Enrique IV Blanco 
Enrique IV (Henry) was born January 25, 1425, Valladolid, Castile, Spain. He ruled as king of Castile from 1454 to 1474, though at first promising, his reign quickly became chaotic. Henry’s weak father, John II, was entirely under the control of his constable, Álvaro de Luna, who gave the young Henry a separate court at Segovia, hoping to control him. Instead, Henry worked with other advisors, resulting I the overthrowing Luna and his execution in 1453. In 1464 Henry reconquered Gilbralter from the Muslims. Henry IV’s first marriage was childless and ended in divorce. He then married a Portuguese princess Joana, who bore a daughter, Juana 'La Beltraneja’. One faction recognized Henry’s younger half-brother Alfonso, deposing Henry in effigy in the “Farce of Avila.” After three years of civil war Alfonso died, and Henry vacillated about the claim of his infant daughter. His rivals then recognized his half-sister, Isabella (the future Isabella I), who, without Henry’s knowledge or consent, married the heir to the throne of Aragon, Ferdinand (the future Ferdinand II). The two would one day rule a united Spain
