Enrique de Borbón y Castellví, 2nd Duke of Seville

Enrique de Borbón y Castellví, 2nd Duke of Seville (Spanish: Don Enrique Pio Maria Francisco de Paula Luis Antonio de Borbón y Castellví, Duque de Sevilla; 3 October 1848 – 12 July 1894), was a Spanish nobleman and military officer who became the second Duke of Seville. He was the eldest son of the controversial Infante Enrique of Spain, who was a grandson of Charles IV of Spain and younger brother of Francis, Duke of Cádiz, king consort of Isabella II of Spain. Despite his family ties, Enrique was never entitled Infante of Spain due to the unequal marriage of his parents, which did not receive approval from Queen Isabella II.
