The creation of the European Union (EU) is significant in European politics, representing a commitment to economic and political integration among member states. Established in the aftermath of World War II, the EU aimed to foster stability, promote cooperation, and prevent future conflicts through shared governance and trade. It facilitates the free movement of goods, people, and services, contributing to economic growth and unity. The EU also plays a critical role in addressing transnational issues, such as environmental policy and migration, shaping the geopolitical landscape in Europe.
