The Plebeians were, however, not wholly without constitutional rights. From an early period they had been admitted to some share of political power. They were enrolled each in his century, and were allowed a share, considerable though not proportioned to their numerical strength, in the disposal of those high dignities from which they were themselves excluded. Thus their position bore some resemblance to that of the Irish Catholics during the interval between the year 1792 and the year 1829. The Plebeians had also the privilege of annually appointing officers, named Tribunes, who had no active share in the government of the commonwealth, but who, by degree, acquired a power formidable even to the ablest and most resolute Consuls and Dictators. The person of the Tribune was inviolable; and, though he could directly effect little, he could obstruct everything.

During more than a century after the institution of the Tribuneship, the Commons struggled manfully for the removal of the grievances under which they labored; and, in spite of many checks and reverses, succeeded in wringing concession after concession from the stubborn aristocracy. At length in the year of the city 378, both parties mustered their whole strength for their last and most desperate conflict. The popular and active Tribune, Caius Licinius, proposed the three memorable laws which are called by his name, and which were intended to redress the three great evils of which the Plebeians complained. He was supported, with eminent ability and firmness, by his colleague, Lucius Sextius. The struggle appears to have been the fiercest that every in any community terminated without an appeal to arms. If such a contest had raged in any Greek city, the streets would have run with blood. But, even in the paroxysms of faction, the Roman retained his gravity, his respect for law, and his tenderness for the lives of his fellow citizens. Year after year Licinius and Sextius were reëlected Tribunes. Year after year, if the narrative which has come down to us is to be trusted, they continued to exert, to the full extent, their power of stopping the whole machine of government. No curule magistrates could be chosen; no military muster could be held. We know too little of the state of Rome in those days to be able to conjecture how, during that long anarchy, the peace was kept, and ordinary justice administered between man and man. The animosity of both parties rose to the greatest height. The excitement, we may well suppose, would have been peculiarly intense at the annual election of Tribunes. On such occasions there can be little doubt that the great families did all that could be done, by threats and caresses, to break the union of the Plebeians. That union, however, proved indissoluble. At length the good cause triumphed. The Licinian laws were carried. Lucius Sextius was the first Plebeian Consul, Caius Licinius the third.
