A number of symbols of Europe have emerged since antiquity. In present day, each of these may either apply to the continent as a whole, European unity or specifically to the European Union (EU). Several symbols were introduced in the 1950s and 1960s by the Council of Europe (CoE), and while these symbols were intended to represent Europe as a whole, they are often seen as referring to the EU exclusively after their adoption by that organisation. In addition to those of Pan-European identity, the EU has created additional symbols for itself through its integration.
