I want to know the answer to the following question:
In what year was the territory of Warmia incorporated?
All the background I'm provided with is that "The former Polish Pomerelian lands beyond the Vistula River together with Malbork and Chełmno Land formed the Province of West Prussia with its capital at Marienwerder (Kwidzyn).". Is that enough to answer the question?
Answer: no
