Bullock, the heaviest responsibility lay with the German right wing, who "forsook a true conservatism" and made Hitler their partner in a coalition government. The Centre Party's Heinrich Brüning was Chancellor from 1930 to 1932. Brüning and Hitler were unable to reach terms of co-operation, but Brüning himself increasingly governed with the support of the President and Army over that of the parliament. The 84-year-old President von Hindenburg, a conservative monarchist, was reluctant to take action to suppress the Nazis, while the ambitious Major-General Kurt von Schleicher, as Minister handling army and navy matters hoped to harness their support. With Schleicher's backing, and Hitler's stated approval, Hindenburg appointed the Catholic monarchist Franz von Papen to replace Brüning as Chancellor in June 1932. Papen had been active in the resurgence of the Harzburg Front. He had fallen out with the Centre Party. He hoped ultimately to outmaneuver Hitler. At the July 1932 federal election, the Nazis became the largest party in the Reichstag, yet without a majority. Hitler withdrew support for Papen and demanded the Chancellorship. He was refused by Hindenburg. Papen dissolved Parliament, and the Nazi vote declined at the November election. In the aftermath of the election, Papen proposed ruling by decree while drafting a new electoral system, with an upper house. Schleicher convinced Hindenburg to sack Papen, and Schleicher himself became Chancellor, promising to form a workable coalition. The aggrieved Papen opened negotiations with Hitler, proposing a Nazi-Nationalist Coalition. Having nearly outmaneuvered Hitler, only to be trounced by Schleicher, Papen turned his attentions on defeating Schleicher, and concluded an agreement with Hitler.

Days after the ban, SA-men shot dead two communists in a street fight, which led to a ban being placed on the public speaking of Goebbels, who sidestepped the prohibition by recording speeches and playing them to an audience in his absence. When Hitler's citizenship became a matter of public discussion in 1924 he had a public declaration printed on 16 October 1924, Under the threat of criminal deportation home to Austria, Hitler formally renounced his Austrian citizenship on 7 April 1925, and did not acquire German citizenship until almost seven years later; therefore, he was unable to run for public office. Hitler gained German citizenship after
