   General Notes:

Comte de Chartres, de Châteaudun, de Meaux, de Sancerre et de Troyes


Theobald inherited amongst others the counties of Blois, Tours, Chartres. Chateaudun and Sancerre, and also in Champagne: Chateau-Thierry, Provins and St. Florentin. His brother Stephen inherited the counties of Meaux, Troyes and Vitry.

Theobald conspired against the king of France Henry I, was beaten in 1044 and had to give up the county of Tours to regain his freedom. From then on the centre of power for the House of Blois moved to Champagne. Theobald found ways to become close to the royal court again and gain infuence. He got the title of Count Palatine, which his father had used before. He used this influence to get control over his brother's possessions in Champagne that were inherited by his minor nephew Odo III. Odo later joined the army of William the Conqueror, participated in the battle of Hastings, married a sister of William and became count of Aumale and Holderness.

Theobald had a position of considerable power, that increased when he married the daughter of Raoul de Valois. From 1074 onward, he left his son Henry in control of Blois, Chateaudun and Chartres.
