The actual fire in the Reichstag—the German parliament building—burned on the evening of February 27, 1933. Adolf Hitler had been appointed chancellor four weeks earlier, and already he had begun placing restrictions on the press and expanding the powers of the police. But it is the fire, rather than Hitler’s toxic first steps, that is remembered as the event after which things were never the same, in Germany or in the world. The day after the fire, the government issued a decree allowing the police to detain people without charges, on the grounds of prevention.
