Ancient Diocese of Lavaur
ancient Catholic diocese in France

The bishopric of Lavaur (Tarn, France) (in Latin: dioecesis Vaurensis) was founded by Pope John XXII in his plan to reorganize the sprawling diocese of Toulouse. The town is situated some fifteen miles to the east of Toulouse. Lavaur had the reputation of being one of the strongest centers of Catharism, being referred to as sedes Satanae, atque erroris haeretici primatica ('seat of Satan and prime source of heretical error' The diocese consisted of some 80–90 parishes. It hosted one abbey, that of Sorèz, a convent of the Clarisses, a convent of the Daughters of the Cross, a convent of Dominicans, one of Franciscans, one of Capuchins, two of reformed Dominicans, and two houses of the Doctrinaires. The diocese produced some 35,000 livres for the bishop.
The diocese was abolished by the Concordat of 1801.
History
The diocese had its primitive origins in a donation made in 1098 by three sons of Guillaume Seigneur of the chateau of Lavaur, one of whom was Isarn, the Bishop of Toulouse. They gave to the monks of Saint-Pons the church of Saint-Élan (Alain) in the territory of Toulouse, not far from their chateau, on the left bank of the River Agoût; the church was in need of rebuilding; the mission of the monks was to rebuild the church, around which grew a small town (villa). During the Albigensian Crusade the town, which was politically in the County of Toulouse and subject to the heretic Count Raymond of Toulouse, was besieged. The town was fortified in the 13th century.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
