Madrid was one of the most heavily affected cities of Spain in the Civil War (1936–1939). The city was a stronghold of the Republicans from July 1936. Its western suburbs were the scene of an all-out battle in November 1936 and it was during the Civil War that Madrid became the first European city to be bombed by airplanes (Japan was the first to bomb civilians in world history, at Shanghai in 1932) specifically targeting civilians in the history of warfare.
