The Achaean exiles, whose numbers were now reduced from 1000 to 300, landed in Greece (B.C. 151) with feelings exasperated by their long confinement, and ready to indulge in any rash enterprise against Rome. Polybius, who had returned with the other exiles, in vain exhorted them to peace and unanimity, and to avoid a hopeless struggle with the Roman power. Shortly afterward an adventurer laid claim to the throne of Macedonia (B.C. 149). He was a man of low origin called Andriscus, but he pretended to be the son of Perseus, and assumed the name of Philippus. At first he met with some success, and defeated the Roman Praetor Juventius, but, after reigning scarcely a year, he was conquered and taken prisoner by Q. Metellus. The temporary success of Andriscus had encouraged the war-party in the Achaean League. Polybius had quitted the country to join his friend Scipio in Africa; and Diaeus and Critolaues, the most violent enemies of Rome, had now undisputed sway in the League. Diaeus incited the Achaeans to attack Sparta, on the ground that, instead of appealing to the League respecting a boundary question, as they ought to have done, they had violated its laws by sending a private embassy to Rome. The Spartans, feeling themselves incompetent to resist this attack, appealed to the Romans for assistance; and in B.C. 147 two Roman commissioners were sent to Greece to settle these disputes. The commissioners decided that not only Sparta, but Corinth, and all the other cities, except those of Achaia, should be restored to independence. Their decision occasioned serious riots at Corinth. All the Spartans in the town were seized, and even the Roman commissioners narrowly escaped violence. On their return to Rome a fresh embassy was dispatched to demand satisfaction for these outrages. But the violent and impolitic conduct of Critolaues, then Strategus of the League, rendered all attempts at accommodation fruitless, and, after the return of the embassadors, the Senate declared war against the League. The cowardice and incompetence of Critolaues as a general were only equaled by his previous insolence. On the approach of the Romans from Macedonia under Metellus he did not even venture to make a stand at Thermopylae; and, being overtaken by them near Scarphea, in Locris, he was totally defeated, and never again heard of. Diaeus, who succeeded him as Strategus, displayed rather more energy and courage, and made preparations to defend Corinth. Metellus had hoped to have had the honor of bringing the war to a conclusion, and had almost reached Corinth, when the Consul L. Mummius landed on the Isthmus and assumed the command. The struggle was soon brought to a close. Diaeus was defeated in battle; and Corinth was immediately evacuated, not only by the troops of the League, but also by the greater part of the inhabitants. On entering the city, Mummius put to the sword the few males who remained, sold the women and children as slaves, and, having
