Background
By the 1940s Britain was preparing to leave India. Political leaders, including those of the Indian National Congress and the All-India Muslim League, could not agree on a single constitutional plan. The Muslim League's Lahore Resolution of March 1940 called for autonomous Muslim-majority areas, and the demand for Pakistan grew.
The 1947 decision
In June 1947 the British government announced a plan for partition. The Indian Independence Act 1947 created two dominions. Pakistan became independent on 14 August 1947 and India on 15 August 1947.
Drawing the borders
A boundary commission led by Cyril Radcliffe divided Punjab and Bengal. The boundary awards were published on 17 August, after independence, which caused great uncertainty for millions of people living near the new lines.
Migration and violence
An estimated 10 to 20 million people crossed the new borders. Violence broke out, especially in Punjab. Estimates of deaths vary widely, from about two hundred thousand to as many as two million, and historians still debate the exact figure.
Why it still matters
Partition shaped the borders, politics and family histories of South Asia. Many people still carry memories of that time, and its effects are visible in the relations of Pakistan and India today.
