Juan Carlos I of Spain

Juan Carlos I rarely anglicised as John Charles I; Juan Carlos Alfonso Víctor María de Borbón y Borbón-Dos Sicilias; born 5 January 1938, is the current King of Spain.
Spanish dictator Francisco Franco named Juan Carlos as the next head of state in 1969. He became King on 22 November 1975, two days after Franco's death, the first reigning monarch since 1931. Soon after being crowned, Juan Carlos introduced reforms to dismantle the Francoist regime and begin the Spanish transition to democracy. This led to the approval of the Spanish Constitution of 1978 in a referendum, which established a constitutional monarchy. Juan Carlos also played a major role in stopping the 1981 coup attempt.
According to the Spanish Constitution, the monarch is the head-of-state and commander-in-chief of the Spanish Armed Forces and also plays a role in promoting Ibero-American relations, the "nations of its historical community". In this capacity, the King of Spain serves as the president of the Ibero-American States Organization, representing over 700,000,000 people in 24 member nations worldwide. In 2008 he was considered the most popular leader in all Ibero-America.
