Political Science is a vast discipline and is constancy expanding. It can be subdivided into several specialized areas and subdivisions. They are, to mention the important ones, national politics, comparative politics, public administration, political dynamics, local government, and international relations.
Moreover, Political Science depends upon and derives much of its knowledge and information from other social sciences. However, we shall discuss its relations with other social sciences in a later chapter. In this chapter we shall consider its various subdivisions. Following Alfred de Grazia, we may present the whole field or conspectus of Political Science in the form of a diagram as thus:
The conspectus of Political Science provides us a panoramic view of almost all the sub-divisions or sub-fields and approach factors to it. W shall now discuss its Sub-divisions briefly.
