Queen Fabiola of Belgium (died 2014)

Fabiola Fernanda María-de-las-Victorias Antonia Adelaida de Mora y Aragón was Queen of the Belgians as the wife of King Baudouin from their marriage in 1960 until his death in 1993. The couple had no children, as all five of Fabiola's pregnancies resulted in miscarriage, so the Crown passed to her husband's younger brother, King Albert II.
