Partial (junior) possessors 1544-1773: Dukes of Holstein-Gottorp

Formal title of the duke was "Duke of Schleswig, Holstein, Dithmarschen and Stormarn", but that also was born by his cousins, as it was their common property. The Gottorp branch held Landeshoheit in the case of the duchy of Holstein in Holy Roman Empire and in the case of the duchy of Schleswig in the kingdom of Denmark. The name Holstein-Gottorp comes as convenient usage from technically more correct Duke of Schleswig and Holstein at Gottorp.

The oldest of the ducal titles was that of Schleswig, which had been confirmed to their cognatic predecessors ultimately in 1386 by King Oluf II of Denmark and his mother-regent, Queen Margaret I.^{[citation needed]} Ducal title to Holstein and so forth came in 1474 from Frederick III, Holy Roman Emperor.

From 1544, when this "one-thirds-duchy" was ceded to Adolf, the third son of King Frederick I of Denmark and the youngest half-brother of King Christian III of Denmark. The Holstein-Gottorp house was therefore a cadet branch of the House of Oldenburg and the various Dukes of Holstein-Gottorp shared the rule of Schleswig and Holstein with their relatives, the Kings of Denmark. Roughly one-third of the lands were controlled by the Dukes.
