Historians debunk theory that barbarian recruitment caused Rome's fall. The 'Lieuitz thesis' proposes barbarian dominance in the late Roman military led to Rome's collapse Historian JHWG Lieuitz (d. 2022) was a prominent scholar of the late Roman Empire Hugh Elton estimates 20-25% of military personnel had non-Roman origin in late antiquity
The 'Liebeschuetz thesis' argues barbarian dominance in the late Roman military caused Rome's collapse — but modern historians don't buy it.
