It is in this climate that, despite his earlier setback, Alaric returned again in 410 AD and managed to sack Rome. The Roman capital had by this time moved to the Italian city of Ravenna, but some historians view 410 AD as an alternative date for the true fall of the Roman Empire. Without possession of Rome or many of its former provinces, and increasingly Germanic in nature, the Roman Empire after 410 AD had little in common with the earlier Empire. By 410 AD, Britain had been mostly denuded of Roman troops, and by 425 AD was no longer part of the Empire, and much of western Europe was beset "by all kinds of calamities and disasters", coming under barbarian kingdoms ruled by Vandals, Suebians, Visigoths and Burgundians.
