Lat. In Roman law. A legal marriage, contracted in strict accordance with the forms of the older Roman law, #4. e., either with the farreum, the coemptio, or by usus. This was allowed only to Roman citizens and to those neighboring peoples to whom the right of connubium had been conceded. The effect of such a marriage was to bring the wife into the manus, or marital power, of the husband, and to create the patria potestas over the children.
