What had happened for the first 9 months of ww2?

World War II (WWII) was a long and bloody war that lasted about six years. Officially beginning on September 1, 1939, when Germany invaded Poland, World War II lasted until both the Germans and the Japanese had surrendered to the Allies in 1945. Here is a timeline of major events during the war.

1939

Sept. 1 may be the official start of World War II, but it didn't start in a vacuum. Europe and Asia had been tense for years prior to 1939 because of the rise of Adolf Hitler and the Third Reich in Germany, the Spanish Civil War, the Japanese invasion of China, the German annexation of Austria, and the imprisonment of thousands of Jews in concentration camps. After Germany's occupation of areas of Czechoslovakia not previously agreed to in the Munich Pact and its invasion of Poland, the rest of Europe realized it couldn't try to appease Germany any longer. The United States tried to remain neutral, and the Soviet Union invaded Finland.
