Under DMK's pressure, the AIADMK ministry and the Tamil Nadu legislative assembly were dismissed by the Indira Gandhi-led government on grounds of civil disorder due to farmers protests for electricity subsidies.
[7] In the wake of Chief Minister MGR's hospitalization in New York City and subsequent Assassination of Indira Gandhi, newly assumed Prime Minister Rajiv Gandhi felt that his Government required a fresh mandate from the people, and dissolved the Lok Sabha a year before its actual end of term, for fresh general elections.
At the same time, AIADMK recommended dissolution of Tamil Nadu State Assembly a year ahead of end of term, to use the sympathy wave of Congress due to Indira's death and M.G.R's illness.
Congress(I) and AIADMK formed an alliance and contested both general elections to Lok Sabha and Tamil Nadu Assembly in 1984.
Due to its split, the AIADMK suffered heavily in the election, with the Janaki and Jayalalithaa factions winning only 2 and 27 seats, respectively.
In the 2001 assembly election, the AIADMK-led Secular Democratic Progressive Alliance, consisting of the Indian National Congress, the Tamil Maanila Congress (Moopanar) (TMC(M)), the Left Front, and the Pattali Makkal Katchi (PMK), regained power, winning 197 seats to the AIADMK's 132.
Rangasamy, on the other hand, formed the government without consulting the AIADMK and refused to share power with the pre-election alliance partner.
It opted not to join any alliance and contested all seats in the state of Tamil Nadu and the union territory of Puducherry on its own.
In the 2019 Lok Sabha election, AIADMK led by then Tamil Nadu Chief Minister Edappadi K. Palaniswami and Deputy Chief Minister O. Panneerselvam as Coordinators, in alliance with the BJP again, won only one of the 39 Lok Sabha seats from the state and lost to the DMK led Secular Progressive Alliance.
During the period of 2022-23, The AIADMK again undergone many changes like abolition of dual leadership[12] and the election of Edappadi K. Palaniswami as its General Secretary.
