Eidsivating (Old Norse: Heiðsævisþing) was one of the four ancient popular assemblies or things (lagting) of medieval Norway.
Historically, it was the site of court and assembly for the eastern parts of Norway, and was located at Eidsvoll.
Eidsivating was originally situated at Åker gård, the seat of Vang in Hedmark county, Norway.
When Norway was united as a kingdom, the four independent lagting – Frostating, Gulating, Borgarting, and Eidsivating – were the most supreme bodies of law, acting as both legislative assemblies and courts.
[2] These were representative assemblies at which delegates from the various districts in each region met to award legal judgments and pass laws (Eidsivatingsloven).
