The aim of this paper, based on an extensive archival search, will be to discuss the beginnings of Polish research on early medieval Western Pomerania after World War II. A special place will be given to the presentation of the continuation of research topics already undertaken during the interwar period in the academic centre in Poznan and their influence on research directions after the war. This continuation was often the result of a kind of genealogy of historical and archaeological schools and the succession of the masters' interests despite the changing political situation. The second plot that will be given increased emphasis will be the portrayal of the Poznan academic centre as a promoter of research on Pomerania both before and after 1945, whose graduates largely colonised many scientific institutions in the western lands, especially in Pomerania.
