It was February 3rd, 1908 when the track & field athlete of Panellinios Sports Club, Giorgos Kalafatis took the initiative to found a new Club that was to become the most glorified football team of Greece.
Initially the abbreviation of the team’s name was P.O.A (Football Club of Athens) and among the founding members, apart from G. Kalafatis, was also his brother Alexandros, and Mr. Doukakis, Bouboulis, Chrisis, Granitsas, Mantzakos, Papageorgiou, Gaetas, Demertzis, Stavropoulos, Paschos, Misakian, Reppas, Sapounias and Garoufalias.
In the beginning of 1910, the Club was renamed to P.P.O. (Panhellenic Football Club) and continued to be active and to gain a large number of sports fans. After the end of World War I, the football activity restarts with PPO having adopted the green colour and the emblem of the shamrock, which was designed by the director and member of Panathinaikos, Georgios Hatzopoulos. The shamrock was "brought" into Panathinaikos, by the athlete and later General Secretary of the Club, Michalis Papazoglou, which he bore in the team Chalcedona of Constantinople (Istanbul) where he had competed. In 1919 the Union of Football Clubs of Athens and Piraeus organised the first post-war championship in which Panathinaikos was pronounced champion.
The final name, Panathinaikos Athletikos Omilos (Panathinaikos Atletic Club) was resolute in 1922 and was made official in the General Assembly of the 15th of March, 1924. On the 26th of April, 1925 Panathinaikos played its first international game against the Yugoslavian team “Vittoria Zagreb”, in which the final score was 1-1. In 1926 he beat Austrian team Kaufenberg by 1-0. The same year he also played the first match in Thessalonica against AEK Thessalonikis (that later became PAOK), which he won by 2-0.
One of the most important personalities in the history of Panathinaikos was Apostolos Nikolaidis, a phenomenal athlete in football, track & field, basketball and volleyball. He took part in the Olympic Games of Antwerp in 1920 as footballer and as a track & field athlete. He was the president of the Hellenic Amateur Athletic Association for 20 years. He had been a member of the Board of Directors of Panathinaikos for a number of years and in 1974 he became the president of the club. He is considered to be a symbol of Panathinaikos and for this reason the football field of Alexandras Avenue is named after him.
In 1928 a non-national was hired as head coach; the Hungarian Milko Forner. For first time the team is organised by way of a programme and it easily wins the Championship of Athens, with 8 victories in 8 matchups, in which it scores 41 goals and concedes only 3.
