The Reichstagbrand, or Reichstag Fire, occurred on February 27, 1933, when the German parliament building in Berlin was set ablaze. The Nazis, led by Adolf Hitler, seized the opportunity to claim that the fire was part of a communist plot, using it as a pretext to suppress political opposition and consolidate power. The event led to the Reichstag Fire Decree, which suspended civil liberties and allowed for the arrest of many political opponents, paving the way for the establishment of a totalitarian regime.
