The other peoples underwent quickly the laws of the conqueror. The inhabitants of Picenum, as a punishment for their revolt, were despoiled of a part of their territory, and a certain number among them received new lands in the south of Campania, near the Gulf of Salernum (_Picentini_)(486). In 487, the submission of the Salentines allowed the Romans to seize Brundusium, the most important port of the Adriatic.[216] The Sarsinates were reduced the years following.[217] Finally, Volsinium, a town of Etruria, was again numbered among the allies of the Republic. The Sabines received the right of suffrage. Italy, become henceforth Roman, extended from the Rubicon to the Straits of Messina. [Sidenote: Preponderance of Rome.] X. During this period, the conquest of the subjugated countries was ensured by the foundation of colonies. Rome became thus encircled by a girdle of fortresses commanding all the passages which led to Latium, and closing the roads to Campania, Samnium, Etruria, and Gaul.[218] At the opening of the struggle which ended in the conquest of Italy, there were only twenty-seven tribes of Roman citizens; the creation of eight new tribes (the two last in 513) raised finally the number to thirty-five, of which twenty-one were reserved to the old Roman people and fourteen to the new citizens. Of these the Etruscans had four; the Latins, the Volsci, the Ausones, the Æqui, and the Sabines, each two; but, these tribes being at a considerable distance from the capital, the new citizens could hardly take part in the comitia, and the majority, with its influence, remained with those who dwelt at Rome.[219] After 513, no more tribes were created; those who received the rights of citizens were only placed in the previously existing tribes; so that the members of one individual tribe were scattered in the provinces, and the number of those inscribed went on increasing continually by individual additions, and by the tendency more and more apparent to raise the municipia of the second order to the rank of the first order. Thus, towards the middle of the sixth century, the towns of the Æqui, the Hernici, the Volsci, and a part of those of Campania, including the ancient Samnite cities of Venafrum and Allifæ, obtained the right of city with suffrage.
