There was a great man of noble family in Sweden called Steinkel. His mother's name was Astrith, the daughter of Njal the son of Fin the Squinter, from Halogaland; and his father was Rögnvald the Old. Steinkel was an Earl in Sweden at first, and then after the death of Eymund, the Swedes elected him their King. Then the throne passed out of the line of the ancient kings of Sweden. Steinkel was a mighty prince. He married the daughter of King Eymund. He died in his bed in Sweden about the time that King Harold fell in England.
Steinkel had a son called Ingi, who became King of Sweden after Haakon. Ingi was King of Sweden for a long time, and was popular and a good Christian. He tried to put an end to heathen sacrifices in Sweden and commanded all the people to accept Christianity; yet the Swedes held to their ancient faith. King Ingi married a woman called Mær who had a brother called Svein. King Ingi liked Svein better than any other man, and Svein became thereby the greatest man in Sweden. The Swedes considered that King Ingi was violating the ancient law of the land when he took exception to many things which Steinkel his father had permitted, and at an assembly held between the Swedes and King Ingi, they offered him two alternatives, either to follow the old order, or else to abdicate. Then King Ingi spoke up and said that he would not abandon the true faith; whereupon the Swedes raised a shout and pelted him with stones, and drove him from the assembly.
Svein, the King's brother-in-law, remained behind in the assembly, and offered the Swedes to do sacrifices on their behalf if they would give him the Kingdom. They all agreed to accept Svein's offer, and he was then recognised as King over all Sweden. A horse was then brought to the assembly and hewn in pieces and cut up for eating, and the sacred tree was smeared with blood. Then all the Swedes abandoned Christianity, and sacrifices were started again. They drove King Ingi away; and he went into Vestergötland. Svein the Sacrificer was King of Sweden for three years.
King Ingi set off with his retinue and some of his followers, though it was but a small force. He then rode eastwards by Småland and into Östergötland and then into Sweden. He rode both day and night, and came upon Svein suddenly in the early morning. They caught him in his house and set it on fire and burned the band of men who were within.
There was a baron called Thjof who was burnt inside. He had been previously in the retinue of Svein the Sacrificer. Svein himself left the house, but was slain immediately.
Thus Ingi once more received the Kingdom of Sweden; and he reestablished Christianity and ruled the Kingdom till the end of his life, when he died in his bed.
King Steinkel had, besides Ingi, another son Hallstein who reigned along with his brother. Hallstein's sons were Philip and Ingi, and they succeeded to the Kingdom of Sweden after King Ingi the elder. Philip married Ingigerth, the daughter of King Harold the son of Sigurth. He reigned for only a short time.
