Commercium was the right of any Latinus (see latini) to own Roman land and to enter into contracts with a Roman that were according to the forms of Roman law and enforceable in Roman courts without recourse to the *ius gentium (especially using conveyance by *mancipatio).This belonged to a Latinus by right (Romans possessed a reciprocal commercium in Latin communities) but might also be given as a privilege to foreigners. Without it a foreigner could only go to law through the actions granted by the peregrine praetor (see praetor). Associated with commercium was conubium, the right to contract a legal marriage with a member of another state without either party forfeiting inheritance or paternity rights. Without conubium a Roman's children by a foreigner took the citizenship of the foreigner and could not be heirs to his property. These complementary rights formed an essential part of *ius Latii.
