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 fogdeKristoffer Olsson and a few others labelled as "traitors" were captured. Local shops run by Germanmerchants were plundered, and the population taxed.
The rebels continued onwards through the region, gaining many new recruits. Within short they returned to Falun, and the locals pledged allegiance to Gustav Vasa and his cause. The rebellion continued until the Treaty of Malmö in 1524. A year earlier, in 1523, Vasa was crowned King of Sweden.
