now count on four votes at a minimum: Serbia proper, then-loyal Montenegro, Vojvodina, and Kosovo. As a result of these events, ethnic Albanian miners in Kosovo organised the 1989 Kosovo miners' strike, which dovetailed into ethnic conflict between the Albanians and the non-Albanians in the province. At around 80% of the population of Kosovo in the 1980s, ethnic-Albanians were the majority. With Milosevic gaining control over Kosovo in 1989, the original residency changed drastically leaving only a minimum amount of Serbians left in the region. The number of Slavs in Kosovo (mainly Serbs) was quickly declining for several reasons, among them the ever-increasing ethnic tensions and subsequent emigration from the area. By 1999 the Slavs formed as little as 10% of the total population in Kosovo. Meanwhile, Slovenia, under the presidency of Milan Kučan, and Croatia supported the Albanian miners and their struggle for formal recognition. Initial strikes turned into widespread demonstrations demanding a Kosovan republic. This angered Serbia's leadership which proceeded to use police force, and later even the Federal Army was sent to the province by the order of the Serbia-held majority in the Yugoslav Presidency Council. In January 1990, the extraordinary 14th Congress of the League of Communists of Yugoslavia was convened. For most of the time, the Slovene and Serbian delegations were arguing over the future of the League of Communists and Yugoslavia. The Serbian delegation, led by Milošević, insisted on a policy of "one person, one vote", which would empower the plurality population, the Serbs. In turn, the Slovenes, supported by Croats, sought to reform Yugoslavia by devolving even more power to republics, but were voted down. As a result, the Slovene and Croatian delegations left the Congress and the all-Yugoslav Communist party was dissolved. The constitutional crisis that inevitably followed resulted in a rise of nationalism in all republics: Slovenia and Croatia voiced demands for looser ties within the Federation. Following the fall of communism in Eastern Europe, each of the republics held multi-party elections in 1990. Slovenia and Croatia held the elections in April since their communist parties chose to cede power peacefully. Other Yugoslav republics—especially Serbia—were more or less dissatisfied with the democratisation in two of the republics and proposed different sanctions (e.g. Serbian "customs tax" for Slovene products) against the two, but as the year progressed, other republics' communist parties saw the inevitability of the democratisation process; in December, as the
