This club played a big role in cultural and sport autonomy of Bačka Croats in southern Hungary in Austria-Hungary, and later in Kingdom of Yugoslavia.
The club was founded in 1901. Its original name in Hungarian was Bacska Szabadkai Athletikai Club. Among its founders the most common nationality was Croatian, and the club's emblem bore the Croatian chequy in the upper-left corner.
The club played in Hungarian leagues in its early years, regularly winning the league of Southern Hungary. It later participated in the Yugoslav championship twice, in its 1923 inaugural season and in 1925. During this time the club was named JSD Bačka. Upon the formation of the Croatian-Slovenian League and later the Croatian First League within the Banovina of Croatia, the club changed its name to HAD Bačka and competed with Croatian clubs.
After Hungary annexed the Bačka region in 1941, the club was forced to compete in the Hungarian League, where it entered competition in its third-tier. In 1945 the club was renamed to HAŠK Građanski (Croatian Academical Sports Club Građanski) after the famous Zagreb side. Soon after the Communist Yugoslav regime, in the action of extinguishing the Croatian sport and cultural societies and clubs in autonomous province of Vojvodina, forced the club to be renamed to FD Sloboda, removing the attribute "Croat" from the club's name, as it has been done with all other Croat societies and clubs in Vojvodina. After a few more name changes, the club returned to the name Bačka in 1963, but still without the Croat attribute in the club's name.
NK Bačka 1901 currently (as of Feb 2008) competes in a regional league North within Vojvodina.
NK Bačka 1901 gave several players that played for the team of Croats in Serbia, that became European runners-up and silver medalists in Europeada 2008.
