In the article, in the context of the archetypal approach, the interaction of the authorities and the opposition in the course of implementing the decommunization policy was analyzed. An integral part of a decommunization policy was changing the Soviet names of toponymic objects in residential places bearing the Communist totalitarian regime symbols that consecrated persons involved in the crimes of the latter, also the events related to the activities of the Communist Party, the development of Soviet power in Ukraine, the persecution of participants in the struggle for Ukraine’s independence in the XX century. The Soviet archetypal basis of decommunization methods in Ukraine is revealed, which it was testified to the rapid pace of policy, the lack of information support, explanations, especially for the population of the central and eastern regions of Ukraine, for which the Soviet symbolices was continues to be valuable. The imperial/Soviet archetypes of interaction between the authorities and the opposition are defined by the example of renaming of Soviet names for objects of toponymy of settlements containing symbols of the communist totalitarian regime. Polarized regionalism of Ukrainian society, two distinct national identities based on different systems of political values, have formed various archetypes. Thus, in Uzhgorod and Kirovohrad, the influence of the imperial (respectively, Austrian and Russian) archetypes was reflected. The opposition of some city councils of the Naddnipryanshyny and eastern Ukraine to the parliament’s decisions was sometimes determined not by the number of opposition, but by the Soviet identity of the deputy corps. The existence of a confrontational type of the interaction between parliamentary opposition and government/president is substantiated; also between the opposition, embodied by the local political and management elite of Kirovohrad, Kharkiv and Komsomolsk of Poltava’s region, and the state power, personified by the head of the relevant regional state administration/parliament. It is proved that the conformal type is inherent of interaction the opposition, which is represented by the city council of Dnipropetrovsk and the authorities represented by the respective mayor/parliament; also the interaction between opposition, which represented by the city council/mayor of Uzhhorod and the authorities, which is represented by the chairman of the Transcarpathian Regional State Administration.
