Ripuarian or Rhineland Franks were one of the two main groupings of early Frankish people, and specifically it was the name eventually applied to the tribes who settled in the old Roman territory of the Ubii, with its capital at Cologne on the Rhine river in modern Germany. Their western neighbours were the Salii, or "Salian Franks", who were named already in late Roman records, and settled with imperial permission within the Roman Empire in what is today the southern part of the Netherlands, and Belgium, and later expanded their influence into the northern part of France north of the Loire river, creating the Frankish empire of Francia.

The Battle of the Catalaunian Plains, also called the Battle of the Campus Mauriacus, Battle of Châlons, Battle of Troyes or the Battle of Maurica, took place on June 20, 451 AD, between a coalition, led by the Roman general Flavius Aetius and the Visigothic king Theodoric I, against the Huns and their vassals, commanded by their king, Attila. It proved one of the last major military operations of the Western Roman Empire, although Germanic foederati composed the majority of the coalition army. Whether the battle was of strategic significance is disputed; historians generally agree that the siege of Aurelianum was the decisive moment in the campaign and stopped the Huns' attempt to advance any further into Roman territory or establish vassals in Roman Gaul. However, the Huns successfully looted and pillaged much of Gaul and crippled the military capacity of the Romans and Visigoths. Attila died only two years later, in 453; after the Battle of Nedao in 454 AD, the coalition of the Huns and the incorporated Germanic vassals gradually disintegrated.
