- Member of the National Assembly
- Prussian Minister-President in 1920 and from 1921 to 1932
Otto Braun started his political career in Prussia during the Kaiserreich, serving as a member of the Prussian parliament from 1913 to 1918. In 1919, Braun was elected to the constituent National Assembly. Yet he became particularly well known and played a key political role as the Minister-President of Prussia. He served in this capacity in 1920 and, with a brief interruption, from 1921 to 1932. He stayed in office for so long that he came to be known as Prussia’s “Red Czar”. Prussia was Germany’s largest and most populous state by far. As such, its government’s long period of political stability was a major source of support for the Weimar Republic throughout its crises. Braun’s cabinet could not be shaken until finally, with the Papen government’s Preußenschlag (Prussian coup d’état), it was dismissed and its political power was transferred to commissioners. The Preußenschlag made it easier for the Nazis to seize power because they were able to take advantage of the provision in 1933.
