On the night of 27 February 1933, the Reichstag building was set afire. Marinus van der Lubbe, a Dutch communist, was found guilty of starting the blaze. Hitler proclaimed that the arson marked the start of a communist uprising. The Reichstag Fire Decree, imposed on 28 February 1933, rescinded most civil liberties, including rights of assembly and freedom of the press. The decree also allowed the police to detain people indefinitely without charges. The legislation was accompanied by a propaganda campaign that led to public support for the measure. Violent suppression of communists by the SA was undertaken nationwide and 4,000 members of the Communist Party of Germany were arrested.
