Robert de Mowbray

Robert de Mowbray was the earl of Northumbria from 1086 when Aubrey de Coucy's lands and titles were finally redistributed and held that post until 1095 when he was deposed for rebelling against William Rufus, king of England. He was the nephew of Geoffrey de Montbray, bishop of Coutances.

He joined the Rebellion of 1088 and later rebelled in 1095. In that year, he refused to come to William's Curia Regis, the thrice-annual court where decisions were made and delivered to the great lords, and William subsequently led an army against him and defeated him; the earl was dispossessed and imprisoned. After him, the ancient earldom of the Anglo-Saxons is left vacant for quite some time. It is not really filled again until the time of the Percys in the fourteenth century.
