Franco picked Juan Carlos to preserve his regime; the king dismantled it
Francisco Franco skipped a generation to choose his heir, passing over a father he considered too liberal in favour of a young prince he expected to mould. Juan Carlos swore loyalty to Franco's movement, then after taking the throne in 1975 steered Spain to its first free election since 1936.
Juan Carlos was born in Rome on 5 January 1938, where his grandfather Alfonso XIII, the last king before the 1931 republic, lived in exile. The cardinal who baptized him, Eugenio Pacelli, later became Pope Pius XII. His father, the Count of Barcelona, inherited the royal claim in 1941, but Franco, who had won the civil war and in 1947 declared Spain a monarchy with himself choosing the successor, distrusted him. His father persuaded Franco to let the boy be educated in Spain, and he arrived as a child, later passing through the army academy at Zaragoza, the naval and air force schools and the Complutense University of Madrid. His sister has said he struggled with dyslexia.
In 1954, on a Greek royal cruise attended by more than 100 European royals, he met Princess Sophia of Greece and Denmark, then 15. They married in Athens on 14 May 1962 and had three children, including the future Felipe VI. In 1969 Franco formally named him heir with the new title Prince of Spain, and parliament ratified the choice. A keen sailor, he competed in the Dragon class at the 1972 Olympics and finished 15th.
He began standing in for the ailing dictator in 1974 and became king when Franco died in November 1975. Instead of preserving the regime, he pushed reforms that produced the 1977 general election and a 1978 constitution, approved by referendum, restoring constitutional monarchy. In 1981 he played a major part in defeating a coup attempt launched in his name to bring back Francoism. By 2008 he was rated the most popular leader across Ibero-America.
Later years dimmed that reputation. Family controversies and an elephant-hunting trip during Spain's financial crisis drew anger, and in June 2014 he abdicated in favour of Felipe. Since August 2020 he has lived in self-imposed exile, over allegedly improper links to business deals in Saudi Arabia. He did not publicly describe the 1956 shooting accident that killed his younger brother Alfonso until his memoir appeared in 2025.
