1927–28 Panhellenic Championship

The 1927–28 Panhellenic Championship was the first season of the highest football league of Greece. It was held with the participation of 3 teams, the champions of the founding Associations of the HFF, Athens, Piraeus and Macedonia, in which Atromitos, Ethnikos Piraeus and Aris finished first, respectively. Aris eventually won the championship.

At the beginning of the season, the HFF expelled Olympiacos from the championship of Piraeus and consequently the Panhellenic Championship. They also forbade the other clubs from playing against them even in friendly matches. However, Panathinaikos, AEK Athens and Apollon Athens expected financial income from the tournaments they organized with the participation of Olympiacos. Thus, on 31 October, the HFF expelled the other clubs, as well. As a result, Panathinaikos, Olympiacos and AEK Athens formed an alliance called POK, from the initials of the words Podosferikós Ómilos Kéntrou (Central Football Group) or from a paraphrase of the initials of their names; "Panathinaikos"-"Olympiacos"-"Konstantinoupόleos". In February 1928, Apollon Athens joined the alliance, with the press calling it "POKA". The non-participation of these clubs weakened the championship, as the fans preferred the international friendlies of the strong clubs and the tournaments that have been established during the holidays since then. The devaluation of their competitions forced the HFF to revoke their dismissals in July 1928 and from the next season the clubs returned to their championships. The point system was: Win: 2 points - Draw: 1 point - Loss: 0 points.
