Sweyn Haakonsson

Sweyn Haakonsson (Old Norse: Sveinn Hákonarson, Norwegian: Svein Håkonsson)[1] (died c. 1016) was an earl of the house of Hlaðir and co-ruler of Norway from 1000 to c. 1015.

After the battle of Svolder in the year 1000, Sveinn became co-ruler of Norway with his half-brother, Eiríkr Hákonarson.

Sveinn retreated to Sweden, intending to muster a force to retake Norway but he died of an illness before he could return.

Only one court-poet, Bersi Skáldtorfuson, is recorded as being in Sveinn's service and very little of his poetry has survived throughout history.

The Swedish historian Staffan Hellberg in 1972 claimed to be able to show that Sveinn was a fictitious person, and that he had never lived.
