Adolf II von der Mark, Prince-Bishop of Liège

Adolf II von der Mark (1288–1344), third son of Eberhard I of the Mark, became Prince-Bishop of Liège in 1313 through King Philip IV. In 1316 resistance forced him to sign the Peace of Fexhe; after trying to revoke it he fled to Huy and put Liège under interdict.

He sold Mechelen to Flanders in 1333 and failed to annex Loon in 1336. The Tribunal of the XXII curbed his authority in 1343, a year before he died.
