Background
He was the son of Margrave Christian Heinrich of Brandenburg-Kulmbach and his wife Sophie Christiane of Wolfstein.
governor of the Duchies of Schleswig
He was the son of Margrave Christian Heinrich of Brandenburg-Kulmbach and his wife Sophie Christiane of Wolfstein.
His most significant position was governor of the Duchies of Schleswig and Holstein-Glückstadt. At the time, Denmark was in personal union with the Duchies of Schleswig and Holstein-Glückstadt, the royal share in the Duchy of Holstein. In 1731, he received Gottorf Castle as his seat, the former seat of the Dukes of Schleswig and Holstein at Gottorp.
However, he preferred to build his own residence at the site of the manor at Drage, which the king had given to him on the occasion of his wedding with Christine Sophie, the daughter of Duke Ernest Ferdinand of Brunswick-Bevern.
The old manor house was demolished and Friedrichsruh Castle was constructed between 1744 and 1751, after a design of the Danish court architect Nicolai Eigtved. He was succeeded as governor of Schleswig and Holstein-Glückstadt by Friedrich Ludwig von Dehn.
The Margrave Room in Glücksburg Castle is named after Frederick Ernest. He resided there for a while.
