Name: Theobald I "the Cheater" De BLOIS
Name: Theobald I "Le Tricheur" Count of Blois
Birth: ABT 913 in Blois, France
Theobald I (died 16 January between 975 and 978), called the Cheater, was the first count of Blois, Chartres, and Châteaudun from 960, and Tours from 945. He was originally viscount of Tours from 928. He was the son and successor of Theobald the Old and Richilde, the widow of King Charles the Simple.
Theobald was initially a vassal of Hugh the Great, Duke of France. Around 945, he catpured King Louis IV to the benefit of Hugh. In return for freedom, the king granted him the city of Laon. He took the title of "count" in Tours. He seized Chartres and Châteaudun and remarried his sister to Fulk II of Anjou. In 958, he met Fulk in Verron and the two described themselves as "governor and administrator [of the] kingdom [of Neustria]" and comites Dei gratia ("counts by the grace of God").
Theobald's sister married Alan II of Brittany and Theobald governed the duchy during the minority of her son Drogo. Thus, Theobald extended his influence all the way to Rennes.
In 960, he began opposing Richard I of Normandy and entered into a long war with the Normans. In 961, he attacked Évreux. The Normans responded by attacking Dunois. In 962, he launched an assault on Rouen which failed. The Normans burned Chartres in response. He took control of the fortresses of Saint-Aignan-sur-Cher, Vierzon, and Anguillon in Berry.
During the minority of Hugh Capet, he reinforced Chartres and Châteaudun. Around 960, he built Saumur. By his death, he had built a vast power on the Loire, dominating central France. By his wife Luitgarde of Vermandois, widow of William I of Normandy, married between 942 and 945, he had four children.
His daughter brought him the county of Provins, nucleus of the later county of Champagne.
