His inability to resist the demands of his nobles left a heritage of trouble in Aragon. By recognising their right to rebel in the articles called the Union he helped to make anarchy permanent.
Pope Calixtus III (December 31, 1378–August 6, 1458), né Alfons de Borja, was born near Xàtiva, València, today Spain but then Kingdom of Valencia under the Crown of Aragon, and was Pope from April 8, 1455 to his death.
He was raised to the papal chair in 1455 as Calixtus III at a very advanced age as a compromise candidate.
Calixtus III's papal bull of June 29, 1456, which called for public prayer for the success of the crusade, makes no mention of the comet, and by August 6, when the Turkish siege was broken, the comet had not been visible for several weeks.
Alfons or Alfonso III of Aragon (1265 – June 18, 1291, also Alfons II of Barcelona), surnamed the Liberal, was the king of Aragon and count of Barcelona from 1285 to 1291.
He was a son of Peter III of Aragon and his Queen consort Constance of Sicily, daughter and heiress of Manfred of Sicily.
For this reason, probably, Dante Alighieri, in the Divine Comedy, recounts that he saw Alfonso's spirit seated outside the gates of Purgatory with the other monarchs whom Dante blamed for the chaotic political state of Europe during the 13th century.
