He reigned over what was then Europe's largest empire, from 434 until his death. His empire stretched from Germany and the Netherlands to the Ural river and from the Danube River to Poland and Estonia. During his rule, he was among the most dire of the Western and Eastern Roman Empire's enemies: he invaded the Balkans twice and besieged Constantinople in the second invasion; he marched through Gaul (modern day France) as far as Orleans before being defeated at the Battle of Chalons; and he drove the western emperor Valentinian III from his capital at Ravenna in 452.
