“ ALBIGENSES, the usual designation of the heretics—and more especially the Catharist heretics—of the south of France in the 12th and 13th centuries. This name appears to have been given to them at the end of the 12th century, and was used in 1181 by the chronicler Geoffroy de Vigeois. The designation is hardly exact, for the heretical centre was at Toulouse and in the neighbouring districts rather than at Albi (the ancient Albiga) . The heresy, which had penetrated into these regions probably by trade routes, came originally from eastern Europe. ”
