Rollo was a Viking who, as Count of Rouen, became the first ruler of Normandy, today a region in northern France. He emerged as the outstanding warrior among the Norsemen who had secured a permanent foothold on Frankish soil in the valley of the lower Seine. After the Siege of Chartres in 911, Charles the Simple, the king of West Francia, granted them lands between the mouth of the Seine and what is now Rouen in exchange for Rollo agreeing to end his brigandage, swearing allegiance to him, religious conversion and a pledge to defend the Seine's estuary from Viking raiders.
Ragnar Lodbrok, according to legends, was a Viking hero and a Swedish and Danish king. He is known from Old Norse poetry of the Viking Age, Icelandic sagas, and near-contemporary chronicles. According to traditional literature, Ragnar distinguished himself by conducting many raids against the British Isles and the Holy Roman Empire during the 9th century. He also appears in Norse legends, and according to the legendary sagas Tale of Ragnar's Sons and a Saga about Certain Ancient Kings, Ragnar Lodbrok's father has been given as the legendary king of the Swedes, Sigurd Ring.
Guthrum was King of East Anglia in the late 9th century. Originally a native of Denmark, he was one of the leaders of the "Great Summer Army" that arrived in Reading during April 871 to join forces with the Great Heathen Army, whose intentions were to conquer the kingdoms of Anglo-Saxon England. The combined armies were successful in conquering the kingdoms of East Anglia, Mercia, and Northumbria, and overran Alfred the Great's Wessex, but were ultimately defeated by Alfred at the Battle of Edington in 878. The Danes retreated to their stronghold, where Alfred laid siege and eventually Guthrum surrendered.
Gudfred was a ninth century Danish king who reigned from at least 804 to 810. Alternate spellings include Godfred (Danish), Göttrick (German), Gøtrik (Danish), Gudrød (Danish), and Godofredus (Latin). He stands at the threshold of the History of Denmark in the sense that he is the first ruler about whom there is substantial knowledge from contemporary sources. He waged offensive war against the Carolingian Empire with some success, but was murdered under murky circumstances before a major confrontation had taken place. There is no unambiguous trace of Gudfred in the later Norse sagas, and his history can only be traced from the hostile Frankish texts which makes an assessment of his role problematic. His paternity is unknown but he may have been closely related to Sigfred, who preceded him as king of Denmark c. 770–804. He was the uncle of the later Danish King Hemming (810–812) and the father of King Horik I (813–854).
Björn Ironside, according to Norse legends, was a Norse Viking chief and Swedish king. According to the 12th- and 13th-century Scandinavian histories, he was the son of notorious Viking king Ragnar Lodbrok and lived in the 9th century, between 855 and 858. Björn Ironside is said to have been the first ruler of the Swedish Munsö dynasty. In the early 18th century, a barrow on the island of Munsö was claimed by antiquarians to be Björn Järnsidas hög or Björn Ironside's barrow.
Sigurd Snake-in-the-eye or Sigurd Áslaugsson was a semi-legendary Viking warrior and Danish king active from the mid to late 9th century. According to multiple saga sources and Scandinavian histories from the 12th century and later, he is one of the sons of the legendary Viking Ragnar Lodbrok and Áslaug. His historical prototype might have been the Danish King Sigfred who ruled briefly in the 870s. Norwegian kings' genealogies of the Middle Ages name him as an ancestor of Harald Fairhair and used his mother's supposed ancestry the Völsung to create an ancestry between Harald and his descendants and Odin.
Halfdan Ragnarsson was a Viking leader and a commander of the Great Heathen Army which invaded the Anglo-Saxon kingdoms of England, starting in 865.
The Great Heathen Army, also known as the Viking Great Army, was a coalition of Scandinavian warriors who invaded England in AD 865. Since the late 8th century, the Vikings had been engaging in raids on centres of wealth, such as monasteries. The Great Heathen Army was much larger and aimed to conquer and occupy the four kingdoms of East Anglia, Northumbria, Mercia and Wessex.
Hastein was a notable Viking chieftain of the late 9th century who made several raiding voyages.
Harald 'Klak' Halfdansson was a king in Jutland around 812–814 and again from 819–827.
Ímar, synonymous with Ivar the Boneless, was a powerful Viking leader in Ireland and Scotland in the mid-late ninth century. He was the progenitor of the Uí Ímair dynasty, who would go on to dominate the Irish Sea region for several centuries. He was the son of the king of Lochlann, identified in the non-contemporary Fragmentary Annals of Ireland as Gofraid. The Fragmentary Annals name Auisle and Amlaíb Conung as his brothers. Another Viking leader, Halfdan Ragnarsson, is considered by some scholars to be another brother. The Irish Annals title Amlaíb, Ímar and Auisle "kings of the foreigners". Modern scholars use the title "Kings of Dublin" after the Viking settlement which formed the base of their power. Some scholars consider Ímar to be identical to Ivar the Boneless, a Viking commander of the Great Heathen Army named in contemporary English sources who also appears in the Icelandic sagas as the eldest son of the legendary Viking Ragnar Lodbrok by third wife Aslaug.
Horik II, also known as Hårik or, in late sources, Erik Barn, was King of the Danes from the fall of Horik I in 854 to an unknown date between 864 and 873. During his reign the Danish kingdom showed tendencies of breaking up. After his demise under unknown circumstances, Denmark entered a long period of obscurity, until the rise of the Jelling dynasty in the 10th century.
The First Viking Age in Ireland began in 795, when Vikings began carrying out hit-and-run raids on Gaelic Irish coastal settlements. Over the following decades the raiding parties became bigger and better organized; inland settlements were targeted as well as coastal ones; and the raiders built naval encampments known as longphorts to allow them to remain in Ireland throughout the winter. In the mid 9th century, Viking leader Turgeis or Thorgest founded a stronghold at Dublin, plundered Leinster and Meath, and raided other parts of Ireland. He was killed by the High King, Máel Sechnaill mac Máele Ruanaid, which was followed by several Irish victories against the Vikings and the seizure of Dublin in 849. Shortly after, a new group of Vikings known as the Dubgaill came to Ireland and clashed with the earlier Viking settlers, now called the Finngaill.
Viking Warrior is a young adult historical novel written by Judson Roberts in 2006. It is the first book of Judson's Strongbow Saga, set in the Viking Age. It was first published in 2006. The author claims to be a descendant of Rollo, a Viking who, in 911 AD, signed a treaty and received grants to the land which became Normandy.
The siege of Paris of 845 was the culmination of a Viking invasion of West Francia. The Viking forces were led by a Norse chieftain named "Reginherus", or Ragnar, who tentatively has been identified with the legendary saga character Ragnar Lodbrok. Reginherus's fleet of 120 Viking ships, carrying thousands of warriors, entered the Seine in March and sailed up the river.
Oistin mac Amlaíb was a ninth-century Norse or Norse-Gael leader whom sometimes identified as a King of Dublin. He was a son of Amlaíb Conung and nephew of Ímar, founder of the Uí Ímair dynasty. He is sometimes identified with Thorstein the Red, a figure who features in the Norse sagas.
The Battle of Strangford Lough was fought in 877 between two groups of rival Vikings described by the Irish Annals as the "fair heathens" and the "dark heathens". The Annals of Ulster describe "Albann", a figure usually identified with Halfdan Ragnarsson, a leader of the Great Heathen Army, as king of the "dark heathens", and Cogad Gáedel re Gallaib identifies Bárid mac Ímair, King of Dublin as the leader of the "fair heathens". All accounts agree Halfdan was killed in the battle, and Cogad Gáedel re Gallaib adds that Bárid was wounded in it.
Reginheri was a Viking leader in the early 9th century.
