Gerhard VI of Diez

Gerhard VI (c. 1298–1343) was Count of Diez, a small county in the Lahn valley known to contemporaries as the Golden County. The son of Count Gottfried III, who was judged unfit to rule, he governed Diez from 1332 during his father's long incapacity.

He married Jutta of Nassau-Hadamar, who bore his successor Gerhard VII. Gerhard was killed on 17 October 1343 in a feud against the nearby city of Limburg, and was the penultimate count of the Diez line.
