THE \'.'ESTERN MEDITERRAI\EAN KINGDOMS 1200-1500directly in north Italian politics. Ludwig of Bavaria posed
a greater danger to the pope than to King Robert. He sur-
rounded himself with scholars critical of papal pretensions,
such as the political theorist Marsiglia of Padua and the phi-
losopher William of Ockham. He scorned papal excommun-
ication (1324); he appointed his own pope, the Spiritual
Franciscan Nicholas V, who was as a matter of fact a native
of Robert's kingdom (1328): a puppet pope, but a shrewd
choice, since John XXII had condemned the doctrine of the
'absolute poverty' of Christ and had persecuted the Spiritual
Franciscans who were its main proponents. Nicholas V then
crowned Ludwig as emperor, a title few of course recognised.
Robert of Anjou showed little sign of being greatly scared by
Ludwig, even when the emperor was crowned in Rome in
- He seems to have reasoned that wars in Tuscany would
 distract Ludwig from interference in Neapolitan affairs. An-
 other dimension to Robert's attitude was probably his irrita-
 tion atJohn XXII. Whether its source lay in the excessively
 vigorous attempts of this aggressive pope to guide Angevin
 policy, or whether it lay in Robert's affection for the Spiritual
 Franciscans whom John persecuted, the late 1320s saw the
 paths of Robert and John diverge.^17
 This is not to say that the Angevins failed to recognise
 the danger of a Ghibelline revival in Tuscany. The brilliant
 soldier Castruccio Castracani frequently, though not con-
 stantly, gained the upper hand in battles with the Guelfs. A
 whole series of victories brought Robert's enemies power
 and influence in the Romagna by 1315, and in Tuscany by
 1325; notable were the Ghibelline victories at Altopascio
 (May, 1325), and further north at Zappolino (November,
 1325). The Guelfs were increasingly on the defensive; even
 the Florentines thought they could only guarantee their
 liberties by accepting an Angevin governor. Robert had
 tried to foist one on them as long before as 1317, but the
 Florentines insisted that a royal vicar would be incompatible
 with their traditions of freedom. But in 1325 they offered
 the seigneury of the city to Robert's heir, Charles duke of
 Calabria. He was to bring with him several hundred knights,
 and he was to receive 100,000 florins per annum from the
