On August 15, 1947, British India was partitioned into two independent nations: India and Pakistan. The partition led to one of the largest mass migrations in history, with millions of people displaced along religious lines. The event sparked violent communal riots that resulted in the deaths of an estimated 1 million people. The division of India and Pakistan has led to ongoing tensions and conflicts between the two countries. The legacy of partition continues to shape South Asian geopolitics to this day.
