Haakon Sigurdsson

Haakon Sigurdsson (Old Norse: Hákon Sigurðarson [ˈhɑːˌkon ˈsiɣˌurðɑz̠ˌson], Norwegian: Håkon Sigurdsson; c. 937–995), known as Haakon Jarl (Old Norse: Hákon jarl), was the de facto ruler of Norway from about 975 to 995. Sometimes he is styled as Haakon the Powerful (Old Norse: Hákon jarl hinn ríki), though the Ágrip and Historia Norwegiæ give the less flattering name Hákon Illi, that is, Haakon the Bad.
