Size of Barbarian Migrations

[Urselius]

Also migratory peoples tended to change in numbers over time. The Cimbric migration picked up other tribes en-route. In the later migrations, groups such as the Goths recruited disaffected Roman soldiers, citizens, and slaves to their ranks once within the Empire's borders. Sections of hordes could also be suborned by the Roman authorities and given settlement within Roman territory, therby weakening the parent group.
