The Prussian Navy (German: Preußische Marine), was the naval force of the Kingdom of Prussia. It was created from the former Brandenburg Navy, following the elevation of the Duke of Prussia to King in Prussia in 1701. At that time, Brandenburg and Prussia formed a double state ruled in personal union by the House of Hohenzollern. The Prussian Navy existed, without any long interruption, until the founding of the North German Confederation in 1867, at which point the Prussian Navy was absorbed into the Norddeutsche Bundesmarine (North German Federal Navy).
