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
