Duke of Alcalá de los Gazules

Duke of Alcalá de los Gazules (Duque de Alcalá de los Gazules), commonly known as Duke of Alcalá, is an hereditary title in the Peerage of Spain accompanied by the dignity of Grandee, granted in 1558 by Philip II to Pedro Afán de Ribera, 3rd Marquess of Tarifa, Lord of Alcalá de los Gazules and Viceroy of Naples and Catalonia.

History
The territory of the dukedom was a part of the Kingdom of Granada until 1264, when it was won by King Alfonso X of Castile. The Granadans had named the castle and its surrounding lands the Qalat at Yazula, Arabic for "Castle of the Gazules", from which its Spanish name is derived.
