Early years (1933–1965) Rahmatganj Muslim Friends Society was founded in January 1933 in
Old Dhaka, during the
British regime. The club's founder, Abul Kashem Shaheb, was a resident of the Rahmatganj area in Old Dhaka. The other founding members were Alauddin, Md. Azam, Ahmad Hossain, Md. Sadek, and Abu Saeed from Imamganj. Abdus Sobhan and Md. Kashem served as the club's first president and general secretary, respectively. Originally, the club operated as a social service institution, but gradually it became involved in sports. As a result, the club began participating in various football tournaments held in Dhaka, forming a team with the area's youth. In 1950, Md. Kashem, held a meeting with the general Secretary of Dhaka District Sports Association at the time,
Khwaja Ajmal, and arranged the fee required to enter the
Second Division. The club remained active in the league until their eventual relegation in 1954, after finishing the season bottom of the table with four points and without a single victory. In 1963, under president Md. Aref Mia Sardar and general secretary M.A. Awal, the club became champions of the
Third Division.
The First Division era (1965–1993) In 1965, the club entered the
First Division under the captaincy of QM Rafique Dipu. was sent off, suffered a 1–3 defeat, despite
Hassan Ahmedul Haque giving them the lead. In 1978,
Wazed Gazi took over the club's head coach duties from Noor Hossain and served until 1983. During this time, the club finished third in the league in both 1982 and 1984, the latter under coach
Abdur Rahim. Rahim remained at the post until 1986, after which the club would enjoy regular mid-table finishes. In 1992, they finished fifth in the league, which qualified them, along with that season's top ten teams, to become founding members of the newly introduced top-tier league the following year, the
Premier Division.
Yo-yo years (1993–2007) Relegation to the
First Division came after the club finished ninth with thirteen points from eighteen games during the inaugural edition of the Premier Division in 1993. This marked the end of Rahmatganj's 28-year stay in the top flight. In 1994, under the captaincy of Mohammed Aman, the club became First Division champions and returned to the top-flight on their first attempt. In 2001, with the help of star-striker
Saifur Rahman Moni, Rahmatganj finished the league season in third-place, six points off the eventual champions,
Dhaka Abahani. Moni departed for
Muktijoddha Sangsad KC in 2002, and the club suffered relegation the same year, finishing second from bottom with fourteen points from thirteen league games. In 2004, while remaining a First Division team, the club reached the quarter-finals of the
Federation Cup, where they were defeated 1–2 by Muktijoddha. Eventually, they would gain promotion back to the top-division in 2005 as champions of the 2004–05 First Division with thirty three points from fourteen league games. Their only defeat that season came at the hand of BRTC Sports Club, losing 1–2 at the
BSSS Mostafa Kamal Stadium on 11 July. Initially, with the introduction of the country's first professional football league, the
Bangladesh Football League (introduced as B.League), in 2007, the club was set to participate in the
Senior Division, a merger of the Premier and First Divisions, serving as the second-tier. However, following the withdrawal of Faridpur FA from the new top tier, Rahmatganj was given a place in the professional league as champions of the 2005 First Division.

Arambagh KS 2–1 in a game held on June 2. The club eventually finished at the bottom of the league with thirteen points from twenty games. However, they remained in the top flight as the league introduced a relegation system starting from the
2009–10 season. Eventually, Rahmatganj would be relegated from the league in the
2012 season finishing botton of the table with only nine points from twenty games. Rahmatganj would enter the country's second-tier professional league, the
