The club was established in 1948, under the name of Unirea Peciu and knew recent important progress in the Romanian football league system, especially after its promotion to Liga III in 2023.

[1] Despite the fact that Peciu Nou is the commune seat of the commune with the same name, football was much more successful in the village of Sânmartinu Sârbesc, where the local team Obilić Sânmartinu Sârbesc reached Divizia C during the 1990s and also with an important mark in the village of Diniaș, where local team Partizanul was a common presence at the level of Liga IV and Liga V. On the other hand, Unirea Peciu Nou had an important presence as well, but only at lower level, where in 1968 was one of the founding members of the Promotion Division (Liga V of today).

When everybody expected a setback, the white and greens surpassed themselves and during the next season obtained some excellent results, being crowned as "autumn champions" of the 9th series of the Liga III.
