Why did millions of Hindus, Muslims, and Sikhs flee their homes during the 1947 partition?

The 1947 partition of British India triggered a massive, forced migration of approximately 15 million people, driven by the hasty and chaotic division of the region into the independent nations of India and Pakistan.12

The primary causes of this exodus included:

• Hasty Border Demarcation: The Boundary Commission drew new borders that cut through villages, towns, and fields. Because these borders were not announced until two days after the end of British rule, many people were caught in the middle of the transition without understanding the implications until violence erupted.13
• Communal Violence: The uncertainty surrounding the new borders led to immediate, widespread communal massacres. Communities often attempted to secure territory by driving out or killing members of other religious groups, forcing millions to flee to what they perceived as "shelter" on the other side of the border.12
• Fear and Displacement: Sikhs in western Punjab feared persecution under potential Muslim rule, leading nearly the entire community to flee to India. Similarly, millions of Hindus and Muslims sought safety in regions where their own religion was in the majority.134
