King in Prussia
The Prussian Navy was created in 1701 from the former Brandenburg Navy upon the dissolution of Brandenburg-Prussia, the personal union of Brandenburg and Prussia under the House of Hohenzollern, after the elevation of Frederick I from Duke of Prussia to King in Prussia. The Prussian Navy fought in several wars but was active mainly as a merchant navy throughout the 18th and 19th centuries, as Prussia's military consistently concentrated on the Prussian Army. The Prussian Navy was dissolved in 1867 when Prussia joined the North German Confederation, and its naval forces were absorbed into the North German Federal Navy.
