Gustav Vasa's forces were a group of soldiers and supporters who played a crucial role in the Swedish War of Liberation during the early 16th century. Led by Gustav Vasa, they aimed to overthrow the Danish King Christian II and end the Kalmar Union, which united Denmark, Norway, and Sweden under a single monarch. Vasa's forces consisted of local peasants, nobles, and mercenaries who were motivated by a desire for independence and better governance. The campaign began in 1521 and saw Vasa's forces engage in various battles against the Danish troops. With strategic alliances and popular support, they gradually gained control over key regions in Sweden. By 1523, their efforts culminated in the establishment of Gustav Vasa as the King of Sweden, marking the beginning of a new era for the nation.
