The luck of Ladislaus of Durazzo

John of Gaunt and the Castillan Succession war
John of Gaunt and the end of a dynastic war On his marriage to Infanta Constance of Castile in 1371, John assumed (officially from 29 January 1372) the title of King of Castile and Leon in right of his wife, and insisted his fellow English nobles henceforth address him as 'my lord of Spain.' He impaled his arms with those of the Spanish kingdom. From 1372 John gathered around himself a small court of refugee Castilian knights and ladies and set up a Castilian chancery which prepared documents in his name according to the style of Pedro I of Castile, dated by the Castilian era and signed by himself with the Spanish formula 'Yo El Rey' (I, the King). He hatched several schemes to make good his claim with an army, but for many years these were still-born due to lack of finance or the conflicting claims of war in France or with Scotland. It was only in 1386, after Portugal under its new king John of Avis had entered into full alliance with England, that he was actually able to land with an army in Spain and mount an ultimately unsuccessful campaign for the throne of Castile. John sailed from England on 9 July 1386 with a huge Anglo-Portuguese fleet, carrying an army of about 5,000 men plus an extensive 'royal' household and his wife and daughters. Pausing on the journey to use his army to drive off the French forces who were then besieging Brest, he landed at Corunna in northern Spain on 29 July. The Castilian king, John of Trastámara, had expected Gaunt would land in Portugal and had concentrated his forces on the Portuguese border; he was wrong-footed by Gaunt's decision to invade Galicia, the most distant and disaffected of Castile's provinces. From August to October, John of Gaunt set up a rudimentary court and chancery at Orense and received the submission of most of the towns of Galicia, though they made their homage to him conditional on his being recognized as king by the rest of Castile. While John of Gaunt had gambled on an early decisive battle, the Castilians were in no hurry to join battle, and he began to experience difficulties keeping his army together and paying it. In November he met Joao I of Portugal at Ponte do Mouro on the south side of the Minho River and concluded an agreement with him to make a joint Anglo-Portuguese invasion of central Castile early in 1387. The treaty was sealed by the marriage of John's eldest daughter Philippa to the Portuguese King. A large part of John's army had succumbed to sickness, however, and when the invasion was mounted they were far outnumbered by their Portuguese allies. The campaign (April–June 1387) was an ignominious failure. The Castilians refused to offer battle and the Anglo-Portuguese troops, apart from time-wasting sieges of fortified towns, were reduced to foraging for food in the arid Spanish landscape. They were harried mainly by French mercenaries of the Castilian King. Many hundreds of English, including close friends and retainers of John of Gaunt, died of disease or exhaustion. Many deserted or abandoned the army to ride north under French safe-conducts. Shortly after the army returned to Portugal, John of Gaunt refused the truce with John of Trastamara and he cursed John of Trastamara and he had his own daughter, Catherine married to Ladislao of Durazzo after a negotiation with Charles III of Naples which later sparks a Spanish succession war.

Capetian House of Anjou

Charles III of Naples was the son of Louis of Durazzo and Margaret of Sanseverino. As the great-grandchild of King Charles II of Naples, he was a second cousin to Queen Joan I (both agnatically) and also adopted by her as a child, since he was the only male of the senior Angevin line of Sicily. Joan I was infatuated with him throughout her life. However, much to her displeasure, her romantic interest in him was never requited. In 1369 he married Margaret of Durazzo, the daughter of Joan's younger sister Marie, and his own first cousin. The conflict between Joan and Pope Urban VI caused the Pope (as feudal overlord of the kingdom) to declare her dethroned in 1381 and give the kingdom to Charles III of Naples. He marched on the Kingdom of Naples with a Hungarian army, defeated the King Consort Otto, Duke of Brunswick-Grubenhagen at San Germano, seized the city and besieged her in the Castel dell'Ovo. After Otto's failed attempt to relieve her, Charles captured her and had her imprisoned at San Fele. Soon afterwards, when reached by news that her adopted heir, Louis I of Anjou, was setting an expedition to conquer back Naples, Charles III of Naples had the Queen strangled in prison in 1382. Then he succeeded to the crown. Louis's expedition counted to some 40,000 troops, including those of Amadeus VI of Savoy, and had the financial support of Antipope Clement VII and Bernabò Visconti of Milan. Charles, who counted on the mercenary companies under John Hawkwood and Bartolomeo d'Alviano, for a total of some 14,000 men, was able to divert the French from Naples to other regions of the kingdom and to harass them with guerrilla tactics. Amadeus fell ill and died in Molise on 1 March 1383, and his troops abandoned the field. Louis asked for help to his king in France, who sent him an army under Enguerrand VII, Lord of Coucy. The latter was able to conquer Arezzo and then invade the Kingdom of Naples, but midway was reached by the news that Louis had suddenly died at Bisceglie on 20 September 1384. He decided to conquer Provence back he succeeded in getting Provence back with the help of the Pope Urban VI and the Antipope Clement VII is deposed and the church reunited and the Valois-Anjou now would just stay in Anjou and the island of Sicily is annexed by Charles III.
