Early years

Ionikos Nikaias' men's basketball club was founded in 1965, and it played its first game in 1966, during the 1966–67 season. Over the years, the club has featured Greek players such as: Panagiotis Giannakis, Fotis Katsikaris, Nikos Oikonomou, Vangelis Margaritis, Vassilis Kavvadas, and Marios Batis. Ionikos Nikaias played in the Greek 2nd Division for the first time, in the 1972–73 season. The club won the Greek 2nd Division first group in the 1974–75 season, and was thus promoted to the top-tier level Greek League, for the first time, for the 1975–76 season.

The club made 12 consecutive season appearances in the top-tier level Greek Basket League, during the 1970s and 1980s period, from the 1975–76 season, to the 1986–87 season. The club also competed in the 3rd-tier level European-wide competition, the FIBA Korać Cup, in both the 1979–80 and 1984–85 seasons.

On January 24, 1981, Ionikos Nikaias, led by a then 22-year-old Giannakis, played against Aris Thessaloniki, which was led at the time by Nikos Galis. Aris won in a tight game, by a score of 114–113. The game is memorable in the history of Greek pro club basketball, because in the game, Giannakis scored 73 points, and Galis scored 62 points,^[1] achieving the 2nd and 4th most points scored in a single game of the Greek League basketball championship.

On August 3, 1984, Ionikos Nikaias transferred its club star Panagiotis Giannakis, to the Greek club Aris Thessaloniki. Aris paid Ionikos Nikaias a transfer fee for his player rights, in the amount of 42 million Greek Drachmas,^[2] which was considered a huge amount of money for a transfer at that time. In order to complete the transfer, Giannakis also personally received a BMW car, a sporting goods store, and 8 million drachmas from Aris.
