vanquished, they tend to a coalition; and powerful nations considering a province, or a fortress acquired on their frontier, as so much gained, are perpetually intent on extending their limits.
The maxims of conquest are not always to be distinguished from those of self defence. If a neighbouring state be dangerous, if it be frequently troublesome, it is a maxim founded in the consideration of safety, as well as of conquest, that it ought to be weakened or disarmed: if, being once reduced, it be disposed to renew the contest, it must from thenceforward be governed in form. Rome never avowed any other maxims of conquest; and she every where sent her insolent armies under the specious pretence of procuring to herself and her allies a lasting peace, which she alone would reserve the power to disturb.
The equality of those alliances which the Grecian states formed against each other, maintained, for a time, their independence and separation; and that time was the shining and the happy period of their story. It was prolonged more by the vigilance and conduct which they severally applied, than by the moderation of their councils, or by any peculiarities of domestic policy which arrested their progress. The victors were sometimes contented, with merely changing to a resemblance of their own forms, the government of the states they subdued. What the next step might have been in the progress of impositions, is hard to determine. But when we consider, that one party fought for the imposition of tributes, another for the ascendant in war, it cannot be doubted, that the Athenians, from a national ambition, and from the desire of wealth; and the Spartans, though they originally only meant to defend themselves, and their allies, were both, at last, equally willing to become the masters of Greece; and were preparing for each other at home that yoke, which both, together with their confederates, were obliged to receive from abroad.
In the conquests of Philip, the desire of self-preservation and security seemed to be blended with the ambition natural to princes. He turned his arms successively to the quarters on which he found himself hurt, from which he had been alarmed or provoked; and when he had subdued the Greeks, he proposed to lead them against their ancient enemy of Persia. In this he laid the plan which was carried into execution by his son.
The Romans, become the masters of Italy, and the conquerors of Carthage, had been alarmed on the side of Macedon, and were led to cross a new sea in search of a new field, on which to exercise their military force. In prosecution of their wars, from the earliest to the latest date of their history, without intending the very conquest they made, perhaps without foreseeing what advantage they were to reap from the subjection of distant provinces, or in what manner they were to govern their new acquisitions, they still proceeded to seize what came successively within their reach; and, stimulated by a policy which engaged them in perpetual wars, which led to perpetual victory and accessions of territory, they extended the frontier of a state, which, but a few centuries before, had been confined within the skirts of a village, to the Euphrates, the Danube, the Weser, the Forth, and the Ocean.
It is vain to affirm that the genius of any nation is adverse to conquest. Its real interests indeed most commonly are so; but every state, which is prepared to defend itself, and to obtain victories, is likewise in hazard of being tempted to conquer.
