Dominic de Guzmán

Life and work

Dominic was born in Castile and became a canon regular before accompanying his bishop on a diplomatic journey through southern France, where he encountered the Cathar (Albigensian) heresy, a dualist movement that rejected the material world and much of orthodox Catholic sacramental practice.

Convinced that heresy needed to be met with better preaching and a visible model of apostolic poverty rather than force alone, Dominic began preaching missions in Languedoc and in 1216 received papal approval from Honorius III for a new order dedicated to preaching and study, the Order of Preachers.

Unlike earlier monastic orders bound to a single location, Dominicans were organized as a mobile, educated preaching order that would send friars to universities and cities across Europe, producing some of the era's greatest scholars, including Thomas Aquinas a generation later.

Dominic's own order later became closely associated, controversially, with the medieval Inquisition established to investigate heresy, though this development occurred mainly after his death and reflected broader ecclesiastical and political structures of the thirteenth century rather than a specific mandate from Dominic himself.
