Geoffrey de Mandeville, 1st Earl of Essex (d. 1144) was one of the prominent players during the Anarchy of the reign of King Stephen of England. His biographer, the 19th-century historian J. H. Round, called him "the most perfect and typical presentment of the feudal and anarchic spirit that stamps the reign of Stephen." The Anarchy in English history commonly names the period of civil war and unsettled government that occurred during the reign (1135–1154) of King Stephen of England. ... Stephen (1096 – October 25, 1154), the last Norman King of England, reigned from 1135 to 1154, when he was succeeded by his cousin Henry II, the first of the Angevin or Plantagenet Kings. ...

He succeeded his father, William sometime before 1130. A key portion of the family patrimony was in the king's hands, as William had incurred Henry I's displeasure and lost them, along with his office as constable of the Tower of London. The king also held the substantial estate of Geoffrey's maternal grandfather Eudo Dapifer. William de Mandeville was the name of two important barons in medieval England, who were grandfather and grandson. ... King Henry I of England (c. ...

Geoffrey's goal in the early years of strife between Stephen and Maud seems to have been to recover these lost lands. He succeeded in this, during the shifting tides of fortunes of the two competitors for the English throne, by bidding his support to first one, then the other. Stephen (1096 – October 25, 1154), the last Norman King of England, reigned from 1135 to 1154, when he was succeeded by his cousin Henry II, the first of the Angevin or Plantagenet Kings. ...

He started out supporting Stephen, who sometime in 1140 (or perhaps December 1139) made him Earl of Essex in reward for his services against Maud. In 1140 or 1141 Stephen returned to him the seized estates in Essex. In 1141 he was also appointed custodian of the Tower of London. Earl of Essex is a title that has been held by several families and individuals, of which the best-known and most closely associated with the title was Robert Devereux, 2nd Earl of Essex (1566 - 1601). ...

After the defeat and capture of Stephen at Lincoln (1141) the earl, like many barons, acknowledged Maud as his sovereign lady. She confirmed his custody of the Tower, forgave the large debts his father had incurred to the crown, granted him the Norman lands of Eudo Dapifer, and appointed him sheriff of Essex, Middlesex and London, and Hertfordshire. But before the end of the year, learning that Stephen's release was imminent, he returned to his original allegiance. In 1142 he may have been intriguing with the empress; he rebelled when he was deprived of his castles by the king in 1143.

In 1143-1144 Geoffrey maintained himself as a rebel and a bandit in the fen-country, using the Isle of Ely and Ramsey Abbey as his headquarters. He was besieged by Stephen in the fens, and met his death in September 1144 in consequence of an arrow wound received in a skirmish.

His career is interesting for two reasons. The charters which he received from Stephen and Matilda illustrate the peculiar form taken by the ambitions of English feudatories. The most important concessions are grants of offices and jurisdictions which had the effect of making Mandeville almost a viceroy with full powers in Essex, Middlesex and London, and Hertfordshire--but these were based on offices and jurisdictions his ancestors had held. His career as an outlaw exemplifies the worst excesses of the Anarchy which prevailed in some parts of England during the civil wars of 1140-1147, and it is probable that the deeds of Mandeville inspired the rhetorical description, in the Peterborough Chronicle of this period, when "men said openly that Christ and his saints were asleep." Empress Matilda (February, 1101 – September 10, 1167) (Saxon form Maud or Maude) – was the daughter and dispossessed heir of King Henry I of England. ...
