full_context: Document 1: Cuthbert of Canterbury: Cuthbert (died 26 October 760) was a medieval Anglo-Saxon Archbishop of Canterbury in England. Prior to his elevation to Canterbury, he was abbot of a monastic house, and perhaps may have been Bishop of Hereford also, but evidence for his holding Hereford mainly dates from after the Norman Conquest of England in 1066. While Archbishop, he held church councils and built a new church in Canterbury. It was during Cuthbert's archbishopric that the Diocese of York was raised to an archbishopric. Cuthbert died in 760 and was later regarded as a saint.
Document 2: Edward the Exile: Edward the Exile (1016 – 19 April 1057), also called "Edward Ætheling", was the son of King Edmund Ironside and of Ealdgyth. He spent most of his life in exile in the Kingdom of Hungary following the defeat of his father by Canute the Great.
Document 3: Oda of Canterbury: Oda (or Odo; died 958), called the Good or the Severe, was a 10th-century Archbishop of Canterbury in England. The son of a Danish invader, Oda became Bishop of Ramsbury before 928. A number of stories were told about his actions both prior to becoming and while a bishop, but few of these incidents are recorded in contemporary accounts. After being named to Canterbury in 941, Oda was instrumental in crafting royal legislation as well as involved in providing rules for his clergy. Oda was also involved in the efforts to reform religious life in England. He died in 958 and legendary tales afterwards were ascribed to him. Later he came to be regarded as a saint, and a hagiography was written in the late 11th or early 12th century.
Document 4: Archdeacon George of the Cross: Archdeacon George (Geevarghese) of the cross was the son of the elder brother of Archdeacon Geevarghese of Christ. By the last year of Bishop Mar Abraham, he became the Archdeacon. After the death of Persian Bishop Mar Abraham in 1597, he led the Indian Church. He led the church amidst Portuguese intervention. The synod of Diamper 1599 was held during his time. In 1601 Francis Roz became Bishop appointed by Menezis of Goa. In the beginning there was cordiality. But the deliberate downgradation of Angamaly and the inertia of Bishop Roz frustrated him. When the Archdeacon protested, Roz ex-communicated him. In 1615 Bishop and Archdeacon reconciled each other, but again fell out later. The next Bishop Britto also did not recognize the Archdeacon's ecclesiastical status. He led the church in a period of severe stress turmoil. He led the church in a period of severe stress and held it together. After his time and his brother's time the root family of Pakalomattam became heirless. The only son shifted residence to Alappatt house. He is believed to have been buried in the forefront of Pakalomattam Thravadu (Kuravilangadu).
Document 5: Becket Casket: The Becket Casket is a reliquary in Limoges enamel now in the Victoria and Albert Museum. It is made of gilt-copper round a wooden core, decorated with champlevé enamel, and of a shape called a "chasse". It was made in about 1180–90 in Limoges, France, and depicts one of the most infamous events in English history. On the night of 29 December 1170, Archbishop Thomas Becket was murdered in Canterbury cathedral by four knights obeying the wishes of King Henry II. It provoked outrage throughout Europe, and pilgrims flocked to Canterbury to pray at the site of the murder. In 1173 Becket was canonized and his shrine was one of the most famous in the Christian world, until its total destruction in 1538 during the reign of Henry VIII. It is thought that this particular casket was made to hold the relics of Thomas Becket that were taken to Peterborough Abbey (now Peterborough Cathedral) by Abbot Benedict in 1177. Benedict had been Prior at Canterbury Cathedral and therefore saw Becket's assassination.
Document 6: Edmund Ætheling: Edmund Ætheling ( ;  1015–17 – possibly 1046, certainly by 1054) was a member of the royal House of Wessex as the son of Edmund Ironside, who briefly ruled as King of England between April and November 1016. He fought the Danish Vikings under Cnut the Great, but following the Danish victory at the Battle of Assandun in October, it was agreed that Ironside would rule Wessex, while Cnut took Mercia and probably Northumbria. In November 1016, Ironside died and Cnut became King of all England.
Document 7: Simeon (abbot): Simeon (died 21 November 1093) was a relative of King William I of England and the brother of Walkelin, Bishop of Winchester. It was through his brother's influence that Simeon was made prior of Winchester, then in 1082 Abbot of Ely, where he began work on the present Ely Cathedral. He recovered for the monastery of Ely the lands which had been allotted to the Normans during their siege of the island of Ely when it was held by Hereward the Wake.
Document 8: Edmund Ironside: Edmund II (died 30 November 1016), usually known as Edmund Ironside, was King of England from 23 April to 30 November 1016. He was the son of King Æthelred the Unready and his first wife, Ælfgifu of York. Edmund's reign was marred by a war he had inherited from his father, his cognomen "Ironside" was given to him "because of his valour" in resisting the Danish invasion led by Cnut the Great.
Document 9: Azor (landowner): Azor was one of the most powerful English landowners at the time of Edward the Confessor in the 11th century. He was a kinsman and chamberlain of Brihtheah, a bishop of Worcester and a former abbot of Pershore. He owned property from Lincolnshire down to the Isle of Wight in many counties and like another great landowner of the times, Toki, he also owned urban property in addition to his vast possession of lavish country estates. He is mentioned in the Domesday Book and appears in countless histories of English counties along with his sons,
Document 10: Edward the Confessor: Edward the Confessor (Old English: "Ēadƿeard Andettere" ] , Latin: "Eduardus Confessor" ] ; c. 1003 – 5 January 1066), also known as Saint Edward the Confessor, was among the last Anglo-Saxon kings of England. Usually considered the last king of the House of Wessex, he ruled from 1042 to 1066.
Document 11: Henry of Lund: Henry was an 11th-century bishop and Christian missionary. He was probably the keeper of the treasury of King Canute the Great in England. Sometime before the year 1035, according to Adam of Bremen, Henry went to Orkney as bishop. As Bishop of Orkney, he was probably more of a missionary bishop, and may have been under the metropolitan authority of the Archbishop of York. He is possibly the Henry who went to Iceland for two undatable years. In 1060/1, the King of Denmark, Sweyn II, appointed him Bishop of Lund. He is the first man known to have held the bishopric of Lund, as well as Orkney. He is said to have died from an alcoholic episode sometime in the mid-1060s.
Document 12: Edgar Ætheling: Edgar Ætheling (also spelt Æþeling, Aetheling, Atheling or Etheling) or Edgar II (c. 1051 – c. 1126) was the last male member of the royal house of Cerdic of Wessex (see House of Wessex family tree). He was proclaimed, but never crowned, King of England in 1066.
Document 13: Spearhafoc: Spearhafoc was an eleventh-century Anglo-Saxon artist and Benedictine monk, whose artistic talent was apparently the cause of his rapid elevation to Abbot of Abingdon in 1047–48 and Bishop-Elect of London in 1051. After his consecration as bishop was thwarted, he vanished with the gold and jewels he had been given to make into a crown for King Edward the Confessor, and was never seen again. He was also famous for a miracle, on which his end perhaps casts a different light.
Document 14: Æthelred the Unready: Æthelred II, also dubbed the Unready (Old English: Æþelræd, ] ), (  966 – 23 April 1016) was King of the English (978–1013 and 1014–1016). He was the son of King Edgar the Peaceful and Queen Ælfthryth and was around 12 years old when his half-brother Edward the Martyr was murdered on 18 March 978. Although Æthelred was not personally suspected of participation, the murder was committed at Corfe Castle by his attendants, making it more difficult for the new king to rally the nation against the military raids by Danes, especially as the legend of St Edward the Martyr grew.
Document 15: Ancestry of the Godwins: Very little is known for certain of the ancestry of the Godwins, the family of the last Anglo-Saxon King of England, Harold II. When King Edward the Confessor died in January 1066 his closest relative was his great-nephew, Edgar the Ætheling, but he was young and lacked powerful supporters. Harold was the head of the most powerful family in England and Edward's brother-in-law, and he became king. In September 1066 Harold defeated and killed King Harald Hardrada of Norway at the Battle of Stamford Bridge, and Harold was himself defeated and killed the following month by William the Conqueror at the Battle of Hastings.
