1984 Tamil Nadu Legislative Assembly election

The 1984 Tamil Nadu Legislative Assembly election was held on January 2, 1985, to elect members to the 12th Legislative Assembly of Tamil Nadu, India. This election was significant as it followed the assassination of former Prime Minister Indira Gandhi, which had a profound impact on the political landscape. The Indian National Congress (INC), under the leadership of Chief Minister M. Karunanidhi of the Dravida Munnetra Kazhagam (DMK), faced a formidable challenge from the All India Anna Dravida Munnetra Kazhagam (AIADMK), led by J. Jayalalithaa. The election saw a high voter turnout and intense campaigning, ultimately resulting in a decisive victory for the DMK-led alliance, consolidating its power within the state's political framework. The assembly consisted of 234 seats, with the DMK securing a substantial majority.
