The German High Seas Fleet is incapacitated when sailors mutiny, an action which would trigger the German Revolution of 1918–19.

The German Empire, also referred to as Imperial Germany, the Second Reich or simply Germany, was the period of the German Reich from the unification of Germany in 1871 until the November Revolution in 1918, when the German Reich changed its form of government from a monarchy to a republic. The German Empire consisted of 25 states, each with its own nobility: four constituent kingdoms, six grand duchies, five duchies, seven principalities, three free Hanseatic cities, and one imperial territory. While Prussia was one of four kingdoms in the realm, it contained about two-thirds of the Empire's population and territory, and Prussian dominance was also constitutionally established, since the King of Prussia was also the German Emperor.

The High Seas Fleet was the battle fleet of the German Imperial Navy and saw action during the First World War. In February 1907, the Home Fleet was renamed the High Seas Fleet. Admiral Alfred von Tirpitz was the architect of the fleet; he envisioned a force powerful enough to challenge the Royal Navy. Kaiser Wilhelm II, the German Emperor, championed the fleet as the instrument by which he would seize overseas possessions and make Germany a global power. By concentrating a powerful battle fleet in the North Sea while the Royal Navy was required to disperse its forces around the British Empire, Tirpitz believed Germany could achieve a balance of force that could seriously damage British naval hegemony. This was the heart of Tirpitz's "Risk Theory", which held that Britain would not challenge Germany if the latter's fleet posed such a significant threat to its own.

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.
