Later tradition held that as far back as the 5th century BC, the Patrician and Plebeian classes disputed the rights of the rich to exploit the land, and in 367 BC two Plebeian Tribunes, Gaius Licinius Stolo and Lucius Sextius Sextinus Lateranus promulgated a law which limited the amount of the ager publicus to be held by any individual to 500 iugera, roughly 325 acres .
