Overview

Comté de Blois; capital Blois. A county of the middle Loire held by the powerful House of Blois-Champagne, which at its height under Odo/Eudes II (d. 1037) menaced the Capetians and held Champagne as well. Members became kings of England (Stephen) and Navarre. Blois passed to the House of Châtillon and then, by sale, to Louis of Orléans (1391), becoming an Orléanist possession and ultimately merging into the crown lands.
