The official city webpage states that between the 7th and 6th century BC the area of the city was the site of a village and that the area of Western Pomerania was settled by Slavs in the 6th-8th centuries; when the city rights were established the Złocieniec webpage informs that it's highly probable that among German inhabitants of the city were also Slavs from Budów i Strzebłów-villages that were disbanded. City laws were established by the brothers von Wedel on 13 December 1333. In 1668 the city was almost completely destroyed by a fire. During the era of Nazi Germany the Ordensburg Krössinsee was built near the town in 1934. The SA attacked the Jewish population here during Kristallnacht, later, during the Second World War a forced labour camp was established near the city, from which 31 Poles managed to escape. After World War II the city was handed over to Poland by the Allies, with Poles being transferred from the East while Germans were expelled to the west.
