It was founded in the 13th century,[2] by the Teutonic Order who erected a castle there and named it Labiau. Initially it was part of the State of the Teutonic Order. In 1454, King Casimir IV Jagiellon incorporated the region to the Kingdom of Poland upon the request of the anti-Teutonic Prussian Confederation.[9] After the subsequent Thirteen Years' War (1454–1466) the settlement became a part of Poland as a fief held by the Teutonic Knights[10] until 1525 and by Ducal Prussia afterwards. In this town, on November20, 1656, was signed the Treaty of Labiau. Lithuanian church services were held at the local church.[11] From the 18th century, it was part of the Kingdom of Prussia, and from 1871 it was also part of Germany, within which it was administratively located in the province of East Prussia. Labiau was a district seat in the administrative region of Königsberg. In 1885, Labiau had 4,744 inhabitants, almost all of whom were Lutherans.
Labiau was overrun by the SovietRed Army in 1945 near the end of World War II. After Germany's defeat in the war in 1945, the town was transferred to Soviet Russia and the following year it was renamed Polessk.[2] The German inhabitants were partly evacuated via the coast, or were subsequently expelled in accordance with the Potsdam Agreement and replaced with Soviet citizens.
