House Of Holstein-Gottorp

The House of Holstein-Gottorp, a cadet branch of the Oldenburg dynasty, ruled Sweden from 1751 until 1818, and Norway from 1814 to 1818. The current royal family, Bernadotte, is de jure a branch of the Holstein-Gottorps due to the last Holstein-Gottorp king's adoption of the first Bernadotte king, Charles XIV John.
