An eagle with two heads was one of the most famous political symbols in Europe for hundreds of years. It was the emblem of the Holy Roman Empire, and later of the Austrian and Russian Empires, and is still in use in Balkan countries and in the Greek Orthodox Church. The importance of the double eagle in so many places, as a royal and later as a national symbol as well as a focus of nationalism and loyalty, has kept this strange image prominent for centuries in the imagination, and in the collective unconscious, of people in many nations, and has figured in such incidents of sovereignty as coins, seals, flags, regalia and military uniforms, but also in civil arts and handicrafts in many media.
