Robert FitzRoy, 1st Earl of Gloucester (c. 1090 – 31 October 1147), was an illegitimate son of King Henry I. He was the half-brother of the Empress Matilda, and her chief military supporter during the civil war known as the Anarchy, in which she vied with Stephen of Blois for the throne of England.

Early life
Robert was probably the eldest of Henry's many illegitimate children. He was born before his father's accession to the English throne, either during the reign of his grandfather William the Conqueror or his uncle William Rufus. He is sometimes and erroneously designated as a son of Nest, daughter of Rhys ap Tewdwr, last king of Deheubarth, although his mother has been identified as a member of "the Gay or Gayt family of north Oxfordshire", possibly a daughter of Rainald or Reginald Gay (fl. 1086) of Hampton Gay and Northbrook Gay in Oxfordshire. Rainald had known issue, Robert Gay of Hampton (died c. 1138) and Stephen Gay of Northbrook (died after 1154). A number of Oxfordshire women feature as the mothers of Robert's siblings.
Robert may have been a native of Caen or he may have been only the constable and governor of that city, jure uxoris.
Robert's father had contracted him in marriage to Mabel FitzRobert, daughter and heir of Robert Fitzhamon, but the marriage was not solemnised until June 1119 at Lisieux. His wife brought him the substantial honours of Gloucester in England and Glamorgan in Wales, and the honours of Sainte-Scolasse-sur-Sarthe and Évrecy in Normandy, as well as Creully and Thorigny. After the White Ship disaster late in 1120, and probably because of this marriage, in 1121 or 1122 his father created him Earl of Gloucester. He commissioned the translation of Welsh historical sources which the subject lent to Walter Espec of Helmsley, and he, in turn, lent to others.
Earl of Gloucester
In either 1121 or 1122, his father created him the 1st Earl of Gloucester. Robert became powerful in both the countries of Normandy and England with this act, as Caen may have remained his principal seat.
Robert possessed many castles and land through grants made to him by his father, King Henry. He was the keeper of Gloucester Castle, Canterbury Castle and fortresses of Bristol, Leeds and Dover. Bristol Castle was Robert's principal seat in England and he constructed additions to its exterior fortifications and rebuilt the interior. Robert held Gloucester Castle in right of his earldom, however, after Miles of Gloucester, 1st Earl of Hereford was created earl, Miles became the constable of it under Robert, his liege-lord, as Florence of Worcester called him.
There is evidence in the contemporary source, the Gesta Stephani, that Robert was proposed by some as a candidate for the throne, after his father's death, but his illegitimacy ruled him out:
Among others came Robert, Earl of Gloucester, son of King Henry, but a bastard, a man of proved talent and admirable wisdom. When he was advised, as the story went, to claim the throne on his father's death, deterred by sounder advice he by no means assented, saying it was fairer to yield it to his sister's son (the future Henry II of England), than presumptuously to arrogate it to himself.
This suggestion cannot have led to any idea that he and Stephen were rivals for the Crown, as Geoffrey of Monmouth in 1136 referred to Robert as one of the 'pillars' of the new King's rule.
For the first five years after the death of his father, Henry I, and usurpation of power by Stephen in 1135, Robert seems to have been an inactive spectator of the struggle between Stephen and Matilda.
In June 1138, Geoffrey Plantagenet, Count of Anjou persuaded Robert to join the party opposing King Stephen through prayers and promises given to Robert when Geoffrey entered Normandy. It is said that when the hostilities first began, Robert acted with "great prudence, and still held aloof," but that his hostility to Stephen was not disguised. Thus, while Robert sided in June 1138 with the party opposing Stephen's rule was a great change in the power dynamics in England, it may not have been quite as unexpected as some scholars make it out to be, as "his hostility to Stephen was scarcely disguised."

Robert and his wife Mabel Fitzhamon married in 1119, and they had seven children:

In popular culture
Robert of Gloucester is a figure in many of the novels by Ellis Peters in The Cadfael Chronicles (written between 1977 and 1994) where he is seen as a strong moderating force to his half-sister (see Saint Peter's Fair). His efforts to gain the crown for his sister by capturing King Stephen and her own actions in London are part of the plot in The Pilgrim of Hate. His capture by Stephen's wife Queen Mathilda is in the background of the plot of An Excellent Mystery. The exchange of the imprisoned Robert for the imprisoned Stephen is in the background of the plot of The Raven in the Foregate. Robert's travels to persuade his brother-in-law to aid Empress Maud militarily in England is in the background of the novel The Rose Rent. His return to England when Empress Maud is trapped in Oxford Castle figures in The Hermit of Eyton Forest.
Robert's return to England with his young nephew Henry, years later the king succeeding Stephen, is in the background of the plot of The Confession of Brother Haluin, as the battles begin anew with Robert's military guidance. Robert's success in the Battle of Wilton leads to the death of a fictional character, part of the plot of The Potter's Field. In the last novel, he is a father who can disagree with and then forgive his son Philip (see the last novel, Brother Cadfael's Penance). In that last novel, Brother Cadfael speculates on the possibly different path for England if the first son of old King Henry, the illegitimate Robert of Gloucester, had been recognised and accepted. In Wales of that era, a son was not illegitimate if recognised by his father, and to many in the novels, Robert of Gloucester seemed the best of the contenders to succeed his father.
Robert is also a central character in Sharon Penman's 1995 novel When Christ and His Saints Slept. He was also central in the struggle during the Anarchy as portrayed in Ken Follett's 1989 novel The Pillars of the Earth, in the 2010 mini-series, and in the 2017 video game of the same name too.
