After the German Empire was disestablished, the democratic Weimar Republic was set up. There were disagreements between the Germans which involved many political ideologies, ranging from nationalism to communism. The fascist movement in Germany rose because of the Great Depression. Adolf Hitler, leader of the Nazi Party, became the Chancellor in 1933. After the Reichstag fire, Hitler created a totalitarian state, where there is only one party by law. Hitler wanted to change the world order and quickly rebuilt the army, navy and air force, especially after Saarland was reunited in 1935. In March 1936, Hitler sent the army to Rhineland. The Spanish Civil War began in July 1936. The war ended with the nationalist victory, supported by Italy and Germany.
