Basically the study of the effect of geographical factors on politics especially international politics is known as political geography or geopolitics. Political geography has a long tradition of its existence on the academic horizon but not in organised way. The origin of political geography can be traced back to the 17th century. Political geography is concerned with politically organized areas, their resources and extent and the reasons for the particular geographical forms which they assume. This encyclopaedic work, in three volumes, gives a thorough account of all relevant information on the theme.
