Carmarthen Castle is noted as the place of death of Edmund Tudor, father of the first Tudor king of England, Henry VII. Edmund took possession of the castle during the Wars of the Roses on behalf of the House of Lancaster. Opposing Yorkist troops led by William Herbert captured the castle in August 1456, imprisoning Edmund Tudor, who died a prisoner there on 1 November. His 13-year old wife Margaret gave birth to Henry in January the following year.
