Reception of Juliusz Mieroszewski’s political thought in the Polish Eastern politics after 1989

The aim of the article author was to show the political thought of Juliusz Mieroszewski not only in the perspective of its long cooperation with the Paris “Culture”, but also to prove the topicality of his concepts in contemporary politics. In the first part of the article the author focuses on the projects of Juliusz Machulski, connected to the direct neighbours of Poland – Lithuania, Belarus and Ukraine, at that time being a part of the Soviet Union. These were developed the furthest by the concept of ULB. The second part covers Mieroszewski’s ideas on settling the relations with Russia, with regard to their timely evolution, taking place on the pages of the Paris “Culture”. The third part of the article presents the author’s attempts to prove the existence of traces of Mieroszewski’s political thoughts in the contemporary Polish Eastern politics, both in the declarative and political plane
