History The club was founded on 10 March 1958 by GP Rad, a local construction company. They acquired the league rights from FK Razvitak, a small club based in Banjica, going on to compete in the local leagues of Belgrade until the early 1970s. The club earned promotion to the Yugoslav Second League in 1973, spending the next 14 seasons in the second tier of Yugoslav football. They also reached the 1981–82 Yugoslav Cup quarter-finals, losing to Dinamo Zagreb. In the 1986–87 Yugoslav Second League, the club became champions in Group East and took promotion to the Yugoslav First League for the first time in history. They placed 15th in their debut appearance in the top flight, just one point above the relegation zone. The club subsequently finished in fourth place in the 1988–89 season, earning a spot in the 1989–90 UEFA Cup. They were eliminated in the first round after losing 3–2 on aggregate to Olympiacos. Following the breakup of Yugoslavia, the club continued to compete in the top flight, placing fifth in the 1992–93 First League of FR Yugoslavia. They would also place in the top five in three consecutive seasons from 1998 to 2000. With the beginning of the new millennium, the club slowly started to decline and eventually suffered relegation in the 2002–03 season. They returned to the top flight of Serbia and Montenegro football in its final edition, but were promptly relegated. After spending two seasons in the Serbian First League, the club placed fourth in 2007–08, managing to earn promotion to the Serbian SuperLiga via playoffs. They finished fourth in 2010–11, which meant qualification for the 2011–12 UEFA Europa League and a return to European football after 22 years. After spending 13 consecutive seasons in the top flight, the club suffered relegation in 2021.
