Serving until his death in May 1964, Nehru remains India's longest - serving prime minister . He was succeeded by fellow Congressman Lal Bahadur Shastri, whose 19 - month term also ended in death . Indira Gandhi, Nehru's daughter, succeeded Shastri in 1966 to become the country's first woman premier . Eleven years later, she was voted out of power in favour of the Janata Party, whose leader Morarji Desai became the first non-Congress prime minister . After he resigned in 1979, his former deputy Charan Singh briefly held office until Indira Gandhi was voted back six months later . Indira Gandhi's second stint as Prime Minister ended five years later on the morning of 31 October 1984, when she was gunned down by her own bodyguards .
