The German Revolution of 1918–19 begins when 40,000 sailors take over the port in Kiel.

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. The key factors leading to the revolution were the extreme burdens suffered by the German people during the war, the economic and psychological impacts of the Empire's defeat, and the social tensions between the general populace and the aristocratic and bourgeois elite.

The Kiel mutiny was a revolt by sailors of the German High Seas Fleet against the maritime military command in Kiel. The mutiny broke out on 3 November 1918 when some of the ships' crews refused to sail out from Wilhelmshaven for the final battle against the British Grand Fleet that the Admiralty had ordered without the knowledge or approval of the German government. The mutineers, who saw the planned battle as a futile "death voyage", took over Kiel with workers' and soldiers' councils and then helped spread them across Germany. The German Revolution that was triggered by the councils swept aside the Hohenzollern monarchy within a few days, brought about the end of the German Empire and led to the establishment of the Weimar Republic.

Kiel is the capital and most populous city in the northern German state of Schleswig-Holstein. With a population of around 250,000, it is Germany's largest city on the Baltic Sea. It is located on the Kieler Förde inlet of the Bay of Kiel and lies in the southeast of the Jutland Peninsula, on the mouth of the Schwentine River, approximately 90 kilometres (56 mi) northeast of Hamburg. The world's busiest artificial waterway, the Kiel Canal, has a terminus in Kiel's Holtenau district. This canal connects the Baltic to the North Sea, with its other end in Brunsbüttel. Most of Kiel is part of Holstein. The boroughs north of the Schwentine also belong to Wagria, while those north of the Kiel Canal are historically part of Southern Schleswig.
