Frederick V, Count of Zollern died at which ancestral seat atop Mount Hohenzollern?
Frederick V, Count of Zollern Friedrich V. of Zollern (died: 24 May 1289 at Hohenzollern Castle) nicknamed, "the Illustrious" was a Count of Zollern.
Principality of Bayreuth The Principality of Bayreuth (German: "Fürstentum Bayreuth" ) or Margraviate of Brandenburg-Bayreuth ("Markgraftum Brandenburg-Bayreuth") was an immediate territory of the Holy Roman Empire, ruled by a Franconian branch of the Hohenzollern dynasty. Since Burgrave Frederick VI of Nuremberg was enfeoffed with the Margraviate of Brandenburg in 1415/17, the Hohenzollern princes transferred the margravial title to their Franconian possessions, though the principality never had been a march. Until 1604 they used Plassenburg Castle in Kulmbach as their residence, hence their territory was officially called the Principality of Kulmbach or Margraviate of Brandenburg-Kulmbach until the Empire's dissolution in 1806.
