AC Omonia participant of 1965–66 Cypriot First Division
Beginnings in the Cypriot First Division (1953–1969)
After joining the Cypriot First Division in 1953, Omonia only placed seventh out of nine teams in the 1953–54 season, barely avoiding relegation. During that decade, the club's best placing came during the 1956–57 season when the club finished in the third position.
The team would make its closest push for the title during the 1959–60 season after finishing second, one point behind Anorthosis Famagusta. The following year, after seven seasons in the First Division, the club would win its first title in 1960–61 season. Omonia, in that season, would score 91 goals in 24 matches on their way to their first ever Cyprus First Division title. Omonia won their second title during the 1965–66 season.Honours
