The party eventually merged with the All India Anna Dravida Munnetra Kazhagam (AIADMK) led by M. G. Ramachandran (MGR) in 1977.
The film star and party leader M. G. Ramachandran was expelled from the DMK in 1972 following his differences with Karunanidhi and formed the Anna Dravida Munnetra Kazhagam.
After Dr. Ambedkar, nobody has taken the cudgels in real earnest......We will form a new party, sit on the opposition benches, and fight for the rights of Schedules Castes.
In April 1977, V. R. Nedunchezhiyan the Minister for Education in the DMK cabinet left the party with some other leaders like K. Rajaram, S. Madhavan and P. U. Shanmugam and formed the "Makkal Dravida Munnetra Kazhagam".
However, the Makkal DMK merged with Anna Dravida Munnetra Kazhagam in September 1977 after the ADMK came to power winning the 1977 election.
