Biography
Harald Grenske (c. 952–995) was a minor king in Vestfold, Norway, born in Tønsberg. He was the son of Gudrød Bjørnsson, who was said to be a grandson of Harald Fairhair and king of Vestfold. The name 'Grenske' comes from Grenland, where he grew up.
When Harald was about eleven, his father Gudrød was killed by Gunnhild Gormsdóttir's sons, including Harald Greyhide and his brothers, who were fighting for control of Norway. Harald had to flee and first went to Oppland, then to Sweden, where he was taken in by the powerful chieftain Skagul Toste. Together, they went on Viking raids, mainly around the Baltic Sea. This time helped Harald become a skilled warrior and leader.
After Gunnhild's sons were eventually ousted from Norway, Harald Grenske joined forces with Haakon Sigurdsson, who governed Norway under the Danish king Harald Bluetooth. In this role, Harald took back control of Vestfold and Agder as a petty king. He married Åsta, the daughter of Gudbrand Kula, and they had a son who became very significant in history.
However, Harald later left Åsta to pursue Sigrid the Haughty, the daughter of his former protector Skagul Toste and the wealthy widow of Eric the Victorious of Sweden. Sigrid had large estates in Svithjod and was considered a highly sought-after match. Tired of Harald's persistent advances, she set up a feast for Harald and another suitor, Vissevald from Gardarike (Novgorod), and had both men burned inside the hall to discourage other unwanted suitors. Harald died in Sweden, likely around 995.
Harald's widow Åsta gave birth shortly after his death to Olaf Haraldsson, who later became King of Norway and the country's patron saint, known as Saint Olaf. Åsta later married Sigurd Syr, king of Ringerike. No records from Harald's time mention him, and his story comes only from later sagas, mainly Snorri Sturluson's Olav Trygvasons saga, which refers to Harald as king of Vingulmark, Vestfold, and Agder. Modern scholars have questioned the accuracy of several details about Harald's life.
Before Fame
Harald Grenske was born around 952 in Tønsberg, into the royal family of Vestfold, linked to Harald Fairhair, the first king to unite much of Norway. His early life was marked by violence and upheaval: his father was murdered by Gunnhild Gormsdóttir's politically ambitious sons, forcing him to flee at around age eleven. This chaotic period came during a time of intense struggle for control in Norway, with rival factions vying for power.
While in exile in Sweden, Harald was sheltered and mentored by the influential Skagul Toste. His time on Viking expeditions in the Baltic Sea region provided him with the military skills and allies needed to return to Norway and regain kingship over Vestfold and Agder when the political situation became favorable.
