In the 19th century, the 7th duke's descendants ceased to pay their title inheritance taxes in Spain, and as a consequence the title became vacant, but was still recognised in the
Kingdom of Italy. In 1905, the Spanish king
Alfonso XIII rehabilitated the dukedom on behalf of Julio Quesada-Cañaveral, a descendant of the 3rd duke. The title was still claimed by the Italian descendants of the 7th duke, and so there continues to be an unrecognised pretender to the title in the Republic of Italy, where peerage titles are not officially recognized since 1948. ==See also==
