The evolution of human societies has been accompanied by shaping political cleavages. The emergence of the nation state system and its development deepened and institutionalized political cleavages in their various aspects. These cleavages, if continue, can foster political rivalries and division and would have a great impact on the political destiny of states. In fact, political behavior and electoral competition result from active cleavages in different times in various political systems. Therefore, political cleavages are among important topics of politics and are considered as major problems for states. The processes of modernization and democratization are coupled with the emergence of new cleavages that the recognition of them is necessary for maintaining political stability and equilibrium and developing the civil society.
