Duke of Medinaceli

Duke of Medinaceli is an hereditary title in the peerage of Spain, accompanied by the dignity of Grandee. The Catholic Monarchs, Ferdinand II of Aragon and Isabella I of Castile, created the title and awarded it on 31 October 1479 to  Luis de la Cerda y de la Vega. He also held the title of 5th Count of Medinaceli, which was first awarded in 1368 to his ancestor, Bernal de Foix.

History
In 1368, the King of the Crown of Castile bestowed the title of Count of Medinaceli on Bernal de Foix, the second husband of Isabel de la Cerda.
