This paper argues that the five East-Central European states have a common historical trajectory as a region, in which Poland fits to both the conceptual framework and to the average data, being on some issues somewhat better, on some other issues somewhat worse than the ECE average. Therefore, the paper denies the thesis of Poland’s „singularity” that presupposes the special situation of Poland, very different from the ECE region based on a particular success story in the last Quarter-Century and/or during the EU membership. It means also that the latest developments in Poland can push the country to more divergence from the EU mainstream as it has been the case in the 2010s with Hungary.
