Armistice of Stuhmsdorf

The Armistice of Stuhmsdorf, signed on September 12, 1635, was a treaty between Poland and Sweden that ended their conflict during the Thirty Years' War. This armistice was largely a result of Sweden's involvement in the war and its desire to focus on the Holy Roman Empire.1

Under the terms of the armistice, Poland ceded the duchy of Pomerania to Sweden for a period of 12 years. Sweden also agreed to withdraw its troops from Polish territory. This agreement allowed Sweden to concentrate its military efforts against the Holy Roman Empire, while Poland was able to focus on its internal affairs and other conflicts. The armistice did not resolve the underlying issues between the two powers and was a temporary measure rather than a lasting peace.1
