What happened

On August 6, 1945, the American B-29 Enola Gay dropped the uranium bomb 'Little Boy' on Hiroshima; three days later, on August 9, Bockscar dropped the plutonium bomb 'Fat Man' on Nagasaki. Each bomb destroyed most of its city and killed tens of thousands of people instantly, with many more dying later from injuries and radiation.

Why it matters

The only wartime use of nuclear weapons, the bombings preceded Japan's surrender within days and opened the atomic age.
