Stephen was King of England from December 1135 to his death. He was Count of Boulogne 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. He was born in the County of Blois in central France; his father, Count Stephen-Henry, died while Stephen was still young, and he was brought up by his mother, Adela, daughter of William the Conqueror. 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.   WIkipedia article.
