Hákon Sigurðsson

Haakon Sigurdsson, known as Haakon Jarl, was the de facto ruler of Norway from about 975 to 995. Sometimes he is styled as Haakon the Powerful, though the Ágrip and Historia Norwegiæ give the less flattering name Hákon Illi, that is, Haakon the Bad. He is also known as Hàkon Sigurðarson, Earl of Hlaðir.
