V4, or the Visegrád Group, is a cultural and political alliance of four Central European countries: Poland, Hungary, Czech Republic, and Slovakia. Established in 1991, the group aims to foster cooperation in various areas, including economic development, security, and cultural exchange. The V4 countries collaborate on regional issues and share common interests within the European Union. They often coordinate their positions on matters such as migration, energy security, and defense, enhancing their influence in European affairs while promoting mutual support among member states.
