William the Conqueror William I (c. 1028 – 9 September 1087), usually known as William the Conqueror and sometimes William the Bastard, was the first Norman King of England, reigning from 1066 until his death in 1087. A descendant of Rollo, he was Duke of Normandy (as Duke William II) from 1035 onward. After a long struggle to establish his power, by 1060 his hold on Normandy was secure, and he launched the Norman conquest of England six years later. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands and by difficulties with his eldest son.
Adelaide of Maurienne Adelaide of Savoy (or Adelaide of Maurienne) (Italian: "Adelaide di Savoia" or "Adelasia di Moriana", French: "Adélaïde" or "Adèle de Maurienne") (1092 – 18 November 1154) was the second spouse but first Queen consort of Louis VI of France. Adelaide was the daughter of Humbert II of Savoy and Gisela of Burgundy, and niece of Pope Callixtus II, who once visited her court in France.
