The SKL was established on August 27, 1918, on the initiative of Admiral Reinhard Scheer, who became its first commander, simultaneously to being the Chief of the German Imperial Admiralty Staff. It led the planning and execution of naval combat and directed the distribution of naval forces. Up to this point, that was done by several staffs and the individual theater commanders; including the Supreme Army Command under General Erich Ludendorff, whose decisions led to the unrestricted submarine warfare and the entrance of the United States into the war.
