Robert de Mowbray

Robert de Mowbray (died 1125), a Norman, was Earl of Northumbria from 1086 until 1095. Robert joined the 1088 rebellion against King William II on behalf of Robert Curthose, but was pardoned and later led the army that killed Malcolm III of Scotland at Alnwick. In 1095, he conspired to put Stephen of Aumale on the throne, was besieged by the king, and captured. As punishment, his marriage was dissolved and his lands confiscated, given to the new husband of his former wife, while Mowbray was imprisoned for life and later became a monk.
