The parent athletic sports club, Ilysiakos Athlitikos Omilos (
Greek: Ηλυσιακός Αθλητικός Όμιλος), was founded in 1927. The basketball team of Ilysiakos was established in 1968. In the 1986–87 season, Ilysiakos participated for the first time in the top
Greek Basket League, and stayed there for two straight seasons. Following the 1987–88 season, the team got
relegated to the
Greek 2nd Division. From 1988 to 2003, the club was competing in the Greek second and third divisions. However, the club had its biggest success with its participation in the final four of the
Greek Cup in 1995, where the team finished in 4th place. In the year 2003, the club got
promoted to the first division again, but was once again relegated to the second division after the 2003–04 season. The club's second return to the first division, in the
2009–10 season, was much more successful, as Ilysiakos played in the top division for 5 consecutive seasons. During that time, players like
Vonteego Cummings,
Brent Petway,
Terrell Stoglin, and
Aloysius Anagonye played with the club. In this same era of the club,

Greek national team, and won several titles in his playing career: 2
Greek Cups (2000, 2001), the
FIBA Saporta Cup (
2000), and the
Greek League championship (2002), became the
captain of the team. In this same time,
Panagiotis Kafkis and
Georgios Apostolidis, who also represented Greece, were also members of the team. ==Arena==
