Rajiv Gandhi (; 20 August 1944 – 21 May 1991) was an Indian politician who served as the sixth prime minister of India from 1984 to 1989. He took office after the 1984 assassination of his mother, then Prime Minister Indira Gandhi, to become the youngest Indian Prime minister at the age of 40. Gandhi was from the politically powerful Nehru–Gandhi family, which had been associated with the Indian National Congress party. For much of his childhood, his maternal grandfather Jawaharlal Nehru was prime minister. Gandhi attended college at the University of Cambridge in the United Kingdom. He returned to India in 1966 and became a professional pilot for the state-owned Indian Airlines. In 1968, he married Sonia Gandhi; the couple settled in Delhi to a domestic life with their children Rahul Gandhi and Priyanka Gandhi Vadra. For much of the 1970s, his mother Indira Gandhi was prime minister and his brother Sanjay Gandhi an MP; despite this, Rajiv Gandhi remained apolitical. After Sanjay's death in a plane crash in 1980, Gandhi reluctantly entered politics at the behest of Indira. The following year he won his brother's Parliamentary seat of Amethi and became a member of the Lok Sabha—the lower house of India's Parliament. As part of his political grooming, Rajiv was made general secretary of the Congress party and given significant responsibility in organising the 1982 Asian Games. On the morning of 31 October 1984, his mother (Prime Minister Indira Gandhi) was assassinated by her two Sikh bodyguards Satwant Singh and Beant Singh in the aftermath of Operation Blue Star, an Indian military action to remove Sikh separatist activists from the Golden temple of the Harmandir Sahib. Later that day, Gandhi was appointed prime minister. His leadership was tested over the next few days as organised mobs of Congress supporters rioted against the Sikh community, resulting in anti-Sikh massacres in Delhi. Sources estimate the number of Sikh deaths at about 8,000–17,000. That December, Congress party won the largest Lok Sabha majority to date, 411 seats out of 542. Rajiv Gandhi's period in office was mired in controversies; perhaps the greatest crises were the Bhopal disaster, Bofors scandal and Mohd. Ahmed Khan v. Shah Bano Begum. Soon after installing Gul Shah as Chief Minister in Jammu and Kashmir, the 1986 Kashmir Riots erupted. In 1988, he reversed the coup in Maldives, antagonising militant Tamil groups such as PLOTE, intervening and
