Inherits Blois

Upon his father's death in 1037, Theobald inherited amongst others the counties of Blois,[1] Tours, Chartres. Châteaudun and Sancerre, and also in Champagne: Château-Thierry, Provins and St. Florentin. His brother Stephen inherited the counties of Meaux, Troyes and Vitry-le-François. By 1044, Geoffrey Martel, the Count of Anjou, was besieging Tours and Theobald responded by attempting to relieve the city.[3] They met in battle at Nouy and Theobald was captured and had to give up the county of Touraine in order to regain his freedom.[3] From then on the centre of power for the House of Blois moved to Champagne.

In 1054, Theobald recognized the Holy Roman Emperor, Henry III as his liege which precipitated a meeting at Ivois between Henry I and the emperor.[4] Theobald found ways to become close to the royal court again and gained political influence and began calling himself, Count Palatine.[1]

Gains Champagne

Theobald's nephew, Odo, Count of Champagne joined the army of William the Conqueror and participated in the Norman conquest of England. Theobald used his nephew's absence and his own influence at court to gain control over Odo's possessions in Champagne.[1] He had gained a position of considerable power, which increased when he married the daughter of Ralph IV of Valois. From 1074 onward, he left his son Henry in control of Blois, Châteaudun and Chartres.


Following Theobald's death in 1089, Philip I, King of France, was able to arrange for Blois and Champagne to be divided between Theobald's sons.[1]
