Why the kingdom of Darius, which was conquered by Alexander, did not revolt against the successors of Alexander after his death

If we reflect upon the difficulties of preserving a newly acquired state, it seems marvellous that after the rapid conquest of all Asia by Alexander the Great, and his subsequent death, which one would suppose most naturally to have provoked the whole country to revolt, yet his successors maintained their possession of it, and experienced no other difficulties in holding it than such as arose amongst themselves from their own ambition.

I meet this observation by saying that all principalities of which we have any accounts have been governed in one of two ways; viz. either by one absolute prince, to whom all others are as slaves, some of whom, as ministers, by his grace and consent aid him in the government of his realm; or else by a prince and nobles, who hold that rank, not by the grace of their sovereign, but by the antiquity of their lineage. Such nobles have estates and subjects of their own, who recognise them as their liege lords, and have a natural affection for them.

In those states that are governed by an absolute prince and slaves, the prince has far more power and authority; for in his entire dominion no one recognises any other superior but him; and if they obey any one else, they do it as though to his minister and officer, and without any particular affection for such official. Turkey and France furnish us examples of these two different systems of government at the present time. The whole country of the Turk is governed by one master; all the rest are his slaves; and having divided the country into Sanjacs, or districts, he appoints governors for each of these, whom he changes and replaces at his pleasure.

But the king of France is placed in the midst of a large number of ancient nobles, who are recognised and acknowledged by their subjects as their lords, and are held in great affection by them. They have their rank and prerogatives, of which the king cannot deprive them without danger to himself. In observing now these two principalities, we perceive the difficulty of conquering the empire of the Turk, but once conquered it will be very easily held. The reasons that make the conquest of the Turkish empire so difficult are, that the conqueror cannot be called into the country by any of the great nobles of the state; nor can he hope that his attempt could be facilitated by a revolt of those who surround the sovereign; which arises from the above given reasons. For being all slaves and dependants of their sovereign, it is more difficult to corrupt them; and even if they were corrupted, but little advantage could be hoped for from them, because they cannot carry the people along with them.

Whoever therefore attacks the Turks must expect to find them united, and must depend wholly upon his own forces, and not upon any internal disturbances. But once having defeated and driven the Turk from the field, so that he cannot reorganise his army, then he will have nothing to fear but the line of the sovereign. This however once extinguished, the conqueror has nothing to apprehend from any one else, as none other has any influence with the people; and thus, having had nothing to hope from them before the victory, he will have nothing to fear from them afterwards.

The contrary takes place in kingdoms governed like that of France; for having gained over some of the great nobles of the realm, there will be no difficulty in entering it, there being always malcontents and others who desire a change. These, for the reasons stated, can open the way into the country for the assailant, and facilitate his success. But for the conqueror to maintain himself there afterwards will involve infinite difficulties, both with the conquered and with those who have aided him in his conquest. Nor will it suffice to extinguish the line of the sovereign, because the great nobles remain, who will place themselves at the head of new movements; and the conqueror, not being able either to satisfy or to crush them, will lose the country again on the first occasion that presents itself.

If now we consider the nature of the government of Darius [of persia], we shall find that it resembled that of the Turk, and therefore it was necessary for Alexander to attack him in full force, and drive him from the field. After this victory and the death of Darius, Alexander remained in secure possession of the kingdom for the reasons above explained. And if his successors had remained united, they might also have enjoyed possession at their ease; for no other disturbances occurred in that empire, except such as they created themselves.
