The Valerio-Horatian laws (Latin: leges Valeriae Horatiae) were three laws which were passed by the consuls of Rome for 449 BC, Lucius Valerius Poplicola Potitus and Marcus Horatius Barbatus. They restored the right of appeal to the people and introduced measures which were favourable to the plebeians. The consuls' actions came after a plebeian rebellion, the second plebeian secession, which overthrew the second decemvirate, which had ruled tyrannically. The two consuls had shown sympathy towards the plebeians and, as a result, had been chosen to negotiate the resolution of the rebellion. Their new laws quelled the plebeian unrest.
