Why did the partition of british India cause a refugee crisis?

The partition of British India in 1947 led to the creation of two independent states, India and Pakistan, based on religious lines, with India being predominantly Hindu and Pakistan predominantly Muslim. This division triggered mass migrations, as millions of Hindus and Sikhs moved to India while Muslims relocated to Pakistan, often facing violence and persecution during their journeys. The sudden and chaotic nature of the partition resulted in widespread displacement, creating one of the largest refugee crises in history, as people sought safety and belonging in their new nations. The aftermath left deep scars, with many families separated and communities fractured.
