Catherine of Castile (Castilian: Catalina de Castilla; 5 October 1422 - 17 September 1424) was suo jure Princess of Asturias and heiress presumptive to the Castilian throne all her life.
Catherine was born on 5 October 1422 in Illescas, Toledo. She was the first child of King John II of Castile and his first wife, Maria of Aragon. Named after her aunt and grandmother, the Duchess of Villena and Catherine of Lancaster, she immediately became heiress presumptive to the throne of Castile upon her birth. The Infanta was formally recognised as successor to the throne of the kingdom and sworn in as Princess of Asturias on 1 January 1423 by the Cortes of Toledo.Instituto Salazar Y Castro: Tratado de genealogia, héràldica y derecho nobiliario: segundo curso de la Escuela de Genealogía, Heráldica y Nobiliaria]; Ediciones Hidalguia, 2001, 8489851336
However, the Princess of Asturias did not live long enough to succeed her father as Queen of Castile. She died in Madrigal de las Altas Torres on 17 September 1424. Her younger sister, Infanta Eleanor, replaced her as heiress and Princess of Asturias. Princess Catherine is buried in Miraflores Charterhouse, along with her father and stepmother, Isabella of Portugal.Pedro Aguado Bleye, Cayetano Alcazar Molina: Manual de historia de España: Prehistoria.
