Compromise of Caspe

J. N. Hillgarth writes: "Among the descendants by the male line, the closest relation to Martin was James II, Count of Urgell.

"[1] T. N. Bisson writes that "the issue was (or became) political rather than simply legal, a utilitarian question of which candidate with some dynastic claim would make the best king.

"[2] The major candidates for succession were: The parties had agreed to a parliamentary process to resolve the issue, but coordinating deliberations between the cortes (parliaments) of Aragon, Valencia and Catalonia was made difficult by their diverging interests.

[21] Vincent Ferrer was the first one to speak; in a long speech, he voted for Ferdinand, and then Ram, his brother Bonifaci, Gualbes, Bardaixí, and Aranda simply joined him.

[25] In recent years, three Aragonese historians (José Ángel Sesma Muñoz, Carlos Laliena, and Cristina Monterde) rejected Zurita's account, arguing that no contemporary sources confirm the existence of any secret ballot.

[27] Their main argument is that the official notarized deed of proclamation, issued on 25 June 1412, does not mention any results of the supposed election.

Furthermore, they quoted testimonies (but not the full statements) from those who were present at the ceremony of proclamation on 28 June, such as Melchor de Gualbes, saying that the three Catalan compromisarios had declared that "they had acted freely and had not been under any pressure" and that at the end "everybody would be of one opinion".

He also mentioned that even Trastamara's official chronicler Lorenzo Valla said in the 15th century that there were very different opinions among the compromisarios.

Antón de Luna enlisted the support of Gascon and English troops who invaded at Jaca, but they were defeated on 10 July 1413 before he was able to join James's army.

With the selection of a younger prince of the Castilian Royal House of Trastámara, the Aragonese Crown became increasingly drawn into the sphere of influence of the more powerful Castile.
