Polish émigrés were an important feature of the Cold War landscape in Europe, as were exiles from other Central European countries. In addition to opposing the Communist systems in their countries of origin, they tried to pursue independent policies in the West. Émigrés were active in political parties—including Christian Democratic, Socialist, and agrarian parties—but at the same time they attempted to create new forms, such as new political and social movements and transnational organizations. With active international agendas, they also worked to influence their own societies, both in the countries in which they had settled and in their countries of origin. This mixture of social and political dimensions was a specific phenomenon of Cold War intellectual history in Europe. The article draws on archival materials from Poland, Great Britain, France, Italy, and the United States and builds on concepts developed by scholars such as Maurice Duverger, Giovanni Sartori, V. O. Key, Jr., Yossi Shain, and Idesbald Goddeeris.
