Thus it was, by unparalleled heroism in war, and a uniform policy in government, that Rome became the mistress of the world. The Roman conquests have never been surpassed, for they were retained until the empire fell. I wish that I could have dwelt on these conquests more in detail, and presented more fully the brilliant achievements of individuals. It took nearly two hundred years, after the expulsion of the kings, to regain supremacy over the neighboring people, and another century to conquer Italy. The Romans did not contend with regular armies until they were brought in conflict with the king of Epirus and the phalanx of the Greeks, "which improved their military tactics, and introduced between the combatants those mutual regards of civilized nations which teach men to honor their adversaries, to spare the vanquished, and to lay aside wrath when the struggle is ended." In the fifth century of her existence, the republic appears in peculiar splendor. Military chieftains do not transcend their trusts; the aristocracy are equally distinguished for exploits and virtues; the magistrates maintain simplicity of manners and protect the rights of the citizens; the citizens are self-sacrificing and ever ready to obey the call to arms, laying aside great commands and retiring poor to private stations. Marcus Valerius Corvus, after filling twenty-one curule offices, returns to agricultural life; Marcus Curius Dentatus retains no part of the rich spoils or the Sabines; Fabricius rejects the gold of the Samnites and the presents of Pyrrhus. The most trustworthy are elevated to places of dignity and power. Senators mingle in the ranks of the legions, and eighty of them die on the field of Cannae. Discipline is enforced to cruelty, and Manlius Torquatus punishes with death a disobedient son. Soldiers who desert the field are decimated or branded with dishonor. Faith is kept even with enemies, and Regulus returns a voluntary prisoner to his deadly enemies. [Sidenote: Results of different wars.] After the consolidation of Roman power in Italy, it took one hundred and fifty years more only to complete the conquest of the world--of Northern Africa, Spain, Gaul, Illyria, Epirus, Greece, Macedonia, Asia Minor, Pontus, Syria, Egypt, Bithynia, Cappadocia, Pergamus, and the islands of the Mediterranean. The conquest of Carthage left Rome without a rival in the Mediterranean, and promoted intercourse with the Greeks. The Illyrian wars opened to the Romans the road to Greece and Asia, and destroyed the pirates of the Adriatic. The invasion of Cisalpine Gaul, now that part of Italy which is north of the Apennines, protected Italy from the invasion of barbarians. The Macedonian War against Philip put Greece under the protection of Rome, and that against Antiochus laid Syria at her mercy; and when these kingdoms were reduced to provinces, the way was opened to further conquests in the East, and the Mediterranean became a Roman lake.
