Magnus Erikssons landslag
The Magnus Erikssons landslag also called only Landslagen was a Swedish law passed by king Magnus IV in circa 1341.
It was the first attempt to a law applying to the entire nation of Sweden, replacing the previous local county laws of the Medieval Scandinavian law.
The Country Law applied to the entire countryside, but not to the cities, which were governed according to the Stadslagen, which were issued in about the same time, but was a separate law. The Law from 1350 were followed by the Kristofers landslag of 1442, but as they were used in parallel, it was not replaced by it.
It was in effect in Sweden until the Civil Code of 1734.
