In the 1932 federal election, the Nazis secured 230 seats in the Reichstag, making them the largest single party but without a controlling majority. Six months later, President Paul von Hindenburg invited Hitler to become Chancellor, after which the latter cemented Nazi dominance over the government. In February 1933, Hitler convinced von Hindenburg to issue the Reichstag Fire Decree, legally suspending civil liberties. Himmler, who was newly appointed as the police chief of Munich, ordered the arrests of those he regarded as a threat to the Nazis—including journalists, labour organisers, Jewish community leaders, socialists, and communists—and their incarceration in Dachau concentration camp. Hitler approved of Himmler's tactics and appointed him head of the political police across Germany.
