Holstein-Gottorp

Holstein-Gottorp was a historic duchy in northern Germany, formed in the 18th century through a union of the Holstein and Gottorp regions. It was part of the larger Duchy of Holstein and linked to the Swedish and Russian royal families through marriage alliances. The territory played a significant role in European politics, especially as a hereditary seat for certain royal figures. Today, its historical lands are part of modern Germany, and the name persists in discussions of European royal history and regional heritage.
