From 408 to 420 two men dominated the political landscape of southern Gaul: Constantine III and Constantius. They found there a region that was rife with centrifugal forces - fierce city rivalries, a squabbling priesthood, and an opportunistic nobility. But they also found a region whose unique resources made it indispensable to the stability of their regimes; southern Gaul was then both highly urbanised and rich in commerce, a prime source for taxes and educated bureaucratic officers. Not surprisingly, both Constantine and Constantius focused a great deal of energy on ensuring the continued loyalty and stability of the region. Both men were soldiers, and thus occasionally brutal in pursuit of their objectives, but their Gallic policies also reflected intelligent statecraft and an acute awareness of the changing world in which they lived. It was a world in which the border between Christianity and politics was rapidly fading, and the work of these two men both anticipated and epitomized the mixture of religion and realpolitik so characteristic of the medieval world.
