For some time past, in truth, Italian politics had showed signs of approaching to a radical change. Frederic II., although often cruelly despotic, had gathered about him, nevertheless, all the most cultured men of the country and was highly popular among them. His successor, Manfred, was an adventurous and unfortunate prince, whose loftiness of spirit deservedly gained him numerous admirers. It is true that the Papacy had combated both in their quality of Ghibellines; but the policy of Rome was gradually becoming no less hostile to communal freedom than to the Ghibelline cause, inasmuch as the Papal ambition daily increased and sought to strengthen the temporal power at the expense of the communes. Florence still remained Guelph; but with changed times the character and value, if not the names of parties were beginning to suffer alteration throughout Italy. Hence men often changed sides with small hesitation, nor was it always easy to say whether those who deserted their own party had changed, or whether the alteration of the party itself had caused it to be forsaken. Also the general confusion was greatly increased now that the Popes, with their usual anxiety and dread of losing their supremacy in Italy, resolved on calling fresh strangers to their aid and thus drew fresh miseries on the land. Alarmed by the great power and reputation gained by the Swabian line, they sought defence in the course of policy so well described by Machiavelli when he remarks that the Popes, "sometimes for the love of religion, at others to forward their own ambitions, never ceased to call fresh humours into Italy and stir fresh wars. And no sooner had they raised a prince to power than they repented and sought to compass his ruin, nor would they consent that any province their own weakness prevented them from seizing should be possessed by another."[282] Thus, after many persistent intrigues, they finally decided the Angevins to undertake an expedition against Manfred, and for the conquest of the Neapolitan kingdom.
