Biography[]
Infante Alfonso Carlos, Duke of San Jaime was born in London, United Kingdom on 12 September 1849, the son of Juan, Count of Montizon and Archduchess Maria Beatrix of Austria-Este. He and his brother (King Carlos VII of Spain) were raised in Modena by Duke Francis V of Modena due to his parents' separation, and he joined the Papal Zouaves in 1868. In September 1870, he defended the Porta Pia from the Royal Italian Army during its capture of Rome, and he escaped to Toulon in a French naval ship rather than give up his grandfather's sword. In 1872, he joined his brother's army during the Third Carlist War, becoming commander of the Royal Army of Catalonia. After the Carlists' defeat in 1876, he went into exile in Austria-Hungary, and he died in Vienna, Austria in 1936 at the age of 87.
