Soon followed foundation of the football clubs “BASK”, “Srpski mač”, “Soko” and “Dušan Silni”... Increasing number of clubs enabled more matches, and, in time, it was only natural that the need arose for playing matches abroad. The first who took this adventure was FK “Srpski mač”. They scheduled the match vs. the team “HAŠK” from Zagreb (Croatia) for the spring 1911. The club management did not approve this match, yet the players still decided to travel to Zagreb to play the match, however not under the name of their club, but as the “National Team of Kingdom of Serbia”.

Although the matches were of a friendly character and unofficial, these meant the first appearance of Serbia on a football pitch, and an important historical event. The national team of Serbia has played its first match on 19th May 1911, and lost from HAŠK by 0:8. The next day, on 20th May, it played the second match, which it also lost by 0:6. The Zagreb newspapers reported from these matches with credits to Serbian team for its efforts and braveness to challenge the much better rival. Already then the Serbian newspapers showed that the Serbian public did not easily accept the defeat, although it was part of the game. The management of the “Srpski mač” was rigorous: it has excluded the disobedient players from the club.

bskThe “rebellions” did not give up the game, and on 1st September 1911 they founded the Belgrade Sports Club (BSK). In the next three decades, until the Second World War, this club dominated the Serbian scene, and became the best team of the Kingdom of Yugoslavia, with five titles of the state champion. After the First World War the boundaries of Balkan countries were changed. The Kingdom of Serbs, Croats and Slovenians was founded, and its name was changed into Kingdom of Yugoslavia on 1st December 1919. Serbia became a house of people from Triglav to Đevđelija and football obtained a new form.

The new state needed the house of football, and on 18th April 1919the Football Association (“Jugoslovenski nogometni savez”) was founded at the meeting in Zagreb. The founding assembly in Zagreb was presided by Mr. Danilo Stojanović, legendary “Čika Dača”, founder of football club “Šumadija”, the “BSK” football club and some other football clubs, which was a fact proving Serbia as the strongest pillar of the state football association.

It was decided that the association should be divided into regions. Serbia was represented by the Belgrade sub-association, which comprised central Serbia, Vojvodina, and Kosovo and Metohija. Hence, 18th April 1919 is regarded as the founding date of today’s Football Association of Serbia.

The formation of the new organization was an incentive for foundation of new clubs. By 1930 already 51 football clubs were registered in Belgrade, while the Belgrade Football Association had 91 members. The increase of number of clubs, and the quality required the organization of competitions, so already in 1920 the first championship of the city clubs took place in Belgrade.

City fields became too small for the best clubs and so the first state championship was launched in 1923. The championships were played, with occasional interruptions, until 1940, and in this period the best Serbian clubs won seven state championship titles: FK BSK five and FK SK Jugoslavija two.
