Richard I of Normandy in the context of "Normans"

Gunnor or Gunnora (c. 950 – c. 1031) was Duchess of Normandy by marriage to Richard I of Normandy, having previously been his long-time mistress. She functioned as regent of Normandy during the absence of her spouse, as well as the adviser to him and later to his successor, their son Richard II.

Dudo, or Dudon, was a Picard historian, and dean of Saint-Quentin, where he was born in 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.

The Normans (Norman: Normaunds; French: Normands; Latin: Nortmanni/Normanni) were a population arising in the medieval Duchy of Normandy from the intermingling between Norse Viking settlers and locals of West Francia. The Norse settlements in West Francia followed a series of raids on the French northern coast mainly from what is now Denmark, although some also sailed from Norway and Sweden. These settlements were finally legitimized when Rollo, a Scandinavian Viking leader, agreed to swear fealty to King Charles III of West Francia following the siege of Chartres in 911, leading to the formation of the County of Rouen. This new fief, through kinship in the decades to come, would expand into what came to be known as the Duchy of Normandy. The Norse settlers, whom the region as well as its inhabitants were named after, adopted the language, religion, social customs and martial doctrine of the West Franks but their offspring nonetheless retained many of their traits, notably their mercenary tendencies and their fervour for adventures. The intermixing between Norse folk and native West Franks in Normandy produced an ethnic and cultural "Norman" identity in the first half of the 10th century, an identity which continued to evolve over the centuries.

The Norman dynasty had a major political, cultural and military impact on medieval Europe and the Near East. The Normans were historically famed for their martial spirit, and eventually for their Catholic piety as adherents of the Catholic orthodoxy of the Romance community. The original Norse settlers adopted the Gallo-Romance language of the Frankish land they settled, with their Old Norman dialect becoming known as Norman, Normaund or Norman French, an important literary language which is still spoken today in parts of mainland Normandy (Cotentinais and Cauchois dialects) and the nearby Channel Islands (Jèrriais and Guernésiais). The Duchy of Normandy, which arose from the Treaty of Saint-Clair-sur-Epte, was a great fief of medieval France. The Norman dukes exercised autonomous control of their holdings in Normandy, while at the same time being vassals owing fealty to the King of France, and under Richard I of Normandy (byname Richard sans Peur, meaning "Richard the Fearless"), the duchy was forged into a cohesive and formidable principality in feudal tenure.

Roger de Montgomery (died 1094), also known as Roger the Great, was the first Earl of Shrewsbury, and Earl of Arundel, in Sussex. His father was Roger de Montgomery, seigneur of Montgomery, a member of the House of Montgomery, and was probably a grandnephew of the Duchess Gunnor, wife of Duke Richard I of Normandy, the great-grandfather of William the Conqueror. The elder Roger had large landholdings in central Normandy, chiefly in the valley of the River Dives, which the younger Roger inherited.

William of Jumièges (born c. 1000 – died after 1070) (French: Guillaume de Jumièges) was a contemporary of the events of 1066, and one of the earliest writers on the subject of the Norman conquest of England. He is himself a shadowy figure, only known by his dedicatory letter to William the Conqueror as a monk of Jumièges. Since he also mentions that he was an eyewitness of some events from the reign of Duke Richard III (1026-7), it seems reasonable to assume that he was born some time about the year 1000. He probably entered the monastery during the first quarter of the eleventh century and received his education from Thierry de Mathonville. According to Orderic Vitalis, William's nickname was "Calculus". The meaning behind this nickname is unknown. His death, after 1070, is unrecorded. He was a Norman writing from a Norman point of view. Although only a monk with evidently no military training, he wrote with pride in the accomplishments of his people.

William of Jumièges was the original compiler of the history known as the Gesta Normannorum Ducum ("Deeds of the Dukes of the Normans"), written in about 1070. This was built upon the framework of an earlier history compiled by Dudo of Saint-Quentin, De moribus et actis primorum Normannorum ducum, between c. 996 and c. 1015. This work was commissioned by Duke Richard I, and "was renewed by his half-brother, Count Rodulf of Ivry, and his son Duke Richard II (996-1026)... Dudo's work was taken up by William of Jumièges in the 1050s, who revised, abbreviated and updated his De moribus and added an account of the reigns of Dukes Richard II, Richard III (1026-7), Robert I (1027-35), and William II [William the Conqueror]." He finished this by 1060 but added to it later when William the Conqueror had become king of England, bringing events up to 1070. The Gesta Normannorum Ducum was later expanded by the 12th-century monkish chroniclers Orderic Vitalis and Robert of Torigni.
