Urse d'Abetot was a Norman who followed King William I to England, and became Sheriff of Worcestershire and a royal official under him and Kings William II and Henry I. He was a native of Normandy and moved to England shortly after the Norman Conquest of England in 1066, and was appointed sheriff in about 1069. Little is known of his family in Normandy, who were not prominent, but he probably got his name from the village Abetot. Although Urse's lord in Normandy was present at the Battle of Hastings, there is no evidence that Urse took part in the invasion of England in 1066.

Henry I, also known as Henry Beauclerc, was King of England from 1100 to his death in 1135. He was the fourth son of William the Conqueror and was educated in Latin and the liberal arts. On William's death in 1087, Henry's elder brothers Robert Curthose and William Rufus inherited Normandy and England, respectively, but Henry was left landless. He purchased the County of Cotentin in western Normandy from Robert, but his brothers deposed him in 1091. He gradually rebuilt his power base in the Cotentin and allied himself with William Rufus against Robert.
