List of Norwegian monarchs in the context of "Heimskringla"

Harald Sigurdsson (Old Norse: Haraldr Sigurðarson; c. 1015 – 25 September 1066), also known as Harald III of Norway and given the epithet Hardrada in the sagas, was King of Norway from 1046 to 1066. He unsuccessfully claimed the Danish throne until 1064 and the English throne in 1066. Before becoming king, Harald spent 15 years in exile as a mercenary and military commander in Kievan Rus' and chief of the Varangian Guard in the Byzantine Empire. In his chronicle, Adam of Bremen called him the "Thunderbolt of the North".

In 1030, the fifteen-year-old Harald fought in the Battle of Stiklestad alongside his half-brother Olaf Haraldsson. Olaf sought to reclaim the Norwegian throne, which he had lost to Danish king Cnut two years previously. Olaf and Harald were defeated by forces loyal to Cnut, and Harald was forced into exile to Kievan Rus'. Thereafter, he was in the army of Grand Prince Yaroslav the Wise, becoming captain, until he moved on to Constantinople with his companions around 1034. In Constantinople, he rose quickly to become the commander of the Byzantine Varangian Guard, seeing action on the Mediterranean Sea, in Asia Minor, Sicily, possibly in the Holy Land, Bulgaria and in Constantinople itself, where he became involved in the imperial dynastic disputes. Harald amassed wealth whilst in the Byzantine Empire, which he shipped to Yaroslav in Kievan Rus' for safekeeping. In 1042, he left the Byzantine Empire, returning to Kievan Rus' to prepare to reclaim the Norwegian throne. In his absence the Norwegian throne had been restored from the Danes to Olaf's illegitimate son Magnus the Good.

Margaret I (Danish: Margrete Valdemarsdatter; March 1353 – 28 October 1412) was Queen regnant of Denmark, Norway, and Sweden (which included Finland) from the late 1380s until her death, and the founder of the Kalmar Union that joined the Scandinavian kingdoms together for over a century. She had been queen consort of Norway from 1363 to 1380 and of Sweden from 1363 to 1364 by marriage to Haakon VI. Margaret was known as a wise, energetic and capable leader, who governed with "farsighted tact and caution", earning the nickname "Semiramis of the North". Also known famously and derisively as "King Breechless", one of several derogatory nicknames once thought to have been invented by her rival Albert, King of Sweden, she was also called "Lady King" by her subjects, widely used in recognition of her capabilities. Knut Gjerset calls her "the first great ruling queen in European history".

The youngest daughter of Valdemar IV of Denmark, Margaret was born at Søborg Castle. She was a practical, patient administrator and diplomat, albeit one of high aspirations and a strong will, who intended to unite Scandinavia forever into one single entity with the strength to resist and compete against the might of the Hanseatic League. In 1363, aged ten, Margaret married Haakon VI. In 1370, they had a son, Olaf. Following the deaths of her husband and son, Margaret was proclaimed queen of the Scandinavian kingdoms. She was ultimately succeeded by a grandnephew, Erik of Pomerania. Although Erik came of age in 1401, Margaret continued for the remaining 11 years of her life to be sole ruler in all but name. Her regency marked the beginning of a Dano-Norwegian union which was to last for more than four centuries.

Members of the Norwegian royal family are people related to King Harald V of Norway or former Norwegian monarchs who are royals and who hold royal titles. The term does not include non-royal relatives. The current family who holds the throne are members of the House of Glücksburg who ascended to the Norwegian throne after the election of Prince Carl of Denmark as King of Norway (regnal name Haakon VII) during the dissolution of the Swedish-Norwegian union in 1905.

The Norwegian monarch holds the title King of Norway while his Royal consort is Queen of Norway with the style Majesty. The heir apparent to the Norwegian throne holds the title Crown Prince of Norway while his wife is Crown Princess of Norway with the style Royal Highness. The children of the reigning Monarch and the children of the heir apparent are granted the title Prince of Norway or Princess of Norway. Only the eldest child is a Royal Highness, while the others do not have any styles in Norwegian, although the style of Highnesses may be used informally in foreign languages.

Eric Haraldsson (Old Norse: Eiríkr Haraldsson [ˈɛiˌriːkz̠ ˈhɑrˌɑldsˌson], Norwegian: Eirik Haraldsson; fl. c.930−954), nicknamed Bloodaxe (Old Norse: blóðøx [ˈbloːðˌøks], Norwegian: Blodøks) and Brother-Slayer (Latin: fratrum interfector), was a Norwegian king. He ruled as King of Norway from 932 to 934, and twice as King of Northumbria: from 947 to 948, and again from 952 to 954.

Frederick IV (Danish: Frederik; 11 October 1671 – 12 October 1730) was King of Denmark and Norway from 1699 until his death. Frederick was the son of Christian V of Denmark-Norway and his wife Charlotte Amalie of Hesse-Kassel.

Saint Olaf (c. 995 – 29 July 1030), also called Olaf the Holy, Olaf II, Olaf Haraldsson, and Olaf the Stout or "Large", was King of Norway from 1015 to 1028. Son of Harald Grenske, a petty king in Vestfold, Norway, he was posthumously given the title Rex Perpetuus Norvegiae (English: Eternal/Perpetual King of Norway) and canonised at Nidaros (Trondheim) by Bishop Grimketel, one year after his death in the Battle of Stiklestad on 29 July 1030. His remains were enshrined in Nidaros Cathedral, built over his burial site. His sainthood encouraged the widespread adoption of Christianity by Scandinavia's Vikings/Norsemen.

Pope Alexander III confirmed Olaf's local canonisation in 1164, making him a recognised saint of the Catholic Church, and Olaf started to be known as Rex Perpetuus Norvegiae – eternal king of Norway. Following the Reformation, he was a commemorated historical figure among some members of the Lutheran and Anglican Communions.
