Within so called Royal Prussia, only Lubavia and Pomesania were actual Prussian lands.

==========

Before the Prussian Crusade (which started in year 1218) there were those 12 realms. After the Thirteen Years' War, most of Lubavia and Pomesania became parts of Polish Royal Prussia (the remaining parts became portions of Oberland - Upper Prussia - western part of Ducal Prussia). Lubavia was incorporated to Chełmno Voivodeship of Royal Prussia, and Pomesania (a less historical Polish name for this region is Powiśle, or "Land beyond the Vistula") to Malbork Voivodeship. Most of Pogesania became part of Oberland in Ducal Prussia. After the crusade Bartia was partially incorporated into Warmia (Ermland) within its new borders, and partially remained a separate region. Galindia and Sasna became known as Masuria after they were colonized by Polish settlers (most of whom came from Masovia, hence the name transfer). Some parts of Galindia were also absorbed by Masovia. Nadrovia and Skalovia became known as Lithuania Minor (or Prussian Lithuania) after they were colonized by Lithuanian settlers. Later part of Skalovia became known as Memelland (this part is now in Lithuania). Sudovia (also known as Yotvingia or Suwalszczyzna in Polish) was in Poland-Lithuania and later became part of the Duchy of Warsaw and of Congress Kingdom of Poland.
