The Interwar Period describes the period of time between the end of World War I and the start of World War II (1919-1939). The Treaty of Versailles, the peace treaty that brought World War I to an end, left European countries like Germany economically crippled, and resulted in re-drawn borders and economic depression. This paved the way for dictators to rise in countries like Italy, the Soviet Union, Japan and Germany. Propaganda was commonly used to influence the public. The extremist nature of the political ideologies in Europe would eventually fuel conflict leading to World War II.
