During the late 1980s, the former Socialist Federal Republic of Jugoslavia (SFRJ) – a country dominating the Balkans – experienced a period of major crisis. Led by the Communist Party, the nation's leadership failed to understand the depth of political changes all over Eastern Europe, and then split along ethic lines. In 1988-1989, ethnic Albanians in the autonomous province of Kosovo began demanding independence: the authorities of the SFRJ reacted by suppressing the resulting demonstrations. In the Federal Republic of Serbia, public opinion slid into nationalism, which the local communist leadership exploited to maintain itself in power. By 1990, nationalistic leaders rose to power in Slovenia and Croatia, and publicly announced their intention to secede these federal republics. Under the heavy shadow of growing war-mongering, politicians from all three sides met to reach settlements on the division of their and their emerging nation's interests. The last few influential supporters of the preservation of a federal state were quickly pushed aside, and the powerful military of the SRFJ – the Yugoslav Popular Army (Jugoslovenska Narodna Armija, JNA) – became an instrument of political games. The Slovenian and Croatian proclamations of independence, in June 1991, proved to be the drop that over spilled the barrel. Already split by deep rifts within their top political and military leaders, the federal authorities launched a rather confused attempt to recover control over the external borders of the SRFJ. The nascent Slovenian military resisted, causing a series of bloody clashes with the JNA. Tasked with the transport and protection of federal employees, the Yugoslav Air Force and Air Defence (JRViPVO) found itself in the thick of combat from day one of this conflict, when the Slovenes shot down two of its helicopters. In return, the JRViPVO began flying attack sorties, which ended only through a political agreement of 2 July 1991, and the decision for Yugoslav authorities to withdraw from Slovenia. 110 photographs, 10 maps, 12-15 colour profiles
