Juan Carlos I (baptized as Juan Carlos Alfonso Víctor María de Borbón y Borbón-Dos Sicilias; born January 5, 1938, Rome, Italy) is the reigning King of Spain.
On 22 November 1975, two days after the death of Francisco Franco, Juan Carlos was designated King according to the law of succession promulgated by Franco. He successfully oversaw the transition of Spain from dictatorship to parliamentary democracy. Polls from 2000 show that he is widely approved of by Spaniards. Juan Carlos's titles include that of King of Jerusalem, as successor to the royal family of Naples. He is also a descendant of Queen Victoria of the United Kingdom through his grandmother, Victoria Eugenie; of Louis XIV of France through the House of Bourbon; of the Emperor Charles V, who belonged to the Habsburg dynasty of the Holy Roman Empire; of the House of Savoy of Italy; etc.
His name, while rarely anglicised, is rendered as John Charles Alphonse Victor María of Bourbon (and Bourbon-Two Sicilies). He was given these names after his father (Juan de Borbón), grandfather (Alfonso XIII) and maternal grandfather (Prince Carlos de Borbón-Dos Sicilias).
