The Dacke War () was a peasant uprising led by Nils Dacke in Småland, Sweden, in 1542 against the rule of Gustav Vasa. Dacke and his followers were dissatisfied with the heavy tax burden, the introduction of Lutheranism, and the confiscation of Church property (the confiscation and taxes were introduced to pay for the Swedish War of Liberation that had brought Gustav Vasa to power). In 1543 the uprising was defeated, and Nils Dacke was killed. Background Nils Dacke and his peasants were dissatisfied with the policies of the Swedish king Gustav Vasa. In his effort to modernize Sweden and gain more power, the king had instituted a more efficient system for tax collection. The heavy tax burden angered many peasants. Gustav Vasa had also broken relations with Rome and promoted Lutheranism instead of Catholicism in order to confiscate the property of the church (including land), effected by the laws of the Reduction of Gustav I of Sweden.

Gustav Vasa responded by sending a military force led by his own father-in-law Gustav Olofsson Stenbock the Younger. He was defeated by Dacke's constantly growing army of peasants. Other attempts to defeat Dacke militarily also failed. Dacke and his army reached as far north as Mjölby at the fringes of the Östergötland plains and enjoyed widespread support around Sommen and Ydre. Local aristocrat Måns Johansson Natt och Dag sided with the king despite having a troublesome relation to him. He was put in charge of an army to suppress the rebellion. Next, the Swedish government stopped all supplies of provisions and other necessities to the region. This weakened the rebellion considerably. Defaming propaganda about Dacke was also spread by the government, labeling him a traitor and a heretic. In March 1543 Gustav Vasa ordered his army of Swedish
