It was formerly part of Prussia. It was by 1242 sectioned into four dioceses by papal legate William of Modena. Under the archbishop of Riga in Livonia, the four Prussian lands were called Culmer Land, Pomesania, Warmia and Samland.
The bishopric of Warmia in Prussia later became a separate exempt bishopric. The eastern part of Prussia went from rule by the Teutonic Knights to being ruled by the Hohenzollern family, starting with Albrecht of Brandenburg-Ansbach and Prussia or Albert of Prussia, also referred to as Albert I of Prussia or Albert I Brandenburg. This part was later called East Prussia.
Warmia's most famous citizens were the family members of Lucas Watzenrode or Watzelrode, who was bishop of Warmia and who raised and educated his nephew Nicolaus Copernicus and his brother, when their father died. Nicolaus was born in the Prussian Culmer Land in the Hanseatic League city of Torun. He studied in Italy at the German University and in Krakow, also a Hanseatic city at that time. Later Nicolaus secured income as Majordomo in Frauenburg. As a Prussian representative he worked on coin money reform . His main occupation was as a doctor and only in his spare time did he work on his other project for which he later became world famous.
