The Battle of Falun (Swedish: Slaget om Falun) was the first battle of the Swedish War of Liberation that took place in Falun, Sweden on February 5, 1521. Swedish rebels under Gustav Vasa, who had just days earlier been proclaimed leader of the Dalecarlians against the Danes, raided Falun. The rebels, consisting of a few hundred poorly armed peasants and some noble officers, took the Danish forces in the town completely by surprise. The local fogde Kristoffer Olsson and a few others labelled as "traitors" were captured. Local shops run by German merchants were plundered, and the population taxed.
