Nils Ravaldsson (died 1505) was a leader of the Alvsson's rebellion.
He was the leader of the rebellion after Knut Alvsson was murdered.
Ravaldsson died in exile at a farm in Västergötland in Sweden the next year.
Ravaldsson escaped the carnage only by jumping from the top of the castle tower, and into a pile of snow.
[1] Ravaldsson died in exile at a farm in Västergötland the next year, probably from the wounds he received during the attack.
