Historical and autobiographical approaches are combined with interviews to analyze the case of the Europa-Kontakt in pre-1989 Poland and West Germany within the framework of Europeanization. The international education encounters exemplify the tendencies to Europeanize, which emerged in both countries despite the Iron Curtain. The painful relationship between Poland and Germany is contrasted with the personal trust and cooperation between Polish and German exchange pioneers since the 1970s. Their pioneering work focused on multinational inclusion, participation, intercultural learning, gifted education, creativity, and building leadership skills. It merged German adaptation of the United States' HighScope model with philosophy of encounters typical of scouting tradition, Janusz Korczak's pedagogy, and Carl Rogers' humanistic psychology, preparing ground for the 1989-2004 European Union enlargement process.
