Gerhard VII of Diez

Gerhard VII was the last Count of Diez, succeeding his father Gerhard VI after the latter was killed fighting Limburg in 1343. His family's influence had declined since the fall of the Hohenstaufen dynasty, and by Gerhard's time the once Golden County had been heavily pledged to creditors to settle debts.

He married Gertrud of Westerburg, and their daughter Jutta became his heiress. When Gerhard died in 1388 without a male heir, the County of Diez passed through Jutta to her husband, Adolf I, Count of Nassau-Siegen, ending Diez rule.
