At 9.25pm, the Berlin fire station receieved an alarm call that the Reichstag building, the assembly location of the German Parliament, was ablaze.
By the time the firefighters came, the main Chamber of Deputies was engulfed by flames.
The fire was used as evidence by the Nazis that the Communists were beginning a plot against the German government. Adolf Hitler, who had been sworn in as Chancellor of Germany four weeks before, on 30 January, urged President Paul von Hindenburg to pass an emergency decree to counter the "ruthless confrontation of the Communist Party of Germany".
With civil liberties suspended, the government instituted mass arrests of Communists, including all of the Communist parliamentary delegates. With them gone and their seats empty, the Nazis went from being a plurality party to the majority; subsequent elections confirmed this position and thus allowed Hitler to consolidate his power.
Well,historians disagree as to whether Van der Lubbe acted alone or if the Communists or Nazis were involved. The responsibility for the Reichstag fire remains an ongoing topic of debate and research.
