(also known as Galicieulv (Galiciwolf) c. 1010), aka Jarl Galizur-Ulfric was a Danish jarl, a Viking chieftain who became famous for his raids, looting and pillaging the lands of Galicia in the early eleventh century, perhaps in 1028 or 1048, during the reign of Bermudo III and Ferdinand I of Leon.
 According to Saxo Grammaticus and the Knýtlinga saga, Galicieulv was grandfather of Boedil Thurgotsdatter, the wife of Eric I of Denmark.
Svein Knutsson (Old Norse: "Sveinn Knútsson") c. 1016–1035, was the son of Cnut the Great, king of Denmark, Norway, and England, and his first wife Ælfgifu of Northampton, a Mercian noblewoman.
 In 1017 Cnut married Emma of Normandy, but there is no evidence that Ælfgifu was repudiated, and in 1030 Cnut sent her and Svein as regents to rule Norway.
 However, their rule was considered oppressive by the Norwegians, and they were expelled in 1034.
 They imposed new taxes and harsh laws that made them unpopular.
 In William Shakespeare's "Macbeth", there is a character called "Sweno, the Norways' king" based on Svein.
Liðsmannaflokkr ("household troop's poem") is the title of a skaldic poem in ten stanzas describing the capture of London by Cnut the Great in 1016, preserved in "Óláfs saga helga" and "Flateyjarbók" (fol.
 186v), and in a shorter version in "Knýtlinga saga".
The Battle of Fýrisvellir was a battle for the throne of Sweden which was fought in the 980s on the plain called Fýrisvellir, where modern Uppsala is situated, between King Eric the Victorious and his nephew Styrbjörn the Strong.
 It is mentioned in a number of medieval sources, such as "Eyrbyggja saga", "Knýtlinga saga", "Hervarar saga" and Saxo Grammaticus' "Gesta Danorum" (Book 10), but the most detailed account is found in the short story "Styrbjarnar þáttr Svíakappa".
Southern Jutland (Danish: "Sønderjylland" ) is the name for the region south of the Kongeå in Jutland, Denmark and north of the Eider (river) in Schleswig-Holstein, Germany.
 The region north of the Kongeå is called Nørrejylland ("Northern Jutland").
 Both territories had their own ting assemblies in the Middle Ages (in Viborg and Urnehoved).
 Southern Jutland is mentioned for the first time in the Knýtlinga saga.
The Knútsdrápa by the skald Óttarr svarti (Óttar the Black) is one of the Old Norse poems composed for King Cnut. "
Knútsdrápur" (plural of "Knútsdrápa") are Old Norse skaldic compositions in the form of "drápur" which were recited for the praise of Cnut.
 Most of Óttarr's poem is cited in the "Knýtlinga saga", while one stanza is known only from other sources such as the "Heimskringla".
 It has been debated whether strophe 9 truly belongs to Óttarr's "Knútsdrápa" or to a poem which Óttarr composed for Cnut's father Svein Haraldsson.
Cnut the Great (Old Norse: "Knútr inn ríki"; c. 995 – 12 November 1035), also known as Canute - whose father was Sweyn Forkbeard (which gave him the patronym "Sweynsson", Old Norse: "Sveinsson") - was King of Denmark, England and Norway; together often referred to as the North Sea Empire.
 With the deaths of his heirs within a decade of his own, and Norman conquest of England in 1066, this legacy was mostly forgotten.
 He is popularly invoked in the context of the legend of "King Canute and the waves", which usually misrepresents him as a deluded monarch believing he has supernatural powers, contrary to the original legend which portrays a wise king who rebuked his courtiers for their fawning behaviour.
Northman (died 1017) was a Mercian chieftain of the early 11th century.
 A member of a powerful Mercian kinship (clan), he is known primarily for receiving the village of Twywell in Northamptonshire from King Æthelred II in 1013, and for his death by order of King Cnut the Great in 1017.
 His violent end by Cnut contrasts with the successful career enjoyed by his brother Leofric, as Earl of Mercia during Cnut's reign.
 Northman is believed to have been an associate of the troublesome ealdorman Eadric Streona, who was killed with him.
The Danish House of Knýtlinga (English: "House of Cnut's Descendants") was a ruling royal house in Middle Age Scandinavia and England.
 Its most famous king was Cnut the Great, who gave his name to this dynasty.
 Other notable members were Cnut's father Sweyn Forkbeard, grandfather Harald Bluetooth, and sons Harthacnut, Harold Harefoot, and Svein Knutsson.
 It has also been called the House of Canute, the House of Denmark, the House of Gorm, or the Jelling Dynasty.
Knýtlinga saga ("The Saga of Cnut's Descendants") is an Icelandic kings' saga written in the 1250s, which deals with the kings who ruled Denmark since the early 10th century.
