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.
Manrique were one of major Spanish aristocratic families of the Jewish converso descent. See, Norman Roth, "Conversos, Inquisition, and the Expulsion of the Jews from Spain", Madison, WI: The University of Wisconcin Press, 1995, p. 333. Jorge Manrique was a great-nephew of Iñigo López de Mendoza (marquess of Santillana), a descendant of Pero López de Ayala, chancellor of Castile, and a nephew of Gómez Manrique, corregidor of Toledo, all important poets of the late fourteenth and fifteenth centuries. He was, therefore, a member of a noble family of great consequence.
