Sweyn Forkbeard was King of Denmark from 986 until his death, King of England for five weeks from December 1013 until his death, and King of Norway from 999/1000 until 1013/14. He was the father of King Harald II of Denmark, King Cnut the Great, and Queen Estrid Svendsdatter.
Cnut, also known as Canute and with the epithet the Great, was King of England from 1016, King of Denmark from 1018, and King of Norway from 1028 until his death in 1035. The three kingdoms united under Cnut's rule are referred to together as the North Sea Empire.
Harald "Bluetooth" Gormsson was a king of Denmark and Norway.
Ragnar Lodbrok, according to legends, was a Viking hero and a Swedish and Danish king.
Gorm the Old, also called Gorm the Languid, was ruler of Denmark, reigning from c. 936 to his death c. 958 or a few years later. He ruled from Jelling, and made the oldest of the Jelling stones in honour of his wife Thyra. Gorm was born before 900 and died perhaps around 958 or possibly 963 or 964.
Eric the Victorious was a Swedish monarch as of around 970. Although there were earlier Swedish kings, he is the first Swedish king in a consecutive regnal succession, who is attested in sources independent of each other, and consequently Sweden's list of rulers usually begins with him. His son Olof Skötkonung, however, is considered the first ruler documented to definitely have been accepted both by the original Swedes around Lake Mälaren and by the Geats around Lake Vättern. Adam of Bremen reports a king named Emund Eriksson before Eric, but it is not known whether he was Eric's father. The Norse sagas' accounts of a Björn Eriksson are considered unreliable.
Anund Jacob or James was King of Sweden from 1022 until around 1050. He is believed to have been born on 25 July, in either 1008 or 1010 as Jakob, the son of King Olof Skötkonung and Queen Estrid. Being the second Christian king of the Swedish realm, his long and partly turbulent reign saw the increasing dissemination of Christianity as well as repeated attempts to influence the balance of power in Scandinavia. Throughout his reign, he tried to subvert the rising Danish hegemony in Scandinavia by supporting the Norwegian monarchy. He also supported the reign of Yaroslav the Wise in Kievan Rus, his brother-in-law. He is referred to in positive terms in German and Norse historical sources. His reign was one of the longest in Sweden during the Viking Age and Middle Ages.
Emund the Old or Edmund was King of Sweden from c. 1050 to c. 1060. His short reign was characterised by disputes with the Archbishopric of Bremen over church policies, and a historically debated delimitation of the Swedish-Danish border.
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.
Harthacnut or Cnut I was a semi-legendary King of Denmark. The old Norse story Ragnarssona þáttr makes Harthacnut son of the semi-mythic viking chieftain Sigurd Snake-in-the-Eye, himself one of the sons of the legendary Ragnar Lodbrok. The saga in turn makes Harthacnut the father of the historical king, Gorm. It has been suggested he is to be identified with the Hardegon of Northmannia whose early-10th century conquest of Denmark was related by Adam of Bremen.
Olof was, according to Adam of Bremen, a Swedish chieftain who conquered Denmark c. 900 and founded the House of Olaf. Evidence for his historicity is only circumstantial, since he belongs to a period of Danish history when very little is known from textual sources.
Gyrd and Gnupa were kings of Denmark in the 10th century according to Sweyn II of Denmark and Adam of Bremen. They were the sons of the Swedish chieftain Olof the Brash who had conquered Denmark and they ruled together according to Swedish tradition.
The two Sigtrygg Runestones, designated as DR 2 and DR 4 in the Rundata catalog, are two of the Hedeby stones that were found in Schleswig-Holstein, Germany, which during the Viking Age was part of Denmark. The runestones were raised after the Danish king Sigtrygg Gnupasson by his mother Ásfriðr. Together with the account of Adam of Bremen, the two inscriptions constitute evidence for the House of Olaf on the Danish throne.
Tryggevælde Runestone, designated as DR 230 under Rundata, is a runestone housed in the National Museum of Denmark, in Copenhagen. It is classified as being carved in runestone style RAK, and is dated to about 900 CE.
Nordalbingia was one of the four administrative regions of the medieval Duchy of Saxony, the others being Angria, Eastphalia, and Westphalia. The region's name is based on the Latin name Alba for the Elbe River and refers to an area predominantly located north of the Lower Elbe, roughly corresponding with the present-day Holstein region. Situated in what is now Northern Germany, this is the earliest known dominion of the Saxons.
The Viking runestones are runestones that mention Scandinavians who participated in Viking expeditions. This article treats the runestone that refer to people who took part in voyages abroad, in western Europe, and stones that mention men who were Viking warriors and/or died while travelling in the West. However, it is likely that all of them do not mention men who took part in pillaging. The inscriptions were all engraved in Old Norse with the Younger Futhark. The runestones are unevenly distributed in Scandinavia: Denmark has 250 runestones, Norway has 50 while Iceland has none. Sweden has as many as between 1,700 and 2,500 depending on definition. The Swedish district of Uppland has the highest concentration with as many as 1,196 inscriptions in stone, whereas Södermanland is second with 391.
Gunhilda of Wenden was a Polish princess, daughter of Mieszko I of Poland according to Chronicles of Thietmar of Merserburg, Adam von Bremen and Acta Cnutonis regis princess and Danish Viking Age queen consort, the supposed spouse of 10th-century King Sweyn I of Denmark. The sources about the wife or wives of Sweyn are contradictory, and historians have debated whether she is the Polish Świętosława given another name in Norse sources.
Gunnhildr Sveinsdóttir or Gunnhildr Haraldsdóttir, Guda or Gyda was, according to the traditional view, a queen consort of King Anund Jacob of Sweden and of king Sveinn II of Denmark. However, the sources are so vague that several modern historians maintain that there were actually two queens of that name, of Sweden and Denmark respectively. She is sometimes called Gude or Gyridje, but this is probably because of confusion with her daughter, Gyda, who is also known under her mother's name Gunnhildr.
