Stephen (1092 or 1096 – 25 October 1154), often referred to as Stephen of Blois, was King of England from 22 December 1135 to his death in 1154. He was Count of Boulogne jure uxoris from 1125 until 1147 and Duke of Normandy from 1135 until 1144. His reign was marked by the Anarchy, a civil war with his cousin and rival, the Empress Matilda, whose son, Henry II, succeeded Stephen as the first of the Angevin kings of England.
Stephen was born in the County of Blois in central France as the fourth son of Stephen-Henry, Count of Blois, and Adela, daughter of William the Conqueror. His father died while Stephen was still young, and he was brought up by his mother. Placed into the court of his uncle Henry I of England, Stephen rose in prominence and was granted extensive lands. He married Matilda of Boulogne, inheriting additional estates in Kent and Boulogne that made the couple one of the wealthiest in England. Stephen narrowly escaped drowning with Henry I's son, William Adelin, in the sinking of the White Ship in 1120; William's death left the succession of the English throne open to challenge. When Henry died in 1135, Stephen quickly crossed the English Channel and, with the help of his brother Henry, Bishop of Winchester and Abbot of Glastonbury, took the throne, arguing that the preservation of order across the kingdom took priority over his earlier oaths to support the claim of Henry I's daughter, the Empress Matilda.
