Alfonso, Prince of Asturias (1907–1938)

In 1938, Alfonso, then resident in the United States, publicly stated his readiness to accept the Spanish crown if called on to do so. Spain was at this date in the midst of civil war. This action reversed Alfonso's renunciation of 1933 and led to his being disavowed by his father King Alfonso.

A car crash led to Alfonso's early death in 1938, at the age of 31. He was being driven at night through Miami by an entertainer, Miss Mildred Gaydon, who swerved to avoid a truck. The car crashed into a telephone booth and Alfonso appeared to have only minor injuries but his haemophilia led to fatal internal bleeding. He was entombed at Woodlawn Park Cemetery and Mausoleum (now Caballero Rivero Woodlawn Park North Cemetery and Mausoleum) in Miami, and was re-entombed in 1985 at the Pantheon of the Princes in El Escorial. His first wife, who had been allowed to retain the title Countess of Covadonga, was asked by the royal family to attend the re-entombment, but she declined.

In a civil ceremony on 3 July 1937, Alfonso married another commoner, Marta Esther Rocafort-Altuzarra in Havana. They divorced on 8 January 1938. He had no children by either of his wives. However, Alfonso de Bourbon, a resident of California, later claimed to be an illegitimate son of Alfonso.

There had been plans for young Alfonso's deposition from succession, but ultimately he himself renounced his rights to the then-defunct throne to marry a commoner, Edelmira Sampedro y Robato, religiously in Ouchy on 21 June 1933, after which Alfonso took the courtesy title Count of Covadonga. This was required by the regulations for the succession set by the Pragmatic Sanction of Charles III. The couple divorced 8 May 1937, with Edelmira keeping the title Countess of Covadonga.

Alfonso's father faced increasing political problems that led Spain to become a republic in 1931 when the monarch was deposed. The family moved into exile.

Alfonso, Prince of Asturias (10 May 1907 – 6 September 1938), was heir apparent to the throne of Spain from birth until the abolition of the monarchy in 1931. He renounced his rights to the defunct throne in 1933. Alfonso was the eldest son of King Alfonso XIII of Spain and his wife Victoria Eugenie of Battenberg.

He was born on 10 May 1907 at the Royal Palace of Madrid. As decreed by custom, he was registered by the Marquis of Figueroa, Minister of Justice, in the Civil Registry of the Royal Family as Alfonso Pío Cristino Eduardo Francisco Guillermo Carlos Enrique Eugenio Fernando Antonio Venancio.

Alfonso was the 1,120th Knight of the Order of the Golden Fleece in Spain and Knight with Collar of the Order of Charles III, inducted as both shortly after his birth in 1907.
