Jorge Manrique (c. 1440 – 1479) was a major Spanish poet, whose main work, the "Coplas a la muerte de su padre (Stanzas about the Death of his Father)", is still read today. He was a supporter of the great Spanish 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 after Isabel gained the crown.
