The role of the European Union (EU) in member states' governance includes promoting economic integration, political stability, and shared standards across various policy areas. The EU establishes regulations and directives that member states must implement, affecting trade, environmental policies, and social issues. Additionally, the EU facilitates cooperation on security and foreign policy matters. Through its various institutions, the EU aims to align member states' interests while preserving national sovereignty. However, the balance between EU authority and member autonomy often drives contentious political debates within and among states.
