united, and he will have to rely more on his own strength than on the
revolt of others; but, if once the Turk has been conquered, and routed
in the field in such a way that he cannot replace his armies, there
is nothing to fear but the family of this prince, and, this being
exterminated, there remains no one to fear, the others having no credit
with the people; and as the conqueror did not rely on them before his
victory, so he ought not to fear them after it.

The contrary happens in kingdoms governed like that of France, because
one can easily enter there by gaining over some baron of the kingdom,
for one always finds malcontents and such as desire a change. Such men,
for the reasons given, can open the way into the state and render the
victory easy; but if you wish to hold it afterwards, you meet with
infinite difficulties, both from those who have assisted you and from
those you have crushed. Nor is it enough for you to have exterminated
the family of the prince, because the lords that remain make themselves
the heads of fresh movements against you, and as you are unable either
to satisfy or exterminate them, that state is lost whenever time brings
the opportunity.

Now if you will consider what was the nature of the government of
Darius, you will find it similar to the kingdom of the Turk, and
therefore it was only necessary for Alexander, first to overthrow him in
the field, and then to take the country from him. After which victory,
Darius being killed, the state remained secure to Alexander, for the
above reasons. And if his successors had been united they would have
enjoyed it securely and at their ease, for there were no tumults raised
in the kingdom except those they provoked themselves.

But it is impossible to hold with such tranquillity states constituted
