The aim of the article is to discuss the attitude of Polish republican circles to the issue of cooperation between countries in EastCentral Europe. The articles published in the “Rzeczy Wspólne” and “Nowa Konfederacja” magazines, which were published in 2010-2017, have been analyzed. The ideas of region integration have deep roots in Polish political thought. Their origins can be seen in the tradition of the old Polish-Lithuanian Commonwealth and the concepts of Marshal Piłsudski. The ineffectiveness of the activities of the politicians of the Third Polish Republic in this field became the reason for criticism in republican articles. An important role in the analyzed visions was played by countries located outside the EU - Belarus and Ukraine, for geopolitical reasons considered as desirable allies. The slogan of deepening the integration of the Visegrad Group and strengthening the Eastern Partnership initiative was also popular. However, this cooperation was to take place between fully sovereign states.
