Who is Queen Sofia of Spain?
Queen Sofía of Spain (born 2 November 1938) is a member of the Spanish royal family, who was Queen of Spain from 1975 to 2014 as the wife of King Juan Carlos I.
Born Princess Sophia of Greece and Denmark (Greek: Σοφία), she is the first child of King Paul of Greece and Frederica of Hanover.
As her family was forced into exile during the Second World War, she spent part of her childhood in Egypt, returning to Greece in 1946.
She completed her secondary education in a boarding school in Germany before returning to Greece where she specialised in childcare, music and archaeology.
Sofía was in Greece on a private visit to her brother, King Constantine II, when the 1967 Greek military coup took place. Since then, he has been stripped of his title, citizenship and property in Greece.
Except for a brief stay for the funeral of her mother in 1981, Queen Sofía did not visit the Hellenic Republic until 1998.
Queen Sofía and former King Juan Carlos have three children: Elena (born 20 December 1963); Cristina (born 13 June 1965); and Felipe (born 30 January 1968).
