Matilda of Flanders, wife of William the Conqueror, is crowned Queen of England.

Matilda of Flanders was Queen of England and Duchess of Normandy by marriage to William the Conqueror, and regent of Normandy during his absences from the duchy. She was the mother of nine children who survived to adulthood, including two kings, William II and Henry I.

William the Conqueror, sometimes called William the Bastard, was the first Norman king of England, reigning from 1066 until his death. A descendant of Rollo, he was Duke of Normandy from 1035 onward. By 1060, following a long struggle, his hold on Normandy was secure. In 1066, following the death of Edward the Confessor, William invaded England, leading a Franco-Norman army to victory over the Anglo-Saxon forces of Harold Godwinson at the Battle of Hastings, and suppressed subsequent English revolts in what has become known as the Norman Conquest. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands, and by difficulties with his eldest son, Robert Curthose.

The English royal consorts listed here were the spouses of the reigning monarchs of the Kingdom of England, excluding joint rulers William III and Mary II who reigned together in the 17th century.
