Adolf II of Waldeck

Adolf II (c. 1258–1302), eldest son of Count Henry III of Waldeck, succeeded his grandfather Adolf I as ruling count in 1270. After he failed to marry Sophia of Hesse, a family treaty of 1275 gave the county to his brother Otto I, and Adolf entered the Church, holding posts in Liège, Trier and Utrecht.

In 1301 he was appointed prince-bishop of Liège, where he reconciled clergy and burghers. He died in December 1302, rumoured poisoned by the moneylenders he had persecuted.
