In 1933 fire broke out in the building, destroying much of the Reichstag. It is to date still unclear who started the fire, but the Communists were blamed. It gave a boost to Hitler's Party, the NSDAP, who would soon come to power.The building was damaged even more at the end of the war, when the Soviets entered Berlin. The picture of a Red Army Soldier raising the Soviet flag on the Reichstag is one of the most famous twentieth century images and symbolized Germany's defeat.
