The document provides an overview of the Interwar Period from 1919-1939. It summarizes that after World War 1, hopes for peace failed as the Russian Revolution led to Stalin's regime in Russia and the 1929 stock market crash triggered a global economic depression. During this time, totalitarian regimes like fascism in Italy under Mussolini and Nazism in Germany under Hitler rose to power and imposed cruel dictatorships through repression of opposition and harsh racism and nationalism.
