Weimar Republic (1919–1933)

Billboard advertising Die Dreigroschenoper by Bertolt Brecht. The Weimar era was dominated by political unrest.

At the beginning of the German Revolution, Germany was declared a republic and the monarchy collapsed. However, the struggle for power continued, with radical-left communists seizing power in Bavaria, but failing to take control of all of Germany. The revolution came to an end in August 1919, when the Weimar Republic was formally established. The Weimar Constitution came into effect with its signing by President Friedrich Ebert on 11 August 1919.

Suffering from the Great Depression, the harsh peace conditions dictated by the Treaty of Versailles, and a long succession of more or less unstable governments, the people of Germany increasingly lacked identification with their political system and the "Establishment Parties" in their parliamentary democracy. This was exacerbated by a widespread right-wing (monarchist, völkisch, and Nazi) Dolchstoßlegende, which promoted the view that Germany had lost World War I because of the efforts and influence of those who wanted to overthrow the government. The top brass of the Weimar government was accused of betraying the German Nation by signing the Versailles Treaty, while the radical left-wing communists, such as the Spartacist League, had wanted a revolution to abolish "capitalist rule" in favour of a Räterepublik, and were also targeted.

Nevertheless, discontentment with the new Weimar government helped fuel the growth of the German Communist Party. Many conservatives were drawn towards the reactionary/revolutionary right, particularly the National Socialist German Workers Party—the Nazi Party. By 1932, these two parties controlled the majority of parliament (296 total parliamentary seats by July 1932). After a series of unsuccessful cabinets, President Paul von Hindenburg made a crucial decision: on 30 January 1933, seeing little alternative and pushed by right-wing advisors, von Hindenburg appointed Adolf Hitler as Chancellor of Germany, honoring Hitler's request.
