The football club Jedinstvo had been founded on 2 July in 1967, only 12 years after Mali Zvornik municipality was formed. The club had several short time-lasting predecessors under different names mainly related to nearby hydroelectric power plant, but in the end foundators agreed that the name of the club will be Jedinstvo (Unity or United), popular name of the Yugoslavian clubs formed during communist period. Also the ethnic structure of the population in the town in initial years of the club had been based on different nationalities so it may be a reason why authorities had chosen exactly this name. Stadium with one concrete stand, near the elementary and high school and very close to the Drina river bank will stay the home ground since the establishment until today. Jedinstvo stayed the symbol of the town and one of the main originator of social life in Mali Zvornik. The colours of the club remained blue and white during the whole 50 years.
The most successful period of the club was in '80s, when Jedinstvo participated in 4th tier (Druga Srpska Liga) of Yugoslavian football system. During this time the Blues also had very good reputation and they played many friendly games with big and respectable Yugoslav clubs such are Eternal rivals FK Partizan and FK Crvena zvezda.

In the last 20 years the club competes mostly in lower divisions as a jo-jo club, in relation between 5th and 6th tiers of competition.
