The document summarizes the creation of Bangladesh from East Pakistan. It describes the vast differences between East and West Pakistan, the political tensions that arose after the Awami League won elections in 1970 but was denied governing power by the West Pakistani military ruler. This led to riots in East Pakistan and a deadly crackdown by the Pakistani army that killed an estimated 1 million Bengalis over nine months and displaced millions more to India. Ultimately, India intervened on behalf of East Pakistan, helping them gain independence as Bangladesh in 1971.
