Indira Priyadarshini Gandhi (इंदिरा प्रियदर्शिनी गांधी Indirā Priyadarśinī Gāndhī) (19 November, 1917 - October 31, 1984) was the Prime Minister of India for three consecutive terms from 1966 to 1977 and for a fourth term from 1980 until her assassination in 1984. She was India's first and to date only female prime minister.

Born in the politically influential Nehru dynasty, she grew up in an intensely political atmosphere. Her grandfather, Motilal Nehru, was a prominent Indian nationalist leader. Her father, Jawaharlal Nehru was a pivotal figure in the Indian independence movement and the first Prime Minister of Independent India. Returning to India from Oxford in 1941, she became involved in the Indian Independence movement.

In the 1950s, she served her father unofficially as a personal assistant during his tenure as India's first Prime Minister. After her father's death in 1964, she was appointed as a member of the Rajya Sabha by the President of India and became a member of Lal Bahadur Shastri's cabinet as Minister of Information and Broadcasting.

The then Congress Party President K. Kamaraj was instrumental in making Indira Gandhi the Prime Minister after the sudden demise of Shastri. Gandhi soon showed an ability to win elections and outmaneuver opponents through populism. She introduced more left-wing economic policies and promoted agricultural productivity. A crushing victory in the 1971 war with Pakistan was followed by a period of instability that led her to impose a state of emergency in 1975; she paid for the authoritarian excesses of the period with three years in opposition. Returned to office in 1980, she became increasingly involved in an escalating conflict with separatists in Punjab that eventually led to her assassination by her own bodyguards in 1984.
