The daughter of Jawaharlal Nehru, she had already served as President of the Indian National Congress (1959–60) and Minister of Information (1964) when she succeeded Lal Bahadur Shastri (1904–66) as Prime Minister. In her first term of office she sought to establish a secular state and to lead India out of poverty. However, in 1975 she introduced an unpopular state of emergency to deal with growing political unrest, and the Congress Party lost the 1977 election. Mrs Gandhi lost her seat and was unsuccessfully tried for corruption. Having formed a breakaway group from the Congress Party—known as the Indian National Congress (I)—in 1978, she was elected Prime Minister again in 1980. Her second period of office was marked by prolonged religious disturbance, during which she alienated many Sikhs by allowing troops to storm the Golden Temple at Amritsar; she was assassinated by her own Sikh bodyguards.
