World War II (WWII), also called the Second World War, was a global war. It took place from 1939â1945. Most of the world's countries, including all the great powers, fought as part of two military alliances: the Allies and the Axis. The war was fought as a total war, meaning all resources a country had were used in the war, even those that didn't belong to the army, such as factories.
