- Monarch - Earl Eric Haakonsson then Earl Sweyn Haakonsson
The Norwegian monarch is the monarchical head of state of Norway, which is a constitutional and hereditary monarchy with a parliamentary system. The Norwegian monarchy can trace its line back to the reign of Harald Fairhair and the previous petty kingdoms which were united to form Norway; it has been in unions with both Sweden and Denmark for long periods.
Sweyn Haakonsson was an earl of the house of Hlaðir and co-ruler of Norway from 1000 to c. 1015. He was the son of earl Hákon Sigurðarson. He is first mentioned in connection with the battle of Hjörungavágr, where the Heimskringla says he commanded 60 ships. After the battle of Svolder in the year 1000, Sveinn became co-ruler of Norway with his half-brother, Eiríkr Hákonarson. After Eiríkr went to England in 1014, Sveinn was co-ruler with Hákon Eiríksson. In 1015, Óláfr Haraldsson arrived in Norway and claimed the throne. He defeated Sveinn and his allies in the battle of Nesjar. Sveinn retreated to Sweden, intending to muster a force to retake Norway but he died of an illness before he could return.
