This day in history (February 27, 1933): The German Reichstag building is destroyed by a fire. This event was a major turning point in German history as it was used by the Nazi Party as a pretext for state repression.
The Nazis blamed Dutch communist Marinus van der Lubbe for starting the fire. Nazi leader and Chancellor, Adolf Hitler, used the fire as evidence that the Communists were beginning a plot against the German government. As a result, all civil liberties were suspended and members of the Communist Party were arrested. With them gone, the Nazis were able to fill their seats and become a majority in parliament.
Historians are divided as to whether Van der Lubbe acted alone or whether the arson was planned and ordered by the Nazis.
