But it is in the new monarchy that difficulties really exist. Firstly, if it is not entirely new, but a member as it were of a mixed state, its disorders spring at first from a natural difficulty which exists in all new dominions, because men change masters willingly, hoping to better themselves; and this belief makes them take arms against their rulers, in which they are deceived, as experience shows them that they have gone from bad to worse. This is the result of another very natural cause, which is the necessary harm inflicted on those over whom the prince obtains dominion, both by his soldiers and by an infinite number of other injuries unavoidably caused by his occupation. Thus you find enemies in all those whom you have injured by occupying that dominion, and you cannot maintain the friendship of those who have helped you to obtain this possession, as you will not be able to fulfil their expectations, nor can you use strong measures with them, being under an obligation to them; for which reason, however strong your armies may be, you will always need the favour of the inhabitants to take possession of a province. It was from these causes that Louis XII. of France, though able to occupy Milan without trouble, immediately lost it, and the forces of Ludovico alone were sufficient to take it from him the first time, for the inhabitants who had willingly opened their gates to him, finding themselves deluded in the hopes they had cherished and not obtaining those benefits that they had anticipated, could not bear the vexatious rule of their new prince.
