The Prince who establishes himself in a Province whose laws and language differ from those of his own people, ought also to make himself the head and protector of his feebler neighbours, and endeavour to weaken the stronger, and must see that by no accident shall any other stranger as powerful as himself find an entrance there. For it will always happen that some such person will be called in by those of the Province who are discontented either through ambition or fear; as we see of old the Romans brought into Greece by the Aetolians, and in every other country that they entered, invited there by its inhabitants. And the usual course of things is that so soon as a formidable stranger enters a Province, all the weaker powers side with him, moved thereto by the ill-will they bear towards him who has hitherto kept them in subjection. So that in respect of these lesser powers, no trouble is needed to gain them over, for at once, together, and of their own accord, they throw in their lot with the government of the stranger. The new Prince, therefore, has only to see that they do not increase too much in strength, and with his own forces, aided by their good will, can easily subdue any who are powerful, so as to remain supreme in the Province. He who does not manage this matter well, will soon lose whatever he has gained, and while he retains it will find in it endless troubles and annoyances.
