Infante Jaime, Duke of Segovia

Because he was deaf, as the result of a childhood operation, he renounced his rights to the Spanish throne for himself and his descendants on 21 June/23 June 1933. He was then granted the title "Duke of Segovia" by King Alfonso XIII. After his father's death in 1941, he proclaimed himself the senior legitimate male heir of the House of Capet, heir to the French throne, and head of the House of Bourbon. He then took the title of "Duke of Anjou" and became, in the opinion of French legitimists, the de jure king of France as "Henri VI", though to a minority as "Jacques II" (after 1957, he signed all documents as Jacques Henri).

In 1921, he became the 1,153rd Knight of the Order of the Golden Fleece and Knight with Collar of the Order of Charles III and Grand Cross of the Order of Isabella the Catholic both in 1925 (Collar of the Order of Isabella the Catholic in 1931).

On 4 March 1935, in Rome, Jaime married Victoire Jeanne Emmanuelle (Emanuela) Joséphine Pierre Marie de Dampierre (8 November 1913 in Rome – 3 May 2012 in Rome), daughter of Roger de Dampierre, 2nd Duque de San Lorenzo Nuovo, Vicomte de Dampierre (1892–1975) and of Donna Vittoria Ruspoli (1892–1982), daughter of Emanuele Ruspoli, 1st Principe di Poggio Suasa and his third wife English American Josephine Mary Curtis. Don Jaime and Donna Emanuela had two sons, named after Jaime's hemophiliac brothers, Alfonso and Gonzalo:

• Alfonso, Duke of Anjou and Cádiz (20 April 1936 – 20 January 1989) he married María del Carmen Martínez-Bordiú y Franco on 8 March 1972 and they were divorced in 1986. They had two sons and three grandchildren.
• Gonzalo, Duke of Aquitaine (5 June 1937 – 5 March 2000) he married, Carmen Harto on 18 April 1983. He remarried Maria de las Mercedes Licer on 25 June 1984 and they were divorced on 31 January 1989. He remarried again Emanuela Protalongo on 30 June 1984 and they were separated on 7 March 1986. Gonzalo and Emanuela were also married in a religious ceremony on 17 September 1992. He has an illegitimate daughter and five grandsons.

Don Jaime and Emmanuelle de Dampierre divorced on 6 May 1947 in Bucharest (recognized by the Italian courts on 3 June 1949 in Turin but never recognized in Spain) and, on 3 August 1949 in Innsbruck, Don Jaime remarried civilly to divorced singer Charlotte Luise Auguste Tiedemann (2 January 1919 in Königsberg – 3 July 1979 in Berlin), daughter of Otto Eugen Tiedemann and wife Luise Klein. In the eyes of the Roman Catholic Church and of the French legitimists, Emmanuelle de Dampierre remained always his wife. The second marriage produced no children. His first wife remarried in Vienna, on 21 November 1949, to Antonio Sozzani (12 July 1918 in Milan – 6 January 2007 in Milan), son of Cesare Sozzani and wife Cristina Alemani, without issue.

On 6 December 1949, Don Jaime retracted his renunciation of the throne of Spain. On 3 May 1964, he took the title "Duke of Madrid" as head of a Carlist branch of the Spanish succession (recognized as King Jaime IV of Spain by the legitimist group of Carlists who did not support the Bourbon-Parma claim after Alfonso Carlos, Duke of San Jaime died in 1936). On 19 July 1969, Don Jaime definitively renounced the Spanish succession in favour of his nephew, the future King Juan Carlos I of Spain, at the request of his elder son, Alfonso de Borbón.

Don Jaime died in St. Gall Cantonal Hospital in Switzerland on 20 March 1975. He is buried at the Royal Monastery of San Lorenzo de El Escorial.
