The creation of a championship in the form of a single permanent national category rather than the way they have been held until then with the participation of the teams selected by the local competitions was a requirement of both the State and UEFA. The first wished to establish a fixed number of matches every Sunday in Greece to stimulate interest in PRO-PO while UEFA wished to nominate national champions with strict criteria and through joint events for all states. The Hellenic Football Federation (HFF) was obliged to proceed to the abolition of the competitions of the Football Clubs Associations Panathinaikos (EPS) of Greece as qualifying stages for the Pan-Hellenic Championship. The first place was taken by Alpha Ethniki, a single category with clubs from all over the Greek territory and a stable participation, with the exception of those who would be relegated at the end of the season. The initial design provided for a number of teams well above the 10th of the 1958–59 Pan-Hellenic Championship and in particular 18 which, as the expanded category program would cover almost all the particular available dates of the year, would no longer participate in its local competitions their EPSs.
The Greek football clubs have not won any major UEFA competition yet; the only club that have reached a final so far is Panathinaikos, who were European Cup runners-up in 1970–71, while they have also reached the semifinals on two occasions. Olympiacos and AEK Athens have made it to the quarterfinals in the top European clubs’ competition, while these three clubs have reached the quarterfinals in the other major UEFA competitions as well, with AEK Athens’ best performance being a semifinal appearance in the UEFA Cup. The Greek Basket League is the top professional basketball league in Greece and one of the strongest in Europe, while several Greek clubs have won major European titles. AEK Athens was the first-ever Greek team, not only to reach an European Cup Final, but also to win an European title. On April 4, 1968, AEK Athens defeated Slavia Prague by a score of 89-82, in Athens before 80, 000 spectators.
The official national championship was held for a first time in the season 1927–28. Super League Greece is now the highest professional league in the Greek football league system. It is currently ranked 12th in the UEFA coefficient, while it was placed among the top ten strongest leagues in Europe from 1996 to 2006, with its peak being the 6th place in 2002 and 2003. The Greek Football Cup has been the main domestic cup competition, inaugurated in season 1931–32. Both competitions have been dominated by Olympiacos, which is the most successful football club in Greece, followed by the other two big Greek football clubs Panathinaikos and AEK Athens.
