Duke of Almazán de Saint Priest

Duke of Almazán de Saint Priest (Duque de Almazán de Saint Priest), is a title of Spanish nobility that is accompanied by the dignity of Grandee of Spain. It was granted to Emmanuel Louis Guignard de Saint-Priest on 30 September 1830 by King Ferdinand VII.

At the death of the 3rd Duchess, the title became vacant, until Juan Carlos I rehabilitated it on behalf of Louis Provence Boniface de Castellane, a direct descendant of the 3rd Duchess, on 22 January 1993. Initially created as "Duke of Almazán", it was rehabilitated as "Duke of Almazán de Saint Priest", in order to differentiate it from the older Dukedom of Almazán.
