The Kiel mutiny was a major revolt by sailors of the German High Seas Fleet on 3 November 1918. The revolt triggered the German revolution which was to sweep aside the monarchy within a few days. It ultimately led to the end of the German Empire and to the establishment of the Weimar Republic.
By September 1918, Germany's military situation was close to hopeless. Kaiser Wilhelm II was advised to request the Entente Cordiale for an immediate cease fire and put the government on a democratic footing, hoping for more favorable peace terms.
On 3 October, the Kaiser appointed Prince Maximilian of Baden as the new imperial chancellor. In his cabinet the Social Democrats (SPD) also took on responsibility. The most prominent and highest-ranking was Philipp Scheidemann, a prominent leader of the SPD as undersecretary without portfolio.
Following the Battle of Jutland, the capital ships of the imperial navy had been confined to inactive service in harbor. Many officers and crewmen had volunteered to transfer to the submarines and light vessels which still had a major part to play in the war. The discipline and spirit of those who remained, on lower rations, with the battleships tied up at dock-side, inevitably suffered. On 2 August 1917, 350 crewmen of the dreadnought Prinzregent Luitpold staged a protest demonstration in Wilhelmshaven. Two of the ringleaders were executed by firing squad while others were sentenced to prison. During the remaining months of the war, secret sailors' councils were formed on a number of the capital ships.
In October 1918, the imperial naval command in Kiel under Admiral Franz von Hipper planned to dispatch the fleet for a final battle against the Royal Navy in the English Channel. The naval order of 24 October 1918 and the preparations to sail triggered a mutiny among the affected sailors and then a general revolution which was to sweep aside the monarchy within a few days.
