Reichstag building: The Reichstag (German: "Reichstagsgebäude" ] ; officially: "Deutscher Bundestag - Plenarbereich Reichstagsgebäude" ] ) is a historic edifice in Berlin, Germany, constructed to house the Imperial Diet (German: "Reichstag"), of the German Empire.

Reichstag fire: The Reichstag fire (German: "Reichstagsbrand" , ) was an arson attack on the Reichstag building (home of the German parliament) in Berlin on 27 February 1933, just one month after Adolf Hitler had been sworn in as Chancellor of Germany.  The Nazis stated that Marinus van der Lubbe, a Dutch council communist, was found near the building.  The Nazis publicly blamed the fire on communist agitators in general, although in a German court in 1933, it was decided that Van Der Lubbe had acted alone, as he claimed to have done.  After the fire, the Reichstag Fire Decree was passed.  The fire was used as evidence by the Nazi Party that communists were plotting against the German government.  The event is seen as pivotal in the establishment of Nazi Germany.
