On August 14-15, 1947, British rule in India ended with the creation of two independent dominions: India and Pakistan. The Indian Independence Act, passed by the British Parliament on July 18, 1947, authorized the partition. British lawyer Cyril Radcliffe, who had never visited India, chaired the boundary commissions that drew the borders dividing Punjab and Bengal. The boundary was published on August 17, two days after independence. An estimated 15 million people crossed the new borders, and between one and two million died in communal violence during the migrations.
