Having already been elected to the throne of the Polish–Lithuanian Commonwealth in 1587, Sigismund III of the House of Vasa is crowned King of Sweden, having succeeded his father John III of Sweden in 1592.

In 1594, Sigismund III of the House of Vasa was crowned King of Sweden, succeeding his father John III and uniting the crowns of Poland-Lithuania and Sweden.
Sigismund III, already King of the Polish–Lithuanian Commonwealth since 1587, ascended the Swedish throne in 1594 after his father's death. His coronation in Uppsala marked a rare personal union between two major European powers. As a Catholic monarch in a predominantly Protestant Sweden, his reign faced religious tensions and political opposition. The union fueled rivalries with his uncle Duke Charles and contributed to the outbreak of civil conflict. Sigismund's dual monarchy ambitions ultimately faltered, leading to his deposition from the Swedish throne in 1599. Nonetheless, his rule left a lasting impact on the political landscape of Northern Europe.
