In 1981 there was an outburst of Albanian nationalism. Prishtina university became a centre for some nationalistically orientated students that generated Kosovar Albanian protests (1981) over social grievances that marked the first large scale expression of nationalism in Yugoslavia since the Croatian Spring (1971). Kosovar Albanian communists condemned the protests and supported Yugoslav unity while leading the campaign against Albanian nationalism and in that sense shared the view of other Yugoslav communists. The Islamic Community of Yugoslavia dominated by Slavic Muslims distanced itself from the protests, expressed anti-Albanian sentiments and condemned Albanian irredentism estranging Albanian Muslims from establishment Sunni Islam. Albanian Sufi sheikhs instead promoted Sufism among Yugoslav Albanians as an alternative, more traditional and decentralised form of Albanian Islam. The unification of Albanians in the Balkans into one state was also a feature of Kosovar Albanian nationalism and these views were confined to dissident and underground groups. Within the context of the 1981 protests these groups, many with left-wing political orientations united to form the "People's Movement of Kosovo" (LPRK) in Germany (1982). Unification of Albanians into one state was a demand viewed as separatism and irredentism in Yugoslavia which was banned. Kosovar Albanian nationalists were divided into groups with one that wanted to focus on the Albanian question as a whole and the other mainly focusing on Kosovo.
