said, being
poor and scattered, cannot hurt. Upon this, one has to remark that men
ought either to be well treated or crushed, because they can avenge
themselves of lighter injuries, of more serious ones they cannot;
therefore the injury that is to be done to a man ought to be of such a
kind that one does not stand in fear of revenge.

But in maintaining armed men there in place of colonies one spends much
more, having to consume on the garrison all the income from the
state, so that the acquisition turns into a loss, and many more are
exasperated, because the whole state is injured; through the shifting
of the garrison up and down all become acquainted with hardship, and
all become hostile, and they are enemies who, whilst beaten on their
own ground, are yet able to do hurt. For every reason, therefore, such
guards are as useless as a colony is useful.

Again, the prince who holds a country differing in the above respects
ought to make himself the head and defender of his less powerful
neighbours, and to weaken the more powerful amongst them, taking care
that no foreigner as powerful as himself shall, by any accident, get
a footing there; for it will always happen that such a one will be
introduced by those who are discontented, either through excess of
ambition or through fear, as one has seen already. The Romans were
brought into Greece by the Aetolians; and in every other country where
they obtained a footing they were brought in by the inhabitants. And the
usual course of affairs is that, as soon as a powerful foreigner enters
a country, all the subject states are drawn to him, moved by the hatred
which they feel against the ruling power. So that in respect to those
subject states he has not to take any trouble to gain them over to
himself, for the whole of them quickly rally to the state which he has
acquired there. He has only to take care that they do not get hold of
too much power and too much authority, and then with his own forces, and
with their goodwill, he can easily keep down the more powerful of them,
so as to remain entirely master in the country. And he who does not
properly manage this business will soon lose what he has acquired, and
whilst he does hold it he will have endless difficulties and troubles.

The Romans, in the countries which they annexed, observed closely these
measures; they sent colonies and maintained friendly relations with(*)
the minor powers, without increasing their strength;
