Following World War II, the borders of Pomerania underwent a major transformation that effectively divided the historic region.1

Under the terms established by the Allied powers, the vast majority of central and eastern Pomerania was transferred to Poland in 1945. This new boundary was defined by the Oder-Neisse Line, which placed territories east of the Oder River under Polish administrative control. As part of this geopolitical shift, the German population residing in these central and eastern areas was expelled westward.12

In contrast, the westernmost section of Pomerania remained in Germany. This area was incorporated into the German Democratic Republic (East Germany) and was eventually combined with the historic region of Mecklenburg to form the modern German state of Mecklenburg–West Pomerania.13
