Under Diocletian (3rd century AD), Germania Superior was renamed "Germania Secunda", while Germania Inferior was renamed "Maxima Sequanorum". Both provinces were under the Diocese of Gaul. The provinces of Roman Germania continued to be subjected to repeated Alemannic and Frankish attacks. In the late 4th century AD and early 5th century AD, Gothic Wars in the Balkans forced the Romans to withdraw troops from Roman Germania. In 406, a large number of people fleeing the Huns crossed the Rhine from Magna Germania into Roman Germania and Gaul, leading to the eventually collapse of Roman rule there, and the emigration of large numbers of Romans, particularly Roman elites. Roman Germania was subsequently occupied by Alemanni and Franks. During subsequent centuries, peoples of Germania played a major role in dismembering what was left of the Western Roman Empire. Large parts of Germania, including all of Roman Germania, were eventually incorporated into the Frankish Empire.
