what was the result in the inclusion of barbarians in the army
Fall of the Western Roman Empire Within the late Roman military, many recruits and even officers had barbarian origins, and soldiers are recorded as using possibly-barbarian rituals such as elevating a claimant on shields.[32] Some scholars have seen this as an indication of weakness; others disagree, seeing neither barbarian recruits nor new rituals as causing any problem with the effectiveness or loyalty of the army.[33]
Third Servile War The revolt began in 73 BC, with the escape of around 70 slave-gladiators from a gladiator school in Capua; they easily defeated the small Roman force sent to recapture them. Within two years, they had been joined by some 120,000 men, women and children; the able-bodied adults of this band were a surprisingly effective armed force that repeatedly showed they could withstand or defeat the Roman military, from the local Campanian patrols, to the Roman militia, and to trained Roman legions under consular command. The slaves wandered throughout Italia, raiding estates and towns with relative impunity, sometimes dividing their forces into separate but allied bands under the guidance of several leaders, including the famous gladiator-general Spartacus.
