1939-1945 conflict

The 1939-1945 conflict refers to World War II, a global war involving many nations. It started when Germany, led by Adolf Hitler, invaded Poland in 1939. The conflict pitted the Allies—primarily the United States, Britain, the Soviet Union, and China—against the Axis powers, mainly Germany, Italy, and Japan. The war saw significant events like the Holocaust, widespread battles, and the use of atomic bombs. It ended with the unconditional surrender of Germany in May 1945 and Japan in August 1945, reshaping international relations and leading to the establishment of the United Nations and the Cold War.
