Juan, Count of Montizón
Don Juan Carlos María Isidro de Borbón, Count of Montizón was the Carlist claimant to the throne of Spain from 1860 to 1868, and the Legitimist claimant to the throne of France from 1883 to 1887, and a possible pretender to Mexican throne before the establishment of the Second Mexican Empire in the 1860s.
Youth and marriage
Juan was born at the Palacio Real de Aranjuez in the province of Madrid, the younger son of the Infante Carlos of Spain, brother of King Ferdinand VII, and his first wife, Infanta Maria Francisca of Portugal. He was raised in an atmosphere imbued with traditional values of loyalty to the monarchy and the Church.In March 1833 Juan moved with his family to Portugal. The following September Juan's uncle Ferdinand VII died, and Juan's father Carlos claimed the throne of Spain as King Carlos V. Carlos opposed the succession of his infant niece Queen Isabella II whose mother the Queen Regent Maria Christina managed to take control on behalf of her daughter. In June 1834 Juan moved with his family to England, where they lived at Gloucester Lodge, Old Brompton Road, and later at Alverstoke Old Rectory, Hampshire. He remained in England throughout the First Carlist War, playing no part in it on account of his youth.
On 15 January 1837 the Cortes which was controlled by the Isabellists passed a law, ratified by the Queen Regent Maria Christina, which excluded Juan, his father, and brothers from the Spanish succession. By the same law the title of Infante of Spain was removed from Juan and his family. From the perspective of the Carlists this law was invalid.
On 6 February 1847, Juan married the Archduchess Maria Beatrix of Austria-Este, daughter of Duke Francis IV of Modena and Princess Maria Beatrice of Savoy. The couple had two sons:
Juan and Beatrix lived first in Modena, but had to leave during the revolution of 1848. After a brief time in Austria, they settled in London where their younger son was born. In spite of the conservatism and religious piety of his own family and particularly that of his wife, Juan developed liberal tendencies. He separated from his wife who returned to Modena where she raised her two sons. Juan was an active photographer and a founder member of the Photographic Society from 1853 and is last recorded as a member in 1866.
Claimant to the throne of Spain
Juan played no part in the 1860 Carlist rising led by his brother Carlos Luis, count of Montemolín. On 21 April Carlos Luis was captured by the troops of Isabella II and forced to renounce his claims to the Spanish throne. On 2 June Juan published a declaration affirming his accession as Juan III, King of Spain; henceforward he used the title conde de Montizón. Juan's accession declaration used phrases such as "the light and progress of the age"; these phrases caused great offence to many Carlists most of whom refused to support him.Once he had left Spain, his brother Carlos Luis renounced his abdication. On 15 June he declared that it was invalid since he had been forced to sign against his will. Juan refused to accept his brother's declaration. Until the unexpected death of Carlos Luis the following January, there were two Carlist claimants.
During the early 1860s the popularity of the government of Isabella II continued to decline. Juan's liberal views, however, ensured that he was not a viable candidate for the Carlists. In 1866, Juan's elder son Carlos asked his father to renounce his rights, but he did nothing. Two years later, however, on 3 October 1868, Juan signed a decree of abdication at Paris. He became an active supporter of his son Carlos' attempts to regain the Spanish throne in the Third Carlist War.
Claimant to the throne of France
On 24 August 1883 Juan's distant cousin and brother-in-law Henri, comte de Chambord died. Henri had been the Legitimist claimant to the throne of France. Henri's widow, Archduchess Maria Theresa of Austria-Este, and a minority of his supporters held that Juan as senior male descendant of Louis XIV was his successor. They proclaimed him as Jean III, King of France and Navarre. He issued a declaration saying, "Having become Head of the House of Bourbon by the death of my brother-in-law and cousin, the Comte de Chambord, I declare that I do not in any way renounce the rights to the throne of France which I have held since my birth". But other than this declaration he made no active claim to the French throne.Claimant to the throne of Mexico
In 1821, when the Mexican Empire first achieved its independence, its original plan was for it to be ruled by a personal union with Ferdinand VII. Despite him declining the throne, many Mexican conservatives did not give up on their hope to have a Bourbon rule as Emperor of Mexico.During the Convention of London the issue was brought up that Juan, Count of Montizon could be a possible pretender to the Mexican throne. But it is noted that when offered the crown, he had declined it, thus the Mexican conservatives choose instead Archduke Ferdinand Maxilimilian to take the throne, who accepted it.
Had he accepted the crown, his title would've been Juan I, Emperor of Mexico.
Death
Juan died of angina at his home in Hove on Friday 18 November 1887. His death was registered by an Ellen Sarah Carter. His body was moved to the Church of the Sacred Heart, Norton Road, Hove on 20 November, where he lay in state until his funeral mass was held on 24 November in the presence of his two legitimate sons; Don Carlos, Duke of Madrid and Don Alfonso, Duke of San Jaime.His body was moved on 6 January 1888 from Hove to St Katherine's Dock London along with the body of his Mother, Queen Maria Francisa, who had been buried at the Roman Catholic Church of our Lady, Gosport, where she had been laid to rest in September 1834. The bodies left aboard the General Steamship Navigation Company's vessel on 7 January bound for Hamburg and then via Berlin and Vienna and on to Trieste where it is buried in the chapel of Saint Charles Borromeo in Trieste Cathedral. The inscription on his tomb names him as the King of Spain.
