The ÃÂstgötalagen was a medieval provincial law-code for ÃÂstergötland and the SmÃÂ¥land lands of Kinda (which also included Ydre härad), Vedbo, Tjust and several smaller areas, as well as ÃÂland, an area known as the ÃÂstgöta lagsaga. The law-code was associated with assemblies called Lionga thing.
The preserved record clearly relates to the lawspeakers' orally transmitted laws and is considered to have been written down around 1290.
The ÃÂstgötalagen were first printed by Hans Samuel Collin and Carl Johan Schlyter in 1830. A modernized Swedish interpretation with comments was published in 1933 by àke Holmbäck and Elias Wessén.
