AEK Athens Crest

In 1924, AEK adopted as Dikefalos Aetos, their emblem the image the double-headed eagle is featured in the flag of the Greek Orthodox Church, whose headquarters are in Constantinople, and served as Imperial emblem under the Palaiologos dynasty.
The emblem and colours (yellow & black) were chosen as a reminder of  lost homelands; they represent the club's historical ties to Constantinople.
