Borac (Serbian Cyrillic: Бopaц) is a sports society with several teams, from the city of Banja Luka, Republika Srpska, Bosnia and Herzegovina. Borac means "Fighter" and the clubs supporters are called Lešinari/Лешинари which means Vultures. The club is the champion of Premier League of Bosnia and Herzegovina for 2010/2011 season. The football club Borac was founded on July 4, 1926. Originally it was named Radnički sportski klub Borac, meaning Workers' Sports Club Borac. It was founded by a group of football aficionados including Veselin Masleša, Rudolf "Rudi" Hiter, Savo Novaković, Mustafa Softić, Nikola Kuković and others. The club's first success in this early period came in 1928 when it won a tournament played in Sarajevo. Borac was renamed Fudbalski klub Borac (Football Club Borac, FK Borac) in 1945. It played two years in the Yugoslav Third League before it advanced to the Second League in 1953. It gained promotion to Yugoslav First League for the 1961/62 season, but promptly dropped back down at the end of it. The club would wait almost a decade for a return to top flight – 1970/71 was the season, and the stay in top league was longer this time around – four consecutive seasons. The 1974/75 season was spent in Second League where the club achieved quick promotion and thus ensured the beginning of a new 5-year First League period that lasted until 1980. The following nine seasons were spent in Second League, before a final top league stint between 1989 and 1992. Borac's best placement in the First League was 1990/91 when it finished fourth. FK Borac was the runner-up in the 1975 Yugoslav Cup, and won it in 1988 as the only Second League club to ever achieve this. The club also won the Mitropa Cup (Central European Cup) in 1992. It played a total of eight games in UEFA competitions. Seven Borac players participated in the Yugoslav national football team and its stadium, the City Stadium of Banja Luka (capacity: 7,238), hosted five international matches. Borac Banja Luka in recent times had great success by winning three First League of the Republika Srpska titles, first one in 2000/2001, the second in 2005/2006 and the third in 2007/08. FK Borac Banja Luka is one of the oldest football clubs from former Yugoslavia. Borac supporters group "Лешинари"/"Lešinari" are formed in 1987.They have been involved in a number of fights with rival supporters such as FK Sarajevo, NK Čelik, Zrinjski and Željezničar.
