The author joins in the discussion on the problem of the community, which in sociology, especially the American one, was first undertaken by the Germans, and dates back to the turn of 19th and 20th centuries and is associated with the name of Georg Simmel. In the mid-20th century the idea was back in the centre of interest, when Europe witnessed great waves of migrations after the second world war. The victims of the mass migration were, among others, the Germans removed from the territories given to Poland after the war as a compensation for its lost eastern regions. The migration went in several stages. It is worth mentioning that parts of the population were leaving their original place of living at different times and of their own will. Therefore there was a specific dualism in the status of the people forced to migration who ended up in Germany after 1945. As a result, there is a sociological difference between the people forced to migration and the ones who decided to do it of their own will. The processes of adaptation to a new life in Germany of the two groups were different, and so were the attitudes to Poland and the Poles. It is still a unexplored research problem in the history of the Polish sociology.
