In the 14th century, papal verdicts ordered the restoration of the town and region to Poland, however, the Teutonic Knights did not comply and continued to occupy it.[2] During the era of the Teutonic Knights, Graudenz had become a distinguished trade center in particular for textiles and agricultural products including grain.[citation needed] Around 1454, Graudenz had already reached about the same level of economic development as other towns in the western part of the State of the Teutonic Order, such as Danzig (Gdańsk), Elbing (Elbląg), Thorn (Toruń), Marienburg (Malbork), Kulm (Chełmno), Konitz (Chojnice), Neumark (Nowe Miasto Lubawskie) and Preußisch Stargard (Starogard Gdański).[citation needed]
