The Hervarar saga tells that Inge died…
1105 CE
The Hervarar saga tells that Inge died of old age and that he ruled until his death.
The exact date of his death is not known, but he probably died around 1105.
Inge’s grave is most likely a set of remains found in Vreta Abbey in a section of the abbey church that was erected by Inges son Ragnvald.
All skeletons that are likely to be that of Inge are very tall, about two meters in length, suggesting that Snorri's description was accurate.
As Inge's son, Ragnvald, had died before he could succeed his father on the throne, Inge is succeeded by his two nephews, Philip Halstensson and Inge the Younger, who are the sons of his elder brother Halsten Stenkilsson.
