The assembly was elected in the general election of February 1967 and consisted of 234 members including 42 members representing
scheduled castes, two members representing
scheduled tribes and one nominated member. On 18 July 1967, the assembly unanimously adopted a resolution to change the name of Madras State to
Tamil Nadu. This was achieved through the
Madras State (Alteration of Name) Act, 1968 (Central Act 53 of 1968) which was passed by the
Parliament of India and came into force on 14 January 1969, with the assembly being renamed the
Tamil Nadu Legislative Assembly. This assembly marked the most dramatic change in Madras State politics with the first state-government by the DMK party. Since this assembly the previously dominant
Indian National Congress has never returned to power in the state. In addition the
three-language formula was scrapped and replaced by a "two-language" former in which "
Hindi was eliminated from the curriculum, only English and
Tamil were to be taught". Other measures included the sale of rice at a fixed price in the suburbs of
Chennai and the sponsoring of research into the Tamil poem
Tirukkuṛaḷ at Madras State universities. == Annadurai's Cabinet ==
