The Treaty of Roskilde

The Treaty of Roskilde, signed in 1658, ended the Second Northern War between Denmark-Norway and Sweden. Denmark-Norway had suffered military defeats and ceded significant territories to Sweden, including parts of modern-day Sweden and the northern region of Jutland. This treaty marked a shift in power, establishing Sweden as a dominant force in the region while weakening Denmark-Norway. The treaty was later revised in 1660, but it set the stage for further conflicts and territorial changes in Northern Europe during the 17th century.
