FK Borac Kozarska

Football club Borac was established in July 1936 at the initiative of leather workers of Dubica, Vrbas Banovina, Kingdom of Yugoslavia. Originally it was named Radnički sportski klub Borac, which in English language means Workers Sports Club 'Fighter' , and its roots come from the relation the club had with labour movements during the first half of the 20th century.

The founders were Ahmet Ćelam, Vujo Momčilović and Razim Hadžić, workers from Dubica. Players were mainly the workers, as well as poor youths without jobs. At that time, management and players were members of different faiths and nations who lived in the town. Although he was in a weak financial position and performed in the lower ranks of the competition, the Borac was too popular among fellow citizens.

Borac rallied progressive young people and members of the Communist Party. City authorities did not provide any help to the club because he was considered a "red club". On the contrary, they tried in every way to obstruct the Club activities because was considered an enemy of the social system. However, the Borac has managed to maintain a decent sports team.

Besides playing football and participating in the football league, the Borac administration organized mass trips and celebrations of May Day.
