Blois is strategically located between two hills on the right bank of the Loire. It is the capital of Loir-et-Cher in the former French provinvce Orléanais.
Blois is first mentioned as Blesae by Gregory of Tours in his History of the Franks In the tenth century it became a county capital. The influential counts of Blois, descended from Hugo Capet, held two important regions: The region of Blois and Chartres, and the distant Champagne. Despite repeated attacks by their neighbours and rivals, the counts of Anjou , they managed to found a powerful dynasty.
In 1392 the last count, Guy de Châtillon, who had had no children, sold the county to Louis I of Orleans, the brother of King Charles VI. After that the French court was held at Blois until some time after 1594 Henry IV brought it back to Paris.
