Dioecesis Septem Provinciarum
Diocese of the Seven ProvincesDiocese of the Roman Empire 314–477 Capital Burdigala Historical era Late Antiquity - Established 314 - Fall of the Provence to the Visigoths 477 The Diocese of the Seven Provinces (Latin: Dioecesis Septem Provinciarum), originally called the Diocese of Vienne (Latin: Dioecesis Viennensis) after the city of Vienna (modern Vienne), was a diocese of the later Roman Empire, under the praetorian prefecture of Gaul. It encompassed southern and western Gaul (Aquitania and Gallia Narbonensis), that is, modern France south and west of the Loire, including Provence.
The diocese comprised the following provinces: Aquitanica I, Aquitanica II, Novempopulana (Aquitanica III), Narbonensis I, Narbonensis II, Viennensis and Alpes Maritimae
History
The diocese was established after the reforms of Diocletian and Constantine I in ca. 314 AD. In 407, the Vandals and their allies invaded Gaul, devastating the region until they departed for the Iberian peninsula in 409. The Visigoths were brought in as foederati to aid the Romans against them, and in 418 emperor Honorius allowed them to settle in Aquitania around Toulouse. Although nominally Roman subjects, the Goths were practically independent, a fact which was formally recognized by the Western Empire in 475, just one year before its end. In 462 Ricimer ceded them also the province of Narbonensis Prima, while the Goths proceeded to occupy the remaining provinces east of the Rhone in 477. Henceforth, the lands that had comprised the diocese of the Seven Provinces were part of the Visigothic Kingdom. Aquitania was soon lost to the Franks, with only the southern coastal strip (Septimania) retained by the Goths.
