The article deals with the evolution of the political system in the Slovak Republic following the dissolution of Czechoslovakia with an indication of the non-democratic trends emerging from 1993 to 2016. Based on democracy indicators, there are two periods in which manifestations of non-democratic behavior occured and they triggered a response from the international community in the form of criticism of the government’s actions and lowering the democratic views of the country. The first period covers the years of Prime Minister Vladimír Mečiar’s rule ( 1993–1998), and the second one concerns the years 2006–2010 when Robert Fico’s First Government was active. The author points out the causes, manifestations and effects of these non-democratic behaviors for the political system, internal and foreign policy of the Slovak Republic.
