World War II
After the  end of the German Empire, the democratic Weimar Republic was set up. There were disagreements among Germans that involved many political ideologies, ranging from nationalism to communism. The fascist movement in Germany rose because of the Great Depression. Adolf Hitler, the leader of the Nazi Party, became the German chancellor in 1933. After the Reichstag fire, Hitler created a totalitarian state in which there was only one party by law. Hitler wanted to change the world order and quickly rebuilt the army, navy, and air force, especially after Saarland voted to return to Germany in 1935. In March 1936, Hitler sent the army to Rhineland. The Spanish Civil War began in July 1936. The war ended in 1939 with the Nationalist victory because of support from Italy and Germany.
