Prince Pedro, Duke of Calabria
Prince Pedro of Bourbon-Two Sicilies, Duke of Calabria (Spanish: "Pedro Juan María Alejo Saturnino y de Todos los Santos"; born 16 October 1968), is the only son of Infante Carlos, Duke of Calabria (1938–2015), and his wife, Princess Anne of Orléans. He is a claimant to the headship of the House of Bourbon-Two Sicilies, which ruled the Kingdom of the Two Sicilies before the unification of Italy. Claim and career. The only son of Infante Carlos, Duke of Calabria (1938–2015), and his wife, Princess Anne of Orléans. Pedro is currently one of two  claimants to the headship of the House of Bourbon-Two Sicilies, since the death of his father on 5 October 2015. The other claimant is Prince Carlo, Duke of Castro. Pedro is claimant to the sovereignty of the Constantinian Order, grand master of the Order of Saint Januarius, president of the Council of the four Spanish Military Orders of Santiago, Calatrava, Alcántara and Montesa, and grand commander of the Order of Alcántara. He is also a grandee as the son of an infante of Spain. Act of Cannes (1900). On 14 December 1900, Prince Carlos, next oldest brother to the  childless Prince Ferdinand, head of the House of Bourbon-Two Sicilies and irrefutable claimant to the extinct throne of the Two Sicilies, signed a private agreement of renunciation to the disappeared throne as he was marrying María de las Mercedes, Princess of Asturias, heir presumptive to the throne of Spain. This document, known as the Act of Cannes, was signed in abeyance to the 1759 Pragmatic Sanction signed by Charles III of Spain where it was established that the thrones of Spain and Naples should never be held by the same monarch and thus divided them for the sake of  a European balance of power. The newly independent Kingdom of Naples was ceded by Charles of Spain to his third child, who would become Ferdinand I of Naples. This would establish the kings of Naples and Sicily as cadet members of the Spanish royal family, and so the country enjoyed strong relationships with its 'mother state', following many of its legal customs. The Act of Cannes states: Supporters of the other claimant to the headship of the House of Bourbon-Two Sicilies, sometimes referred to as the Castrist faction, argue that because Prince Carlos signed this agreement, he relinquished all  of his rights and those of his descendants to both the headship of the family and the Sacred Military Constantinian Order of Saint George, and so the rights currently fall on Prince Carlo, Duke of Castro. However, supporters of Pedro, also known as the legitimists, argue that the Act of Cannes was drafted upon conditions that never arose, i.e. it would have only been valid if Prince Carlos would have indeed faced the situation of his wife inheriting the throne of Spain, something that never happened and was furthermore highly unlikely at the time the document was created. The legitimist  supporters also point out several flaws in the document and its interpretation. Also, they argue that the Act of Cannes never mentioned the headship of the House of Bourbon-Two Sicilies or the grand magistry of the Constantinian Order, and so this was therefore never renounced. Regardless, it was founded as trustee Farnesian dynastic order, and so it is the mainstream academic view that succession is not linked to the throne of Naples and Sicily. Following this logic, at the very least, the headship and grand magistry of the Constantinian Order would fall on Prince Pedro. Career. He has worked  as a structural engineer. He manages the family estate, "La Toledana", in Ciudad Real, Spain, as well as other landed estates in Spain. Marriage and issue. Pedro married Sofía Landaluce y Melgarejo (born 23 November 1973 in Madrid), daughter of José Manuel Landaluce y Domínguez and his wife María de las Nieves Blanca Melgarejo y González (granddaughter of the Dukes of San Fernando de Quiroga), on 30 March 2001 at Real Club de la Puerta de Hierro in Madrid. Pedro and Sofía have seven children:
