*The Italian Confederacy.* The death of Drusus was the signal for a revolt of the Italian allies. They had been in close alliance with him, and had taken steps for concerted action in arms if his bill should fail to pass. A confederacy was organized, the government of which was vested in a Senate of five hundred members with absolute powers, having as executive officers two annual consuls and twelve praetors. The capital of the confederacy was at Corfinium, in the territory of the Paeligni, which was renamed Italia. A federal coinage was issued. Before opening hostilities the Italians made a formal demand for Roman citizenship, which the Senate definitely refused. Thereupon they declared their independence. *The resources of the rivals.* The Italian Confederacy embraced practically all the warlike peoples of central and southern Italy. Of particular importance were the Marsi who gave their name to the war. In numbers the Italians were a match for the Romans, and they had acquired Roman military tactics, organization and discipline through long service in the Roman armies. They also could count on leaders of approved ability. But the Latin colonies and the Greek cities in the south remained true to their allegiance, and thus the Italians were cut off from the coast. Furthermore Umbria and Etruria, although disaffected, did not at once take up arms. Rome’s control of the sea enabled her to draw upon the resources of the provinces in men, money, and supplies, and consequently she was in a much better position to sustain a prolonged struggle. *The first year of the war: 90 B. C.* Hostilities opened in 90 B. C. with the Italian forces attempting to reach Etruria in the north and occupy Campania in the south and the Romans trying to forestall them by invading the territory of the allies. In the south the year’s campaign resulted in numerous Roman disasters. Much of Campania was won by the allies who succeeded in penetrating to the coast. In the north the Romans also suffered defeats, but were able to maintain themselves and win several successes. Here Marius, in the capacity of a _legatus_, rendered valuable service. Before the close of the year the revolt began to spread to Etruria and Umbria. Thereupon the Romans, with the object of securing the support of their still faithful allies and of weakening the ranks of the rebels, passed the Julian Law which granted Roman citizenship to all who had not joined the revolt and all who should at once lay down their arms. In this way the Umbrians and Etrurians were quieted, the Latins and the Greek allies rewarded, and many communities, which sought Roman citizenship but not independence, induced to surrender.
