The European Union flag features a blue background with a circle of twelve gold stars. The stars are arranged in a circle, symbolizing unity and harmony among the member countries. The number of stars remains constant at twelve, representing perfection and completeness, rather than the number of member states. Adopted in 1986, the flag is used by the European Union and its institutions. It serves as a symbol of European integration and cooperation, reflecting the values of democracy and human rights. The flag is displayed at official buildings and events related to the EU.
