A desire for conquest is one of the most evident and dangerous causes of this increase. This desire, occasioned often by a different species of ambition from that which, it seems to proclaim, is not always what it appears to be, and has not so much, for its real motive, the apparent desire to aggrandise the Nation as a secret desire to increase the authority of the rulers at home, by increasing the number of troops, and by the diversion which the objects of war occasion in the minds of the citizens. It is at least certain, that no peoples are so oppressed and wretched as conquering nations, and that their successes only increase their misery. Did not history inform us of the fact, reason would suffice to tell us that, the greater a State grows, the heavier and more burdensome in proportion its expenses become: for every province has to furnish its share to the general expense of government, and besides has to be at the expense of its own administration, which is as great as if it were really independent. Add to this that great fortunes are always acquired in one place and spent in another. Production therefore soon ceases to balance consumption, and a whole country is impoverished merely to enrich a single town. Another source of the increase of public wants, which depends on the foregoing, is this. There may come a time when the citizens, no longer looking upon themselves as interested in the common cause, will cease to be the defenders of their country, and the Magistrates will prefer the command of mercenaries to that of free-men; if for no other reason than that, when the time comes, they may use them to reduce free-men to submission. Such was the state of Rome towards the end of the Republic and under the Emperors: for all the victories of the early Romans, like those of Alexander, had been won by brave citizens, who were ready, at need, to give their blood in the service of their country, but would never sell it. Only at the siege of Veii did the practice of paying the Roman infantry begin. Marius, in the Jugurthine war, dishonoured the legions by introducing freedmen, vagabonds and other mercenaries. Tyrants, the enemies of the very people it was their duty to make happy, maintained regular troops, apparently to withstand the foreigner, but really to enslave their countrymen. To form such troops, it was necessary to take men from the land; the lack of their labour then diminished the amount of provisions, and their maintenance introduced those taxes which increased prices. This first disorder gave rise to murmurs among the people; in order to suppress them, the number of troops had to be increased, and consequently the misery of the people also got worse; and the growing despair led to still further increases in the cause in order to guard against its effects. On the other hand, the mercenaries, whose merit we may judge of by the price at which they sold themselves, proud of their own meanness, and
