1939+Nazi+Soviet+Pact

This was a Soviet-German nonaggression pact in 1939, which shocked the Allies since historically, Germany and the Soviet Union had despised each other. they were also surprised since it was a pact made between different government types: Germany with a dictatorship and the communist Soviet Union.
 * Definiton**

This nonaggression pact is significant because it emphasizes Hitler's illegal methods to keep his power. We know that later on, Hitler breaks this pact by deciding to invade the Soviet Union anyways. This later causes the Soviet Union to switch to supporting the Allies instead of the Axis.
