William Clito, Count of Flanders

William Clito was born on 25 October 1102 in Rouen, Caux, Normandy, as a member of the House of Normandy. He was the son of Robert Curthose, the eldest son of William the Conqueror, and Sibylla of Conversano. His early life involved being placed in the custody of Helias of Saint Saens after his father was captured by King Henry I of England.

William Clito's claim to the Duchy of Normandy was a central aspect of his life, as he was seen as a potential successor to his uncle, King Henry I of England. However, Henry viewed him as a rival, leading William to ally with King Louis VI of France. This alliance resulted in William being installed as the Count of Flanders after the assassination of Charles the Good.

William's tenure as Count of Flanders involved dealing with multiple claimants to the title. He initially captured William of Ypres, but his rule was challenged by revolts and rival claimants supported by King Henry I. His marriage to Sibylla of Anjou was annulled in 1124, affecting his political alliances.

In 1127, William Clito married Joanna of Montferrat, strengthening his ties with King Louis VI. His rule in Flanders faced instability due to internal revolts and external pressures. He encountered opposition from Thierry of Alsace and other claimants.

William Clito's military campaigns in Flanders included a victory at the Battle of Axspoele, where he ambushed Thierry's forces. His position remained precarious, and he continued to face challenges from rival factions. His efforts to secure his rule were supported by allies such as Count Godfrey I of Louvain.

During a siege at Aalst in July 1128, William Clito was wounded in the arm, leading to a gangrenous infection. Despite the care of his brother-in-law, Helias of Saint-Saëns, William succumbed to his injuries on 28 July 1128. His body was buried at the Abbey of Saint Bertin in Flanders.

William Clito died at the age of 25, and his death marked the end of his reign as Count of Flanders. He was succeeded by Thierry of Alsace, who became the new count.
