History Founded in Sarajevo during 1908 when the city was part of Austria-Hungary, the football club was part of the wider sports society of Sarajevo gymnasium students informally known as Đački sportski klub (ĐSK) or Srednjoškolski sportski klub (SSK). Since cultural and social activities in the city in those days mostly revolved around Hotel Evropa and the gymnasium, the idea of establishing a sporting club was initiated on those premises.

Notable individuals who organized club activities in this early period were students Zdravko Jeftanović (son of the Hotel Evropa owner dr. Dušan Jeftanović), Feodor Lukač, Emil Najšul, Sveto Gerovac, Stevo Jokanović, etc. Their early activities were very sporadic and basically clandestine as Austro-Hungarian occupational authorities that just annexed Bosnia instituted a ban on any kind of organized gathering. In early 1909, the football section got its first pairs of boots and started holding regular practices and training sessions at Sarajevo Polje grounds, more precisely the military workout open facility known as Egzercir in the Čengić vila area. Since the open field didn't have any goalposts, the students had to haul them in on foot from the city for every practice and match. ĐSK/SSK also informally took red and white as club colours after Slavia Prague, the club that served as inspiration for Slavs throughout Austria-Hungary. Austrian international striker, Karl Harmer, came from Vienna to become the team's first manager. 1910s It wasn't until 1911 that ĐSK played its debut match, defeating a selection of Vienna soldiers 4–2.
