After 1945 the eastern part of Pomerania, according to an agreement signed in Potsdam in 1945 by United Kingdom, United States of America and Soviet Union, was given under the administration of Poland. There was never any peace treaty, but Willy Brandt and Helmut Kohl signed bilateral agreements with Poland according to which Germany recognizes the current factual reality of the Oder/Neisse? Line.
The western part of Pomerania remained a part of the German Bundesland Mecklenburg-Vorpommern.
