The changes which occurred on the post political totalitarian systems indicated upon the fact that the political process was profoundly influenced by the ethnic factor. Therefore M.Weber, sustained the idea that the ethnic identification is the aim of the political life. This important dimension may be latent or absent in this important dimension in the West, but at the full scale in the East states [18, p.27-28]. We sustain the idea that contemporary political process of post-totalitarian states was and is deeply ethnically, there were written the numerous works about it. The Republic of Moldova is part of this group of countries, and this article is to motivate and shape the overall landscape, regarding the Moldovan ethnic dimension of the political process. Based on the proposed topic for research, this paper will form the basis of theoretical and conceptual work, the first paragraph will argue the consolidation of regionalism in Republic of Moldova as a modality to integrate ethnic groups.
