Reichstag fire
The Reichstag fire on 27 February was blamed by Hitler's government on the Communists. Hitler used the ensuing state of emergency to obtain the presidential assent of Hindenburg to issue the Reichstag Fire Decree the following day. The decree invoked Article 48 of the Weimar Constitution and "indefinitely suspended" a number of constitutional protections of civil liberties, allowing the Nazi government to take swift action against political meetings, arresting and killing the Communists.
