Olaf I of Norway

Definition and stakes

William Hunt Dictionary of National Biography… (1887)

Olaf is sufficient reason for the unfavourable light in which he is represented by northern writers. From the more trustworthy songs of his contemporaries comes a picture of the king as a mighty ruler, wise, politic, and crafty, a lover of minstrelsy and a patron of poets. They exhibit a man endowed with a remarkable power of judging the characters of others, and of using them to forward his own interests. His craftiness is abundantly proved by his intrigues in Norway, and the natural cruelty and violence of his temper surely need no special proofs.

Portrait of Thomas Hodgkin Thomas Hodgkin The history of England, from the earliest times to the Norman Conquest (1906)

Two years after Olaf’s expulsion from the kingdom he returned (1030) , but fell in battle with his own hostile countrymen. When the inevitable reaction in favour of his memory set in, his body was carried to Trondhjem and buried under the high altar of the cathedral church. Miracles soon began to be wrought by his relics: there was a tide of pity and remorse for their fallen hero in the hearts of his people, who found themselves harshly dealt with by their Danish rulers. Before long Norway recovered her independence, and then Olaf was universally recognised as not only patriot but saint.

Robert Leighton Olaf the Glorious: A Story of the Viking Age

King Olaf met with no opposition in his endeavour to convert the people of Viken and Agder. In the district of Ringarike he christened a certain little boy, the son of Harald Groenske, who was of the race of Harald Fairhair. The king named the boy Olaf, and in giving him his blessing said that he would one day be a very great man. This same Olaf Haraldson afterwards became the King of Norway and a very great evangelist. He is known in history by the title of Olaf the Saint, and he is to this day regarded as the patron saint of Norway.
