Plava Unija
Plava Unija are the organised supporters of the Serbian football club OFK Beograd.
History
When Beogradski Sportski Klub was founded in 1911, the club which dominated the fields of the Kingdom of Serbs, Croats and Slovenes developed a significant fan base. Throughout the several wars that took place since the founding of BSK, the club's turbulent history has produced adverse effects onto the average attendance of today's matches in which OFK Beograd plays.An organized group appeared for the first time in 1984 under the name of "Blue Thunders". The group lived under that name until 1990. When they were influenced by the rise of nationalism in Yugoslavia, they changed their name to "Sokolovi". The group officially collapsed in 1993 about a year after UN sanctions were put on Yugoslavia. The fans' love towards the club was certainly not forgotten and in 1994 a new group is founded – Plava Unija Beograd. The name remains the title of OFK Beograd's main group of ultras.
OFK Beograd's fans have been known to be resistant of past regimes. In the 1990s, FK Milicionar, a pro-regime police-backed team, entered the first division. When OFK Beograd first played against them, the OFK fans reacted with creation of banner which bore the message “Goal Against the Regime”.
