This document provides historical context about the liberation war in Bangladesh and the discrimination faced by Bangladeshis under Pakistani rule from 1947 to 1971. It summarizes the political, economic, and cultural domination by West Pakistan over East Pakistan (present-day Bangladesh) which led to the Bengali calls for independence and ultimately the liberation war. Key events discussed include the language conflict, disparities in development funding and civil service representation, the 1970 elections and crackdown in 1971, and the final liberation of Bangladesh in December 1971 after the Pakistani military surrendered.
