The Liber Pontificalis is a book of biographies of popes from Saint Peter until the 15th century. The original publication of the Liber Pontificalis stopped with Pope Adrian II (867–872) or Pope Stephen V (885–891), but it was later supplemented in a different style until Pope Eugene IV (1431–1447) and then Pope Pius II (1458–1464). Although quoted virtually uncritically from the 8th to 18th centuries, the Liber Pontificalis has undergone intense modern scholarly scrutiny. The work of the French priest Louis Duchesne, and of others has highlighted some of the underlying redactional motivations of different sections, though such interests are so disparate and varied as to render improbable one popularizer's claim that it is an "unofficial instrument of pontifical propaganda."
Eustace IV ruled the County of Boulogne from 1146 until his death. He was the eldest son of King Stephen of England and Countess Matilda I of Boulogne. When his father seized the English throne on Henry I's death in 1135, he became heir apparent to the English throne but predeceased his father.
William of Malmesbury was the foremost English historian of the 12th century. He has been ranked among the most talented English historians since Bede. Modern historian C. Warren Hollister described him as "a gifted historical scholar and an omnivorous reader, impressively well versed in the literature of classical, patristic, and earlier medieval times as well as in the writings of his own contemporaries. Indeed William may well have been the most learned man in twelfth-century Western Europe."
Benedict, sometimes known as Benedictus Abbas, was abbot of Peterborough. His name was formerly erroneously associated with the Gesta Henrici Regis Secundi and Gesta Regis Ricardi, English 12th-century chronicles, which are now attributed to Roger of Howden.
William of Poitiers was a Norman priest who served as the chaplain of Duke William II of Normandy, for whom he chronicled the Norman conquest of England in his Gesta Willelmi ducis Normannorum et regis Anglorum. He had trained as a soldier before taking holy orders.
Roger of Howden or Hoveden was a 12th-century English chronicler, diplomat and head of the minster of Howden in the East Riding of Yorkshire.
Dudo, or Dudon, was a Picard historian, and dean of Saint-Quentin, where he was born the 960s. He was an erudite scholar and he likely acquired his education in Liège or perhaps Laon. By 987, Dudo had become a canon at St Quentin, the abbacy of which was held by the counts of Vermandois. In that year he was sent on a diplomatic mission to Richard I of Normandy by Albert I, Count of Vermandois which was successful. Dudo became a frequent visitor to the Norman court in the two years prior to Richard's death in 996. In a letter to Adalbero, Bishop of Laon, Dudo said that, as a result, Richard asked him to write a work recording "the customs and deeds of the Norman Land, the rights established within the kingdom of his great-grandfather Rollo". During a second stay in Normandy, Dudo wrote his history of the Normans, a task which Duke Richard had urged him to undertake. Very little else is known about his life, except that he died before 1043.
Richard of Hexham was an English chronicler. He became prior of Hexham about 1141, and died between 1155 and 1167.
Robert of Torigni was a Norman monk, prior, abbot and twelfth-century chronicler.
Alexander of Lincoln was a medieval English Bishop of Lincoln, a member of an important administrative and ecclesiastical family. He was the nephew of Roger of Salisbury, a Bishop of Salisbury and Chancellor of England under King Henry I, and he was also related to Nigel, Bishop of Ely. Educated at Laon, Alexander served in his uncle's diocese as an archdeacon in the early 1120s. Unlike his relatives, he held no office in the government before his appointment as Bishop of Lincoln in 1123. Alexander became a frequent visitor to King Henry's court after his appointment to the episcopate, often witnessing royal documents, and he served as a royal justice in Lincolnshire.
The Gesta Regum Anglorum, originally titled De Gestis Regum Anglorum and also anglicized as The Chronicles or The History of the Kings of England, is an early-12th-century history of the kings of England by William of Malmesbury. It is a companion work of his Gesta Pontificum Anglorum and was followed by his Historia Novella, which continued its account for several more years. The portions of the work concerning the First Crusade were derived from Gesta Francorum Iherusalem peregrinantium, a chronicle by Fulcher of Chartres.
Nigel was an Anglo-Norman clergyman and administrator who served as Bishop of Ely from 1133 to 1169. He came from an ecclesiastical family; his uncle Roger of Salisbury was a bishop and government minister for King Henry I, and other relatives also held offices in the English Church and government. Nigel owed his advancement to his uncle, as did Nigel's probable brother Alexander, who like Nigel was advanced to episcopal status. Nigel was educated on the continent before becoming a royal administrator. He served as Treasurer of England under King Henry, before being appointed to the see, or bishopric, of Ely in 1133. His tenure was marked by conflicts with the monks of his cathedral chapter, who believed that Nigel kept income for himself that should properly have gone to them.
William Warelwast was a medieval Norman cleric and Bishop of Exeter in England. Warelwast was a native of Normandy, but little is known about his background before 1087, when he appears as a royal clerk for King William II. Most of his royal service to William was as a diplomatic envoy, as he was heavily involved in the king's dispute with Anselm, the Archbishop of Canterbury, which constituted the English theatre of the Investiture Controversy. He went several times to Rome as an emissary to the papacy on business related to Anselm, one of whose supporters, the medieval chronicler Eadmer, alleged that Warelwast bribed the pope and the papal officials to secure favourable outcomes for King William.
Robert or sometimes Robert of Lewes was a medieval English Bishop of Bath. He began his career as a monk at Lewes Priory as well as performing administrative functions for Henry of Blois. It was Henry who secured Robert's selection as bishop. While bishop, Robert built in his diocese and set up the system of archdeacons there. He may have been the author of the Gesta Stephani, a work detailing the history of King Stephen's life.
The Recueil des historiens des croisades is a major collection of several thousand medieval documents written during the Crusades. The documents were collected and published in Paris in the 19th century, and include documents in Latin, Greek, Arabic, Old French, and Armenian. The documents cover the entire period of the Crusades, and are frequently cited in scholarly works, as a way of locating a specific document. When being quoted in citations, the collection is often abbreviated as RHC or R.H.C..
The Liber Eliensis is a 12th-century English chronicle and history, written in Latin. Composed in three books, it was written at Ely Abbey on the island of Ely in the fenlands of eastern Cambridgeshire. Ely Abbey became the cathedral of a newly formed bishopric in 1109. Traditionally the author of the anonymous work has been given as Richard or Thomas, two monks at Ely, one of whom, Richard, has been identified with an official of the monastery, but some historians hold that neither Richard nor Thomas was the author.
The Gesta Pontificum Anglorum, originally known as De Gestis Pontificum Anglorum and sometimes anglicized as The History or The Chronicle of the English Bishops, is an ecclesiastical history of England written by William of Malmesbury in the early 12th century. It covers the period from the arrival of St Augustine in AD 597 until the time it was written. Work on it was begun before Matilda's death in 1118 and the first version of the work was completed in about 1125. William drew upon extensive research, first-hand experience and a number of sources to produce the work. It is unusual for a medieval work of history, even compared to William's other works, in that its contents are so logically structured. The History of the English Bishops is one of the most important sources regarding the ecclesiastical history of England for the period after the death of Bede.
Brian fitz Count was descended from the Breton ducal house, and became an Anglo-Norman noble, holding the lordships of Wallingford and Abergavenny. He was a loyal adherent of Henry I, King of England, and a staunch supporter of his daughter, the Empress Matilda, during the Anarchy (1135–1153).
The siege of Oxford took place during the Anarchy—a period of civil war following the death of Henry I of England without a male heir—in 1142. Fought between his nephew, Stephen of Blois, and his daughter, the Empress Matilda, who had recently been expelled from her base in Westminster and chosen the City of Oxford as her new headquarters. Oxford by now was effectively a regional capital and important in its own right. It was a well-defended city with both rivers and walls protecting it, and was also strategically important as it was at a crossroads between the north, south-east and west of England, and also not far from London.
