The document summarizes the Language Movement in Bangladesh that started in 1947 when the central government of Pakistan declared Urdu as the sole official language, despite Bengali being the dominant language. This led to widespread protests from intellectuals and the people of East Pakistan. On February 21, 1952, police opened fire on protesting students at Dhaka University, killing several students who had been advocating for the recognition of Bengali. This event galvanized the movement and February 21st is now commemorated annually in Bangladesh in remembrance of those who died. The movement highlighted cultural and linguistic grievances in East Pakistan and helped lay the foundation for the country's liberation war in 1971.
