Count of Blois

The County of Blois was centred on Blois, south of Paris. One of the chief cities, along with Blois itself, was Chartres. Blois was associated with Champagne, Châtillon (the lords of which tended to reside in Blois), and later with the French royal family, to whom the county passed in 1391. Blois was later important during the Hundred Years' War; Joan of Arc based herself there.
