Frederick of Zollern

Frederick of Zollern, born before 1325, was Prince-Bishop of Regensburg from 1340 to 1365, a son of Burgrave Frederick IV of Nuremberg and Margaret of Görz-Tyrol. His brothers John and Berthold became burgrave and Bishop of Eichstätt.

After Bishop Nicholas of Ybbs died, most of the chapter chose Frederick, but Emperor Louis the Bavarian backed a rival, Heinrich of Stein. Both claimants pledged castles and borrowed heavily, and the bishopric was left deeply in debt. Heinrich withdrew in 1345 and the emperor accepted Frederick.

He later gave Donaustauf Castle to Emperor Charles IV, over the chapter's protests, and in 1349 saw plague empty villages across his diocese. He resigned in 1365 and died before February 1368.
