Why did the German navy mutiny at Kiel during World War 1?

The context was that the national government had already started negotiating an armistice with the allies, and the whole country knew the Great War was approaching its end. With the exception of the U-boat division, the German Navy had not done well during the previous four years. Senior Fleet officers (undisclosed to Max von Baden, the Chancellor in Berlin, who would have refused permission) decided to have a final fling at the Royal Navy, more to boost their own sagging egos than for any other good military reason. Word got out, and the crews refused to sail from Kiel. Wilhelmshavn quickly followed suit. Although command of the naval bases was promptly relieved and replaced, the movement grew; in quick succession, there were civilian uprisings in several inland cities, the socialists declared revolution in Berlin, Bayern seceded from the Nation, and the Kaiser abdicated.
