Fall of the Western Roman Empire
During the reign of Diocletian, the province was integrated into the "praeses" of the Diocese of Gaul. In 381, the first Bishop of the region, Theodul, was mentioned. After the Fall of the Western Roman Empire, the region was invaded by the Burgundians and incorporated into their kingdom. After its fall, it was integrated into the Frankish Kingdom in 534, then briefly invaded by the Lombards in 574.
