Between 135 BC and 71 BC there were three Servile Wars against the Roman state; the third, and most serious, may have involved the revolution of 120,000 to 150,000 slaves. Additionally, in 91 BC the Social War broke out between Rome and its former allies in Italy, collectively known as the "Socii", over the grievance that they shared the risk of Rome's military campaigns, but not its rewards. Despite defeats such as the Battle of Fucine Lake, Roman troops defeated the Italian militias in decisive engagements, notably the Battle of Asculum. Although they lost militarily, the "Socii" achieved their objectives with the legal proclamations of the "Lex Julia" and "Lex Plautia Papiria", which granted citizenship to more than 500,000 Italians.
