Page "Charles I of Naples" Paragraph 18

In November 1272, the strained relations between Charles and Ghibelline-ruled Genoa finally broke into war.

Ghibelline revolts broke out across the north of Italy, and increasingly occupied the attention of Charles, even as Michael Palaeologus was negotiating a union of churches with the Pope.

At the same time, he had made contact with Genoa and was sending money to encourage the revolts in the north.

At the apparently successful conclusion of the Council of Lyon, a Union of Churches was declared, and Charles and Philip of Courtenay were compelled to extend a truce with Michael.

This was a blessing in disguise for Charles, for the Ghibellines now controlled most of the north, and he was forced to retreat from Piedmont in late 1275.

In truth, Pope Gregory was not entirely displeased ; he regarded north Italy as best dealt with by its new Emperor, Rudolph of Habsburg, and preferred that Charles be confined to the south.

If he wished to make war, let him look to Outremer ; and to this end, Gregory endorsed the sale to Charles of the claims of Maria of Antioch on the Kingdom of Jerusalem, which had been rejected by the Haute Cour there.

On 18 March 1277, he bought her claim and assumed the title of King of Jerusalem, sending Roger of San Severino as his bailli to Acre.

There Roger ousted Balian of Ibelin, the bailli of Hugh III and compelled the nobles to swear fealty.

In the meantime, Gregory had been succeeded by Pope Innocent V, who arranged a peace between Charles and the Genoese.
