Duke of Almazán de Saint Priest (es|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.[2]
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.[3] [4] 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.
