Sweyn Asleifsson
1170
Sweyn Asleifsson or Sveinn Ásleifarson (c. 1115 – 1171) was a twelfth-century Viking who appears in the Orkneyinga Saga ... Sweyn was born in Caithness in the early twelfth century, to Olaf Hrolfsson and his wife Åsleik. According to the Orkneyinga Saga, he came to prominence when he murdered Earl Paul of Orkney's cup-bearer c. 1134 in a quarrel over a drinking game, and fled to Tiree to take refuge with Holdbodi Hundason ... The circumstances of Sweyn's death are confused. It is clear that the events described in the saga are those of the brief recapture of Dublin from the Normans by its last Scandinavian king, Ascall mac Ragnaill, in 1171: but there are many discrepancies between the Orcadian and Anglo-Norman accounts. It is possible that the warlord referred to by Giraldus Cambrensis as "John the Furious" was none other than Sweyn. Be that as it may, when the Normans retook Dublin, both Sweyn and Hakon were killed.
