Magnus I of Sweden (1240 – 1290), often called Ladulås: Barnlock, was king of Sweden from 1275/1280 until his death in 1290. Later historians ascribe his epithet to a decree of 1279 freeing the Yeomanry from the duty to provide sustenance for travelling Nobles and Bishops ("Peasants! Lock your barns!), but probably its simply a corruption of Ladislaus.
With the Alsnö stadga about 1279, Magnus III gave anyone who supported the Crown with a knight and a horse freedom from certain taxes (such a freedom was called frälse in Swedish. This is often (mistakenly) said to be the formal foundation of the Swedish nobility.
