Quick Summary

The Jus Flavianum was a work published around 304 BC by Gnaeus Flavius, a Roman legal writer and politician. Flavius made public the previously secret rules of legal procedure that were guarded by patricians and pontifices. This allowed the Roman people to learn the necessary verbal formulas for legal proceedings (legis actiones) and the specific days when legal actions could be initiated (dies fasti).1

Flavius's actions, while weakening the power of the nobles and stemming from his plebeian birth, led to his popularity and election to public offices, including senator and curule aedile.1
