Spanish royal pretender, as the Carlist claimant to the throne of Spain under the name Jaime III, and the Legitimist claimant to the throne of France as Jacques I, known in France as Jacques de Bourbon, Duke of Anjou.
Jaime was the only son of Carlos, Duke of Madrid, and of his wife Princess Margherita of Bourbon-Parma.
In 1896 Jaime received a commission in the Russian army, initially stationed in Odessa. As member of the Imperial Russian Army in 1900 and 1901 he took part in the Boxer Expedition, fighting in the Battle of Beitang. In 1904 and 1905 he took part in the Russo-Japanese War fighting in the Battle of Liaoyang and the Battle of Vafangon. At that time he was formally assigned to Warsaw, where he spent almost 6 years on a highly intermittent basis, until he departed for Austria in late 1903.
On 18 July 1909 Jaime succeeded his father as Carlist claimant to the throne of Spain and Legitimist claimant to the throne of France.
He died on 2 October 1931, aged 61, in Paris, France.
