King Magnus V of Norway is killed at the Battle of Fimreite.

The Battle of Fimreite- The Battle of Fimreite (Norwegian: Slaget ved Fimreite) was a naval battle fought on June 15, 1184, between King Magnus Erlingsson and the Birkebeiner supported Sverre Sigurdsson. At this time in Norwegian history it was extremely common for there to be changes in leadership, and political coups were often conducted to establish a new ruler. This inevitably led to the naval battle between Sverre Sigurdsson and Magnus Erlingsson that resulted in Magnus being defeated and killed in the battle, and Sverre usurping the Norwegian throne. Similarly, this battle also had long lasting effects on Norway as a whole. As stated previously, Norway was very volatile during this time, however, the result of this battle led to the installation of Sverre and a lasting effect on Norway's leadership. Sverre would go on to rule from 1184 to 1202, making him one of the longest standing sovereign kings in Norway's twelfth and thirteenth century. His leadership along with Norways recent conversion to Christianity that spread the Administrative apparatus of the papacy would have long lasting effects on Norways culture, economy, and society.

Magnus V Erlingsson (Old Norse: Magnús Erlingsson, 1156 – 15 June 1184) was a king of Norway during the civil war era in Norway. He was the first Scandinavian monarch to be crowned in Scandinavia.
