Juan Carlos I of Spain

Juan Carlos I (Spanish: [xwaŋˈ kaɾlos]; Juan Carlos Alfonso Víctor María de Borbón y Borbón-Dos Sicilias; born 5 January 1938) is a member of the Spanish royal family who reigned as King of Spain from 1975 until his abdication in 2014. Although chosen by Francisco Franco as his successor, Juan Carlos helped dismantle the Francoist system and oversee the Spanish transition to democracy.

Juan Carlos is the son of Infante Juan, Count of Barcelona, and grandson of Alfonso XIII, the last king of Spain before the abolition of the monarchy in 1931 and the subsequent declaration of the Second Spanish Republic. Juan Carlos was born in Rome, Italy, during his family's exile. General Francisco Franco took over the government of Spain after his victory in the Spanish Civil War in 1939, yet in 1947 Spain's status as a monarchy was affirmed and a law was passed allowing Franco to choose his successor. Juan Carlos's father assumed his claims to the throne after former king Alfonso XIII died in February 1941. However, Franco saw Juan Carlos's father to be too liberal and in 1969 declared Juan Carlos to be Prince of Spain, his successor as head of state.

Juan Carlos spent his early years in Italy and came to Spain in 1947 to continue his studies. After completing his secondary education in 1955, he began his military training and entered the General Military Academy at Zaragoza. Later, he attended the Naval Military Academy and the General Academy of the Air, and finished his tertiary education at the University of Madrid. In 1962, Juan Carlos married Princess Sophia of Greece and Denmark in Athens. The couple have three children: Elena, Cristina, and Felipe. Due to Franco's advanced age and declining health amid his struggle with Parkinson's disease, Juan Carlos first began periodically acting as Spain's head of state in the summer of 1974. In November the following year, Franco died and Juan Carlos became king.
