- William FitzOsbern, 1st Earl of Hereford
William fitzOsbern (c. 1020 –
February 22, 1071), Lord of Breteuil, in Normandy, was a relative and close counsellor of William the Conqueror.
1st Norman Earl of Hereford
He was the son of
Osbern the Steward, a nephew of Duchess Gunnor, the wife of Duke Richard I of Normandy. Osbern became the steward of his cousin Duke Robert I of Normandy, and when Robert left the Duchy to his young son William, Osbern was one of Duke William's guardians. Osbern was killed defending the person of Duke William against an assassinationattempt, sometime around 1040.
Osbern had married Emma, a daughter of Count
Rodolf of Ivry, who was a half-brother of Duke Richard I of Normandy. Through her he inherited a large property in central Normandy, including the honours of Pacyand Breteuil.
William fitzOsbern was probably raised at the court of his cousin and namesake Duke William, and like his father, became one of the ducal stewards. He was one of the earliest and most vigorous advocates of the invasion of England, and tradition holds that he convinced the doubters amongst the Norman
barons of the feasibility of the invasion.
FitzOsbern's younger brother Osbern was one of
Edward the Confessor's chaplains, and possessed the rich church of Boshamin Sussex, and was well-placed to pass along intelligence on the situation in England. He later became Bishop of Exeter.
In England after 1066
As Duke William took control of England (becoming William I of England), fitzOsbern was given charge of the
Isle of Wight, and then before 22 February 1067 he was made Earl of Herefordas well as Gloucester, Worcester and Oxfordshire. In this King William was imitating the earldom of his predecessor, Harold Godwinson.
Challenge and reward
In any case, that part of England was not yet under Norman control; the understanding must have been that fitzOsbern was to take charge of their conquest when he was able. Also for the central part of 1067 the King returned to Normandy, leaving fitzOsbern, along with
Odo of Bayeux, in charge of England.
ubduing Southwest England
The King was back in England in 1068, and fitzOsbern accompanied him in the subdual of southwest England. He attended the King's
Whitsuncourt in May, and then himself paid a visit to Normandy, where he fell ill for some months.
In charge at York
In February or March 1069 fitzOsbern was given charge of the new castle at
York, but he returned south in time to attend the King's Eastercourt in April.
ubduing the West Midlands
Invasion of Gwent
During this time fitzOsbern and his followers pushed on into
Wales, beginning the conquest of the Welsh Gwent.
As part of the assertion of Norman control over England (and Wales), fitzOsbern was one of the major Norman
castlebuilders. Early castles attributed to him include Carisbrooke on the Isle of Wightand then in South WalesChepstow ( Striguil), Wigmore, Clifford Castleand Monmouth Castle, as well as creating or improving the fortifications of the towns of Herefordand Shrewsbury.
Distraction and death in Flanders
In 1070 trouble arose in
Flanders, where King William's brother-in-law Baldwin VI of Flandershad died, leaving his county and his young sons in the hands of his widow Richilde, Countess of Mons and Hainaut. Her control of Flanders was challenged by the brother of her late husband, Robert the Frisian. Looking for help, she offered herself in marriage to fitzOsbern. He could not resist the chance to become also Count of the rich Principality in the German Empire, close to Normandy. He hurried there with his army, but nevertheless was defeated by the Count of Flanders: fitzOsbern lost his life in the Battle of Cassel on February 22, 1071.
He was succeeded in Normandy by his eldest son,
William of Breteuil, and in England and Wales by his younger son, Roger de Breteuil. His daughter Emma married Ralph de Gael, 1st Earl of Norfolk.
He lived in Carisbrooke Castle.
