List of Roman laws

This is a partial list of Roman laws. A law (Latin lex) is usually named for the sponsoring legislator and designated by the adjectival form of his family or gens name (nomen gentilicum). Because the noun lex (plural leges) is of feminine grammatical gender, its adjective is also feminine in form. When a law is the initiative of the two consuls, it is given the name of both, with the nomen of the senior consul first. Sometimes a law is further specified by a short phrase describing the content of the law, to distinguish that law from others sponsored by members of the same family.

Some laws listed have been made after the fall of the Western Roman Empire, but they were heavily influenced by Roman laws that were made before.
