Polarity (international relations)

Polarity in international relations is any of the various ways in which power is distributed within the international system. It describes the nature of the international system at any given period of time. One generally distinguishes four types of systems: unipolarity, bipolarity, tripolarity, and multipolarity for four or more centers of power. The type of system is completely dependent on the distribution of power and influence of states in a region or globally.
