Stephen (born c. 1097—died Oct. 25, 1154, Dover, Kent, Eng.) was the king of England from 1135 to 1154. He gained the throne by usurpation but failed to consolidate his power during the ensuing civil strife.
Stephen was the third son of Stephen, Count of Blois and Chartres, and Adela, daughter of King William I the Conqueror. He was reared by his uncle, King Henry I, and received vast lands in England, Normandy, and the county of Boulogne. With a number of other magnates he was pledged to support Henry’s daughter, Matilda (q.v.), as successor to the throne. Nevertheless, many English nobles were reluctant to accept a woman ruler, and Henry’s Norman subjects resented Matilda’s marriage into an Angevin family. Consequently, after Henry I died in December 1135, the leading lords and bishops welcomed Stephen when he crossed the English Channel to claim the crown. In return for support from the pope, Stephen opened the way to increased papal influence in English political affairs.
Although Stephen was brave and energetic, his affable, mild-mannered nature prevented him from providing firm leadership. The lawlessness of his Flemish mercenaries and the desperate measures he took to build a party loyal to himself only alienated the barons. Hence, in 1138 Matilda’s half brother, the powerful Robert, Earl of Gloucester, took up arms in support of Matilda’s claim. At first Stephen scored several military triumphs, but he lost the support of the church when he arrested Bishop Roger of Salisbury and his relatives.
Seizing her opportunity, Matilda invaded England (September 1139). In an incredible display of chivalry, Stephen had Matilda escorted to Bristol, and she proceeded to bring most of western England under her control. Early in 1141 the Angevins captured Stephen in a battle at Lincoln. His cause might have been lost had not Matilda’s arrogance provoked a rebellion of the citizens of London, where she had gone for her coronation. In November Stephen was exchanged for Gloucester, who had been captured by forces loyal to the king. Stephen gradually gained the upper hand, and in 1148 Matilda withdrew from England.
Although Stephen at this point exercised nominal control over most of the kingdom, he had neither the resources nor the will to suppress lawlessness and to mediate between warring nobles. He hoped only to secure the succession for his son, Eustace, but to do so he had to deal with Matilda’s son, Henry of Anjou, who invaded England in January 1153 to claim his royal inheritance. When Eustace died in August, Stephen lost heart; he signed a treaty designating Henry as his successor. At Stephen’s death, Henry ascended the throne as King Henry II.
