The Polish-Slovak border: between European integration and local political conditions

The Polish-Slovak border is an example of a dynamically changing political and social space in Central Europe. Its evolution – from a line of dispute and national delimitation in the 20th century, through its opening within the Schengen area, to contemporary challenges of security and cross-border cooperation – reveals the paradoxes of European integration. On the one hand, the border is undergoing a process of "debarrierization": it is becoming a place of everyday mobility for residents, local government cooperation, and the functioning of Euroregions. On the other hand, it remains a space where institutional differences, migration challenges, transnational crime threats, and environmental problems are revealed. The analysis shows that local conditions—strong social ties, borderland identity, institutional asymmetries—shape border practices as strongly as EU regulations. The thesis of the article is that the Polish-Slovak border is neither exclusively a barrier nor a bridge: it is an ambivalent membrane which, depending on the context, serves to open or close space. Studying it allows for a better understanding of the contem-porary tensions between integration and security in the European Union.
