The Visegrad Four, an alliance of four countries - the Czech Republic, Slovakia, Poland and Hungary, celebrated 30 years since its creation this year. The group's cooperation has changed several times over the 30 years, with major changes within the V4 Group at the beginning of 2015 when the migration crisis erupted in Europe and continuing now as Poland and Hungary move away from the values of liberal democracy. The states are now dealing with a coronavirus pandemic as well as other crises, such as the Turów mine dispute. These and other crises may have had a negative impact on the functioning of the V4 Group. What is the effectiveness of the alliance? What issues have the representatives of each state addressed in recent years? The cooperation has been established to promote European integration and now the countries faced issues within the European Union. And how do they support each other in their respective disputes? The proposed paper will answer these questions and discuss the role of this group in the Eastern European region through an extensive analysis over the last few years.
