In the doubtful transition period, as the tradition goes, it is in the time of discontented plebeian subjection, after the expulsion of the king (510 B.C.), that the Etruscan enemy captures the city (497); and the surmise that the battle of Lake Regillus was not really a Roman victory[40] is partly strengthened by the fact that soon after it there occur the division into twenty-five tribes, the tumults of the nexi, and the successful Secession of the Plebs, ending in their incorporation, with two tribunes to represent their interests (494). There is a clear presumption that only from a weakened patriciate, forced to seek union, could the plebs have won their tribunate and enfranchisement. On the other hand, it is after victories over the Volscians that the consul Spurius Cassius, who had proposed to divide among landless men the land conquered from the Hernicans, is said to have been executed (485) by the triumphant aristocracy; and it is in another period of security, when the Veientines and Sabines are depressed (473), that the tribune Cneius Genucius is murdered for having ventured to bring a consular to trial. Always we are in presence of a brutal caste, in the main utterly selfish, some of whose members are at all times as prone to the use of the dagger as an Italian _camorra_ of our own day. Yet it is by the forcing of concessions on this caste that the Roman polity is kept vigorous and adaptable in comparison with those of the surrounding States which Rome subordinated or overran.
