For those not familiar with history:
The Reichstag fire was an arson attack on the Reichstag building (the German Capitol).
On Monday 27 February 1933, precisely four weeks after Adolf Hitler was elected Chancellor of Germany, the Reichstag was set on fire.
Nazi Party used the fire as a pretext to claim that communists were plotting against the German government by issuing mass arrests of political opponents and suspending most civil liberties, including habeas corpus, freedom of expression, freedom of the press, the right of free association and public assembly, and the secrecy of postal services and telephone by decree.
Hitler, after having obtained his emergency powers, announced that it was the start of an insurrection to take over Germany. Nazi Party newspapers then published this fabricated "news".[18]
Some lone nut (Van der Lubbe) being responsible the Nazis sought to make it appear to be insurgents that set the fire.
The responsibility for the Reichstag fire remains a topic of debate and research. Some historians believe, based on archive evidence, that the arson had been planned and ordered by the Nazis as a false flag operation.
