The club was founded in 2007 as AS Valea Ursului and competed in
Liga V –
Argeș County, the fifth tier of
Romanian football. After finishing 2nd in the 2010–11 season of the Center 1 Series, 1st place was claimed the following season, earning promotion to
Liga IV – Argeș County. The first two seasons in the fourth tier resulted in a 4th-place finish in the
2012–13 season and a 2nd-place finish in the
2013–14 season. In 2014, the team merged with AS Bascov to form Unirea Bascov. Led by coach Alin Lipa in the
2014–15 season, Unirea Bascov won the county championship but missed out on promotion to Liga III after a 2–4 aggregate defeat to
FC Aninoasa, the
champion of Dâmbovița County. A 2nd-place finish followed in the
2015–16 season. Under coach
Alin Chița, the county championship was won for the second time in the
2016–17 season. Unfortunately, promotion was missed again after a 1–4 aggregate loss to FC Avrig, the
champion of Sibiu County. Unirea Bascov finally secured promotion to
Liga III in the
2017–18 season. Coached by former
FC Argeș striker
Adrian Dulcea, the club achieved a historic treble by winning the Liga IV – Argeș County title, the promotion play-off to Liga III, and the
Romanian Cup county phase. In Liga III, Unirea Bascov finished 9th in the
2018–19 season and 7th in the
2019–20 season, which was interrupted on 9 March 2020 after 16 rounds due to the
COVID-19 pandemic. The club followed up with a 4th-place finish in the
2020–21 season and another 4th place in the
2021–22 season, both in the regular season and the series play-off. In the
2022–23 season, the team finished 6th in the regular season and 5th overall. In the summer of 2023, Adrian Dulcea left the team after six years to take on the role of coach for
Romania's U-18 national team. Marius Stoica was appointed as the new coach but was replaced in November by
Cosmin Năstăsie, who guided Unirea Bascov to a 7th-place finish in the regular season and 5th overall in the sixth series of the
2023–24 season. ==Honours==
