Serkland
In Old Norse sources, such as sagas and runestones, Særkland or Serkland was the name of the Abbasid Caliphate and probably some neighbouring Muslim regions.
Despite the obvious similarity to Saracen, the place-name is likely derived from serkr (gown, modern Swedish "särk") and land (land, country), referring to the clothes of the people who lived in the area.
