Ewolucja systemu partyjnego i sceny politycznej w Bułgarii w latach 1990-2017 – od dwublokowości do wielopartyjności

Abstract

This article concerns the evolution of the party system and the political scene of Bulgaria after the system transformations. The foundations of this analysis are the results of the elections to the National Assembly in the years 1990-2017. In order to identify the type of the party system, official election results and the effective number of parties index (ENP) were used. This index was used to characterise the party system after 2001. Some conditions from communism time had an influence on the shape and kind of how the Bulgarian party system and political scene evolved after system transformation. Between 1990-2001 in Bulgaria, a two-block or two and a half-block party system existed. From 2001 it evolves in the direction of a multiparty system.
