Marriage in ancient Rome conubium was a fundamental institution of society and was used by Romans primarily as a tool for interfamilial alliances. The institution of Roman marriage was a practice of marital monogamy : Roman citizens could have only one spouse at a time in marriage but were allowed to divorce and remarry.
This form of prescriptively monogamous marriage that co-existed with male resource polygyny [ a ] in Greco-Roman civilization may have arisen from the relative egalitarianism of democratic and republican city-states. Early Christianity embraced this ideal of monogamous marriage by adding its own teaching of sexual monogamy , and perpetrated it worldwide and became as an essential element in many later Western cultures.
Roman marriage had precedents in myth. The abduction of the Sabine Women may reflect the archaic custom of bride abduction. Rome's Sabine neighbours rejected overtures of intermarriage conubium by Romulus and his band of male immigrants. According to Livy , Romulus and his men abducted the Sabine maidens but promised them honorable marriage, in which they would enjoy the benefits of property, citizenship, and children.
Marriages helped families to build economic and political bonds and alliances. Matrimonium , the root of the English word matrimony , defined the role of wives as mothers matres who would produce legitimate children , as eventual heirs to their parents' estates.
The most ancient form of marriage, traditionally reserved to the Patrician social class, claimed the husband's right to control his wife and her property. In later developments, the bride retained control over her dowry; the resources of both parties formed a heritable estate.
