1911 Encyclopædia Britannica/John II. of Castile
JOHN II. (1405–1454), king of Castile, was born on the 6th of March 1405, the son of Henry III. of Castile and of his wife Catherine, daughter of John of Gaunt. He succeeded his father on the 25th of December 1406 at the age of a year and ten months. It was one of the many misfortunes of Castile that the long reign of John II.—forty-nine years—should have been granted to one of the most incapable of her kings. John was amiable, weak and dependent on those about him. He had no taste except for ornament, and no serious interest except in amusements, verse-making, hunting and tournaments. He was entirely under the influence of his favourite, Alvaro de Luna, till his second wife, Isabella of Portugal, obtained control of his feeble will. At her instigation he threw over his faithful and able favourite, a meanness which is said to have caused him well-deserved remorse. He died on the 20th of July 1454 at Valladolid. By his second marriage he was the father of Isabella “the Catholic.”
