India-Pakistan War of 1971

The Indo-Pakistani war of 1971 began on December 3, 1971, when Pakistan launched a preemptive aerial strike on eight Indian air stations, prompting India to declare war on Pakistan and enter the conflict in support of Bengali nationalist forces. The war ended on December 16, 1971, with the Eastern Command of the Pakistan military signing an instrument of surrender, marking the formation of East Pakistan as the new nation of Bangladesh. The war resulted in the deaths of between 300,000 and 3,000,000 civilians in Bangladesh, and the rape of between 200,000 and 400,000 Bangladeshi women and girls.learn more on wikipedia
