Chief Minister of Tamil Nadu

Since 1950, Tamil Nadu has had 14 chief ministers. The first four chief ministers belonged to the Indian National Congress, of which K. Kamaraj held the post for the longest, for more than nine years. With the rise of Dravidian parties in the state, C. N. Annadurai of the Dravida Munnetra Kazhagam (DMK) became the first non-Congress chief minister in 1969. Annadurai was from the Tamil film industry, and since his tenure, a significant number of the state's chief ministers have hailed from the industry.

M. Karunanidhi of the DMK succeeded Annadurai, and was the longest-serving chief minister, holding the office for nearly nineteen years across five tenures. M. G. Ramachandran of the All India Anna Dravida Munnetra Kazhagam (AIADMK) took office in 1977 and served for nearly a decade across three terms. In 1988, V. N. Janaki Ramachandran of the AIADMK became the first woman to hold the position of the state's chief minister. J. Jayalalithaa of the AIADMK became the youngest Chief Minister of Tamil Nadu at the age of 43 in 1991, and had the second longest tenure, holding the office for more than fourteen years across multiple terms.

There have been four instances of President's rule in Tamil Nadu, most recently in 1991. C. Joseph Vijay of the Tamilaga Vettri Kazhagam is the incumbent Chief Minister since 10 May 2026.

List

The Madras Presidency, based at Fort St. George, was a presidency of India that was established in 1652 by the English East India Company to be the headquarters of the English settlements on the Coromandel Coast.

The territory under the presidency consisted of the village of Madrasapattinam and its surrounding regions. After a series of wars including the Anglo-French wars, Anglo-Mysore wars, and Polygar wars, and the consequent alliance with the Nawab of Arcot, it was expanded to cover the region from the Northern Circars to Cape Comorin, and included present-day Tamil Nadu, the Malabar region of North Kerala, the coastal and Rayalaseema regions of Andhra Pradesh, and the Bellary, Dakshina Kannada, and Udupi districts of Karnataka.

The Indian Councils Act 1861 set up the Madras Legislative Council as an advisory body, without powers, through which the colonial administration obtained advice and assistance from able and willing Indian leaders. However, the members were appointed and not elected by the public. With the enactment of the Government of India Act 1919, the first elected legislature was formed in 1920 after the general elections. The term of the legislative council was three years. It had 132 members, of whom 34 were nominated by the governor and the rest were elected.

As per the Government of India Act 1935, a bicameral legislature was set up with a legislative assembly consisting of 215 members and a legislative council having 56 members. The first legislative assembly under this act was constituted in July 1937. The legislative council was a permanent body, with a third of its members retiring every three years and having the power to decide on bills passed by the assembly.

In 1939, the Governor-General of India declared India's entry into World War II without consulting the Imperial Legislative Council. The Indian National Congress protested by asking all its elected representatives to resign from governments. It was reconstituted after new provincial elections were conducted in 1946. The governance structure also evolved from a modest secretariat with a single secretary for the public department in 1670 to six departments overseen by a chief secretary by 1920.

Development after independence

Madras State, the precursor to the present-day state of Tamil Nadu, was created after India became a republic on 26 January 1950. It consisted of present-day Tamil Nadu and parts of present-day Andhra Pradesh, Karnataka, and Kerala. The first legislature of the Madras State to be elected on the basis of universal suffrage was constituted on 1 March 1952, after the general elections held in January 1952.

The state was split up along linguistic lines in 1953, carving out Andhra State. Under the States Reorganisation Act, 1956, the states of Kerala and Mysore State were carved out of Madras State. Under the Andhra Pradesh and Madras Alteration of Boundaries Act, 1959, with effect from 1 April 1960, Tiruttani taluk and Pallipattu sub-taluk of Chittoor district of Andhra Pradesh were transferred to Madras in exchange for territories from the Chingelput and Salem districts.

Change in nomenclature

During the term of the fourth assembly on 18 July 1967, the house unanimously adopted and recommended that steps be taken by the state government to secure the necessary amendment to the Constitution of India to change the name of Madras State to Tamil Nadu. Accordingly, the Madras State (Alteration of Name) Act, 1968 (Central Act 53 of 1968) was passed by the Parliament of India and came into force on 14 January 1969. Consequently, the nomenclature "Madras Legislative Assembly" was changed to "Tamil Nadu Legislative Assembly". From 1967 onwards, the strength of the assembly continued to remain at 234 plus a nominated member.

From 1952 to 1986, the state had a parliamentary system of government with two democratically elected houses, the Legislative Assembly and the Legislative Council. On 14 May 1986, the state government passed a resolution to abolish the legislative council in the state, which was then moved and adopted by the house. On 1 November 1986, Tamil Nadu became a state with a unicameral legislature, and since then, several times, the state government has taken steps to reconstitute the legislative council, but they have failed for so long. The Tamil Nadu Legislative Council has not been constituted in the state to date.
