Hakon Sunnivasson

Hakon Sunnivasson (Danish: Hakon Jyde, "from Jutland") (fl. 1131) was a Danish nobleman and the father of Eric III of Denmark.

Hakon was the son of a Danish nobleman and Sunniva, a Norwegian and the granddaughter of Magnus the Good. He was married to Ragnhild, the daughter of Eric I of Denmark, according to Saxo Grammaticus because he had avenged the murder of Eric's brother Bjørn, and he may have served as the king's jarl in the border region. In 1131, he was initially part of the conspiracy against his brother-in-law Canute Lavard, but he withdrew when the plans turned towards murder. Because he was bound by oath, he could not warn Canute.
