Theobald II of Champagne

Theobald the Great (1090–10 January 1152) was the son of Count Stephen-Henry of Blois and Adela of Normandy, and brother of King Stephen of England. He succeeded to Blois and Chartres in 1102. In 1123 he married Matilda of Carinthia; their children included Henry I of Champagne and Adela, wife of King Louis VII. When his uncle Hugh abdicated in 1125, Theobald added Champagne and Brie, reuniting the family lands.

War over his sister Eleanor's marriage in 1142–1144 saw royal troops burn Vitry-en-Perthois, where hundreds died in the burning church. Theobald died on 10 January 1152.
