Robert, 1st Earl of Gloucester, was an illegitimate son of Henry I and the most important military supporter of his half-sister Empress Matilda during the Anarchy. A wealthy cross-Channel magnate, he provided troops, castles and political credibility to her claim.
Robert captured King Stephen at Lincoln in 1141 but was himself captured at Winchester and exchanged for the king. His death in 1147 seriously weakened Matilda’s cause. Robert, 1st Earl of Gloucester was born in Caen and died in Bristol.
In Ellis Peters’ Brother Cadfael’s Penance, in late 1145, England remains divided between King Stephen and Empress Matilda, and an attempted peace meeting at Coventry fails to end the conflict. Brother Cadfael learns that Olivier de Bretagne, the son whose existence he has kept secret, disappeared after the surrender of Faringdon Castle and may be held by men whose loyalties have shifted during the war. Cadfael leaves Shrewsbury without formal permission and enters the contested country around Gloucester and the Thames Valley. In Derek Birks’ Rebel Sword, Robert, Earl of Gloucester, initially accepts Stephen’s rule, but the political settlement begins to fracture. Robert’s illegitimate son Thomas, raised in a Norman household but conscious of his Saxon mother’s heritage, is more interested in tavern fights and personal grievances than dynastic politics until a violent brawl leads to exile on the family estates in Normandy. Thomas’s journey south with his Saxon uncle brings him into the orbit of a young heiress whose future is being decided by more powerful men. Further fictional perspectives on Robert, 1st Earl of Gloucester can be found in Elizabeth Chadwick’s The Love Knot, Sharon Kay Penman’s When Christ and His Saints Slept, Elizabeth Chadwick’s A Place Beyond Courage, Ellis Peters’ An Excellent Mystery, and Elizabeth Chadwick’s Lady of the English.
