Frederick IV, Burgrave of Nuremberg

Frederick IV (c. 1287 – 19 May 1332) was Burgrave of Nuremberg from 1300, until his death in 1332. He was the younger son of Burgrave Frederick III from his second marriage with the Ascanian princess Helene of Saxony.

Life
He succeeded to the burgraviate when his elder brother John I died in 1300. In 1307, he and King Albert I of Germany led an Imperial Army into the Battle of Lucka against the Wettin margraves Frederick I of Meissen and Dietrich IV of Lustia, and were defeated. Frederick IV fought more successfully alongside the Wittelsbach king Louis the Bavarian at the Battle of Mühldorf on 28 September 1322, capturing the Habsburg rival Frederick the Fair.

In 1331 he purchased the town of Ansbach, nucleus of the later Hohenzollern Principality of Ansbach established in 1398. A year later Frederick died, and was succeeded by his son, John II.
