Four major rebellions originated in Dalarna. In 1434, miners rose against the officers of Eric of Pomerania under Engelbrekt Engelbrektsson. From 1519 to 1523, the miners backed Gustav Vasa's revolt against the Kalmar Union. From 1524 to 1533, three uprisings against Gustav's autocratic and reformist rule were brutally suppressed. In 1743, the Dalecarlian Rebellion against the Hats became the last major peasants' uprising in Swedish history.
