Prince of Spain
Prince of Spain, was the title created on 22 July 1969 designated by law proclaiming Juan Carlos de Borbón as the successor of Francisco Franco. Juan Carlos held the title until 22 November 1975, when he became King of Spain following the death of Franco. The only person to hold this title was Juan Carlos; the title given to the heir to the Spanish throne has since been Prince of Asturias.
The title was given the associated style of His Royal Highness and the military honors of the Captain General of the Army. The design of the coat of arms and the royal standard was regulated by decree on 22 April 1971 for the personal use by the Prince of Spain, not to be confused with an earlier hereditary confirmation by Joseph Bonaparte on his children and grandchildren.
