SANTILLANA, Iñigo Lopez de Mendoza, Marquis of (1398-1458), Castilian poet, was born at Carrion de los Condes in Old Castile on August 19, 1398. His father, Don Diego Hurtado de Mendoza, grand admiral of Castile, having died while Inigo was still quite young, the boy was brought up by his uncle Don Alfonso Enriquez. From his twentieth year onwards he became an increasingly prominent figure at the court of Juan II. of Castile, distinguishing himself both in civil and military service; he was created Marques de Santillana and Conde del Real do Manzanares for the part he took in the battle of Olmedo in 1445. In the protracted struggle of the Castilian nobles against the preponderating influence of Alvaro de Luna he showed great moderation, but ultimately in 1452 he joined the combination which effected the fall of the favourite in the following year. From the death of Juan II. in 1454 Mendoza took little part in public affairs, devoting himself mainly to the pursuits of literature and to pious meditation. He died at Guadalajara on March 26, 1458....
