History

Religious demographics in the region known today as Afghanistan have shifted numerous times in history. In ancient and classical periods, Zoroastrianism, Hinduism, followed by Buddhism were the primary religions in the region. Islam gradually became the primary religion in the region after first being introduced in the 7th century A.D., when the Rashidun Caliphate conquered parts of the region.

The religion Zoroastrianism is believed by some to have originated in what is now Afghanistan between 1800 and 800 BCE, as its founder Zoroaster is thought to have lived and died in Balkh while the region at the time was referred to as Ariana. Ancient Eastern Iranian languages may have been spoken in the region around the time of the rise of Zoroastrianism. By the middle of the 6th century BCE, the Achaemenids overthrew the Medes and incorporated Arachosia, Aria, and Bactria within its eastern boundaries. An inscription on the tombstone of Darius I of Persia mentions the Kabul Valley in a list of the 29 countries that he had conquered.

Before the arrival of Islam, Southern Afghanistan used to be a stronghold of Zoroastrianism. There were close relations between Persia and Arachosia concerning the Zoroastrian faith. It is believed that the Avesta had arrived in Persia through Arachosia. Thus the region is also considered as a "second fatherland for Zoroastrianism".

Mainly concentrated in eastern and southern regions of present-day Afghanistan, early Indo-Aryan inhabitants (between 2000 and 1500 BCE) were adherents of Hinduism. Notable among these inhabitant groups were the Gandharis and Kambojas, while the Pashayi and Nuristanis are contemporary examples of these Indo-Aryan Vedic people. With a component of Vedic ancestors from the Pakthas, Pashtuns, the majority eastern Iranian ethnic group in Afghanistan, also widely practiced Hinduism and Buddhism.

"The Pakthas, Bhalanases, Vishanins, Alinas, and Sivas were the five frontier tribes. The Pakthas lived in the hills from which the Kruma originates. Zimmer locates them in present-day eastern Afghanistan, identifying them with the modern Pakthun."

Following Alexander the Great's conquest and occupation in the 4th century BC, the successor-state Seleucid Empire controlled the area until 305 BC when they gave much of it to the Indian Maurya Empire as part of an alliance treaty. The Mauryans brought Buddhism from India and controlled parts of southern and eastern Afghanistan until about 185 BC when they were overthrown.

In the 7th century, the Umayyad Arab Muslims entered into the area now known as Afghanistan after decisively defeating the Sassanians in the Battle of Nihawand (642 AD). Following this colossal defeat, the last Sassanid Emperor, Yazdegerd III, became a hunted fugitive and fled eastward deep into Central Asia. In pursuing Yazdegerd, the Arabs chose to enter the area from north-eastern Iran and thereafter into Herat, where they stationed a large portion of their army before advancing toward the rest of Afghanistan. The Arabs exerted considerable efforts toward propagating Islam amongst the locals.

A large number of the inhabitants of the region of northern Afghanistan accepted Islam through Umayyad missionary efforts, particularly under the reigns of Hisham ibn Abd al-Malik (caliph from 724 to 743) and Umar ibn AbdulAziz (caliph from 717 to 720). During the reign of Al-Mu'tasim Islam was generally practiced amongst most inhabitants of the region and finally under Ya'qub-i Laith Saffari, Islam was by far, the predominant religion of Kabul along with other major cities of Afghanistan. Later, the Samanids propagated Islam deep into the heart of Central Asia, as the first complete translation of the Qur'an into Persian occurred in the 9th century. Since the 9th century, Islam has dominated the country's religious landscape. Islamic leaders have entered the political sphere at various times of crisis, but rarely exercised secular authority for long. Remnants of the Hindu Shahi dynasty in Afghanistan's eastern borders were expelled by Mahmud of Ghazni during 998 and 1030.

Until the 1890s, the country's Nuristan region was known as Kafiristan (land of the kafirs or "infidels") because of its inhabitants: the Nuristani, an ethnically distinctive people who practiced Animism and ancient Hinduism.

By the 20th century, Islam made up as much as 99 percent of the population. The country's religious minorities such as Hindus and Jews did, however, enjoy "complete religious freedom" as of the early 1970s.

The 1979 Soviet invasion in support of a communist government triggered a major intervention of religion into Afghan political conflict. The Democratic Republic of Afghanistan (1980–1987) was a secular state; Islam united the multi-ethnic political opposition. The Soviet-backed Marxist-style regime and the People's Democratic Party of Afghanistan (PDPA) moved to reduce the influence of Islam. The PDPA imprisoned, tortured and murdered many members of the religious establishment. After National Reconciliation talks in 1987, Islam became once again the state religion and the country removed the word "Democratic" from its official name. From 1987-1992, the country's official name was the Republic of Afghanistan. The Sikh, Hindu, Christian, and Zoroastrian minorities have declined since; in the 1970s, it is estimated the country had around 500,000 Sikhs and 200,000 Hindus, while perhaps 7–10,000 remained in 2017.

The Taliban won the Afghan Civil War in the 1990s and established the Islamic Emirate of Afghanistan (1996–2001), an autocratic Islamic theocracy that imposed the Taliban's extreme version of Islam on the parts of the country it controlled. After the overthrow of the Taliban in 2001, a new Islamic Republic was established in 2004 that combined state-sponsored Islam with Western democracy, the Islamic Republic of Afghanistan. With the fall of the Republic in 2021 and the return of the Taliban, it remains to be seen how the new Taliban government treats the matter; their harsh suppression of journalism and foreigners have made getting reliable reports on the religious situation in Afghanistan difficult.

For Afghans, Islam represents a potentially unifying symbolic system which offsets the divisiveness that frequently rises from the existence of a deep pride in tribal loyalties and an abounding sense of personal and family honor found in multitribal and multiethnic societies such as Afghanistan. Mosques serve not only as places of worship, but for a multitude of functions, including shelter for guests, places to meet and converse, the focus of social religious festivities and schools. Almost every Afghan has at one time during his youth studied at a mosque school; for some this is the only formal education they receive.
