Previous to the reign of Antoninus Pius, the privileges granted to the recipient of a diploma include citizenship for himself, the full legalization of any matrimonial union into which he has entered or shall enter in the future (_conubium_), and civic rights for his wife, children, and descendants. If he already possessed a family, the names of his wife and children follow his own on the diploma, and the frequency of this occurrence shows the extent to which the military authorities permitted the soldiers to form family ties while on active service.[65] The significance of this fact and its effect on the character of the army will be discussed in a later section. At the beginning of the reign of Antoninus Pius, a change takes place in that part of the formula which concerns the grant of citizenship. In place of the words _ipsis liberis posterisque eorum civitatem dedit et conubium cum uxoribus_, &c., we read in all the later examples, _civitatem Romanam, qui eorum non haberent, dedit et conubium cum uxoribus_, &c.[66] The first inference to be drawn from this alteration is that there now existed a numerous group of auxiliary soldiers who possessed the _civitas_ before their discharge, and we are probably justified in the further inference that many actually possessed it when they were enrolled. It has been noted, for example, that on a document dating from the reign of Trajan, six recruits accepted for the Cohors III Ituraeorum all have the _tria nomina_.[67] In this change, then, we have a clear instance of the extent to which the franchise was now diffused throughout the Empire.
