Толедский собор
King Sancho IV of Castile died in the city of Toledo on 25 April 1295, leaving his eldest son Ferdinand as heir of the throne. After the burial of the sovereign at Toledo Cathedral, his widow María de Molina retired to the Alcázar of Toledo for a mourning of nine days. The now Dowager Queen was in charge of the regency of her 9-years-old son. Because the marriage between Sancho IV and María de Molina was without validity, all their children (including the now Ferdinand IV) were illegitimate, so the Dowager Queen had to face numerous problems to keep her son on the throne.
