The German Revolution of 1918–1919, also known as the November Revolution, was an uprising started by workers and soldiers in the final days of World War I. It quickly and almost bloodlessly brought down the German Empire, then in its more violent second stage, the supporters of a parliamentary republic were victorious over those who wanted a soviet-style council republic. The defeat of the forces of the far Left cleared the way for the establishment of the Weimar Republic.

World War I or the First World War was a global conflict between two coalitions: the Allies and the Central Powers. Fighting took place throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. One of the deadliest wars in history, it resulted in an estimated 9 million soldiers dead and 23 million wounded, plus up to 8 million civilian deaths from numerous causes including genocide. The movement of large numbers of troops and civilians during the war was a major factor in spreading the 1918 Spanish flu pandemic.
