More than 100 million soldiers caused the deaths of 60 to 80 million people, civilians and military, the equivalent of 2.5% of the world population at that time. The war finally ended in Europe after the Soviet Union took control of Berlin and the unconditional surrender of the Germans on May 8, 1945.
