Information: - Gunhilda of Wenden was a semi-legendary Polish or other Slavic princess and Danish Viking age queen consort, the supposed spouse of 10th-century King Sweyn I of Denmark (9861014). - Estrid Svendsdatter of Denmark ( Estrith , Astrith : 990/997 -- 1057/1073 ) , was a Danish princess and titular Queen , a Russian princess and , possibly , Duchess of Normandy by marriage . She was the daughter of Sweyn Forkbeard and perhaps Gunhild of Wenden and sister of Cnut the Great . By Ulf Jarl , she was the mother of the later King Sweyn II Estridson and Beorn Estrithson . The dynasty that ruled Denmark in 1047 -- 1412 was named after her . She was known in Denmark as Dronning Estrid , ( Queen Estrid ) , despite the fact that she was not married to a King and not a queen regnant . According to other researchers Estrid was the daughter of Sweyn Forkbeard and Sigrid the Haughty , herself the daughter of Skagul Toste , making Olof Skotkonung , the son of Sigrid the Haughty and Eric the Victorious , Estrid 's half - brother and Canute the Great , Harald and witosawa her other half - siblings , as children of Sweyn Forkbeard and the Polish princess Gunhild , daughter of Mieszko I of Poland . - A queen consort is the wife of a reigning king (or an empress consort in the case of an emperor). In Brunei, the wife of the Sultan is known as a "Raja Isteri" with prefix "Pengiran Anak", equivalent with queen consort in English, as were the consorts of tsars when Bulgaria was still a monarchy. A queen consort usually shares her husband's social rank and status. She holds the feminine equivalent of the king's monarchical titles, but historically, she does not share the king's political and military powers. A queen regnant is a queen in her own right with all the powers of a monarch, who (usually) has become queen by inheriting the throne upon the death of the previous monarch. - King Cnut the Great (Old Norse: "Knutr inn riki"; c. 995 12 November 1035), also known as Canute, was King of Denmark, England, and Norway, together often referred to as the Anglo-Scandinavian or North Sea Empire. After his death, the deaths of his heirs within a decade, and the Norman conquest of England in 1066, his legacy was mostly forgotten. The medieval historian Norman Cantor stated that he was "the most effective king in Anglo-Saxon history", although Cnut himself was Danish and not a Briton or Anglo-Saxon. - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux. - The Duchy of Normandy grew out of the 911 Treaty of Saint-Clair-sur-Epte between King Charles III of West Francia and Rollo, leader of the Vikings. From 1066 until 1204 it was held by the kings of England, except for the brief rule of Robert Curthose (10871106) and Geoffrey Plantagenet (11441150). Normandy was declared forfeit by Philip II of France in 1202, and seized by force of arms in 1204. It remained disputed territory until the Treaty of Paris of 1259, when the English sovereigns ceded their claim, except for the Channel Islands. - The Anglo-Saxon Chronicle is a collection of annals in Old English chronicling the history of the Anglo-Saxons. The original manuscript of the "Chronicle" was created late in the 9th century, probably in Wessex, during the reign of Alfred the Great. Multiple copies were made of that one original and then distributed to monasteries across England, where they were independently updated. In one case, the "Chronicle" was still being actively updated in 1154. - The Viking Age is the period from late 8th century to mid 11th century in European history, especially Northern European and Scandinavian history, following the Germanic Iron Age. It is the period of history when Scandinavian Norsemen explored Europe by its seas and rivers for trade, raids, colonisation and conquest. In this period, the Norsemen settled in Norse Greenland, Newfoundland, and present-day Faroe Islands, Iceland, Norway, Scotland, England, Ireland, the Netherlands, Germany, Ukraine, Russia, and Turkey. Though Viking travellers and colonists were seen at many points in history as brutal raiders, many historical documents suggest that their invasion of other countries was retaliation in response to the encroachment upon tribal lands by Christian missionaries, and perhaps by the Saxon Wars prosecuted by Charlemagne and his kin to the south, or, were motivated by overpopulation, trade inequities, and the lack of viable farmland in their homeland. Information about the Viking Age is drawn largely from what was written about the Vikings by their enemies, and primary sources of archaeology, supplied with secondary sources like the Icelandic Sagas. - Normandy (pronounced , Norman: "Normaundie", from Old French "Normanz", plural of "Normant", originally from the word for "northman" in several Scandinavian languages) is one of the regions of France, roughly corresponding to the historical Duchy of Normandy. - Sweyn Forkbeard (Old Norse: "Sveinn Tjuguskegg"; Danish: "Svend Tveskg"; 960 3 February 1014) was king of Denmark, England, and parts of Norway. His name appears as Swegen in the "Anglo-Saxon Chronicle". He was the son of King Harald Bluetooth of Denmark, and the father of Cnut the Great.
