The Reich government and Reichspräsident Hindenburg impose imperial authority over Prussia. The “Prussian Coup”, which was set up by Schleicher, Reichskanzler Papen and Interior Minister Wilhelm Freiherr von Gayl, puts the office of the Prussian Minister-President in the hands of the Reichskanzler. Furthermore, a Reich Commissioner is appointed who is given the powers of the Prussian interior minister. This gives the Reich leadership virtually unlimited access to the Prussian government institutions. Efforts are made within the SPD and the KPD to resist this, but the division within the labor force and the determination of the Reichswehr to suppress any insurgency mean that there is no open revolt. The demission of the SPD-led Prussian government means the SPD loses its last possibility to exert influence in the Reich and that it is politically isolated in the period that follows.

The NSDAP increases its share of the vote O.C. again in the Reichstag elections. The party becomes the largest in the Reichstag with 37.4% of the vote. Just 21.6% of votes are for the SPD. The DNVP (6.2%), the DVP (1.2%) and the German State Party (1.0%) also win far fewer seats than in the last election. Besides the NSDAP, the Center Party (12.5%) and the KPD (14.5%) are the only other parties to make slight gains.
