In short
In 1971, East Pakistan—a territorially separated region of Pakistan inhabited by Bengali Muslims—launched an armed uprising against West Pakistan's military government. The brutal crackdown by Pakistani forces and the subsequent Indian military intervention led to East Pakistan's independence as Bangladesh in December 1971, killing hundreds of thousands and displacing millions.
How it unfolded.
The five-minute version
What actually happened.
Bangladesh and Pakistan are both South Asian Muslim-majority countries. Following the end of British rule in India, the two countries formed a single state for 24 years. The Bangladesh Liberation War in 1971 resulted in the secession of East Pakistan as the People's Republic of Bangladesh. Pakistan recognized Bangladesh in 1974 during the Islamic Summit in Lahore, however relations between the two countries still remained relatively tense until the 2024 July Revolution in Bangladesh which resulted in the overthrow of Sheikh Hasina and the establishment of a new administration in Dhaka that sought to normalize ties with Pakistan, moving away from decades of strained relations rooted in the events of the 1971 Liberation War.
