Under such circumstances the number of the inhabitants of that State could never much increase. For as all our actions imitate nature, and it is neither natural nor possible that a puny stem should carry a great branch, so a small republic cannot assume control over cities or countries stronger than herself; or, doing so, will resemble the tree whose boughs being greater than its trunk, are supported with difficulty, and snapped by every gust of wind. As it proved with Sparta. For after she had spread her dominion over all the cities of Greece, no sooner did Thebes rebel than all the others rebelled likewise, and the trunk was left stripped of its boughs. But this could not have happened with Rome, whose stem was mighty enough to bear any branch with ease.
It was, therefore, by adding to her population, and by, adopting certain other methods presently to be noticed, that Rome became so great and powerful. And this is well expressed by Titus Livius, in the words, “Crescit interea Roma Albae ruinis.”
CHAPTER IV.—That Commonwealths have followed three Methods for extending their Power.
Any one who has read ancient history with attention, must have observed that three methods have been used by republics for extending their power. One of these, followed by the old Etruscans, is to form a confederation of many States, wherein none has precedence over the rest in authority or rank, and each allows the others to share its acquisitions; as do the States of the Swiss League in our days, and as the Achaians and Etolians did in Greece in earlier times. And because the Etruscans were opposed to the Romans in many wars, that I may give a clearer notion of this method of theirs, I shall enlarge a little in my account of the Etruscan people.
In Italy, before the Romans became supreme, the Etruscans were very powerful, both by sea and land; and although we have no separate history of their affairs, we have some slight records left us of them, and some indications of their greatness. We know, for instance, that they planted a colony, to which they gave the name of Hadria, on the coast of the upper sea; which colony became so renowned that it lent its name to the sea itself, which to this day by the Latins is called the Hadriatic. We know, too, that their arms were obeyed from the Tiber to the foot of the mountains which enclose the greater part of the Italian peninsula; although, two hundred years before Rome grew to any great strength, they had lost their supremacy in the province now known as Lombardy, of which the French had possessed themselves. For that people, whether driven by necessity, or attracted by the excellence of the fruits, and still more of the wine of Italy, came there under their chief, Bellovesus; and after defeating and expelling the inhabitants of the country, settled themselves therein, and there built many cities; calling the district Gallia, after the name they then bore: and this territory they retained until they were subdued by the Romans.
These Etruscans, therefore, living with one another on a footing of complete equality, when they sought to extend their power, followed that first method of which I have just now spoken. Their State was made up of twelve cities, among which were Chiusi, Veii, Friuli, Arezzo, Volterra, and the like, and their government was conducted in the form of a league. They could not, however, extend their conquests beyond Italy; while even within the limits of Italy, much territory remained unoccupied by them for reasons presently to be noticed.
The second method is to provide yourself with allies or companions, taking heed, however, to retain in your own hands the chief command, the seat of government, and the titular supremacy. This was the method followed by the Romans.
The third method is to hold other States in direct subjection to you, and not merely associated with you as companions; and this was the plan pursued by the Spartans and Athenians.
Of these three methods, the last is wholly useless, as was seen in the case of the two States named, which came to ruin from no other cause than that they had acquired a dominion greater than they could maintain. For to undertake to govern cities by force, especially such cities as have been used to live in freedom, is a difficult and arduous task, in which you never can succeed without an army and that a great one. But to have such an army you must needs have associates who will help to swell the numbers of your own citizens. And because Athens and Sparta neglected this precaution, whatever they did was done in vain; whereas Rome, which offers an instance of the second of the methods we are considering, by attending to this precaution reached a power that had no limit. And as she alone has lived in this way, so she alone has attained to this pitch of power. For joining with herself many States throughout Italy as her companions, who in most respects lived with her on a footing of equality, while, as has been noted, always reserving to herself the seat of empire and the titular command, it came about that these States, without being aware of it, by their own efforts, and with their own blood, wrought out their own enslavement.
For when Rome began to send armies out of Italy, for the purpose of reducing foreign kingdoms to provinces, and of subjugating nations who, being used to live under kings, were not impatient of her yoke, and who, receiving Roman governors, and having been conquered by armies bearing the Roman name, recognized no masters save the Romans, those companions of Rome who dwelt in Italy suddenly found themselves surrounded by Roman subjects, and weighed down by the greatness of the Roman power; and when at last they came to perceive the mistake in which they had been living, it was too late to remedy it, so vast was the authority which Rome had then obtained over foreign countries, and so great the resources which she possessed within herself; having by this time grown to be the mightiest and best-armed of States. So that although these her companions sought to avenge their wrongs by conspiring against her, they were soon defeated in the attempt, and remained in a worse plight than before, since they too became subjects and no longer associates. This method, then, as I have said, was followed by the Romans alone; but no other plan can be pursued by a republic which desires to extend its power; experience having shown none other so safe and certain.
