While this war was going on there was dreadful work at home. The slaves had, for the second time, broken into insurrection. This servile war was mainly in Sicily, where thousands of slaves were slain. Of the captives, many were taken to Rome to fight with wild beasts in the arena, but they disappointed the eager spectators by killing each other. This outbreak only made slavery at Rome harder and harsher than before.
Years passed on, and then another war broke out. The Italian allies, who had helped to make Rome great, claimed rights of citizenship and suffrage. These were denied, and what is known as the Social War began. Sulla and Marius took part in this conflict, which ended in favor of Rome, though the franchise fought for was in large measure gained. It was of little value, however, since all who held it were obliged to go to the city of Rome to vote.
During these various conflicts the rivalry between Marius and Sulla grew steadily more declared. The old plebeian, now seventy years of age, was jealous of the honors which his aristocratic rival had gained in the Social War, and a spirit of bitter hatred, which was to bear dire results, arose in his heart.
Events to come were to blow this spark of hatred into a glowing flame. A new war threatened Rome. Mithridates the Great, king of Pontus, in Asia Minor, was pursuing a career of conquest, and the Roman provinces in Asia were in danger. War was determined on, and Sulla, who had already held successful command in the East, claimed the command of the new army. Marius, old as he was, wanted it, too, and by his influence with the new citizens of Rome succeeded in defeating Sulla and gaining the appointment of general in the war against Pontus.
This vote of the tribes precipitated a contest. The Social War was not yet fully ended, and Sulla hastened to the camp where his soldiers were besieging a Samnite town. It was his purpose to set sail for the East before he could be superseded. He was too late. Officials from Rome reached the camp almost as soon as he, bearing a commission from Marius to assume the command. It was a critical moment. Sulla must either yield or inaugurate a civil war.
He chose the latter. Calling the soldiers together, he told them that he had been insulted and injured, and that, unless they supported him, they would be left at home, and a new army raised by Marius would obtain the spoils of the Mithridatic war. Stirred by this appeal to their avarice, the legions stoned to death the officers sent by Marius, and loudly demanded to be led to Rome.
Their coming took Marius by surprise, and threw the city into consternation. No one had dreamed of such daring and audacity. To lead a Roman army against Rome was unprecedented. The senate sent an embassy asking Sulla to halt till the Fathers could come to some decision. He promised to do so, but as soon as the envoys had gone he sent a force that seized the Colline Gate and entered the city streets. Here their progress was stopped by the people, who hurled tiles and stones upon their heads from the house-tops.
The whole army soon followed, and Sulla entered the city with two legions at his back. The people again opposed their march, but Sulla seized a torch and threatened to burn the city if any hostility were shown. This ended all opposition, except that made by Marius, who retreated to the Capitol, where he proclaimed liberty to all slaves who would join his banner. This did him much more harm than good; his adherents dispersed; he and his chief supporters were forced to seek safety in flight.
And now we have a story of striking interest to tell. It would need the powers of invention of a romancer to devise a series of adventures as remarkable as those which befell old Marius in his flight. It is one of the strangest stories in all the annals of history, a marked illustration of the saying that fact is often stranger than fiction.
