The Yugoslav Football League was the top professional football competition in the former Yugoslavia, established in 1923. It featured clubs from various regions, including Serbia, Croatia, and Slovenia, and was known for its competitive nature and passionate fan base. The league operated under a system of promotion and relegation, with teams vying for the championship title each season. The league was dissolved in 1992 due to the breakup of Yugoslavia and subsequent conflicts. Its legacy continues through the formation of national leagues in the successor states, such as the Prva Liga in Croatia and the SuperLiga in Serbia.
