Chaulukya dynasty emerged; the Chaulukyas constructed the Dilwara Temples, Modhera Sun Temple, Rani ki vav in the style of Māru-Gurjara architecture, and their capital Anhilwara (modern Patan, Gujarat) was one of the largest cities in the Indian subcontinent, with the population estimated at 100,000 in c. 1000. Patan's rise also marked the revival of Jainism in Gujarat during the times of Hemchandracharya. It became renowned for its collection of ancient Jain manuscripts and an important centre of Jain learning, which drew the admiration of many scholars. British Indologist and Sanskritist Peter Peterson described the collection as follows:

I know of no town in India and only a few in the world which can boast of so great a store documents of venerable antiquity. They would be the pride and jealously guarded treasure of any University Library in Europe.

The Chola Empire emerged as a major power during the reign of Raja Raja Chola I and Rajendra Chola I who successfully invaded parts of Southeast Asia and Sri Lanka in the 11th century. Lalitaditya Muktapida (r. 724–760) was an emperor of the Kashmiri Karkoṭa dynasty, which exercised influence in northwestern India from 625 until 1003, and was followed by Lohara dynasty. Kalhana in his Rajatarangini credits king Lalitaditya with leading an aggressive military campaign in Northern India and Central Asia.

The Hindu Shahi dynasty ruled portions of eastern Afghanistan, northern Pakistan, and Kashmir from the mid-7th century to the early 11th century. While in Odisha, the Eastern Ganga Empire rose to power; noted for the advancement of Hindu architecture, most notable being Jagannath Temple and Konark Sun Temple, as well as being patrons of art and literature.

Later Gupta dynasty

The Later Gupta dynasty ruled the Magadha region in eastern India between the 6th and 7th centuries CE. The Later Guptas succeeded the imperial Guptas as the rulers of Magadha, but there is no evidence connecting the two dynasties; these appear to be two distinct families. The Later Guptas are so-called because the names of their rulers ended with the suffix "-gupta", which they might have adopted to portray themselves as the legitimate successors of the imperial Guptas.

Chalukya Empire

The Chalukya Empire ruled large parts of southern and central India between the 6th and the 12th centuries, as three related yet individual dynasties. The earliest dynasty, known as the "Badami Chalukyas", ruled from Vatapi (modern Badami) from the middle of the 6th century. The Badami Chalukyas began to assert their independence at the decline of the Kadamba kingdom of Banavasi and rapidly rose to prominence during the reign of Pulakeshin II. The rule of the Chalukyas marks an important milestone in the history of South India and a golden age in the history of Karnataka. The political atmosphere in South India shifted from smaller kingdoms to large empires with the ascendancy of Badami Chalukyas. A Southern India-based kingdom took control and consolidated the entire region between the Kaveri and the Narmada Rivers. The rise of this empire saw the birth of efficient administration, overseas trade and commerce and the development of new style of architecture called "Chalukyan architecture". The Chalukya dynasty ruled parts of southern and central India from Badami in Karnataka between 550 and 750, and then again from Kalyani between 970 and 1190.

Rashtrakuta Empire

Founded by Dantidurga around 753, the Rashtrakuta Empire ruled from its capital at Manyakheta for almost two centuries. At its peak, the Rashtrakutas ruled from the Ganges-Yamuna Doab in the north to Cape Comorin in the south, a fruitful time of architectural and literary achievements.

The early rulers of this dynasty were Hindu, but the later rulers were strongly influenced by Jainism. Govinda III and Amoghavarsha were the most famous of the long line of able administrators produced by the dynasty. Amoghavarsha was also an author and wrote Kavirajamarga, the earliest known Kannada work on poetics. Architecture reached a milestone in the Dravidian style, the finest example of which is seen in the Kailasanath Temple at Ellora. Other important contributions are the Kashivishvanatha temple and the Jain Narayana temple at Pattadakal in Karnataka.

The Arab traveller Suleiman described the Rashtrakuta Empire as one of the four great Empires of the world. The Rashtrakuta period marked the beginning of the golden age of southern Indian mathematics. The great south Indian mathematician Mahāvīra had a huge impact on medieval south Indian mathematicians. The Rashtrakuta rulers also patronised men of letters in a variety of languages.

Gurjara-Pratihara Empire

The Gurjara-Pratiharas were instrumental in containing Arab armies moving east of the Indus River. Nagabhata I defeated the Arab army under Junaid and Tamin during the Umayyad campaigns in India. Under Nagabhata II, the Gurjara-Pratiharas became the most powerful dynasty in northern India. He was succeeded by his son Ramabhadra, who ruled briefly before being succeeded by his son, Mihira Bhoja. Under Bhoja and his successor Mahendrapala I, the Pratihara Empire reached its peak of prosperity and power. By the time of Mahendrapala, its territory stretched from the border of Sindh in the west to Bihar in the east and from the Himalayas in the north to around the Narmada River in the south. The expansion triggered a tripartite power struggle with the Rashtrakuta and Pala empires for control of the Indian subcontinent.

By the end of the 10th century, several feudatories of the empire took advantage of the temporary weakness of the Gurjara-Pratiharas to declare their independence, notably the Kingdom of Malwa, the Kingdom of Bundelkhand, the Tomaras of Haryana, and the Kingdom of Sambhar and the Kingdom of Dahala.

Gahadavala dynasty

Gahadavala dynasty ruled parts of the present-day Indian states of Uttar Pradesh and Bihar, during 11th and 12th centuries. Their capital was located at Varanasi.

Karnat dynasty

In 1097 CE, the Karnat dynasty of Mithila emerged on the Bihar/Nepal border area and maintained capitals in Darbhanga and Simraongadh. The dynasty was established by Nanyadeva, a military commander of Karnataka origin. Under this dynasty, the Maithili language started to develop with the first piece of Maithili literature, the Varna Ratnakara being produced in the 14th century by Jyotirishwar Thakur. The Karnats also carried out raids into Nepal. They fell in 1324 following the invasion of Ghiyasuddin Tughlaq.

Pala Empire

The Pala Empire was founded by Gopala I. It was ruled by a Buddhist dynasty from Bengal. The Palas reunified Bengal after the fall of Shashanka's Gauda Kingdom.

The Palas were followers of the Mahayana and Tantric schools of Buddhism, they also patronised Shaivism and Vaishnavism. The empire reached its peak under Dharmapala and Devapala. Dharmapala is believed to have conquered Kanauj and extended his sway up to the farthest limits of India in the north-west.

The Pala Empire can be considered as the golden era of Bengal. Dharmapala founded the Vikramashila and revived Nalanda, considered one of the first great universities in recorded history. Nalanda reached its height under the patronage of the Pala Empire. The Palas also built many viharas. They maintained close cultural and commercial ties with countries of Southeast Asia and Tibet. Sea trade added greatly to the prosperity of the Pala Empire.

Cholas

Medieval Cholas rose to prominence during the middle of the 9th century and established the greatest empire South India had seen. They successfully united the South India under their rule and through their naval strength extended their influence in the Southeast Asian countries such as Srivijaya. Under Rajaraja Chola I and his successors Rajendra Chola I, Rajadhiraja Chola, Virarajendra Chola and Kulothunga Chola I the dynasty became a military, economic and cultural power in South and Southeast Asia. Rajendra Chola I's navies occupied the sea coasts from Burma to Vietnam, the Andaman and Nicobar Islands, the Lakshadweep (Laccadive) islands, Sumatra, and the Malay Peninsula. The power of the new empire was proclaimed to the eastern world by the expedition to the Ganges which Rajendra Chola I undertook and by the occupation of cities of the maritime empire of Srivijaya in Southeast Asia, as well as by the repeated embassies to China.

They dominated the political affairs of Sri Lanka for over two centuries through repeated invasions and occupation. They also had continuing trade contacts with the Arabs and the Chinese empire. Rajaraja Chola I and his son Rajendra Chola I gave political unity to the whole of Southern India and established the Chola Empire as a respected sea power. Under the Cholas, the South India reached new heights of excellence in art, religion and literature. In all of these spheres, the Chola period marked the culmination of movements that had begun in an earlier age under the Pallavas. Monumental architecture in the form of majestic temples and sculpture in stone and bronze reached a finesse never before achieved in India.

Western Chalukya Empire

The Western Chalukya Empire ruled most of the western Deccan, South India, between the 10th and 12th centuries. Vast areas between the Narmada River in the north and Kaveri River in the south came under Chalukya control. During this period the other major ruling families of the Deccan, the Hoysalas, the Seuna Yadavas of Devagiri, the Kakatiya dynasty and the Southern Kalachuris, were subordinates of the Western Chalukyas and gained their independence only when the power of the Chalukya waned during the latter half of the 12th century.

The Western Chalukyas developed an architectural style known today as a transitional style, an architectural link between the style of the early Chalukya dynasty and that of the later Hoysala empire. Most of its monuments are in the districts bordering the Tungabhadra River in central Karnataka. Well known examples are the Kasivisvesvara Temple at Lakkundi, the Mallikarjuna Temple at Kuruvatti, the Kallesvara Temple at Bagali, Siddhesvara Temple at Haveri, and the Mahadeva Temple at Itagi. This was an important period in the development of fine arts in Southern India, especially in literature as the Western Chalukya kings encouraged writers in the native language of Kannada, and Sanskrit like the philosopher and statesman Basava and the great mathematician Bhāskara II.

Late medieval period (c. 1200 – 1526)

The late medieval period is marked by repeated invasions by Muslim Central Asian nomadic clans, the rule of the Delhi Sultanate, and by the growth of other states, built upon military technology of the sultanate.

Delhi Sultanate

The Delhi Sultanate was a series of successive Islamic states based in Delhi, ruled by several dynasties of varying origins. The polity ruled over large parts of the Indian subcontinent from the 13th to early 16th centuries. The sultanate was founded in the 12th and 13th centuries by Central Asian Turks, who invaded parts of northern India and established the state atop former Hindu holdings. The subsequent Mamluk dynasty of Delhi managed to conquer large areas of northern India. The Khalji dynasty conquered much of central India while forcing the principal Hindu kingdoms of South India to become vassal states.

The sultanate ushered in a period of Indian cultural renaissance. The resulting "Indo-Muslim" fusion of cultures left lasting syncretic monuments in architecture, music, literature, religion, and clothing. It is surmised that the language of Urdu was born during the period of the Delhi Sultanate. The sultanate was the only Indo-Islamic state to enthrone one of the few female rulers in India, Razia Sultana (r. 1236–1240).

While initially disruptive due to the passing of power from native Indian elites to Turkic Muslim elites, the Delhi Sultanate was responsible for integrating the Indian subcontinent into a growing world system, drawing India into a wider international network, which had a significant impact on Indian culture and society. However, the Delhi Sultanate also caused large-scale destruction and desecration of temples in the Indian subcontinent.

The Mongol invasions of India were successfully repelled by the Delhi Sultanate during the rule of Alauddin Khalji. A major factor in their success was their Turkic Mamluk slave army, who were highly skilled in the same style of nomadic cavalry warfare as the Mongols. It is possible that the Mongol Empire may have expanded into India were it not for the Delhi Sultanate's role in repelling them. By repeatedly repulsing the Mongol raiders, the sultanate saved India from the devastation waged on West and Central Asia. Soldiers from that region and learned men and administrators fleeing Mongol invasions of Iran migrated into the subcontinent, thereby creating a syncretic Indo-Islamic culture in the north.

A Turco-Mongol conqueror from Central Asia, Timur (Tamerlane), attacked the reigning sultan Nasir-u Din Mehmud of the Tughlaq dynasty in Delhi. The sultan's army was defeated on 17 December 1398. Timur entered Delhi and the city was sacked, destroyed, and left in ruins after Timur's army had killed and plundered for three days and nights. He ordered the whole city to be sacked except for the sayyids, scholars, and the "other Muslims" (artists); 100,000 war prisoners were said to have been put to death in one day. The sultanate suffered significantly from the sacking of Delhi. Though revived briefly under the Sayyid and Lodi dynasties, it was but a shadow of the former. Lodi rule lasted in Delhi until the defeat of the last sultan, Ibrahim Khan Lodi, in 1526 to the forces of Babur.

Vijayanagara Empire

The Vijayanagara Empire was established in 1336 by Harihara I and his brother Bukka Raya I of Sangama Dynasty, which originated as a political heir of the Hoysala Empire, Kakatiya Empire, and the Pandyan Empire. The empire rose to prominence as a culmination of attempts by the south Indian powers to ward off Islamic invasions by the end of the 13th century. It lasted until 1646, although its power declined after a major military defeat in 1565 by the combined armies of the Deccan sultanates. The empire is named after its capital city of Vijayanagara, whose ruins surround present day Hampi, now a World Heritage Site in Karnataka, India.

In the first two decades after the founding of the empire, Harihara I gained control over most of the area south of the Tungabhadra river and earned the title of Purvapaschima Samudradhishavara ("master of the eastern and western seas"). By 1374 Bukka Raya I, successor to Harihara I, had defeated the chiefdom of Arcot, the Reddys of Kondavidu, and the Sultan of Madurai and had gained control over Goa in the west and the Tungabhadra-Krishna doab in the north.

Harihara II, the second son of Bukka Raya I, further consolidated the kingdom beyond the Krishna River and brought the whole of South India under the Vijayanagara umbrella. The next ruler, Deva Raya I, emerged successful against the Gajapatis of Odisha and undertook important works of fortification and irrigation. Italian traveller Niccolo de Conti wrote of him as the most powerful ruler of India. Deva Raya II succeeded to the throne in 1424 and was possibly the most capable of the Sangama Dynasty rulers. He quelled rebelling feudal lords as well as the Zamorin of Calicut and Quilon in the south. He invaded the island of Sri Lanka and became overlord of the kings of Burma at Pegu and Tanasserim.

The Vijayanagara Emperors were tolerant of all religions and sects, as writings by foreign visitors show. The kings used titles such as Gobrahamana Pratipalanacharya (literally, "protector of cows and Brahmins") and Hindurayasuratrana (lit, "upholder of Hindu faith") that testified to their intention of protecting Hinduism and yet were at the same time staunchly Islamicate in their court ceremonials and dress. The empire's founders, Harihara I and Bukka Raya I, were devout Shaivas (worshippers of Shiva), but made grants to the Vaishnava order of Sringeri with Vidyaranya as their patron saint, and designated Varaha (an avatar of Vishnu) as their emblem. Nobles from Central Asia's Timurid kingdoms also came to Vijayanagara. The later Saluva and Tuluva kings were Vaishnava by faith, but worshipped at the feet of Lord Virupaksha (Shiva) at Hampi as well as Lord Venkateshwara (Vishnu) at Tirupati. A Sanskrit work, Jambavati Kalyanam by King Krishnadevaraya, called Lord Virupaksha Karnata Rajya Raksha Mani ("protective jewel of Karnata Empire"). The kings patronised the saints of the dvaita order (philosophy of dualism) of Madhvacharya at Udupi.

The empire's legacy includes many monuments spread over South India, the best known of which is the group at Hampi. The previous temple building traditions in South India came together in the Vijayanagara architecture style. The mingling of all faiths and vernaculars inspired architectural innovation of Hindu temple construction. South Indian mathematics flourished under the protection of the Vijayanagara Empire in Kerala. The south Indian mathematician Madhava of Sangamagrama founded the famous Kerala School of Astronomy and Mathematics in the 14th century which produced a lot of great south Indian mathematicians like Parameshvara, Nilakantha Somayaji and Jyeṣṭhadeva. Efficient administration and vigorous overseas trade brought new technologies such as water management systems for irrigation. The empire's patronage enabled fine arts and literature to reach new heights in Kannada, Telugu, Tamil, and Sanskrit, while Carnatic music evolved into its current form.

Vijayanagara went into decline after the defeat in the Battle of Talikota (1565). After the death of Aliya Rama Raya in the Battle of Talikota, Tirumala Deva Raya started the Aravidu dynasty, moved and founded a new capital of Penukonda to replace the destroyed Hampi, and attempted to reconstitute the remains of Vijayanagara Empire. Tirumala abdicated in 1572, dividing the remains of his kingdom to his three sons, and pursued a religious life until his death in 1578. The Aravidu dynasty successors ruled the region but the empire collapsed in 1614, and the final remains ended in 1646, from continued wars with the Bijapur sultanate and others. During this period, more kingdoms in South India became independent and separate from Vijayanagara. These include the Mysore Kingdom, Keladi Nayaka, Nayaks of Madurai, Nayaks of Tanjore, Nayakas of Chitradurga and Nayak Kingdom of Gingee – all of which declared independence and went on to have a significant impact on the history of South India in the coming centuries.

Other kingdoms

For two and a half centuries from the mid-13th century, politics in Northern India was dominated by the Delhi Sultanate, and in Southern India by the Vijayanagar Empire. However, there were other regional powers present as well. After fall of Pala Empire, the Chero dynasty ruled much of Eastern Uttar Pradesh, Bihar and Jharkhand from the 12th to the 18th centuries. The Reddy dynasty successfully defeated the Delhi Sultanate and extended their rule from Cuttack in the north to Kanchi in the south, eventually being absorbed into the expanding Vijayanagara Empire.

In the north, the Rajput kingdoms remained the dominant force in Western and Central India. The Mewar dynasty under Maharana Hammir defeated and captured Muhammad Tughlaq with the Bargujars as his main allies. Tughlaq had to pay a huge ransom and relinquish all of Mewar's lands. After this event, the Delhi Sultanate did not attack Chittor for a few hundred years. The Rajputs re-established their independence, and Rajput states were established as far east as Bengal and north into the Punjab. The Tomaras established themselves at Gwalior, and Man Singh Tomar reconstructed the Gwalior Fort. During this period, Mewar emerged as the leading Rajput state; and Rana Kumbha expanded his kingdom at the expense of the Sultanates of Malwa and Gujarat. The next great Rajput ruler, Rana Sanga of Mewar, became the principal player in Northern India. His objectives grew in scope – he planned to conquer Delhi. But, his defeat in the Battle of Khanwa consolidated the new Mughal dynasty in India. The Mewar dynasty under Maharana Udai Singh II faced further defeat by Mughal emperor Akbar, with their capital Chittor being captured. Due to this event, Udai Singh II founded Udaipur, which became the new capital of the Mewar kingdom. His son, Maharana Pratap of Mewar, firmly resisted the Mughals. Akbar sent many missions against him. He survived to ultimately gain control of all of Mewar, excluding the Chittor Fort.

In the south, the Bahmani Sultanate in the Deccan, born from a rebellion in 1347 against the Tughlaq dynasty, was the chief rival of Vijayanagara, and frequently created difficulties for them. Starting in 1490, the Bahmani Sultanate's governors revolted, their independent states composing the five Deccan sultanates; Ahmadnagar declared independence, followed by Bijapur and Berar in the same year; Golkonda became independent in 1518 and Bidar in 1528. Although generally rivals, they allied against the Vijayanagara Empire in 1565, permanently weakening Vijayanagar in the Battle of Talikota.

In the east, the Gajapati Kingdom remained a strong regional power to reckon with, associated with a high point in the growth of regional culture and architecture. Under Kapilendradeva, Gajapatis became an empire stretching from the lower Ganga in the north to the Kaveri in the south. In Northeast India, the Ahom Kingdom was a major power for six centuries; led by Lachit Borphukan, the Ahoms decisively defeated the Mughal army at the Battle of Saraighat during the Ahom-Mughal conflicts. Further east in Northeastern India was the Kingdom of Manipur, which ruled from their seat of power at Kangla Fort and developed a sophisticated Hindu Gaudiya Vaishnavite culture.

The Sultanate of Bengal was the dominant power of the Ganges–Brahmaputra Delta, with a network of mint towns spread across the region. It was a Sunni Muslim monarchy with Indo-Turkic, Arab, Abyssinian and Bengali Muslim elites. The sultanate was known for its religious pluralism where non-Muslim communities co-existed peacefully. The Bengal Sultanate had a circle of vassal states, including Odisha in the southwest, Arakan in the southeast, and Tripura in the east. In the early 16th century, the Bengal Sultanate reached the peak of its territorial growth with control over Kamrup and Kamata in the northeast and Jaunpur and Bihar in the west. It was reputed as a thriving trading nation and one of Asia's strongest states. The Bengal Sultanate was described by contemporary European and Chinese visitors as a relatively prosperous kingdom and the "richest country to trade with". The Bengal Sultanate left a strong architectural legacy. Buildings from the period show foreign influences merged into a distinct Bengali style. The Bengal Sultanate was also the largest and most prestigious authority among the independent medieval Muslim-ruled states in the history of Bengal. Its decline began with an interregnum by the Suri Empire, followed by Mughal conquest and disintegration into petty kingdoms.

Bhakti movement and Sikhism

The Bhakti movement refers to the theistic devotional trend that emerged in medieval Hinduism and later revolutionised in Sikhism. It originated in the seventh-century south India (now parts of Tamil Nadu and Kerala), and spread northwards. It swept over east and north India from the 15th century onwards, reaching its zenith between the 15th and 17th century.

• The Bhakti movement regionally developed around different gods and goddesses, such as Vaishnavism (Vishnu), Shaivism (Shiva), Shaktism (Shakti goddesses), and Smartism. The movement was inspired by many poet-saints, who championed a wide range of philosophical positions ranging from theistic dualism of Dvaita to absolute monism of Advaita Vedanta.
• Sikhism is a monotheistic and panentheistic religion based on the spiritual teachings of Guru Nanak, the first Guru, and the ten successive Sikh gurus. After the death of the tenth Guru, Guru Gobind Singh, the Sikh scripture, Guru Granth Sahib, became the literal embodiment of the eternal, impersonal Guru, where the scripture's word serves as the spiritual guide for Sikhs.
• Buddhism in India flourished in the Himalayan kingdoms of Namgyal Kingdom in Ladakh, Sikkim Kingdom in Sikkim, and Chutia Kingdom in Arunachal Pradesh of the Late medieval period.

Early modern period (1526–1858)

The early modern period of Indian history is dated from 1526 to 1858, corresponding to the rise and fall of the Mughal Empire, which inherited from the Timurid Renaissance. During this age India's economy expanded, relative peace was maintained and arts were patronised. This period witnessed the further development of Indo-Islamic architecture; the growth of Marathas and Sikhs enabled them to rule significant regions of India in the waning days of the Mughal empire. With the discovery of the Cape Route in the 1500s, the first Europeans to arrive by sea and establish themselves, were the Portuguese in Goa and Bombay.

Mughal Empire

In 1526, Babur swept across the Khyber Pass and established the Mughal Empire, which at its zenith covered much of South Asia. However, his son Humayun was defeated by the Afghan warrior Sher Shah Suri in 1540, and Humayun was forced to retreat to Kabul. After Sher Shah's death, his son Islam Shah Suri and his Hindu general Hemu Vikramaditya established control over much of North India from Delhi until 1556, when Akbar (r. 1556–1605), grandson of Babur, defeated Hemu in the Second Battle of Panipat on 6 November 1556 after winning Battle of Delhi. Akbar tried to establish a good relationship with the Hindus. Akbar declared "Amari" or non-killing of animals in the holy days of Jainism. He rolled back the jizya tax for non-Muslims. The Mughal emperors married local royalty, allied themselves with local maharajas, and attempted to fuse their Turko-Persian culture with ancient Indian styles, creating a unique Indo-Persian culture and Indo-Saracenic architecture.

Akbar married a Rajput princess, Mariam-uz-Zamani, and they had a son, Jahangir (r. 1605–1627). Jahangir followed his father's policy. The Mughal dynasty ruled most of the Indian subcontinent by 1600. The reign of Shah Jahan (r. 1628–1658) was the golden age of Mughal architecture. He erected several large monuments, the most famous of which is the Taj Mahal at Agra.

It was one of the largest empires to have existed in the Indian subcontinent, and surpassed China to become the world's largest economic power, controlling 24.4% of the world economy, and the world leader in manufacturing, producing 25% of global industrial output. The economic and demographic upsurge was stimulated by Mughal agrarian reforms that intensified agricultural production, and a relatively high degree of urbanisation.

Other Mughal UNESCO World Heritage Sites

The Mughal Empire reached the zenith of its territorial expanse during the reign of Aurangzeb (r. 1658–1707), under whose reign India surpassed Qing China as the world's largest economy. Aurangzeb was less tolerant than his predecessors, reintroducing the jizya tax and destroying several historical temples, while at the same time building more Hindu temples than he destroyed, employing significantly more Hindus in his imperial bureaucracy than his predecessors, and advancing administrators based on ability rather than religion. However, he is often blamed for the erosion of the tolerant syncretic tradition of his predecessors, as well as increasing religious controversy and centralisation. The English East India Company suffered a defeat in the Anglo-Mughal War.

The Mughals suffered several blows due to invasions from Marathas, Rajputs, Jats and Afghans. In 1737, the Maratha general Bajirao of the Maratha Empire invaded and plundered Delhi. Under the general Amir Khan Umrao Al Udat, the Mughal Emperor sent 8,000 troops to drive away the 5,000 Maratha cavalry soldiers. Baji Rao easily routed the novice Mughal general. In 1737, in the final defeat of Mughal Empire, the commander-in-chief of the Mughal Army, Nizam-ul-mulk, was routed at Bhopal by the Maratha army. This essentially brought an end to the Mughal Empire. While Bharatpur State under Jat ruler Suraj Mal, overran the Mughal garrison at Agra and plundered the city. In 1739, Nader Shah, emperor of Iran, defeated the Mughal army at the Battle of Karnal. After this victory, Nader captured and sacked Delhi, carrying away treasures including the Peacock Throne. Ahmad Shah Durrani commenced his own invasions as ruler of the Durrani Empire, eventually sacking Delhi in 1757. Mughal rule was further weakened by constant native Indian resistance; Banda Singh Bahadur led the Sikh Khalsa against Mughal religious oppression; Hindu Rajas of Bengal, Pratapaditya and Raja Sitaram Ray revolted; and Maharaja Chhatrasal, of Bundela Rajputs, fought the Mughals and established the Panna State. The Mughal dynasty was reduced to puppet rulers by 1757. Vadda Ghalughara took place under the Muslim provincial government based at Lahore to wipe out the Sikhs, with 30,000 Sikhs being killed, an offensive that had begun with the Mughals, with the Chhota Ghallughara, and lasted several decades under its Muslim successor states.

Maratha Empire

The Maratha kingdom was founded and consolidated by Chatrapati Shivaji. However, the credit for making the Marathas formidable power nationally goes to Peshwa (chief minister) Bajirao I. Historian K.K. Datta wrote that Bajirao I "may very well be regarded as the second founder of the Maratha Empire".

In the early 18th century, under the Peshwas, the Marathas consolidated and ruled over much of South Asia. The Marathas are credited to a large extent for ending Mughal rule in India. In 1737, the Marathas defeated a Mughal army in their capital, in the Battle of Delhi. The Marathas continued their military campaigns against the Mughals, Nizam, Nawab of Bengal and the Durrani Empire to further extend their boundaries. At its peak, the domain of the Marathas encompassed most of the Indian subcontinent. The Marathas even attempted to capture Delhi and discussed putting Vishwasrao Peshwa on the throne there in place of the Mughal emperor.

The Maratha empire at its peak stretched from Tamil Nadu in the south, to Peshawar (modern-day Khyber Pakhtunkhwa, Pakistan ) in the north, and Bengal in the east. The Northwestern expansion of the Marathas was stopped after the Third Battle of Panipat (1761). However, the Maratha authority in the north was re-established within a decade under Peshwa Madhavrao I.

Under Madhavrao I, the strongest knights were granted semi-autonomy, creating a confederacy of United Maratha states under the Gaekwads of Baroda, the Holkars of Indore and Malwa, the Scindias of Gwalior and Ujjain, the Bhonsales of Nagpur and the Puars of Dhar and Dewas. In 1775, the East India Company intervened in a Peshwa family succession struggle in Pune, which led to the First Anglo-Maratha War, resulting in a Maratha victory. The Marathas remained a major power in India until their defeat in the Second and Third Anglo-Maratha Wars (1805–1818).

Sikh Empire

The Sikh Empire was a political entity that governed the northwestern regions of the Indian subcontinent, based around the Punjab, from 1799 to 1849. It was forged, on the foundations of the Khalsa, under the leadership of Maharaja Ranjit Singh (1780–1839).

Maharaja Ranjit Singh consolidated much of northern India into an empire using his Sikh Khalsa Army, trained in European military techniques and equipped with modern military technologies. Ranjit Singh proved himself to be a master strategist and selected well-qualified generals for his army. He successfully ended the Afghan-Sikh Wars. In stages, he added central Punjab, the provinces of Multan and Kashmir, and the Peshawar Valley to his empire.

At its peak in the 19th century, the empire extended from the Khyber Pass in the west, to Kashmir in the north, to Sindh in the south, running along Sutlej river to Himachal in the east. After the death of Ranjit Singh, the empire weakened, leading to conflict with the British East India Company. The First Anglo-Sikh War and Second Anglo-Sikh War marked the downfall of the Sikh Empire, making it among the last areas of the Indian subcontinent to be conquered by the British.

Other kingdoms

The Kingdom of Mysore in southern India expanded to its greatest extent under Hyder Ali and his son Tipu Sultan in the later half of the 18th century. Under their rule, Mysore fought series of wars against the Marathas and British or their combined forces. The Maratha–Mysore War ended in April 1787, following the finalising of treaty of Gajendragad, in which Tipu Sultan was obligated to pay tribute to the Marathas. Concurrently, the Anglo-Mysore Wars took place, where the Mysoreans used the Mysorean rockets. The Fourth Anglo-Mysore War (1798–1799) saw the death of Tipu. Mysore's alliance with the French was seen as a threat to the British East India Company, and Mysore was attacked from all four sides. The Nizam of Hyderabad and the Marathas launched an invasion from the north. The British won a decisive victory at the Siege of Seringapatam (1799).

Hyderabad was founded by the Qutb Shahi dynasty of Golconda in 1591. Following a brief Mughal rule, Asif Jah, a Mughal official, seized control of Hyderabad and declared himself Nizam-al-Mulk of Hyderabad in 1724. The Nizams lost considerable territory and paid tribute to the Maratha Empire after being routed in multiple battles, such as the Battle of Palkhed. However, the Nizams maintained their sovereignty from 1724 until 1948 through paying tributes to the Marathas, and later, being vassals of the British. Hyderabad State became a princely state in British India in 1798.

The Nawabs of Bengal had become the de facto rulers of Bengal following the decline of Mughal Empire. However, their rule was interrupted by Marathas who carried out six expeditions in Bengal from 1741 to 1748, as a result of which Bengal became a tributary state of Marathas. On 23 June 1757, Siraj ud-Daulah, the last independent Nawab of Bengal was betrayed in the Battle of Plassey by Mir Jafar. He lost to the British, who took over the charge of Bengal in 1757, installed Mir Jafar on the Masnad (throne) and established itself to a political power in Bengal. In 1765 the system of Dual Government was established, in which the Nawabs ruled on behalf of the British and were mere puppets to the British. In 1772 the system was abolished and Bengal was brought under the direct control of the British. In 1793, when the Nizamat (governorship) of the Nawab was also taken away, they remained as mere pensioners of the British East India Company.

In the 18th century, the whole of Rajputana was virtually subdued by the Marathas. The Second Anglo-Maratha War distracted the Marathas from 1807 to 1809, but afterward Maratha domination of Rajputana resumed. In 1817, the British went to war with the Pindaris, raiders who were fled in Maratha territory, which quickly became the Third Anglo-Maratha War, and the British government offered its protection to the Rajput rulers from the Pindaris and the Marathas. By the end of 1818 similar treaties had been executed between the other Rajput states and Britain. The Maratha Sindhia ruler of Gwalior gave up the district of Ajmer-Merwara to the British, and Maratha influence in Rajasthan came to an end. Most of the Rajput princes remained loyal to Britain in the Revolt of 1857, and few political changes were made in Rajputana until Indian independence in 1947. The Rajputana Agency contained more than 20 princely states, most notable being Udaipur State, Jaipur State, Bikaner State and Jodhpur State.

After the fall of the Maratha Empire, many Maratha dynasties and states became vassals in a subsidiary alliance with the British. With the decline of the Sikh Empire, after the First Anglo-Sikh War in 1846, under the terms of the Treaty of Amritsar, the British government sold Kashmir to Maharaja Gulab Singh and the princely state of Jammu and Kashmir, the second-largest princely state in British India, was created by the Dogra dynasty. While in eastern and north-eastern India, the Hindu and Buddhist states of Cooch Behar Kingdom, Twipra Kingdom and Kingdom of Sikkim were annexed by the British and made vassal princely state.

After the fall of the Vijayanagara Empire, Polygar states emerged in Southern India; and managed to weather invasions and flourished until the Polygar Wars, where they were defeated by the British East India Company forces. Around the 18th century, the Kingdom of Nepal was formed by Rajput rulers.

Portuguese exploration

In 1498, a Portuguese fleet under Vasco da Gama discovered a new sea route from Europe to India, which paved the way for direct Indo-European commerce. The Portuguese soon set up trading posts in Velha Goa, Damaon, Dio island, and Bombay. The Portuguese instituted the Goa Inquisition, where new Indian converts were punished for suspected heresy against Christianity and non-Christians were condemned. Goa remained the main Portuguese territory until it was annexed by India in 1961.

Other Europeans

The next to arrive were the Dutch, with their main base in Ceylon. They established ports in Malabar. However, their expansion into India was halted after their defeat in the Battle of Colachel by the Kingdom of Travancore during the Travancore-Dutch War. The Dutch never recovered from the defeat and no longer posed a large colonial threat to India.

The internal conflicts among Indian kingdoms gave opportunities to the European traders to gradually establish political influence and appropriate lands. Following the Dutch, the British — who set up in the west coast port of Surat in 1619 — and the French both established trading outposts in India. Although continental European powers controlled various coastal regions of southern and eastern India during the ensuing century, they eventually lost all their territories in India to the British, with the exception of the French outposts of Pondichéry and Chandernagore, and the Portuguese colonies of Goa, Daman and Diu.

East India Company rule in India

The English East India Company was founded in 1600. It gained a foothold in India with the establishment of a factory in Masulipatnam on the Eastern coast of India in 1611 and a grant of rights by the Mughal emperor Jahangir to establish a factory in Surat in 1612. In 1640, after receiving similar permission from the Vijayanagara ruler farther south, a second factory was established in Madras on the southeastern coast. The islet of Bom Bahia in present-day Mumbai (Bombay) was a Portuguese outpost not far from Surat. It was presented to Charles II of England as dowry in his marriage to Catherine of Braganza. Charles in turn leased Bombay to the Company in 1668. Two decades later, the company established a trade post in the River Ganges delta. During this time other companies established by the Portuguese, Dutch, French, and Danish were similarly expanding in the subcontinent.

The company's victory under Robert Clive in the 1757 Battle of Plassey and another victory in the 1764 Battle of Buxar (in Bihar), consolidated the company's power, and forced emperor Shah Alam II to appoint it the diwan, or revenue collector, of Bengal, Bihar, and Orissa. The company thus became the de facto ruler of large areas of the lower Gangetic plain by 1773. It also proceeded by degrees to expand its dominions around Bombay and Madras. The Anglo-Mysore Wars (1766–1799) and the Anglo-Maratha Wars (1772–1818) left it in control of large areas of India south of the Sutlej River. With the defeat of the Marathas, no native power represented a threat for the company any longer.

The expansion of the company's power chiefly took two forms. The first of these was the outright annexation of Indian states and subsequent direct governance of the underlying regions that collectively came to comprise British India. The annexed regions included the North-Western Provinces (comprising Rohilkhand, Gorakhpur, and the Doab) (1801), Delhi (1803), Assam (Ahom Kingdom 1828), and Sindh (1843). Punjab, North-West Frontier Province, and Kashmir were annexed after the Anglo-Sikh Wars in 1849–1856 (period of tenure of Marquess of Dalhousie Governor General). However, Kashmir was immediately sold under the Treaty of Amritsar (1850) to the Dogra dynasty of Jammu and thereby became a princely state. In 1854, Berar was annexed along with the state of Oudh two years later.

The second form of asserting power involved treaties in which Indian rulers acknowledged the company's hegemony in return for limited internal autonomy. Since the company operated under financial constraints, it had to set up political underpinnings for its rule. The most important such support came from the subsidiary alliances with Indian princes. In the early 19th century, the territories of these princes accounted for two-thirds of India. When an Indian ruler who was able to secure his territory wanted to enter such an alliance, the company welcomed it as an economical method of indirect rule that did not involve the economic costs of direct administration or the political costs of gaining the support of alien subjects.

In return, the company undertook the "defense of these subordinate allies and treated them with traditional respect and marks of honor." Subsidiary alliances created the princely states of the Hindu maharajas and the Muslim nawabs. Prominent among the princely states were Cochin (1791), Jaipur (1794), Travancore (1795), Hyderabad (1798), Mysore (1799), Cis-Sutlej Hill States (1815), Rajputana (1818), Central India Agency (1819), Cutch and Gujarat Gaikwad territories (1819), and Bahawalpur (1833).

Indian indenture system

The Indian indenture system was an ongoing system of indenture, a form of debt bondage, by which 3.5 million Indians were transported to colonies of European powers to provide labour for the (mainly sugar) plantations. It started from the end of slavery in 1833 and continued until 1920. This resulted in the development of a large Indian diaspora that spread from the Caribbean to the Pacific Ocean and the growth of large Indo-Caribbean and Indo-African populations.

Late modern period and contemporary history (1857–1947)

Rebellion of 1857 and its consequences

The Indian rebellion of 1857 was a large-scale rebellion by soldiers employed by the British East India Company in northern and central India against the company's rule. The spark that led to the mutiny was the issue of new gunpowder cartridges for the Enfield rifle, which was insensitive to local religious prohibition. The key mutineer was Mangal Pandey. In addition, the underlying grievances over British taxation, the ethnic gulf between the British officers and their Indian troops and land annexations played a significant role in the rebellion. Within weeks after Pandey's mutiny, dozens of units of the Indian army joined peasant armies in widespread rebellion. The rebel soldiers were later joined by Indian nobility, many of whom had lost titles and domains under the Doctrine of Lapse and felt that the company had interfered with a traditional system of inheritance. Rebel leaders such as Nana Sahib and the Rani of Jhansi belonged to this group.

After the outbreak of the mutiny in Meerut, the rebels very quickly reached Delhi. The rebels had also captured large tracts of the North-Western Provinces and Awadh (Oudh). Most notably, in Awadh, the rebellion took on the attributes of a patriotic revolt against British presence. However, the British East India Company mobilised rapidly with the assistance of friendly Princely states, but it took the British the better part of 1858 to suppress the rebellion. Due to the rebels being poorly equipped and having no outside support or funding, they were brutally subdued.

In the aftermath, all power was transferred from the British East India Company to the British Crown, which began to administer most of India as provinces. The Crown controlled the company's lands directly and had considerable indirect influence over the rest of India, which consisted of the Princely states ruled by local royal families. There were officially 565 princely states in 1947, but only 21 had actual state governments, and only three were large (Mysore, Hyderabad, and Kashmir). They were absorbed into the independent nation in 1947–1948.

British Raj (1858–1947)

After 1857, the colonial government strengthened and expanded its infrastructure via the court system, legal procedures, and statutes. The Indian Penal Code came into being. In education, Thomas Babington Macaulay had made schooling a priority for the Raj in 1835 and succeeded in implementing the use of English for instruction. By 1890, some 60,000 Indians had matriculated. The Indian economy grew at about 1% per year from 1880 to 1920, and the population also grew at 1%. However, from the 1910s, Indian private industry began to grow significantly. India built a modern railway system in the late 19th century which was the fourth largest in the world. Historians have been divided on issues of economic history, with the Nationalist school arguing that India was poorer due to British rule.

In 1905, Lord Curzon split the large province of Bengal into a largely Hindu western half and "Eastern Bengal and Assam", a largely Muslim eastern half. The British goal was said to be efficient administration but the people of Bengal were outraged at the apparent "divide and rule" strategy. It also marked the beginning of the organised anti-colonial movement. When the Liberal Party in Britain came to power in 1906, he was removed. Bengal was reunified in 1911. The new Viceroy Gilbert Minto and the new Secretary of State for India John Morley consulted with Congress leaders on political reforms. The Morley-Minto reforms of 1909 provided for Indian membership of the provincial executive councils as well as the Viceroy's executive council. The Imperial Legislative Council was enlarged from 25 to 60 members and separate communal representation for Muslims was established in a dramatic step towards representative and responsible government. Several socio-religious organisations came into being at that time. Muslims set up the All India Muslim League in 1906 to protect the interests of the aristocratic Muslims. The Hindu Mahasabha sought to represent Hindu interests. The Hindu nationalist Rashtriya Swayamsevak Sangh (RSS) was formed in 1925–1926. Sikhs founded the Shiromani Akali Dal in 1920. However, the largest and oldest political party Indian National Congress, founded in 1885, attempted to keep a distance from the socio-religious movements and identity politics.

Indian Renaissance

The Bengali Renaissance refers to a social reform movement, dominated by Bengali Hindus, in the Bengal region of the Indian subcontinent during the nineteenth and early twentieth centuries, a period of British rule. Historian Nitish Sengupta describes the renaissance as having started with reformer and humanitarian Raja Ram Mohan Roy (1775–1833), and ended with Asia's first Nobel laureate Rabindranath Tagore (1861–1941). This flowering of religious and social reformers, scholars, and writers is described by historian David Kopf as "one of the most creative periods in Indian history."

During this period, Bengal witnessed an intellectual awakening that is in some way similar to the Renaissance. This movement questioned existing orthodoxies, particularly with respect to women, marriage, the dowry system, the caste system, and religion. One of the earliest social movements that emerged during this time was the Young Bengal movement, which espoused rationalism and atheism as the common denominators of civil conduct among upper caste educated Hindus. It played an important role in reawakening Indian minds and intellect across the Indian subcontinent.

Famines

During British East India Company and British Crown rule, India experienced some of deadliest ever recorded famines. These famines, usually resulting from crop failures and often exacerbated by policies of the colonial government, included the Great Famine of 1876–1878 in which 6.1 million to 10.3 million people died, the Great Bengal famine of 1770 where between 1 and 10 million people died, the Indian famine of 1899–1900 in which 1.25 to 10 million people died, and the Bengal famine of 1943 where between 2.1 and 3.8 million people died. The third plague pandemic in the mid-19th century killed 10 million people in India. Despite persistent diseases and famines, the population of the Indian subcontinent, which stood at up to 200 million in 1750, had reached 389 million by 1941.

World War I

During World War I, over 800,000 volunteered for the army, and more than 400,000 volunteered for non-combat roles, compared with the pre-war annual recruitment of about 15,000 men. The Army saw early action on the Western Front at the First Battle of Ypres. After a year of front-line duty, sickness and casualties had reduced the Indian Corps to the point where it had to be withdrawn. Nearly 700,000 Indians fought the Turks in the Mesopotamian campaign. Indian formations were also sent to East Africa, Egypt, and Gallipoli.

The Indian Army and the Imperial Service Troops fought during the Sinai and Palestine Campaign's defence of the Suez Canal in 1915, at Romani in 1916 and to Jerusalem in 1917. Indian units occupied the Jordan Valley and after the German spring offensive they became the major force in the Egyptian Expeditionary Force during the Battle of Megiddo and in the Desert Mounted Corps' advance to Damascus and on to Aleppo. Other divisions remained in India guarding the North-West Frontier and fulfilling internal security obligations.

One million Indian troops served abroad during the war. In total, 74,187 died, and another 67,000 were wounded. The roughly 90,000 soldiers who died fighting in World War I and the Afghan Wars are commemorated by the India Gate.

World War II

British India officially declared war on Nazi Germany in September 1939. The British Raj, as part of the Allied Nations, sent over two and a half million volunteer soldiers to fight under British command against the Axis powers. Additionally, several princely states provided large donations to support the Allied campaign. India also provided the base for American operations in support of China in the China Burma India Theatre.

Indians fought throughout the world, including in the European theatre against Germany, in North Africa against Germany and Italy, against the Italians in East Africa, in the Middle East against the Vichy French, in the South Asian region defending India against the Japanese and fighting the Japanese in Burma. Indians also aided in liberating British colonies such as Singapore and Hong Kong after the Japanese surrender in August 1945. Over 87,000 soldiers from the subcontinent died in World War II.

The Indian National Congress denounced Nazi Germany but would not fight it or anyone else until India was independent. Congress launched the Quit India Movement in August 1942, refusing to co-operate in any way with the government until independence was granted. The government immediately arrested over 60,000 national and local Congress leaders. The Muslim League rejected the Quit India movement and worked closely with the Raj authorities.

Subhas Chandra Bose (also called Netaji) broke with Congress and tried to form a military alliance with Germany or Japan to gain independence. The Germans assisted Bose in the formation of the Indian Legion; however, it was Japan that helped him revamp the Indian National Army (INA), after the First Indian National Army under Mohan Singh was dissolved. The INA fought under Japanese direction, mostly in Burma. Bose also headed the Provisional Government of Free India (or Azad Hind), a government-in-exile based in Singapore.

By 1942, neighbouring Burma was invaded by Japan, which by then had already captured the Indian territory of Andaman and Nicobar Islands. Japan gave nominal control of the islands to the Provisional Government of Free India on 21 October 1943, and in the following March, the Indian National Army with the help of Japan crossed into India and advanced as far as Kohima in Nagaland. This advance on the mainland of the Indian subcontinent reached its farthest point on Indian territory, retreating from the Battle of Kohima in June and from that of Imphal on 3 July 1944.

The region of Bengal in British India suffered a devastating famine during 1940–1943. An estimated 2.1–3 million died from the famine, frequently characterised as "man-made," with most sources asserting that wartime colonial policies exacerbated the crisis.

Indian independence movement (1885–1947)

The numbers of British in India were small, yet they were able to rule 52% of the Indian subcontinent directly and exercise considerable leverage over the princely states that accounted for 48% of the area.

One of the most important events of the 19th century was the rise of Indian nationalism, leading Indians to seek first "self-rule" and later "complete independence". However, historians are divided over the causes of its rise. Probable reasons include a "clash of interests of the Indian people with British interests", "racial discriminations", and "the revelation of India's past".

The first step toward Indian self-rule was the appointment of councillors to advise the British viceroy in 1861 and the first Indian was appointed in 1909. Provincial Councils with Indian members were also set up. The councillors' participation was subsequently widened into legislative councils. The British built a large British Indian Army, with the senior officers all British and many of the troops from small minority groups such as Gurkhas from Nepal and Sikhs. The civil service was increasingly filled with natives at the lower levels, with the British holding the more senior positions.

Bal Gangadhar Tilak, an Indian nationalist leader, declared Swaraj (home rule) as the destiny of the nation. His popular sentence "Swaraj is my birthright, and I shall have it" became the source of inspiration. Tilak was backed by rising public leaders like Bipin Chandra Pal and Lala Lajpat Rai, who held the same point of view, notably they advocated the Swadeshi movement involving the boycott of imported items and the use of Indian-made goods; the triumvirate were popularly known as Lal Bal Pal. In 1907, the Congress was split into two factions: The radicals, led by Tilak, advocated civil agitation and direct revolution to overthrow the British Empire and the abandonment of all things British. The moderates, led by leaders like Dadabhai Naoroji and Gopal Krishna Gokhale, on the other hand, wanted reform within the framework of British rule.

The partition of Bengal in 1905 further increased the revolutionary movement for Indian independence. The disenfranchisement lead some to take violent action.

The British themselves adopted a "carrot and stick" approach in response to renewed nationalist demands. The means of achieving the proposed measure were later enshrined in the Government of India Act 1919, which introduced the principle of a dual mode of administration, or diarchy, in which elected Indian legislators and appointed British officials shared power. In 1919, Colonel Reginald Dyer ordered his troops to fire their weapons on peaceful protestors, including unarmed women and children, resulting in the Jallianwala Bagh massacre; which led to the non-cooperation movement of 1920–1922. The massacre was a decisive episode towards the end of British rule in India.

From 1920 leaders such as Mahatma Gandhi began highly popular mass movements to campaign against the British Raj using largely peaceful methods. The Gandhi-led independence movement opposed the British rule using non-violent methods like non-co-operation, civil disobedience and economic resistance. However, revolutionary activities against the British rule took place throughout the Indian subcontinent and some others adopted a militant approach like the Hindustan Republican Association, that sought to overthrow British rule by armed struggle.

The All India Azad Muslim Conference gathered in Delhi in April 1940 to voice its support for an independent and united India. Its members included several Islamic organisations in India, as well as 1,400 nationalist Muslim delegates. The pro-separatist All-India Muslim League worked to try to silence those nationalist Muslims who stood against the partition of India, often using "intimidation and coercion". The murder of the All India Azad Muslim Conference leader Allah Bakhsh Soomro also made it easier for the pro-separatist All-India Muslim League to demand the creation of a Pakistan.

After World War II (c. 1946–1947)

In January 1946, several mutinies broke out in the armed services, starting with that of RAF servicemen frustrated with their slow repatriation. The mutinies came to a head with mutiny of the Royal Indian Navy in Bombay in February 1946, followed by others in Calcutta, Madras, and Karachi. The mutinies were rapidly suppressed. In early 1946, new elections were called and Congress candidates won in eight of the eleven provinces.

Late in 1946, the Labour government decided to end British rule of India, and in early 1947 it announced its intention of transferring power no later than June 1948 and participating in the formation of an interim government.

Along with the desire for independence, tensions between Hindus and Muslims had also been developing over the years. Muslim League leader Muhammad Ali Jinnah proclaimed 16 August 1946 as Direct Action Day, with the stated goal of highlighting, peacefully, the demand for a Muslim homeland in British India, which resulted in the outbreak of the cycle of violence that would be later called the "Great Calcutta Killing of August 1946". The communal violence spread to Bihar, Noakhali in Bengal, Garhmukteshwar in the United Provinces, and on to Rawalpindi in March 1947 in which Sikhs and Hindus were attacked or driven out by Muslims. Louis Mountbatten became the Viceroy of India in February 1947, arriving in India in March, and oversaw the decolonisation and partition of British India.

Independence and partition (1947–present)

In August 1947, the British Indian Empire was partitioned into the Dominions of India and Pakistan. In particular, the partition of the Punjab and Bengal led to rioting between Hindus, Muslims, and Sikhs in these provinces and spread to other nearby regions, leaving some 500,000 dead. The police and army units were largely ineffective. The British officers were gone, and the units were beginning to tolerate if not actually indulge in violence against their religious enemies. Also, this period saw one of the largest mass migrations anywhere in modern history, with a total of 12 million Hindus, Sikhs and Muslims moving between the newly created nations of India and Pakistan (which gained independence on 15 and 14 August 1947 respectively). In 1971, Bangladesh, formerly East Pakistan and East Bengal, seceded from Pakistan.
