for many years with neither side able to win an advantage. Stephen became increasingly concerned with ensuring that his son Eustace would inherit his throne. The King tried to convince the church to agree to crown Eustace to reinforce his claim; Pope Eugene III refused, and Stephen found himself in a sequence of increasingly bitter arguments with his senior clergy. In 1153, the Empress's son Henry invaded England and built an alliance of powerful regional barons to support his claim for the throne. The two armies met at Wallingford, but neither side's barons were keen to fight another pitched battle. Stephen began to examine a negotiated peace, a process hastened by the sudden death of Eustace. Later in the year Stephen and Henry agreed to the Treaty of Winchester, in which Stephen recognised Henry as his heir in exchange for peace, passing over William, Stephen's second son. Stephen died the following year. Modern historians have extensively debated the extent to which his personality, external events, or the weaknesses in the Norman state contributed to this prolonged period of civil war. Early life (1097–1135) Childhood Stephen was born in Blois, France, in either 1092 or 1096. His father was Stephen-Henry, Count of Blois and Chartres, an important French nobleman, and an active crusader, who played only a brief part in Stephen's early life. During the First Crusade, Stephen-Henry had acquired a reputation for cowardice, and he returned to the Levant again in 1101 to rebuild his reputation; there he was killed at the battle of Ramlah. Stephen's mother, Adela, was the daughter of William the Conqueror and Matilda of Flanders, famous amongst her contemporaries for her piety, wealth and political talent. She had a strong matriarchal influence on Stephen during his early years. France in the 12th century was a loose collection of counties and smaller polities, under the minimal control of the King of France. The King's power was linked to his control of the rich province of Île-de-France, just to the east of Stephen's home county of Blois. In the west lay the three counties of Maine, Anjou and Touraine, and to the north of Blois was the Duchy of Normandy, from which William the Conqueror had conquered England in 1066. William's children were still fighting over the collective Anglo-Norman inheritance. The rulers across this region spoke a similar language, albeit with regional dialects, followed the same religion, and
