The tribe was also a group of persons; in fact the word applies far more frequently to persons than to territory.[339] During the early republic a considerable degree of harmony was maintained between the two aspects of the institution (1) possibly by a restriction on the transfer of residence,[340] (2) by the change in membership from tribe to tribe, through the censors, on the basis of a transfer of domicile, (3) by the assignment of new citizens to the tribe in or near which they had their homes, (4) by the creation of new tribes for new citizens who did not live in or near the existing tribes. This harmony experienced its first serious disturbance through the enrolment of the landless, irrespective of domicile, in the urban tribes in 304,[341] but continued to such a degree that a hundred years later the rural voters generally still resided in their own tribes.[342] In the last century of the republic the personal tribe, emancipated from the local, depended solely on inheritance and the will of the censors.[343] The original composition of the personal tribe is determined by its purely military object. It comprised accordingly those only who were liable to service in war. From the early Roman point of view those citizens were qualified who found their livelihood in agriculture.[344] Not all landowners were enrolled in the tribes; for Latin residents,[345] freedmen,[346] widows and orphans,[347] all of whom might possess land, lacked membership. Those proprietors, too, were excluded whom the censors assigned to the aerarii as a punishment. Tribesmen were all the other landowners—adsidui[348] et locupletes[349]—together with the male descendants of military age under their potestas.[350]
