But the most important triumph was that the assemblies of the plebs succeeded by degrees in securing official recognition for the resolutions they passed on legal, judicial, and political questions. After the year 287 B.C. the plebiscita had the same force as laws (leges) passed by the whole body of the people.
Although the subject classes had thus won a satisfactory measure of civil rights and liberties, they never forgot—and this is the most significant feature of the whole struggle for liberty—that none but a strong government and magistracy can successfully meet ordinary demands or rise to extraordinary emergencies. At Rome the individual magistrate found his liberty of action restrained in many ways by his colleagues and superiors. But within the scope of his jurisdiction, his provincia, he enjoyed a considerable amount of independence.
The senate was the only power which ultimately contrived to impose limits upon this independence. In that body the effective authority of the government was concentrated by gradual degrees. In face of the constant augmentation in the number of magistrates it frequently succeeded in getting its own way without much trouble. In the bosom of its members reposed the arcana imperii, the secrets of a policy which had known how to make Rome great. Selfishness, consistency, perfidy, perseverance—such were the motives, some noble, and some base, which shaped its resolutions. Yet we cannot deny that there is a certain grandeur in the political aims represented by the senate. Nor did it fail of success; indeed, its achievements were marvellous.
In the year 390 B.C. the city of Rome was in the hands of the Gauls, and the Roman body politic had to all appearance perished. Exactly a hundred years later, at the end of the Second Samnite War, Rome was mistress of nearly the whole of Italy. A few years more, and she occupied Tarentum (272) and Rhegium (270). What is the explanation of this prodigious change?
It would be unjust not to assign its due share in the matter to the admirable temper of the Roman people. The self-sacrificing patriotism they invariably displayed, their stubborn endurance in perilous times, their manly readiness to hazard everything, even their very lives, if the welfare of the city so required—these qualities marked the Romans of that age, and they are capable of accomplishing great things. By them the admirable military system of Rome was first fitted for the great part it had to play in the history of the world, and became a weapon which never turned back before the most formidable of foes, and gave the assurance of lasting success.
In process of time the ancient Servian phalanx had been superseded by an admirably organised and mobile disposition of the troops in maniples of 160 men each. Ranged in three files, with lateral spaces between, these bodies relieved one another during the fight, and thus were able to quell the most vehement onslaught of the enemy by constantly bringing forward fresh troops, which first hurled their long javelins and then charged with their short swords.
It became more and more the practice of the Roman state to extend to the lower classes the obligation of military service, which in all other parts of Italy was a privilege of the assidui or freeholders. Large numbers of landless men and freedmen were enrolled in the recruiting districts (tribus) in war times by the famous censor Appius Claudius Cæcus.
Opportune political changes favoured the development of Roman supremacy in Italy. The Etruscan dominion had fallen into utter decay during the course of the fifth century. Rome’s victorious struggle for liberty, the advance of the Samnites in southern Italy, and the immigration of the Gauls into northern Italy, had reduced Etruria to a second-class power. In the south the power of the wealthy Greek cities had been broken by Dionysius of Syracuse. Step by step Roman colonists made their way into lower Italy. Where the sword was of no avail Rome had recourse to road-making, the occupation and cultivation of waste land, and fresh settlements. Above all, the Latin colonies which she established in concert with the Latin league were of the utmost importance in securing the supremacy of Rome in middle Italy. These colonies served as fortresses, the colonists were a garrison always ready to stand on the defensive. The colonies themselves were established in such a way as to obstruct the coalition of the various races of Italy. They spread abroad Latin law and the Latin language among foreigners. They once more united the Romans and Latins in a common work of civilisation, after the two peoples had so hotly fought against each other in what is known as the Great Latin War (340-338 B.C.).
The skilful diplomatic negotiations and settlements by which Rome contrived either to gain over her former adversaries or reduce them to neutrality before she engaged in the struggle with the Samnites for the hegemony of Italy (342-340 and 326-304) are particularly worthy of note. She protected her rear by concluding armistices for many years with the Etruscans (351-311) and Gauls (329-299). She entered into friendly relations with the Greek cities, and won over many communities in Campania and Lucania which had put themselves under the protection of the Samnites. Nay, she did not shrink from purchasing the friendship of Carthage by allowing her to take and plunder the seaboard cities of middle Italy which had revolted against Roman dominion. And she further displayed remarkable skill in securing her tenure of the possessions won in the Samnite wars. Only a small part of them was incorporated with Roman territory. Many cities received an accession of Latin colonists and so retained their municipal autonomy under new conditions. On the other hand the connection between the recalcitrant cantons of the Sabellian, Etruscan, and Middle Italian tribes was completely broken. Isolated and deprived of the right of intercourse (commercium) the various small cities and communities ceased to be of any importance either economically or politically.
The Romans had hardly completed the conquest of Etruria and the Samnite confederacy in the Third Samnite War (298-290 B.C.), and subjugated the kindred districts of Lucania and Bruttium when they found themselves involved in the struggles which then agitated the Greek world.
After 301 the several parts of the empire of Alexander the Great had become independent kingdoms. But the quarrels among the various diadochi went on and ultimately led to the expulsion of Demetrius Poliorcetes from Macedonia and the fall of Lysimachus of Thrace.
The unsettled state of these kingdoms inspired hordes of Gauls, athirst for plunder, with the idea of crossing the Alps and conquering both the Apennine and Balkan peninsulas. Italy owed her salvation to the vigorous defence made by the Romans at the Vadimonian Lake (283 B.C.); but Macedonia was occupied for several years and the swarms of Gauls spread as far as Delphi, and finally settled in Asia Minor under the name of Galatians.
Even before the Gallic invasion, Pyrrhus of Epirus, who had taken possession of Macedonia for a while, had withdrawn to his own home, and he and his army of mercenaries turned their eyes westward, eager for action. The wished-for opportunity of there regaining the influence and reputation he had lost in the west was not slow to present itself. Tarentum, the last independent city of any importance in Italy, had provoked Rome to hostilities and was endeavouring to enlist mercenaries for the war. Pyrrhus went to the help of the Tarentines, even as Alexander of Epirus, a cousin of Alexander the Great, had gone before him (334 B.C.). After some initial successes the latter had lost his life in battle against the Lucanians (331 B.C.). His nephew did not fare much better. The generalship of Roman mayors, elected afresh every year, was at first no match for that of Pyrrhus, who had great military successes to look back upon. Up to this time the Macedonian phalanx had invariably proved the instrument of victory, especially in the opening encounters of a campaign, and even the men of Rome gave ground before the elephants, the “heavy artillery” of the Epirots. But the second victory which the king gained over the Romans was a “Pyrrhic victory,” for his gains did not compensate his losses. On this occasion Rome owed the victory mainly to the inflexible courage of her statesmen. The blind Appius Claudius, who thirty years before had borne an honourable part in the successful struggle with the Samnites, caused himself to be led into the senate and by his arguments induced the Romans inflexibly to refuse all offers of peace on less than favourable terms. “Never have the Romans concluded peace with a victorious foe.” These proud words contain the secret of the ultimate success of Rome in all her wars of that century.
