Egil's Saga

Egil's Saga or Egill's saga (Old Norse: Egils saga;  listen ) is an Icelandic saga (family saga) on the lives of the clan of Egill Skallagrímsson (Anglicised as Egil Skallagrimsson), an Icelandic farmer, viking and skald. The saga spans the years c. 850–1000 and traces the family history from Egil's grandfather to his offspring.

Its oldest manuscript (a fragment) dates back to 1240 AD, and comprises the sole source of information on the exploits of Egil, whose life is not historically recorded. Stylistic and other similarities between Egil's Saga and Heimskringla have led many scholars to believe that they were the work of the same author, Snorri Sturluson. The work is generally referred to as Egla by Icelandic scholars.

The saga begins in Norway around 850, with the life of Egil's grandfather Ulf (Úlfr) aka Kveldulf or "Evening Wolf", and his two sons Thorolf (Þórólfr) and Skallagrim (Skalla-Grímr). Strife with the royal house drive the family out of the country, and they settle in Iceland. The brothers Egil and Throlf Skallagrimsson are born. They have a tenuous tenure in Norway, but Egil is outlawed and they roam Scandinavia and serve the king of England. Egil tries to reclaim property back in Norway (as his wife's inheritance), but this is blocked, and Egil develops a personal vendetta against King Eirik Bloodaxe.
