In less than a hundred years new strifes arose between the more cultured Samnites of the plain and their rough and warlike kinsmen in the mountains. But Rome took a part in the struggle, and in the Samnite Wars (343-290 B.C.) brought both the men of the mountains and the men of the plain under her dominion. Although the sovereignty of Rome took the form of a perpetual alliance, the cities in reality lost their independence. The complete subjugation and Romanizing of Campania, however, did not come till the time of the Social War (90-88 B.C.) and the supremacy of Sulla; the Samnites staked all on the success of the popular party, and lost. In the narrative of these events Pompeii is not often mentioned. At the time of the Second Samnite War, in the year 310 B.C., we read that a Roman fleet under Publius Cornelius landed at the mouth of the Sarno, and that a pillaging expedition followed the course of the river as far as Nuceria; but the country folk fell on the marauders as they were returning, and forced them to give up their booty. We have no definite information regarding the attitude of the Pompeians after the battle of Cannae (216 B.C.); probably they joined the side of Hannibal, who, however, was defeated by Marcus Marcellus near Nola in the following year, and was obliged to leave Campania to the Romans. In the Social War, when, in the summer of 90 B.C., the Samnite army marched into Campania, Pompeii allied itself with the insurgents; as a consequence, in 89, it was besieged by Sulla, but without success. Two years later, Sulla went to Asia to conduct the war against Mithridates. Returning victorious in the spring of 83 B.C., he led his army into Campania, where he spent the winter of 83-82; his soldiers, grown brutal in the Asiatic war and accustomed to every kind of license, may have proved unwelcome guests for the Pompeians. The sequel came in the year 80, when a colony of Roman veterans was settled in Pompeii under the leadership of Publius Sulla, a nephew of the Dictator. Cicero later made a speech in behalf of this Sulla, defending him against the charge that he had taken part in the conspiracy of Catiline and had tried to induce the old residents of Pompeii to join in the plot. From this speech we learn that Sulla's reorganization of the city was accomplished with so great regard for the interests of the Pompeians, that they ever after held him in grateful remembrance. We learn, also, that soon after the founding of the colony disputes arose between the old residents and the colonists, about the public walks (_ambulationes_) and matters connected with the voting; the arrangements for voting had probably been so made as to throw the decision always into the hands of the colonists. The controversy was referred to the patrons of the colony, and settled by them. From this time on, the life of Pompeii seems not to have differed from that of the other small cities of Italy.
