Louis persisted in struggling for the preponderance of the crown against the great vassals; succeeded in taming Peter Mauclerc, the turbulent Count of Brittany; wrung from Theobald IV., Count of Champagne, the rights of suzerainty in the countships of Chartres, Blois, and Sancerre, and the viscountship of Chateaudun, and purchased the fertile countship of Macon from its possessor.
