Prime Minister Nehru governed India until his death in 1964. He was succeeded by Lal Bahadur Shastri, who also died in office. In 1966, power passed to Nehru's daughter, Indira Gandhi, Prime Minister from 1966 to 1977. In 1975, beset with deepening political and economic problems, Mrs. Gandhi declared a state of emergency and suspended many civil liberties. Seeking a mandate at the polls for her policies, she called for elections in 1977, only to be defeated by Moraji Desai, who headed the Janata Party, an amalgam of five opposition parties.

In 1979, Desai's Government crumbled. Charan Singh formed an interim government, which was followed by Mrs. Gandhi's return to power in January 1980. On October 31, 1984, Mrs. Gandhi was assassinated, and her son, Rajiv, was chosen by the Congress (I)--for "Indira"--Party to take her place. His government was brought down in 1989 by allegations of corruption and was followed by V.P. Singh and then Chandra Shekhar.
