Throughout the ninth century the Vikings had made a concerted effort to conquer and rule all of Anglo-Saxon England. Because of its proximity to Scandinavia and its lack of unity under a single ruler, England probably suffered more from Viking invasions than any other part of Europe. In 878 Alfred, king of the West Saxons (or Wessex), defeated the Vikings, inaugurating a period of recovery and stability in England. Alfred and his immediate successors built a system of local defenses and slowly extended royal rule beyond Wessex to other Anglo-Saxon peoples until one law, royal law, took precedence over local custom. England was divided into local units called shires, or counties, each under the jurisdiction of a shire-reeve (a word that soon evolved into sheriff ) appointed by the king. Sheriffs were unpaid officials from well-off families responsible for collecting taxes, catching and trying criminals, and raising infantry when the king required it.

The Viking invasions of England resumed, however, and the island eventually came under Viking rule. The Viking Canute (r. 1016–1035) made England the center of his empire while promoting a policy of assimilation and reconciliation between Anglo-Saxons and Vikings. When Canute’s heir Edward died childless, there were three claimants to the throne of England — the Anglo-Saxon noble Harold Godwinson (ca. 1022–1066), who had been crowned by English nobles; the Norwegian king Harald III (r. 1045–1066), grandson of Canute; and Duke William of Normandy, who was the illegitimate son of Edward’s cousin.

In 1066 the forces of Harold Godwinson crushed Harald’s invading army in northern England, then quickly marched south when they heard that William had invaded England with his Norman vassals. Harold was decisively defeated by William at the Battle of Hastings — an event now known as the Norman conquest. In both England and Normandy, William the Conqueror limited the power of the nobles and church officials, and built a unified monarchy. In England he retained the office of sheriffs, but named Normans to the posts. William wanted to determine how much wealth there was in his new kingdom and who held what land. Royal officials were sent to every part of the country, and in every village local men were put under oath to answer the questions of these officials. In the words of a contemporary chronicler:

The resulting record, called the Domesday Book (DOOMZ-day) from the Anglo-Saxon word doom, meaning “judgment,” helped William and his descendants tax land appropriately. The book still survives and is an invaluable source of social and economic information about medieval England. It also helped William and future English kings regard their country as one unit.

William’s son Henry I (r. 1100–1135) established a bureau of finance called the Exchequer that became the first institution of the government bureaucracy of England. In addition to various taxes and annual gifts, Henry’s income came from money paid to the Crown for settling disputes and as penalties for crimes, as well as money due to him in his private position as landowner and lord. Henry, like other medieval kings, made no distinction between his private income and state revenues, and the officials of the Exchequer began to keep careful records of all monies paid into and out of the royal treasury. (See “Primary Source 9.1: Marriage and Wardship in the Norman Exchequer.”)

In 1128 Henry’s daughter Matilda was married to Geoffrey of Anjou; their son became Henry II of England and inaugurated the Angevin (AN-juh-vuhn; from Anjou, his father’s county) dynasty. Henry II inherited the French provinces of Anjou, Normandy, Maine, and Touraine in northwestern France, and in 1152 he married Eleanor of Aquitaine, heir to Aquitaine, Poitou (pwah-TOO), and Gascony in southwestern France. As a result, Henry claimed nearly half of today’s France, and the histories of England and France became closely intertwined, leading to disputes and conflicts down to the fifteenth century.
