Frederick I, of the Hohenzollern dynasty, was Elector of Brandenburg (1688–1713) and Duke of Prussia in personal union (Brandenburg-Prussia). The latter function he upgraded to royalty, becoming the first King in Prussia (1701–1713). From 1707 he was in personal union the sovereign prince of the Principality of Neuchâtel.

The House of Hohenzollern is a formerly royal German dynasty whose members were variously princes, electors, kings and emperors of Hohenzollern, Brandenburg, Prussia, the German Empire, and Romania. The family came from the area around the town of Hechingen in Swabia during the late 11th century and took their name from Hohenzollern Castle. The first ancestors of the Hohenzollerns were mentioned in 1061.
Hohenzollern Castle, near Hechingen, was built in the mid-19th century by Frederick William IV of Prussia on the remains of the castle founded in the early 11th century.
