Matilda of Flanders (; ; German: Mechtild) ( 1031 – 2 November 1083) 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.

In 1031, Matilda was born into the House of Flanders, the only daughter of Count Baldwin V of Flanders and Adela of France. Flanders was of strategic importance to England and most of Europe as a "stepping stone between England and the Continent" necessary for strategic trade and for keeping the Scandinavian Intruders from England. In addition, her mother was the daughter of Robert II of France. For these reasons, Matilda was of grander birth than William, who was illegitimate, and, according to some more romantic tellings of the story, she initially refused his proposal on this account. Her descent from the Anglo-Saxon royal House of Wessex was also to become a useful card. Like many royal marriages of the period, it breached the rules of consanguinity, then at their most restrictive (to seven generations or degrees of relatedness); Matilda and William were third-cousins once removed. She was about 20 when they married in 1051/2; William was some four years older, and had been Duke of Normandy since he was about eight (in 1035).

The marriage appears to have been successful, and William is not recorded to have had any bastards. Matilda was about 35, and had already borne all but two of her children, when William embarked on the Norman conquest of England, sailing in his flagship Mora, which Matilda had given him. She governed the Duchy of Normandy in his absence, joining him in England after more than a year, to be crowned in an elaborate ceremony. She subsequently returned to Normandy, but crossed to England repeatedly, and ruled England in William's absence between the years 1081 and 1083. Matilda also regularly served as regent in Normandy. She was about 52 when she died in Normandy in 1083.

Matilda of Flanders

Apart from governing Normandy and supporting her brother's interests in Flanders, Matilda took a close interest in the education of her children, who were unusually well educated for contemporary royalty. The boys were tutored by the Italian Lanfranc, who was made Archbishop of Canterbury in 1070, while the girls learned Latin in Sainte-Trinité Abbey in Caen, founded by William and Matilda as part of the papal dispensation allowing their marriage.

Rumours of romances

There were rumours that Matilda had been in love with the English ambassador to Flanders and with the great Anglo-Saxon thegn Brictric, son of Algar, who (according to the account by the Continuator of Wace and others) in his youth declined her advances. Whatever the truth of the matter, years later she is said to have used her authority to confiscate Brictric's lands and throw him into prison, where he died.

Marriage

Matilda, or Maud, was the daughter of Baldwin V, Count of Flanders, and Adela, herself daughter of King Robert II of France.

According to legend, when the Norman duke William the Bastard (later called the Conqueror) sent his representative to ask for Matilda's hand in marriage, she told the representative that she was far too high-born to consider marrying a bastard. After hearing this response, William rode from Normandy to Bruges, found Matilda on her way to church, dragged her off her horse by her long braids, threw her down in the street in front of her flabbergasted attendants and rode off. Some narrations of this event also state that William rolled Matilda in the mud and badly beat her before galloping away.

Another version of the story states that William rode to Matilda's father's house in Lille, threw her to the ground in her room (again, by her braids) and hit her (or violently battered her) before leaving. Naturally, Baldwin took offence at this; but, before they could draw swords, Matilda settled the matter by refusing to marry anyone but William; even a papal ban by Pope Leo IX at the Council of Reims on the grounds of consanguinity did not dissuade her. William and Matilda were married after a delay in . A papal dispensation was finally awarded in 1059 by Pope Nicholas II. Lanfranc, at the time prior of Bec Abbey, negotiated the arrangement in Rome and it came only after William and Matilda agreed to found two churches as penance.
