Robert Fitzharding (c. 1095–1170) was an Anglo-Saxon nobleman from Bristol who was granted the feudal barony of Berkeley in Gloucestershire. He rebuilt Berkeley Castle, and founded the Berkeley family which still occupies it today. He was a wealthy Bristol merchant and a financier of the future King Henry II of England (1133-1189) in the period known as the Anarchy during which Henry's mother, the Empress Matilda (1102-1167), mounted repeated military challenges to King Stephen (d. 1154). Fitzharding founded St. Augustine's Abbey, which after the Reformation became Bristol Cathedral. Many members of the Berkeley family were buried within it, and some of their effigies survive there. As J. Horace Round asserted he was one of the very few Anglo-Saxon noblemen who managed to retain their noble status in Norman England and successfully integrate with the Norman nobility, if not the only one.Round, J.
