Answer
Agents of the King of Norway assassinated Snorri Sturluson, a famed Icelandic historian, and politician, in 1241. Snorri's influential works, including the Prose Edda and the Heimskringla, compiled and preserved Norse mythology and sagas. His assassination stemmed from political conflicts during Norway's civil war era, in which Snorri supported factions opposed to King Håkon IV.
