451 AD

The year 451 AD was notable for the Battle of the Catalaunian Plains, where Roman, Visigoth, and other allied forces stopped the advancing Huns led by Attila from overrunning Gaul (modern-day France). It was a significant event in late Roman history, illustrating the ongoing struggle for power and territory among Roman authorities and migrating barbarian groups. Though not a decisive victory, it marked a key moment in halting Attila’s invasion, shaping the region's political landscape for years to come.
