Włocławek received its city rights in 1255. During the 14th and 15th centuries, the city was destroyed and captured several times by the Teutonic Knights and renamed it Leslau.[citation needed] The Treaty of Thorn, signed in 1411, resulted in short-lived peace for the city, however, it prospered from its involvement in the ransoming of the captured Teutonic Knights which was payable in three instalments and proved to be a hardship on the Prussian faction. Włocławek was located within the Brześć Kujawski Voivodeship of the Greater Poland Province. There is a possibility that Nicolaus Copernicus, the later renowned astronomer, may have attended the local cathedral school in the late 15th century.[4]
