Inaugural meeting was held on 18 April 1903, under the clear sky, on unoccupied lot in Braće Jugovića Street, where in that time was summer playfield Belgrade's gymnastics association Soko.

People said that this debate had been very long and at some moments also very bitter, until Ljuba Jovanović, newly selected president, did not propose the name “Soko”.

The others have all agreed, so on 18 April 1903. of the old calendar, the first football club in Kingdom of Serbia appeared (Bačka from Subotica had been founded in 1901, two years before Soko, but on territory of Austro-Hungary in that time).

The field in Jugovićeva Street was too tight for the playground so another suitable place in the area known as Bara Venecija was found, between current Belgrade Fair and the main city railway station.

Although the playground was quite far from the city center at that time, "Soko" arranged it well and stayed there for a full 27 years, until the state expropriated it for railway needs.

The final was played on June 16, 1918, on Piazza Dissiena, and after the triumph of Soko's players, the flag of the Kingdom of Serbia flew high on the mast.

Belgrade assembly for the necessities of the railway took away from BASK the playfield in Topčider, so, for some time, the club had no field of their own.

Later, BASK got the playing field behind Belgrade electrical plant, which was attributed to Radnički after the Second World War.

Next season, 1937–38, it accomplished the 4th place, and that was the highest achievement of the club, finishing behind the new champion HAŠK, BSK and Građanski.
