Sverris saga is one of the Kings' sagas. Its subject is King Sverre Sigurdsson of Norway (r. 1177–1202) and it is the main source for this period of Norwegian history. As the foreword tells us, the saga in its final form consists of more than one part. Work first began in 1185 under the king’s direct supervision. It is not known when it was finished, but presumably it was well known when Snorri Sturluson began writing his Heimskringla in the 1220s since Snorri ends his account where Sverris saga begins. Thus the saga is contemporary or near-contemporary with the events it describes. The saga is obviously written by someone sympathetic to Sverre’s cause, but the strict demands of the genre ensure some degree of impartiality.[1] [2]
