When the German parliament building, the Reichstag, was burned down by an arsonist on February 27, 1933-- the Nazis retaliated by cracking down on their political opponents. All 100 Communist party members of the German parliament were arrested and a communist named Marinus van der Lubbe was convicted of setting the fire.

By the end of 1933, all other political parties were banned, and the Nazi party took complete control of the German state.
