[2] Before the formation of the BLP, football clubs in Serbia lacked an organised competition and limited to play friendly or exhibition matches.
The formation of BLP joined a number of willingfull and passionate people who will improve the management and organisation of football in Serbia, turning it into a more developed and professionalised activity.
This greatly contributed for the mass popularisation of football and the quality gap that existed in comparison to other footballistically more developed countries started to be diminish.
[3] That year the subassociation counted with only 66 clubs, 19 of which in the city of Belgrade itself, 9 in the district (župa - administrative unit) of Banat, 3 in Brčko, 4 in Bijeljina, 4 in Leskovac, 3 in Vranje, 2 in Skoplje, 3 in Zemun, 1 in Šabac, 2 in Sremska Mitrovica, 2 in Užice, 1 in Požega, 1 in Jagodina, 2 in Čačak, 1 in Ruma, 1 in Negotin, 1 in Kruševac and 1 in Veles.
[5] The conference from 15 January 1922 was marked by the decision to strengthen the relations with the peripheral provincial clubs, and the territory was divided among Župa's, administrative units corresponding in English language to parishes or districts.
[6] In the general assembly held on 2 July 1922, a new administration was elected with Danilo Stojanović, popularly named as Čika Dača (Unckle Dacha) as its president.
[17] Until 1927 the champion gets automatically qualified to the Yugoslav Championship, but since that year, the second placed teams of the leagues of Belgrade and Zagreb also get a chance to play on the national highest level by participating in one elimination round.
This period was marked by the fierce rivalry between the two most ambitious clubs, BSK and Jugoslavija, respectively named the Blues and the Reds.
There they would face another aspect of Yugoslav football of the era, the equally fierce rivalry between the Belgrade teams and those from Zagreb.
SK Jugoslavija was completely disbanded with most of its property and players, including the field, handed over to the newly formed Red Star Belgrade, while BSK, although initially also disbanded, it ended being restored as OFK Beograd, a medium-small size club with obviously lower ambitions than BSK, and even so their right to assume and claim the continuity was only accepted after the socialist regime ended.
