Best Answer: The EU flag is the symbol not only of the European Union but also of Europe's unity and identity in a wider sense. The circle of gold stars represents solidarity and harmony between the peoples of Europe. The number of stars has nothing to do with the number of Member States. There are twelve stars because the number twelve is traditionally the symbol of perfection, completeness and unity. The flag therefore remains unchanged regardless of EU enlargements. The history of the flag goes back to 1955.
