Olaf Sihtricsson

Olaf Sihtricsson (d. 981), king of Deira (941–3, 949–52), king of Dublin (945–81). Olaf's father was Sihtric, king of Deira, whose second wife was Athelstan's sister. On Sihtric's death in 927, his brother Guthfrith took the throne (Olaf being a child), but was at once dispossessed by Athelstan. Olaf Guthfrithsson regained it in 939 and on his death in 941 was succeeded by Olaf Sihtricsson, who had married a daughter of Constantine, king of the Scots. He could not hold the territories regained from Edmund, Athelstan's successor, and was driven out of his capital, York, in 943. He did, however, recover the throne of the Norse kingdom of Dublin in 945, may have briefly been restored in York in 949, and was again dispossessed by Erik Bloodaxe in 952. He managed to hold his kingdom of Dublin in the face of incessant warfare against the Irish, but at the end of his life suffered a severe defeat at Tara (980), abdicated, and spent his last months on Iona.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
