Ferdinand I (Portuguese: Fernando;[1]31 October 1345 – 22 October 1383), sometimes called the Handsome (o Formoso or o Belo ) or occasionally the Inconstant (o Inconstante), was the King of Portugal and the Algarve from 1367 until his death.
Life
Ferdinand was born in Lisbon, the second but eldest surviving son of Peter I and his wife, Constance of Castile.[2] On the death of Peter of Castile in 1369, Ferdinand, as great-grandson of Sancho IV by the female line, laid claim to the vacant Castilian throne. The kings of Aragon and Navarre, and later John of Gaunt, Duke of Lancaster, who had married Petter of Castile's eldest daughter, Constance, also claimed the throne.
The throne was held by Henry of Trastámara (Henry II of Castile), Peter of Castile's illegitimate brother, who had defeated him in the Castilian Civil War in 1366 and assumed the crown. After one or two indecisive campaigns, all parties were ready to accept the mediation of Pope Gregory XI. The conditions of the treaty, ratified in 1371, included a marriage between Ferdinand and Leonora of Castile. But before the union could take place Ferdinand had become passionately attached to Leonor Telles de Meneses, the wife of one of his own courtiers. Having procured a dissolution of her previous marriage, he lost no time in making Leonor his queen.[2]
This conduct, although it raised a serious insurrection in Portugal, did not at once result in a war with Henry. However, the outward concord was soon disturbed by intrigues with the Duke of Lancaster, who entered into a secret treaty with Ferdinand for the expulsion of Henry from his throne. The war which followed was unsuccessful; and peace was again made in 1373.
On the death of Henry in 1379, the Duke of Lancaster once more put forward his claims, and again found an ally in Portugal. According to the Continental annalists, the English proved as offensive to their allies as to their enemies in the field. So Ferdinand made a peace for himself at Badajoz in 1382. It stipulated that Beatrice, Ferdinand's daughter and heiress, would marry King John I of Castile, and thus secure the ultimate union of the two crowns.
Ferdinand left no male heir when he died at Lisbon on 22 October 1383, and the direct Burgundian line, which had been in possession of the throne since the days of Count Henry (about 1112), became extinct. The stipulations of the treaty of Badajoz were set aside, and John, Grand Master of the order of Aviz, Ferdinand's illegitimate brother, claimed the throne. This led to a period of war and political indefinition known as the 1383-1385 Crisis. John became the first king of the House of Aviz in 1385.
Marriages and descendants
Fernando married Leonor Telles (or Teles) de Meneses, formerly the wife of the late nobleman João Lourenço da Cunha, Lord of Pombeiro, and daughter of Martim Afonso Teles de Meneses. She bore him two sons, who both died young, and one daughter.
