King Louis VII of France became involved in a war with Theobald by permitting Rodolphe, Count of Vermandois and seneschal of France, to repudiate his wife, Theobald's niece, and to marry Petronille of Aquitaine, sister of the queen of France. The war, which lasted two years (1142-1144), was marked by the occupation of Champagne by the royal army and the capture of Vitry, where many persons perished in the burning of the church.
Pierre Abélard sought asylum in Champagne during Theobald II's reign.
Formed at random by the acquisitions of the counts of the houses of Vermandois and Blois, Champagne reckoned among its dependencies, from 1152 to 1234, the countship of Blois and Chartres, of which Touraine was a fief, the countship of Sancerre, and various scattered fiefs in the Bourbonnais and in Burgundy.
After Theobald the Great the countship of Blois ceased to be the dominant fief of his house and became the appanage of a younger branch.
In 1197 Theobald III., younger son of Henry I., became count, and was succeeded in 1201 by Theobald IV., "le Chansonnier" (the singer), who was the son of Theobald III.
TheobaldII of Champagne (1090-1151), also known as Theobald The Great, was Count of Champagne from 1125 to 1151, as well as count of Blois and of Chartres (from 1102).
He was the son of Stephen II, Count of Blois and Adela of Normandy, and the elder brother of King Stephen of England.
