THEOBALD OF CHAMPAGNE
Theobald II, Count of Blois, Meaux and Champagne, was one of the most powerful nobles in France, and by the extent of his influence fully deserved the title of "the Great" by which he was subsequently known. His domain included the modern departments of Ardennes, Marne, Aube and Haute-Marne, with part of Aisne, Seine-et-Marne, Yonne and Meuse. Furthermore, his mother Adela, was the daughter of William I of England, and his younger brother, Stephen, was King of England from 1135 to 1154. Theobald became Count of Blois in 1102, Count of Champagne in 1125, and Count of Troyes in 1128. Had he so chosen, he might likewise have become Duke of Normandy after the death of his uncle, Henry I of England, in 1135. He died in 1152.
