Such was his line of action as to present affairs. But as to the future he had to fear, in the first place, that a new successor to the Church might not be friendly to him and might seek to take from him that which Alexander had given him, so he decided to act in four ways. Firstly, by exterminating the families of those lords whom he had despoiled, so as to take away that pretext from the Pope. Secondly, by winning to himself all the gentlemen of Rome, so as to be able to curb the Pope with their aid, as has been observed. Thirdly, by converting the college more to himself. Fourthly, by acquiring so much power before the Pope should die that he could by his own measures resist the first shock. Of these four things, at the death of Alexander, he had accomplished three. For he had killed as many of the dispossessed lords as he could lay hands on, and few had escaped; he had won over the Roman gentlemen, and he had the most numerous party in the college. And as to any fresh acquisition, he intended to become master of Tuscany, for he already possessed Perugia and Piombino, and Pisa was under his protection. And as he had no longer to study France (for the French were already driven out of the kingdom of Naples by the Spaniards, and in this way both were compelled to buy his goodwill), he pounced down upon Pisa. After this, Lucca and Siena yielded at once, partly through hatred and partly through fear of the Florentines; and the Florentines would have had no remedy had he continued to prosper, as he was prospering the year that Alexander died, for he had acquired so much power and reputation that he would have stood by himself, and no longer have depended on the luck and the forces of others, but solely on his own power and ability.
