Feud in the Icelandic Saga:

Feud stands at the core of the Old Icelandic sagas. Jesse Byock shows how the dominant concern of medieval Icelandic society--the channeling of violence into accepted patterns of feud and the regulation of conflict--is reflected in the narrative of the family sagas and the Sturlunga saga compilation. This comprehensive study of narrative structure demonstrates that the sagas are complex expressions of medieval social thought.
