Sweden
The Swedish provincial laws(in Swedish landskapslag) were the means of law holding in Sweden during the Middle Ages. The provinces of Sweden, or landskap were practically separate countries and had individual laws.
Provincial laws are known to have existed in the provinces of Västergötland, Östergötland, Dalarna, Hälsingland, Södermanland, Uppland, Västmanland, Värmland and Närke. A provincial law also existed for Gotland, Gutalagen.
In older times the laws were memorized by a lawspeaker (lagman). Around 1200 the laws began to be transferred to written form. This was probably due to clerical influences.
The oldest of the Swedish provincial laws is the Westrogothic law or Västgötalagen, which was used in the province of Västergötland, in west Sweden. Like Gutalagen, it was written in its oldest version around 1220. Some regulations are likely to have their origins in the Viking Age. A stipulation that "no man may inherit while he sits in Greece", for instance, would have been useful during the Viking Age when many Swedes served in the Varangian Guard but less so when the laws were codified, at a time when such service had all but stopped.
Of the fine, one third was to be paid to the wronged; one third to the hundred; and one third to the King.
Around 1350, the Swedish provincial laws were replaced by a country law, the Magnus Eriksson country law. Gutalagen was in use until 1595 and the Scanian Law was in use until 1683.
