William the Conqueror

Historical Background

The reign of William the Conqueror (1035-1087) traditionally appears as a prosperous period for the duchy of Normandy.

Despite the difficult start where the young Duke has to face opposition from a part of the Norman aristocracy, peace is essential in the duchy and the ducal power is reinforced.

William grows his ancestors’ past alliances and develops new ones, imposing himself as a territorial prince with international reputation.

In 1066 , he is officially crowned king of England,  December 25 in Westminster Abbey,  based upon a long-standing Anglo-Norman marriage alliance.
William is one of those sea princes of 11th century, as the Danish King Knut the Great, who, revisiting the legacy of their Viking ancestors in a more political perspective, succeeds with a powerful fleet to conquer an empire and to keep it, attempting to develop institutions and a strong administrative apparatus.


In 1085, he ordered the creation of a large inventory of territories and possessions of each lord in England : the Domesday Book, manuscript comprising two volumes: Great Domesday (general account of British territories except Suffolk, Norfolk and Essex ) and Little Domesday (general account territories of Norfolk , Suffolk and Essex), whose goal is to identify for future taxes, record tenures (and their changes) after 19 years of Norman rules and to solve conflicts by the recognition of acquired land.

In July 1087, Guillaume attacked the territory of Vexin, was wounded in the battle and brought back dying to Rouen.

He made donations to churches, appointed his eldest son Robert, his successor at the head of the Duchy of Normandy and gave William, his second son, England without naming him king directly. Finally he gave his third son Henry money.

William died September 9, 1087. He is buried at Caen in the Abbaye-aux-Hommes and his wife Matilda in the Abbaye-aux-Dames in 1083 .
