Founder of the Roman Catholic Dominican order of preaching friars. Feast day 7 Aug. Born in Old Castile, Dominic was sent by Pope Innocent III in 1205 to preach among the heretic Albigenesian sect in Provence. In 1208 the pope instigated the Albigensian crusade to suppress the heretics by force, and this was supported by Dominic. In 1215 the Dominican order was given premises at Toulouse; during the following years Dominic established friaries at Bologna and elsewhere in Italy, and by the time of his death the order was established all over W Europe.
