Thyella Patras

The club was founded on 14 June 1930 and in the same year participated in the Third Amateur Division. The founding act was signed by Nikos Karelas and Vasilis Kotidis, with Giannis Fyteas serving as the club's first president.

By 1938, the team had reached the First Division and became a major contender, winning its first championship in 1951 and repeating the achievement in the following two years, 1952 and 1953. For many years, Thyella was the main rival of Panachaiki GE, with their matches becoming legendary and memorable in the local football scene.

In 1959, a merger was agreed with APS Olympiakos Patron, but it lasted only two years due to disagreements over the new club name. Thyella proposed "Thyellodis Olympiakos," while Olympiakos suggested "Olympiaki Thyella." During the 1959–60 season, the merged club played under the name "Olympiakos" and won the Patras championship, qualifying for the 1960 Greek football promotion play-offs for promotion to the Alpha Ethniki. In 1960–61, the club reverted to the name "Thyella Patron" and again qualified for the 1961 Greek football promotion play-offs, narrowly missing promotion to the top tier by finishing 4th behind A.O. Aigaleo, Panachaiki, and OFI, with whom they were tied at 37 points.

In 1963, Thyella became champions of Patras and earned promotion to the Second Division (Beta Ethniki), where they competed for four consecutive seasons, from 1963–64 through 1966–67.

In 1967, while still a Second Division team, Thyella was forcibly merged by law under the military junta regime and Sports Minister Konstantinos Aslanidis, along with six other clubs from Patras — APS Olympiakos, AS Iraklis Patron, APS Proodeftiki Patron, Apollon Patras, Patraikos Omilos Filathlon, and AO Achilleas Patras — to form the new club APS Patrai. Thyella opposed the merger, but authorities intervened and forcibly took the club's registry and charter. In response, club members hid the constitution, emblem, and seal in a metal box buried in a plot of land in the Eglykada area, where they remained hidden until the end of the dictatorship.

In 1969, the club was re-established based on the charter of its affiliated team "Elpis Eglykadas", and even before the fall of the junta in 1973, Thyella reclaimed its name, winning the Patras Championship and the local cup by defeating Achaiki 3–0 in the final. As champions, they participated in the 1973 Greek Amateur Football Promotion Championship, aiming for a return to the Second Division, but without success.

In the 1977–78, 1978–79, and 1981–82 seasons, the club played in the National Amateur Division, then the third tier of Greek football. From 1980 to 1983, Thyella reached four consecutive Achaia Cup finals but failed to win any of them. In the following years, the team moved between local leagues and the Fourth National Division, eventually winning the 9th Group of Delta Ethniki in the 2002–03 season and earning promotion to the professional Gamma Ethniki, where they played for five consecutive years (2003–04 to 2007–08).

In the 2008–09 season, they played in the 6th Group of Delta Ethniki but were relegated. They returned in the 2011–12 season but were again relegated to the Achaia regional league.

In 2019, Thyella won the Achaia Championship and returned to national competition in the 2019–20 season, marking their comeback to the fourth tier after a seven-year absence. For the first time, they competed in the restructured Gamma Ethniki Amateur Division.

From the 2021–22 season to 2024–25, the club competed in the Achaia First Division. In 2025, they won the championship and took part in the 2025 Greek Amateur Promotion Championship, securing promotion back to the national divisions after a four-year absence.
