The analyis of the impact of European integration on ethnoregionalist parties in Europe has up until now received very little scholarly attention in Poland. For this reason the main aim of the presented paper is the analysis of the role of ethnoregionalist parties in the political decision-making process at the level of the region, the state and of the unified Europe. The most important question is weather this group of non-state-wide parties should be seen like the opportunity or menace for the unified Europe.
