World War II, Explained [AP Euro Review—Unit 8 Topic 8]

Summary

World War II unfolded in two major theaters: the Pacific and the European. In the Pacific, Japan's aggressive expansion led to conflicts with China and eventually the United States, culminating in the attack on Pearl Harbor. In Europe, Hitler's blitzkrieg tactics initially overwhelmed countries before Britain, the Soviet Union, and the U.S. turned the tide. Key battles, including D-Day and the Battle of Midway, marked turning points. The war ended with Germany's surrender in 1945 and Japan's after the U.S. dropped atomic bombs on Hiroshima and Nagasaki. The war introduced devastating new technologies, particularly nuclear weapons, altering global politics forever.
