The original club (1922–2006) History of the professional football started in
Odorheiu Secuiesc in 1922, when it was founded the first team of the city,
Textila. For nearly fifteen years, the club competed in the district and regional championships without achieving any notable results, but that was about to change in the summer of 1968 when, after a
strong campaign, Lemnarul Odorheiu Secuiesc earned its first-ever promotion to
Divizia C by winning Series II of the
Mureș Regional Championship This beautiful dream lasted
only one season, as Textila proved unprepared for the challenges of this level, finishing 17th out of 18 teams under the leadership of
Tiberiu Bone. In the summer of 1974, after the relegation from
Divizia B, the leadership of the club decided to bring some fresh air inside the team and one of the measures was to change its name, from Textila Odorheiu Secuiesc to
Progresul Odorheiu Secuiesc. After four seasons in which at its best the team was ranked 3rd, Progresul finished again second, two times in a row, at the end of the
1980–81 and
1981–82 seasons, first time behind ICIM Brașov, then right after
Precizia Săcele. In these conditions when the team seemed to force the promotion to the second tier again, relegated unexpectedly in
1983, after finishing 15th of 16. Interestingly, it's the same year in which the other team from
Harghita County,
Tractorul Miercurea Ciuc also relegated. Progresul promoted back after
only one year of absence and for the next seven years imposed itself as a strong opponent, being ranked generally in top five of its series, two times even finishing in second place (
1987–88 and
1988–89). In the summer of 1991, the club changed its name again, this time from Progresul Odorheiu Secuiesc to
Harghita Odorheiu Secuiesc.
Odorheienii continued their
Divizia C spell but at its best, the team was ranked third. After two weak seasons, 1996–97 – 15th and 1997–98 – 18th, the team has gone through some administrative changes and in the summer of 1998 changed its name from Harghita Odorheiu Secuiesc to
Budvar Odorheiu Secuiesc. In six years as "Budvar" the team finished only one time in top 10 (2000–01 – 5th), the mediocre results culminating in a relegation to
Divizia D at the end of the 2003–04 season, after exactly 20 years spent in the third tier. During the next two years the football from the city struggled to survive, in 2006, the team of SC Roseal SA company, CS Roseal Odorheiu Secuiesc promoted to
Liga III, but can't survive at this level and after only one season relegated back.
Refoundation and recent years (2006–present) On 12 December 2006, at the initiative of some local football managers and supporters, a new entity, named
AFC Odorheiu Secuiesc, was founded to be the successor of the old club, known over time as
Textila,
Progresul,
Harghita or
Budvar. The founding members of the football club, in its current form, were: Csaba Albert, Lajos Balázs, Attila Berkeczi, Csaba Dénes and Domokos Jankó. After promotion the black and orange team obtained the following rankings: 12th (
2015–16), 12th (
2016–17) and 11th (
2017–18). ==Grounds==
