Description

Haakon Ericsson (Old Norse: Hákon Eiríksson, Norwegian: Håkon Eiriksson) was Earl of Lade and governor of Norway as a vassal under Cnut the Great.

Håkon Eiriksson was from a dynasty of Norwegian rulers in the eastern part of Trondheim, bordering the Trondheimsfjord. He was the son of Eirik Håkonson, ruler of Norway and earl of Northumbria. His mother is commonly believed to have been Gytha, a daughter of Sweyn Forkbeard and Sigrid the Haughty of Denmark and half-sister of King Cnut.

As his father's successor in Norway, Håkon Eiriksson ruled as a Danish vassal from 1012 to 1015, with Einar Tambarskjelve as his aide and his uncle, Sveinn Hákonarson, holding some areas as a Swedish vassal. After some years' absence in England fighting the Danes, Olaf Haraldsson returned to Norway in 1015 and declared himself king, obtaining the support of the petty kings of the Uplands. In 1016, Olaf defeated Sveinn Hákonarson at the Battle of Nesjar. After the victory of Olaf Haraldsson, Håkon fled to England where he was well received by King Knut and made Earl of Worcester. After the Battle of the Helgeå, Norwegian nobles rallied behind Cnut.

He is recorded as being the ruler of the Sudreyar from 1016 until 1030. In 1028, Håkon Eiriksson returned as Knut's vassal ruler of Norway. Håkon died in a shipwreck in the Pentland Firth, between the Orkney Islands and the Scottish mainland, either late 1029 or early 1030.

Sweyn Haakonsson (Old Norse: Sveinn Hákonarson, Norwegian: Svein Håkonsson) 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.
