Teresa Willenborg’s book is devoted to analysis of the situation of the German population of former German territories which were granted to Poland in 1945 basing on diplomatic conferences of great powers: USA, Great Britain and the Soviet Union. Willenborg focuses on experiences of Germans who decided to remain in their hometowns and villages. The subject of her interest is here mainly a term of becoming ‘foreign’ and ‘solitare’ in their own homeland after 1945. Thanks to usage of various Polish and German sources the author managed to stress the fact, that the history of post-war expulsions and national minorities often requires a transnational approach.
