Magnus Olafsson (Old Norse: Magnús Óláfsson, Norwegian and Danish: Magnus Olavsson; c. 1024 – 25 October 1047), better known as Magnus the Good (Old Norse: Magnús góði, Norwegian and Danish: Magnus den gode), was the King of Norway from 1035 and King of Denmark from 1042, ruling over both countries until his death in 1047.

He was an illegitimate son of Olaf II of Norway, but fled with his mother when his father was dethroned in 1028. He returned to Norway in 1035 and was crowned king at the age of 11. In 1042, he was also crowned king of Denmark. Magnus ruled the two countries until 1047, when he died under unclear circumstances. After his death, his kingdom was split between Harald Hardrada in Norway and Sweyn Estridsson in Denmark.

Early life

Magnus was an illegitimate son of King Olaf Haraldsson (later St. Olaf), by his English concubine Alfhild,[1] originally a slave (thrall) of Olaf's queen Astrid Olofsdotter.[2] Born prematurely, the child was weak and unable to breathe for the first few minutes, and he was probably not expected to survive. Olaf was not present at the child's birth, and his Icelandic skald Sigvatr Þórðarson became his godfather. In a hasty baptism, Sigvatr named Magnus after the greatest king he knew of, also Olaf's greatest role model, Karla Magnus, or Charlemagne. Against the odds, Magnus went on to grow strong and healthy, and he became of vital importance to Olaf as his only son.[3]

[26].Harald FairhairMagnus' ancestry according to the sagas, although scholars now doubt that he was directly descended from


Magnus was not married, but had a daughter out of wedlock, Ragnhild, who married Haakon Ivarsson, a Norwegian nobleman.[14] Her great-grandson would become King Eric III of Denmark.

The line of Olaf II ended with Magnus' death. However, in 1280 Eric II of Norway, who was descended through his mother from Magnus' legitimate sister, Wulfhild, was crowned king of Norway.


of middle height, with regular features and light complexion. He had light blond hair, was well-spoken and quick to make up his mind, was of noble character, most generous, a great warrior, and most valorous."[25]
describes Magnus as: Snorri

Physical appearance

Sweyn increased the pressure on Magnus from his base in Scania,[11] but by late 1046, Magnus had driven Sweyn out of Denmark. However, on October 25, 1047 he died suddenly while in Denmark, either in Zealand or in Jutland, either in an accident or of a disease; accounts vary.[23] Reports include falling overboard from one of the ships he was mustering to invade England and drowning,[13] falling off a horse,[14][24] and falling ill while on board a ship.[1] He is said to have made Sweyn his heir in Denmark, and Harald in Norway; some say in a deathbed statement.[1] Magnus was buried with his father in the cathedral at Nidaros, modern Trondheim.[1]

Meanwhile, Magnus' uncle Harald Hardrada had returned to Norway from the east and contested his rule there, while Sweyn was still a threat in Denmark; Harald allied himself with Sweyn.[1][14] Magnus chose to appease Harald,[1] and made him his co-king in Norway in 1046.[21][22]

Magnus wanted to reunite Cnut the Great's entire North Sea Empire by also becoming king of England. When Harthacnut died, the English nobles had chosen as their king Æthelred the Unready's son Edward (later known as Edward the Confessor); Magnus wrote to him that he intended to attack England with combined Norwegian and Danish forces and "he will then govern it who wins the victory."[19] The English were mostly hostile to Magnus; Sweyn was made welcome there, although Edward's mother, Emma, curiously favored Magnus and in 1043 the king confiscated her property, with which by one report she had promised to assist Magnus.[20]

Sweyn continued to oppose Magnus in Denmark, although according to Heimskringla, they reached a settlement by which Sweyn became Earl of Denmark under Magnus.[18]

As part of consolidating his control, Magnus destroyed the Jomsvikings. Sweyn fled east and returned as one of the leaders of an invasion by the Wends in 1043, which Magnus decisively defeated at the Battle of Lyrskov Heath, near Hedeby.[13][15] In the battle, Magnus wielded Saint Olaf's battle-axe, named Hel after the goddess of death.[13][16] He had dreamt of his father the night before, and the Norwegians swore that before the battle they could hear the bell that Saint Olaf had given to the Church of St. Clement in Kaupang, in Nidaros - a sign that the saint was watching over his son and the army.[17] It was the greatest victory ever over the Wends, with up to 15,000 killed.

Another son of Cnut, Harthacnut, was on the throne of Denmark and wanted his country to reunite with Norway, while Magnus initiated a campaign against Denmark around 1040.[11] However, the noblemen of both countries brought the two kings together at the Göta River, the border between their kingdoms. They made peace and agreed that the first of them to die would be succeeded by the other.[12][13] In 1042 Harthacnut died while in England, and Magnus also became King of Denmark, in spite of a claim by Cnut's nephew Sweyn Estridsen, whom Harthacnut had left in control of Denmark when he went to England,[12][14] and who had some support.

Magnus was proclaimed king in 1035, at 11 years of age, and Svein and his mother fled; Svein died shortly after. At first Magnus sought revenge against his father's enemies, but on Sigvatr's advice he stopped doing so, which is why he became known as "good" or "noble".[9]

King of Norway and Denmark

In early 1031, a party including Magnus's uncle Harald Sigurdsson (later also to be king and then known as Harald Hardrada) arrived to report the news of his father's death at the Battle of Stiklestad. For the next few years, Magnus was educated in Old Russian and some Greek and was trained as a warrior.[6] After Cnut's death in 1035, the Norwegian noblemen did not want to be under the oppressive rule of his son Svein and his mother Ælfgifu (known as Álfífa in Norway) any longer.[7] Einar Thambarskelfir and Kalf Arnesson, who had both sought to be appointed regents under Cnut after Olaf's death in 1030 (Cnut instead appointed Svein and Ælfgifu),[8] went together to Kievan Rus' to bring the boy back to rule as the King of Norway.[9] After receiving the approval of Ingegerd, they returned with Magnus to Sigtuna in early 1035, and received backing from the Swedish king, brother of Magnus's stepmother Astrid. Astrid immediately became an important supporter of Magnus, and an army was gathered in Sweden, headed by Einar and Kalf, to place Magnus on the Norwegian throne.[10]

[5].Ingegerd, Cnut's regent in Norway, had disappeared at sea, and gathered his men to make a swift return to Norway. Magnus was left to be fostered by Yaroslav and his wife Håkon Eiriksson Earl of Lade. Yaroslav, however, did not want to become directly involved in the Scandinavian power-struggles, and declined to help. After some time, in early 1030, Olaf learned that the Yaroslav the Wise), where Olaf sought assistance from Grand Prince Holmgard (Novgorod From there they travelled southwards to [4]
