 The barbarisation of the lower ranks was paralleled by a concurrent barbarisation of its command structure, with the Roman senators who had traditionally provided its commanders becoming entirely excluded from the army.By 235 AD the Emperor himself, the figurehead of the entire military, was a man born outside of Italy to non-Italian parents.The gradual inclusion of greater numbers of non-citizen troops into the military was taken a further step by the creation under Hadrian of a new type of force in addition to the legions and "auxilia", known as "numeri".
