Alfonso, Prince of Asturias (10 May 1907 – 6 September 1938), was heir apparent to the throne of Spain from birth until he renounced his rights in 1933.
He was the eldest son of Alfonso XIII and his wife Victoria Eugenie of Battenberg.
Alfonso's renunciation of his rights as heir to the throne of Spain in order to marry Cuban commoner Edelmira Sampedro caused controversy at the time.
A similar situation would take place 3 years later in Britain with his cousin Edward VIII, who would abdicate as King of the United Kingdom to wed American divorcee Wallis Simpson.He died at the age of 31 as a result of a car accident.
Though appearing to have sustained minor injuries, his haemophilia, inherited by him from his great-grandmother Queen Victoria, led to fatal internal bleeding.
