Paul von Hindenburg is overheard making some condescending remarks about Catholics in general and Bavarian Catholics in special during the 1925 presidential election campeign. As a result he loses a significant part of the BVP votes and Wilhelm Marx (Zentrum) is elected and in 1932 reelected as Reichspräsident.
When the DVP walks out of the multiparty (SPD-Zentrum-DDP-DVP) coalition government in 1930 he provides Chancellor Hermann Müller (SPD) with the emergency powers of Article 48 to continue his rump SPD-Zentrum-DDP coalition minority government (after Müller's death in 1931 under the chancellorship of Heinrich Brüning (Zentrum)), a support he would continue to provide even after the significant losses of the grand coalition parties in the 1932 Reichstag elections (with substantial gains for both the far-right NSDAP and the far-left KPD) and Otto Wels (SPD) replacing Brüning as Chancellor.
After the 1936 elections result in slight gains for the grand coalition government parties and the moderate centre-right DVP and a majority government can, at least mathematically, be once again formed from moderate parties the DVP decides to enter the grand coalition once again after being promised several important cabinet positions.
