AEK has a large fan base all over Greece. The majority of AEK supporters are refugees or have refugee descent from Constantinople, and people from the population exchange of the Minor Asia Catastrophe. Original 21 is the largest supporters group. The first attempt to organize AEK supporters was Gate 21 (formed in 1975), which took its name from the gate in the Nikos Goumas Stadium at Nea Filadelfia, where the most hardcore fans of the club gathered. AEK also has many supporters worldwide, most of them being Greek immigrants, in places like North America, UK, Australia, and Cyprus.
