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.

Some of the students earlier that year visited Zagreb, where they got introduced to the game of football, bringing back the first ball to Sarajevo.

[1] 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.

Curiosity from the Split visit was that posters announcing the two matches around the city billed ĐSK as "Osman" for non-specified reasons.

They seemingly found the male Muslim name Osman to be sufficiently funny and decided to print it on the posters as the club's official name.

[3] From the fall of 1912 as the first of eventually two Balkan Wars started raging nearby, just beyond the Austria-Hungary's eastern borders, ĐSK naturally began fostering Pan-Slavic sentiment, and especially the Yugoslav idea (unification of South Slavs), even harder as national and political aspects of club's activities came to the forefront.

While the Balkan League member states (Serbia, Greece, Bulgaria, and Montenegro) were getting rid of the last remains of Ottoman influence, Slavs within the borders of Austria-Hungary were restless to make some dents in the armour of their own occupiers – the Austro-Hungarian empire.

The freshly renamed entity attempted to make its existence public and official, and to that end enlisted its connections through Dušan Jeftanović, a prominent local industrialist and landowner, and Jovo Šošić.

The difficult situation that the club found itself in made its members pull together even harder and by the end of 1913 they built a home ground located at Čurčić Vila in Koševo neighbourhood.

The newly built ground at Čurčić Vila got ransacked and burned by an angry mob of Croats and Bosniaks.

Slavija didn't have luck cause they got as opponents in the quarterfinal Belgrade's SK Jugoslavija, which crashed them 2–5 and later became champions that season.

The league now featured 10 teams, and Slavija again barely avoided relegation, finishing third from the bottom with 7 wins, 1 draw, and 10 losses.

Led by Milan Rajlić and Slavko Zagorac on the pitch, and Risto Šošić from the bench, Slavija first came up against Cetinje's Crnogorac, beating them 5–4 on aggregate.

Encouraged by their previous season's historic runner-up success, Slavija entered the new campaign with high hopes.

Its stadium at Marijin Dvor was renamed "Šesti april" and used for home matches of FK Željezničar and newly formed SD Torpedo.

In 1993, after the break-up of SFR Yugoslavia and the formation of the Football Association of Republika Srpska, FK Slavija was re-formed.
