As prime minister, Gandhi was known for her political intransigency and unprecedented centralisation of power. She went to war with Pakistan in support of the independence movement and war of independence in East Pakistan, which resulted in an Indian victory and the creation of Bangladesh, as well as increasing India's influence to the point where it became the sole regional power of South Asia. Citing separatist tendencies, and in response to a call for revolution, Gandhi instituted a state of emergency from 1975 to 1977 where basic civil liberties were suspended and the press was censored. Widespread atrocities were carried out during the emergency. In 1980, she returned to power after free and fair elections. After Gandhi ordered military action in the Golden Temple in Operation Blue Star, her own bodyguards and Sikh nationalists assassinated her on 31 October 1984.
