Beginnings (1923–1956)

After being founded in 1923, Ruspina Sports was officially renamed US Monastir on 13 June 1942, the date of publication in the official journal of the decree of her creation.

At the end of the 1930s, Ruspina Sports experienced innumerable financial difficulties and a series of disgraces within the general public which, far from being insensitive to the misdeeds of colonialism, resolutely committed against it by creating teams of neighborhoods. Just as Ruspina Sports is in decline, voices are being raised to unify the other teams and create a kind of unique selection. On 13 June 1942, the decree creating USM was signed and the new association inherited Ruspina Sports' credit balance, i.e. 5,395 Tunisian francs.

If the end of the war coincided with a renewed interest and enthusiasm among the Monastirians for football, the USM has more than one hundred players, half of whom play in the senior team and the second half in the junior categories, the following years will be more difficult.

After independence (1956–1979)

With the independence of Tunisia, USM knew a turning point. In the field, USM did not win any titles either in the Tunisian Cup or in the league. Each time, the USM returned to the charge and, after its successive relegations, goes back to the first division. It is during the 1961–1962 season that the USM reached for the first time in the national division after having spent two seasons in the third division (1957-1958 and 1958–1959) and one season (1959-1960) in the honor division.

Results between rise and fall (1980–2019)

The 1980s were a turning point for the club, which became semi-professional and allowed the team to remain in the national division for fourteen consecutive years. During the same season, USM qualified for the quarter-finals of the Tunisian Cup but lost in Monastir against the Club African (1-0) during the overtime session. With eight wins, eight losses and ten draws, USM occupied a comfortable fifth place.

This situation does not last and the 1993–1994 season promised to be very difficult on all fronts and more particularly material. Four coaches followed one another to help a team in crisis since it suffered from several shortcomings. During the 1994–1995 season, the team found itself relegated to the third division according to the new organization of the Tunisian Football Federation. During the 1995–1996 season, Habib Allègue took the reins of the team which managed to win and advance to the honor division (southern pool) before returning to League I two seasons later and maintaining his position. In July 2006, Néji Stambouli succeeded Zouhair Chaouch, in place for six years, at the head of the club.

On 3 May 2009, after a victory against Esperance Sportif de Tunis at Stade El Menzah, on the score of three goals to two, the club qualified for the first Tunisian Cup final in its history: it opposed CS Sfaxien on May 24 at the November 7 stadium in Radès, and ends with a score of 1 to 0 for the Sfaxiens with the presence of president Zine El Abidine Ben Ali.

At the end of the 2009–2010 season, the club was relegated to Ligue II.

However, the team re-promoted to the first division after one season, and its ranking ranged between fifth and tenth in the following years until it relegated in 2015 and the team spent two seasons in the second division before rising again in 2017.

After that, the teams presented respectable levels after the assignment of coach Skandar Kasri and Lassaad Dridi to finish the ranking in 2019 in seventh place.

Golden generation (2019–)

And at the beginning of the 2019 season, a contract was signed with Lassaad Chabbi. The 2019–2020 season the team managed to take third place in the national league, which enabled it to participate in a continental competition for the first time in its history, namely the 2020–21 CAF Confederation Cup.

As for the Tunisian Cup (named the Habib Bourguiba Cup this season, on the occasion of the 20th anniversary of his death), the team managed to win it for the first time in its history, after beating Espérance Tunis in the final 2–0.

After Chabbi resigned from coaching the team, Afouène Gharbi, who finished the season in tenth place, was appointed. The team then contracted with Mourad Okbi, who succeeded in winning the team's second title in its history by obtaining the Tunisian Super Cup.
