Politics of Tamil Nadu

Dravidian parties have dominated state politics since 1967.One of the earliest regional parties was the South Indian Welfare Association, which was founded in 1916. It came to be known as the Justice Party after the name of its English-language daily, "Justice".E.V. Ramasami, popularly known as "Periyar", renamed the party Dravidar Kazhagam in 1944. DK was a non-political party which demanded the establishment of an independent state called Dravida Nadu. However, due to the differences between its two leaders Periyar and C.N. Annadurai, the party was split. Annadurai left the party to form the Dravida Munnetra Kazhagam. The DMK decided to enter into politics in 1956.

In the 19th century, Western scholars proposed that Dravidian languages that dominates the south of India formed a different linguistic group to that of Indo-Aryan languages that are predominant in the north of the country. They also classified Indians into distinct Aryan and Dravidian races, it was supposed that the generally darker-skinned Dravidians constituted a distinct race. This concept has affected thinking in India about racial and regional differences and had an impact on aspects of Tamil nationalism, which has appropriated the claim that Dravidians are the earliest inhabitants of India, and the Aryan population were oppresive interlopers from whom Dravidians should liberate themselves. History has shown that Dravidian linguistic family predates Indo-aryan linguistic family in India, however both language groups have been influenced by the other during the course of three millennia.Re-organisation of Indian states according to linguistic and ethnic basis has moderated Tamil nationalism, especially the demand for separation from the Indian Union. The Anti-Hindi agitations in mid-1960s made the DMK more popular and more powerful political force in the state. The DMK routed the Congress Party in the 1967 elections and took control of the state government, ending Congress's stronghold in Tamil Nadu. C.N. Annadurai became the DMK's first Chief Minister, and Muthuvel Karunanidhi took over as Chief Minister and party leader after Annadurai's death in 1969.Karunanidhi's leadership was soon challenged by M.G. Ramachandran, popularly known as MGR. In 1972, he split from DMK and formed the All India Anna Dravida Munnetra Kazhagam (AIADMK). He was the Chief Minister of the state from 1977 until his death in 1987. After the death of MGR, the party split again into two factions, one led by Janaki Ramachandran, wife of MGR, and the other led by J. Jayalalithaa. After the defeat of AIADMK in 1989 assembly polls, both factions were merged and Jayalalithaa took control of the party. She was elected as the General Secretary of the unified AIADMK. There have been splits in both the DMK and the AIADMK, but since 1967 one of those two parties has held power in the state. In the State Elections post- m.g. ramachandran's death, neither of the two parties could come back to power in consecutive assembly elections. govt formed by : 89-dmk, 91-aiadmk, 96-dmk, 2001-aiadmk & 2006-dmk
