Svein Knutsson (Old Norse: Sveinn Knútsson [ˈswɛinː ˈknuːtsˌson]; c. 1016–1035) was the son of Cnut the Great, king of Denmark, Norway, and England, and his first wife Ælfgifu of Northampton, a Mercian noblewoman.
[1][2][3][4] Svein Knutsson is also mentioned as Sveinn Alfífuson (matronym) and under the epithet óforsynjukonungr ("unforeseen king").
At Christmas every farmer had to give the king a measure (between 15 and 20 litres) of malt from every hearth and the thigh of a three-year-old ox, this was called vinjartodde (land tax) in Old Norse, and also a bucket of butter.
Sveinn and his forces made their way south to Agder, believing that Tryggve would attempt to slip through the Skagerrak and join his supporters in Viken.
Later that same winter Kalv Arnesson and Einar Tambarskjelve met and decided to travel to Gardarike to fetch Olav Haraldsson's son Magnus.
