Yet Paul was a man of the elder generation. It could not be expected that a Pope of the Renaissance should suddenly abandon the mediaeval policy of Papal hostility to the Empire, especially when the Empire was in the hands of so omnipotent a master as Charles. It could not be expected that he should recognize the wisdom of confining Papal ambition to ecclesiastical interests, and of forming a defensive and offensive alliance with Catholic sovereigns for the maintenance of absolutism. It could not be expected that he should forego the pleasures and apparent profits of creating duchies for his bastards, whereby to dignify his family and strengthen his personal authority as a temporal sovereign. It is true that the experience of the last half century had pointed in the direction of all these changes; and it is certain that the series of events connected with the Council of Trent, which began in Paul III.'s reign, rendered them both natural and necessary. Yet Paul, as a man of the elder generation filling the Papal throne for fifteen years during a period of transition, adhered in the main to the policy of his predecessors. It was fortunate for him and for the Holy See that the basis of his character was caution combined with tough tenacity of purpose, capacity for dilatory action, diplomatic shiftiness and a political versatility that can best be described by the word trimming. These qualities enabled him to pass with safety through perils that might have ruined a bolder, a hastier, or a franker Pope, and to achieve the object of his heart's desire, where stronger men had failed, in the foundation of a solid duchy for his heirs. Paul's jealousy of the Spanish ascendancy in Italian affairs caused him to waver between the Papal and Imperial, Guelf and Ghibelline, parties. These names had lost much of their significance; but the habit of distinction into two camps was so rooted in Italian manners, that each city counted its antagonistic factions, maintained by various forms of local organization and headed by the leading families.[15] Burigozzo, under the year 1517, tells how the whole population of Milan was divided between Guelfs and Ghibellines, wearing different costumes; and it is not uncommon to read of petty nobles in the country at this period, who were styled Captains of one or the other party.
