Parent house

Origin

Henry, Count of Trastámara, was a natural son of Alfonso XI of Castile and Eleanor de Guzmán. In his struggle against his half-brother Peter I, the Castilian civil war intersected with the Hundred Years’ War: Henry received French support and Peter English support. Peter’s death at Montiel in 1369 gave Henry II the throne.

Development

John I and Henry III consolidated the dynasty in Castile. In 1412 the Compromise of Caspe elected Ferdinand of Antequera, John I’s son, King of Aragon. The Aragonese branch expanded to Naples under Alfonso V. John II of Aragon was also King of Navarre through his marriage to Blanche I. Ferrante’s Neapolitan branch continued as a separate dynasty until 1501.

Legacy

The marriage of Isabella of Castile and Ferdinand of Aragon in 1469 brought together the two principal branches in the same couple while their kingdoms remained distinct. The deaths of their heirs brought the succession to their daughter Joanna and, through her, to the Habsburgs. The house marks the transition from medieval crowns to the composite Spanish Monarchy.
