The partition of India on August 14-15, 1947 divided the country into the dominion of Pakistan and the union of India, driven by religious tensions and political disputes. The British East India Company's rule, lasting over 300 years, ended with increasing nationalist movements culminating in calls for separation, particularly by the Muslim League. The partition resulted in severe communal violence, mass displacements of over 15 million refugees, and enduring conflicts between India and Pakistan, affecting regional stability for decades.
