The Swedish War of Liberation (1521-1523) was a conflict aimed at ending Danish rule over Sweden. It began when Gustav Vasa led a rebellion against the oppressive policies of the Kalmar Union, which united the crowns of Denmark, Norway, and Sweden. The war marked a significant turning point in Swedish history, leading to the establishment of an independent Swedish kingdom. The war concluded with the defeat of the Danish forces and the election of Gustav Vasa as the King of Sweden in 1523. This victory not only secured Sweden's independence but also laid the foundation for the rise of the Vasa dynasty, which would play a crucial role in shaping the future of the nation.
