This is a study about the transition process and the consolidation of power in Belarus. In this paper the concept of "authoritarian state building and the sources of regime competitiveness in the fourth wave" is the major theory used. After giving a description of the theory‟s concepts a short historical background of Belarus follows. Chapters four describes and explain the political situation in Belarus during five periods. After each period I analyze the situation on the basis of the suppositions from the theory. The thesis also tries to explain the conditions needed for an authoritarian regime to be established. The result of the concluding discussion shows that the major theory in this thesis presents important factors that can help to explain why and how the autocratic rule in Belarus has been consolidated.
