Magnus I of Sweden
From Wikipedia, the free encyclopedia.

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, which possibly was his second name.

With the Alsnö stadga (Decree of Alsnö) about 1279, Magnus gave anyone who undertook to provide the Crown with a mounted warrior (knight) and a warhorse, the 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, though it certainly was a step in the evolution towards hereditary class of nobles enjoying privileges).

Second son of Birger Jarl (Earl Birger Magnusson) and Ingeborg Eriksdotter of Sweden, herself the youngest sister of childless Eric XI of Sweden and youngest daughter of Eric X of Sweden and Richeza of Denmark. His father designated Magnus as his successor in powers of the earl of the realm, henceforward titled Duke. The elder brother, Valdemar I of Sweden having become the king in succession of their maternal uncle.

In 1275, Magnus started a rebellion against his brother with Danish help, and ousted him from the throne. Instead, Magnus was elected King at Mora. Magnus Ladulås married 1276 as his second wife Helvig of Holstein, daughter of Gerhard I of Holstein (through her mother Elisabeth of Mecklenburg, she was descendant of Christina, the putative daughter of Sverker II of Sweden, and of Ulvhild of Saxony, a descendant of Astrid Olofsdotter, queen of Norway and daughter of Olof I of Sweden). Helvig later acted as Queen Regent (probably 1290-1302 and) 1320-1327. A papal annullment of Magnus' first marriage and a dispensation for his second (necessary because of consanguinuity) were issued ten years later, in 1286.
