 La Bastide-l'Évêque appears as "la Baftide l'Evesque" on the 1750 Cassini Map and does not appear at all on the 1790 version although the hamlet of "Cadour" does.Founded in 1280 by Bishop Raymond de Calmont, La Bastide l'Évêque is one of the five Bastides in western Rouergue with Najac, Sauveterre-de-Rouergue, Villeneuve d'Aveyron, and Villefranche-de-Rouergue.This was the foundation of the Diocese of Rodez on the remains of "Morlhon" and "Faidits" to counter the county bastide of "Villafranca" (Villefranche-de-Rouergue) to limit its population, influence, and development.
