AN important though infrequently discussed aspect of Britain's legionary fortresses is the existence, on the analogy of the arrangements made in other provinces, around each of them of a large tract of land which came under the direct control of the resident legion. As a citizen body headed by a deputy or legatus of the emperor a legion could ‘possess’ a territory on behalf of the Roman People and, for administrative and legal purposes, be regarded as a locally sovereign respublica in just the same way as a chartered town or a formally constituted native civitas, as is evidenced by instances where the boundaries of civil territoria run with those of army lands, implying equivalent status. Although lands were also allotted to auxiliary units, overall control of such areas is likely to have rested with the legate of the closest legion, a situation which not only stemmed from the fact that the auxilia were both in theory and in reality auxiliaries to the legions but which also reflected their origin in a period when the legions could be contrasted as wholly citizen bodies with the overwhelmingly peregrine auxilia.
