Following the rise of nationalism and political tensions, as well as the outbreaks of the Yugoslav Wars, numerous anti-war movements developed in Serbia. The 1991 mass protests against Slobodan Milošević regime which have continued throughout the wars reinforced young people's antiwar orientation. The demonstrations in Belgrade were held mostly because of opposition the Battle of Vukovar, Siege of Dubrovnik and Siege of Sarajevo, while protesters demanded the referendum on a declaration of war and disruption of military conscription.
