John was the son of King Henry III and his wife, Catherine of Lancaster. His mother was the granddaughter of King Peter, who was ousted by Henry III’s grandfather, King Henry II. John succeeded his father on 25 December 1406, and united in his person the claims of both Peter and Henry II. His mother and his uncle, King Ferdinand I of Aragon, were co-regents during his minority. When Ferdinand died in 1416, his mother governed alone until her death in 1418.  John II’s reign, lasting 49 years, was one of the longest in Castilian history, but John himself was not a particularly capable monarch. He spent his time verse-making, hunting, and holding tournaments. His favourite, Álvaro de Luna, heavily influenced him until his second wife, Isabella of Portugal, obtained control of his feeble will. At her instigation, he dismissed his faithful and able servant, an act which is said to have caused him much remorse.  John II declared the Valladolid laws in 1411, which restricted the social activity of Jews. Among the most notable of the provisions were outlining that Jews must wear distinctive clothes and banned them from holding administrative positions.  In 1431 John placed Yusuf IV on the throne of the Moorish kingdom of Granada, in exchange for tribute and vassal status to Castile. This exchange is depicted in the short ballad the Romance of Abenamar.  He was “[T]all and handsome, fair-skinned and slightly ruddy… his hair was the color of a very mature hazelnut, the nose a little snub, the eyes between green and blue… he had very graceful legs and feet and hands.”  John died on 20 July 1454, at Valladolid.  In 1418, John married Maria of Aragon, the oldest daughter of his paternal uncle, Ferdinand I of Aragon. Of all their children, only the future Henry IV of Castile survived infancy. John was widowed in 1445 and remarried to Isabella of Portugal, daughter of Infante John of Portugal.
