Rajiv Ratna Gandhi /ˈrɑːdʒiːv ˈɡɑːndiː/ ( pronunciation (help·info); 20 August 1944 – 21 May 1991) was the sixth Prime Minister of India (1984–1989). He took office after his mother's assassination on 31 October 1984; he himself was assassinated on 21 May 1991. He became the youngest Prime Minister of India when he took office at the age of 40.

Rajiv Gandhi was the eldest son of Indira and Feroze Gandhi. He went to study at Trinity College, Cambridge, and later at Imperial College London, but did not complete a degree at either. At Cambridge he met the Italian-born Antonia Albina Maino, then a waitress in a restaurant, whom he later married. After dropping out of university, he became a professional pilot for Indian Airlines. He remained aloof from politics, despite his family's political prominence. It was only following the death of his younger brother Sanjay Gandhi in 1980 that Rajiv entered politics. Following the assassination of his mother in 1984 after Operation Blue Star, the Indian National Congress party leaders nominated him to be Prime Minister.

Indira Priyadarshini Gandhi (Hindi: इंदिरा प्रियदर्शिनी गांधी Indirā Priyadarśinī Gāndhī  listen (help·info), née Nehru; 19 November 1917 – 31 October 1984) was an Indian politician who served as the third Prime Minister of India for three consecutive terms (1966–77) and a fourth term (1980–84). Gandhi was the second female head of government in the world after Sirimavo Bandaranaike of Sri Lanka, and she remains as the world's second longest serving female Prime Minister as of 2012. She was the first woman to become prime minister in India.

Gandhi was the only child of Jawaharlal Nehru, the first prime minister of independent India. She adhered to the quasi-socialist policies of industrial development that had been begun by her father. Gandhi established closer relations with the Soviet Union, depending on that nation for support in India’s long-standing conflict with Pakistan. She was also the only Indian Prime Minister to have declared a state of emergency in order to 'rule by decree' and the only Indian Prime Minister to have been imprisoned after holding that office. She was assassinated by her Sikh bodyguards in retaliation for ordering Operation Blue Star.
