About Jorge Manrique:
Jorge Manrique is still read today. He was a supporter of the great queen, Isabel I of Castile, and actively participated on her side in the civil war that broke out against her half-brother, Enrique IV, when the latter attempted to make his daughter, Juana, crown princess. Jorge died in 1479 during an attempt to take the castle of Garcimuñoz, defended by the Marquis of Villena (a staunch enemy of Isabel), after Isabel gained the crown.
