Roman Catholic Archdiocese of Eauze

The former Roman Catholic Metropolitan Archdiocese of Eauze (Latin Elusa), in Aquitaine, south-west France, existed from circa 300 to 879.

Its Ancient cathedral was so utterly destroyed it hasn't even been located. The present Éauze Cathedral, dedicated to St. Luperculus, was built around 500 and became co-cathedral of the successor see Archdiocese of Auch in 1864.

Elusa, capital of the Gallic Late Roman province of Novempopulania since Emperor Diocletian split if off from Gallia Aquitania, was also made its Metropolitan Archbishopric, plausibly soon after. Eauze remained known as Elusa in the early Middle Ages.

Its suffragan sees were, as attested in 506 at a council in Agde : Diocese of Auch, Diocese of Aire, Diocese of Bazas, Diocese of Dax, Diocese of Comminges, Diocese of Couserans, Diocese of Lectoure, Diocese of Lescar, Diocese of Oloron and Diocese of Tarbes. It 551 the Metropolitan hosted a synod in Euze attended by eight of his suffragans.
