Juan Carlos I sibling Infanta Pilar, Duchess of Badajoz
Early life (1938–1969)
Juan Carlos Alfonso Víctor María was born to Infante Juan, Count of Barcelona, and Princess María de las Mercedes of Bourbon-Two Sicilies in their family home in Rome, where his grandfather King Alfonso XIII of Spain and other members of the Spanish royal family lived in exile following the proclamation of the Second Spanish Republic in 1931. He was baptized as Juan Carlos Alfonso Víctor María de Borbón y Borbón-Dos Sicilias by Cardinal Eugenio Pacelli, the future Pope Pius XII.
His early life was dictated largely by the political concerns of his father and General Franco. He moved to Spain in 1948 to be educated there after his father persuaded Franco to allow it. He began his studies in San Sebastián and finished them in 1954 at the Instituto San Isidro in Madrid. He then joined the army, doing his officer training from 1955 to 1957 at the Military Academy of Zaragoza.
According to his sister Pilar, he had difficulty in his studies because of dyslexia.He has two sisters: Infanta Pilar, Duchess of Badajoz (1936–2020); and Infanta Margarita, Duchess of Soria (born 1939). He also had a younger brother, Alfonso.
The rendering of his name as "Juan Carlos" (the first and second particles of his baptismal name) was a modification by choice of Francisco Franco. He was always known in his familiar circle simply as "Juan" or "Juanito".Brother's death
On the evening of Holy Thursday, 29 March 1956, Juan Carlos's younger brother Alfonso died in a gun accident at the family's home Villa Giralda in Estoril, on the Portuguese Riviera. The Spanish Embassy in Portugal then issued the following official communiqué:
Whilst His Highness Prince Alfonso was cleaning a revolver last evening with his brother, a shot was fired hitting his forehead and killing him in a few minutes. The accident took place at 20.30 hours, after the Infante's return from the Maundy Thursday religious service, during which he had received holy communion.
Alfonso had won a local junior golf tournament earlier in the day, then went to evening Mass and rushed up to the room to see Juan Carlos who had come home for the Easter holidays from military school. Both Juan Carlos, age 18, and Alfonso, age 14, had been apparently playing with a .22 caliber Long Automatic Star revolver owned by Alfonso. As they were alone in the room, it is unclear how Alfonso was shot, but according to Josefina Carolo, dressmaker to Juan Carlos's mother, Juan Carlos pointed the pistol at Alfonso and pulled the trigger, unaware that it was loaded. Bernardo Arnoso, a Portuguese friend of Juan Carlos, also said that Juan Carlos had told him he had fired the pistol not knowing that it was loaded, and adding that the bullet ricocheted off a wall, hitting Alfonso in the face. Helena Matheopoulos, a Greek author who spoke with Juan Carlos's sister Pilar, said that Alfonso had been out of the room and when he returned and pushed the door open, the door knocked Juan Carlos in the arm, causing him to fire the pistol.
After learning this news, his father Juan of Bourbon reportedly grabbed Juan Carlos by the neck and shouted at him angrily, "Swear to me that you didn't do it on purpose!" Two days later, he sent him back to the military academy. Following a later declaration of María de las Mercedes, Paul Preston argues that the content of the former testimony implies that Juan Carlos had pointed the gun at Alfonso, apparently not knowing that the gun was loaded, and pulled the trigger.
