The syntagm about the alleged plebiscite unity that pervaded Slovenia in the fall of 1990 has become a permanency in Slovene politics and, at least partly, in the language of politology and history. At the time, a decision had to be made whether Slovenia should organize on December 23, 1990 a plebiscite about its departure from the state of Yugoslavia to begin a new life as an independent country. This paper examines several subjects: reactions of Slovene politicians to the initiative about the plebiscite that was proposed by the Socialist Party of Slovenia in October 1990; the decision for the plebiscite a year later that was supported by the Democratic Opposition of Slovenia (the DEMOS) in Poljče; and the reaction of oppositional parties as well as the ones within the DEMOS to this second initiative that ultimately led to its goal - independent Slovenia. The author wonders if it is legitimate to speak of the plebiscite politicai unity rather than merely of plebiscite unity o f Slovenes, 88.5 percent of which on December 23, 1990 opted for an independent and autonomous state of Slovenia.
