Duke of Cádiz

History

Rodrigo Ponce de León was a Castilian military leader who was granted the title of Duke of Cádiz in 1484. After the death of the first duke in 1492, the Catholic Monarchs negotiated with Francisca Ponce de León y de la Fuente regarding the abolition of the Marquisate and Duchy of Cádiz, reinstating the city and the titles to the crown after her death.

For centuries, the title remained in abeyance, until the nineteenth century. Since then, the title was held by members of the Spanish branch of the House of Bourbon.
