Counts · Landgraviate of Thuringia · as at first light, 1 January 1200

Wildungen

The landgrave's brother, a former Mainz cleric who married the heiress of Count Gozmar III of Ziegenhain in 1185 and with her claimed the Ziegenhain and Reichenbach inheritance against Gozmar's brother Rudolf II and his sons.

He holds Wildungen in the Eder hills with the title of count, and is advocate of Staufenberg on the Lahn and of the Reichenbach lands; the Ziegenhain title he uses is nominal. His Friedrichstein castle above Alt-Wildungen is dated 'in 1200', so it may not stand yet on 1 January.
