A similarly named office existed in the Prussian Navy and the Kriegsmarine of Nazi Germany.
With the same obligations and rights as a commanding general of the army, this admiral fulfilled the duties of a Chief of the Naval Staff.
Under instructions from the emperor, he commanded all naval units at sea and ashore.
This happened mainly at the instigation of Admiral Alfred von Tirpitz, to increase the power of his Imperial Naval Office (Reichsmarineamt).
Some of the powers of the Imperial Naval High Command were transferred to the previously existing Admiralty Staff.
