Paul von Hindenburg is the new and former Reichspräsident. In the second ballot he narrowly gains an absolute majority (53%), ahead of Hitler (36.8%) and Thälmann (10.2%). In order to avoid Hitler becoming president, primarily the SPD, the German State Party and the Center Party come out in favor of Hindenburg’s re-election. Ironically, it is precisely these parties which tried to prevent Hindenburg’s election in 1925.

Following the presidential elections, numerous pieces of evidence pointing towards NSDAP mobilization and subversion plans are found during house searches. Subsequently, numerous representatives from the various federal state governments push for a ban on the SA and the SS. Groener and Brüning manage in the end to also persuade Schleicher and Hindenburg of the ban, resulting in the “Emergency Decree on the Protection of the Authority of the State” entering into force on 13 April.

The NSDAP makes significant gains in the federal state elections in Hamburg, Anhalt, Bavaria, Württemberg and Prussia. In four of the five states, the NSDAP becomes the largest parliamentary group in the Landtag. Only in Bavaria does the BVP maintain its lead over the NSDAP, remaining the largest parliamentary group. Despite the electoral success for the NSDAP, only in Anhalt does the party form part of the government, which is then headed by Nazi party member Alfred Freyberg.
