The shift of the name Kashubia towards the east is a commonly known historical fact, but the significance of this change has not been properly explained. I believe that the problem remains unsolved due to the limitations of the naturalistic or objectivist paradigm. Therefore, I propose looking for the solution to the problem within the framework of the anti-naturalistic paradigm, which means giving Kashubia the status of a social construct. Using anthropological findings, I set out to prove that the location of Kashubia in the geographical space, as well as its conceptualisation, had a social and cultural basis; specifically that it was conditioned by the German point of view. As such, the changes of Kashubia’s location on the map were a reflection of the dynamics of identity processes in the territory of broadly defined Pomerania and Mecklenburg.
