Albania on the other hand gravitated toward Communist China, later adopting an isolationist position. The only non-communist countries were Greece and Turkey, which were (and still are) part of NATO. Religious persecutions took place in Bulgaria, directed against the Christian Orthodox, Catholic and Protestant churches as well as the Muslim, Jewish and others in the country. Antagonism between the communist state and the Bulgarian Orthodox Church eased somewhat after Todor Zhivkov became Bulgarian Communist Party leader in 1956. Zhivkov even used the Bulgarian Orthodox Church for the purposes of his policies. The late 1980s and the early 1990s brought the collapse of Communism in Eastern Europe. As westernization spread through the Balkans, many reforms were carried out that led to implementation of market economy and to privatization, among other capitalist reforms. In Albania, Bulgaria and Romania the changes in political and economic system were accompanied by a period of political and economic instability and tragic events. The same was the case in most of former Yugoslav republics. The collapse of the Yugoslav federation was due to various factors in various republics that composed it. In Serbia and Montenegro, there were efforts of different factions of the old party elite to retain power under new conditions along, and an attempt to create Greater Serbia by keeping all Serbs in one state. In Croatia and Slovenia, multi-party elections produced nationally inclined leadership that followed in the footsteps of their previous Communist predecessors and oriented itself towards capitalism and secession. Bosnia and Herzegovina was split between the conflicting interests of its Serbs, Croats, and Bosniaks, while Macedonia mostly tried to steer away from conflicting situations. An outbreak of violence and aggression came as a consequence of unresolved national, political and economic questions. The conflicts caused the death of many civilians. The real start of the war was a military attack on Slovenia and Croatia taken by Serb-controlled JNA. Before the war, JNA had started accepting volunteers driven by ideology of Serbian nationalists keen to realise their nationalist goals. The Ten-Day War in Slovenia in June 1991 was short and with few casualties. However, the Croatian War of Independence in the latter half of 1991 brought many casualties and much damage on Croatian towns. As the war eventually subsided in Croatia, the war in Bosnia and Herzegovina started in early 1992. Peace only came in 1995 after such events as the Srebrenica massacre, Operation Storm, Operation Mistral 2 and the Dayton Agreement, which provided for a temporary solution, but nothing was permanently resolved.
