Ferdinand (1189 – 14 October 1211) was an infante (royal prince), the second son and heir apparent of Alfonso VIII of Castile by his wife, Eleanor of England. He died unmarried at the age of 22, a little less than three years before his father. Alfonso's first will, drawn up in 1204, named Ferdinand as heir to the throne and named his mother as his regent during his minority. The chroniclers are unanimous in praising Ferdinand's strength, beauty, piety and crusading zeal. According to the Chronicon mundi of the historian Lucas de Tuy, he wanted to expel all the Jews from Spain.
