Beginning in March 1981, Kosovar Albanian students organized protests seeking that Kosovo become a republic within Yugoslavia. Those protests rapidly escalated into violent riots "involving 20,000 people in six cities" that were harshly contained by the Yugoslav government. During the 1980s, ethnic tensions continued with frequent violent outbreaks against Serbs and Yugoslav state authorities resulting in increased emigration of Kosovo Serbs and other ethnic groups. The Yugoslav leadership tried to suppress protests of Kosovo Serbs seeking protection from ethnic discrimination and violence.
