Political science is basically divided into three distinct sub-disciplines: political philosophy, comparative politic and international relations. Political philosophy is the reasoning for an absolute normative government, laws and similar questions and their distinctive characteristics. Comparative politics is the science of comparison and teaching of different types of constitutions, political actors, legislature and associated fields, all of them from an intrastate perspective. International relations deals with the interaction between nation-states as well as intergovernmental and transnational organizations.
