What happened
Triggered by Pakistan's genocidal crackdown in East Pakistan and the refugee crisis, India invaded on December 3, 1971. The war lasted just 13 days. Indian forces, numbering over 300,000, defeated a smaller Pakistani garrison of 90,000 in East Pakistan. Naval and air superiority, combined with superior logistics and local Bengali support, ensured India's victory. Pakistan's Air Force lost over 100 aircraft; its navy was crippled. By December 16, Pakistani forces surrendered, and East Pakistan became the independent nation of Bangladesh. The war killed about 10,000 combatants but indirectly contributed to millions of deaths through disease and starvation during the preceding genocide.
Why it mattered
India's decisive victory established it as South Asia's dominant power. Pakistan lost half its territory and population, traumatizing the nation. The war created a new nation-state, Bangladesh, establishing the principle of secession when minorities faced genocide. The conflict altered Cold War alignments: the U.S. tilted toward Pakistan, while the USSR supported India, deepening bipolar tensions in Asia.
