When Hitler became Chancellor of the Weimar Republic on 30 January 1933 he was by no means master in his own house. Before this could happen he was preoccupied with the 1933 election, and the Enabling Bill of the same year which gave him the means to put through the Nazi revolution that turned Germany into a one-party unitary State. Even then he had still to cope with his own party enemies by the purge of 30 June 1934, an act which established the domination over the army which Röhm and his S.A. had made so difficult for him. Not until the death of Hindenburg in August 1934 was Hitler in supreme control as Führer und Reichskanzler.
