Original: In an effort to colonize the wilderness especially of southwest France, almost seven hundred new towns were built between 1222 (Cordes-sur-Ciel, Tarn) and 1372 (La Bastide d'Anjou, Tarn).
Simplified: Bastides were built mainly between 1229 and 1373, between the Albigensian Crusade and the Hundred Years War.
