The scenes of the uprising were the outskirts of Huesca, with the Loarre castle as the main square defended by Antón de Luna; the surroundings of Buñol, fortress belonging to the count of Urgell and Balaguer, the capital of his county.

Although James believed that his rights were preeminent, once it had been established that the transmission of the royal succession was legitimate through the female route, the issue was simplified by comparing the degree of consanguinity of the suitors with Martin I of Aragon.

The scenes of his revolt were northern Aragón (traditional fiefdom of Antón de Luna), Balaguer in the county of Urgell (belonging to his solar house) and Buñol in Valencia , a manor of his.

Ferdinand I and his advisors had a favorable deal with James II of Urgell that took the form of territorial and economic concessions for him, his wife Isabellla and his mother Margarita de Montferrat.

However, the instigation of some faithful counselors and nobles, such as the Aragonese Antón de Luna, encouraged him to revolt in May 1413 against the king with the support of mercenarys English and Gascones, who fought in the Hundred Years' War, while the Cortes of 1413, according to his account in his Anales (1562-1580) Jerónimo Zurita with the support of Tomás de Clarencia, son of the king of England, who offered a thousand knights and three thousand archers, in exchange for the Kingdom of Sicily, which would be guaranteed with the wedding with one of the sisters by James of Urgell.

The deputies, frightened by the news of a revolt in the countryside and unwilling to return to a situation of political uncertainty that had already lasted two years, ran to close ranks with what, despite everything, was the new king recognized by everyone.

[11] Upon hearing the news of the proclamation of Fernando de Antequera as king of Aragon, James II of Urgell was incredulous, and took refuge in his castle of Balaguer without wanting to go to the Cortes of Aragón that were going to meet in Zaragoza starting on August 25, 1412 in order for the king to swear the Fueros of Aragon before the Cortes of the kingdom with witnesses representing the entire Crown (the archbishop of Cagliari, the Count of Cardona—prominent Urgellist before the proclamation of the new king—or Ramón Fivaller) despite the fact that the former had been invited to this solemn meeting.

At that point in Fernando's reign, when it had already been accepted by almost everyone, this decision is described by Vicens Vives as a sterile revolt and by Santiago y Sobrequés as "fora de temps", since Ferdinand I represented constitutionality, order and public peace and the Count of Urgell altered all this with his rebellion.

[15] He had the Loarre castle, from where five hundred knights and some companies of mercenary archers from Basil of Genoa and Menaut de Favars recruited among the Gascon troops that supported the interests in this region of the king of England, they carried out isolated military episodes north of Huesca.

[25] James was imprisoned and thus began a long exile, which passed through the castle of Urueña (1414-1420), Mora (1420-1422) , Alcázar of Madrid (1422-1424), Castro Torafe, Zamora (1424-1426), Teruel and finally in Játiva ( 1426-1433),[26] in a more dignified seclusion at the request of Alfonso V the Magnanimous, son of Ferdinand I, where he died on 1 June 1433.
