The exhibition "Polenaktion" presented at the Emanuel Ringelblum Jewish Historical Institute recalls the October 1938 events. The history of Polenaktion is seen there through the prism of individual victims' biographies, mainly the particular stories of six Jewish families expelled from Berlin in 1938, following the 26th of October order of  Reinhard Heydrich, chief of the Reich main security office, specifying that all Polish Jews would be immediately expelled from Germany. They were given a deportation order and were taken to the Polish-German border. About 17,000 Jewish citizens of Poland found themselves on border stations of Zbąszyń, Bytom, near Chojnice and Wschowa. In response, Jewish aid organization JOINT quickly organized help. Shelters were set up in Łódź, Warsaw, Będzin, Katowice, Bielsko-Biała, Kalisz and other Polish cities. Emanuel Ringelblum, one of the JOINT coordinators was particularly instrumental in encouraging the refugees to write about the details of their deportation, which he considered an „unprecedented event in the Jewish history”. The exhibition consists of three parts in chronological order: "Life in Berlin before 1938”, "Deportations in October 1938”, "The history of persecution and rescue”.
