The Livonian War (1558–1583) was a pivotal conflict in the Baltic region, shaping Sweden's role as an emerging power in Northern Europe. The war, fought primarily for control of Old Livonia (present-day Estonia and Latvia), pitted Russia against a coalition of powers, including Sweden, Denmark, and Poland-Lithuania. The war unfolded as part of broader geopolitical competition, with Sweden seeking to expand its influence in the Baltic.

Sweden's involvement began in 1561 when it established control over northern Livonia, forming the Duchy of Estonia. This marked a key step in Sweden's efforts to secure access to Baltic trade, especially as Denmark and Russia competed for dominance in the region. During the early stages of the war, Russia, under Ivan IV, achieved significant victories, but by the 1570s, Sweden, alongside Poland-Lithuania, began to push back.
Sweden’s turning point came under King John III, whose military campaigns, alongside Polish forces led by King Stephen Báthory, helped shift the momentum against Russia. In 1581, Sweden captured the strategic city of Narva, solidifying its hold on the region. The conflict ended with the Truce of Plussa in 1583, which allowed Sweden to retain control of northern Livonia and parts of Ingria.
The Livonian War was significant for Sweden as it marked the beginning of its rise as a major Baltic power. By gaining territory in Livonia, Sweden not only expanded its influence but also secured key positions that would be crucial in future conflicts. This territorial gain laid the groundwork for Sweden's later dominance in the Baltic during the 17th century, shaping the region’s political and economic landscape.
