Establishment
In 1927/28, the EEA (Committee of Professional Sports or in Greek, Επιτροπή Επαγγελματικού Αθλητισμού) was preparing to host its first football championship in Greece with the participation of the League teams of the three founding football associations: E.P.S. Athens, E.P.S. Piraeus and E.P.S. Macedonia. At the start of the season and before the games had begun, EEA decided to punish Olympiacos FC for formal reasons and ordered the other unions not to play them in any official or friendly matches. Panathinaikos and AEK, however, did not obey and followed Olympiacos in organizing friendly matches between the three teams. Essentially, this was the outbreak of a dispute that was brewing between these three clubs and the administration of the league for the control of the latter.
After this development, the EEA dropped all three clubs on 31 October 1927 and proceeded to organize the league without them. The teams that took their place were Atromitos from Athens, Ethnikos from Piraeus and Aris from Thessaloniki.
