Infante Carlos, Duke of Madrid, was a Spanish nobleman born on March 30, 1938. He is a member of the House of Bourbon and a claimant to the Spanish throne as the head of the Carlist movement, which advocates for a traditionalist monarchy in Spain. His claim is based on his descent from Carlos María Isidro de Borbón, the founder of the Carlist cause. Carlos was raised in a royal environment and spent much of his life in exile due to political circumstances in Spain. He has been involved in various cultural and charitable activities, promoting Spanish heritage and Carlist ideals throughout his life.
