List of Roman laws

This is an attempted alphabetical List of Roman laws. The name of the law is usually the gens of the legislator, declined on the female form (because in latin language law - lex, plural leges - is a word with female gender). When a law is the initiative of the two consuls, is given the name of the two, with the senior consul gens signalled first. Sometimes, a short description of the content of the law is added.

Note - The list is very incomplete: you can help Wikipedia by adding laws to it.

  • Twelve Tables – The first set of Roman laws published by the '\'Decemviri'' in 451 BC, which would be the starting point of the elaborate Roman constitution.

  • Note 1 – The word Republic derives from the Latin res publica (literally, public thing). The Romans often wrote the two words as one, respublica and inflected both words.
