The All India Anna Dravida Munnetra Kazhagam (transl. All India Anna Dravidian Progressive Federation; abbr. AIADMK) is an Indian regional political party with great influence in the state of Tamil Nadu and the union territory of Puducherry. It is a Dravidian party founded by the former chief minister of Tamil Nadu M. G. Ramachandran (M.G.R.) at Madurai on 17 October 1972 as a breakaway faction from the Dravida Munnetra Kazhagam after M. Karunanidhi expelled him from the party for demanding an account as the party treasurer. The party is adhering to the policy of socialism and secularism based on the principles of C. N. Annadurai (Anna) collectively coined as Annaism by M.G.R. The party has won a seven-time majority in the Tamil Nadu Legislative Assembly and has emerged as the most successful political outfit in the state's history. It is currently the main opposition party in the Tamil Nadu Legislative Assembly and part of the India-ruling National Democratic Alliance. From 9 February 1989 to 5 December 2016, the AIADMK was led by the former chief minister of Tamil Nadu J. Jayalalithaa (Amma) as general secretary of the party. She was admired as the Mother of the party by her cadre and was highly popular among the Tamil populace until her death in 2016. From 21 August 2017 to 23 June 2022, the party was led under the dual leadership of the former chief ministers of Tamil Nadu O. Panneerselvam and Edappadi K. Palaniswami as coordinator and joint coordinator respectively. From 11 July 2022, the AIADMK is led by the former chief minister of Tamil Nadu Edappadi K. Palaniswami (E.P.S.) as general secretary of the party. The headquarters of the party is called Puratchi Thalaivar M.G.R. Maaligai, which is located at Avvai Shanmugam Salai, Royapettah, Chennai. The building was donated to the party in 1986 by M.G.R.'s wife V. N. Janaki Ramachandran, former chief minister of Tamil Nadu. From Wikipedia
