lex Iulia de Maritandis Ordinibus

The law of Augustus concerning the regulation of marriage (18 bce), a plebiscite often treated in conjunction with the consular law of Papius and Poppaeus (lex Papia Poppaea, 9 ce, together as lex Iulia et Papia), primarily obliges all Roman citizens to enter into marriage with the purpose of producing legitimate offspring. With this goal, the law probably contained set age limits at which point one was expected to have been married, an age likely reflective of the fertility age, and an extensive list of rewards and privileges for those producing (legitimate) offspring.
