Signs of settlement dating back to the Roman Empire era have been found. In the early Middle Ages, a fortified settlement of the Prussian people existed at the site, conquered by the Teutonic Knights in 1236. City rights were granted to the settlement in 1416.
In 1466 the town with other western Prussian territory passed to the crown of Poland as part of Royal Prussia. As part of Poland, the town functioned as a seat of Sztum powiat in Malbork Voivodeship (1466-1772) and a place to hold local court sessions. In 1635 the Treaty of Stuhmsdorf was signed in the village of Stuhmsdorf (now Sztumska Wies, just south of the city of Sztum).
According to the Treaty of Versailles, after World War I the inhabitants of the town and its district were asked whether they want to remain in Germany or join the new Second Polish Republic in the East Prussian plebiscite of 1920. Ultimately, in the district of Stuhm 19,984 votes were counted to remain in Germany and 4,904 votes for Poland Based on that result Stuhm was included in the Regierungsbezirk Marienwerder within East Prussia.
After World War II the area was placed under Polish administration by the Potsdam Agreement under territorial changes demanded by the Soviet Union. Germans fled or were expelled and replaced with Poles expelled from the Polish areas annexed by the Soviet Union or forced to settle in the area through Operation Vistula in 1947.
