Q: Context_1 : 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. Context_2 : The Yaxley family was first founded in Suffolk where they held a family-seat as Lords of the Manor. After the Battle of Hastings in 1066, William, Duke of Normandy, having prevailed over King Harold, granted most of Britain to his many victorious Barons. It was not uncommon to find a Baron or a Bishop with 60 or more Lordships scattered throughout the country. These he gave to his sons, nephews and other junior lines of his family and they became known as under-tenants. They adopted the Norman system of surnames which identified the under-tenant with his holdings so as to distinguish him from the senior stem of the family. After many rebellious wars between his Barons, Duke William commissioned a census of all England to determine in 1086, settling once and for all, who held which lands. He called the census the Domesday Book, indicating that those holders registered would hold the land until the end of time. Hence, conjecturally, the surname is descended from the tenant of the lands of Yaxley, held by Hubert, a Norman noble from William Malet his over lord, who was recorded in the Domesday Book census of 1086. Context_3 : Canute IV (  1042  – 10 July 1086), later known as Canute the Holy (Danish: "Knud IV den Hellige" ) or Saint Canute ("Sankt Knud"), was King of Denmark from 1080 until 1086. Canute was an ambitious king who sought to strengthen the Danish monarchy, devotedly supported the Roman Catholic Church, and had designs on the English throne. Slain by rebels in 1086, he was the first Danish king to be canonized. He was recognized by the Roman Catholic Church as patron saint of Denmark in 1101. Context_4 : Akethorpe was an English village thought to have been located in what is now part of the Suffolk town of Lowestoft. The small village was described in the Domesday book as being home to 4 households in the Hundred of Lothingland. It formed part of the King's holding in 1086, having been held by Aelmer the Priest in 1066. Context_5 : La chambre du roi (] ), the King's Bedchamber, has always been the central feature of the king's apartment in traditional French palace design Ceremonies surrounding the daily life of the king — such as the "levée" (the ceremonial raising and dressing of the king held in the morning) and the "coucher" (the ceremonial undressing and putting to bed of the king) — were conducted in the bedchamber. Context_6 : Robert of Aumale (fl. 1086) (alias "d'Amarell, Damarell", etc., Latinised to "de Albemarle", "de Albamara", etc. ) was one of the Devon Domesday Book tenants-in-chief of King William the Conqueror (1066-1087). His lands, comprising 17 entries in the Domesday Book of 1086, later formed part of the very large Feudal barony of Plympton, whose later barons were the Courtenay family, Earls of Devon. Context_7 : Theobald FitzBerner (fl.1086), (Anglicised to Theobald son of Berner, Latinized to "Tetbaldus Filius Bernerius") was an Anglo-Norman warrior and magnate, one of the Devon Domesday Book tenants-in-chief of King William the Conqueror. The Domesday Book of 1086 lists him as the holder of 27 manors in Devon. Context_8 : Fujiwara no Morozane (Japanese language: 藤原 師実 ふじわらの もろざね) (1042 – March 14, 1101) was a regent of Japan and a chief of the Fujiwara clan during the late Heian period. He was known as Kyōgoku dono (Lord Kyōgoku) or Go-Uji dono (the Later Lord Uji, 後宇治殿). He held the positions of sessho or kanpaku for a twenty-year period, sessho from 1075 to 1086 during the reign of Emperor Shirakawa and from 1094 to 1099 during the reign of Emperor Horikawa, and kampaku from 1086 to 1094 during the reign of Emperor Horikawa. Context_9 : Gotshelm (floruit 1086) was an Anglo-Norman magnate and one of the 52 Devon Domesday Book tenants-in-chief of King William the Conqueror and was also a Cornwall Domesday Book tenant-in-chief. He is listed in the Domesday Book of 1086 as holding 28 estates or manors in Devon from the king. His brother was Walter de Claville (floruit 1086), also a Devon Domesday Book tenant-in-chief, who held 32 estates or manors in Devon from the king. Context_10 : Alfred the Breton (fl.1086) (Latinized to "Alvred Brito") was one of the Devon Domesday Book tenants-in-chief of King William the Conqueror. He had 22 landholdings in the county of Devonshire held in-chief according to the Domesday Book of 1086, and held further lands as a mesne tenant, including the manor of Panson in the parish of St Giles-in-the-Heath. His manors later descended to the feudal barony of Plympton. fact_1 :  It formed part of the King's holding in 1086, having been held by Aelmer the Priest in 1066. fact_2 : 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.
