Political geography as a sub-discipline of geography is concerned with the study of political space of geographical space. In other words, it studies those structures and phenomena which are intertwined with politics, and those processes and the ways in which political processes are themselves affected by spatial structures. Conventionally, for the purposes of analysis, political geography adopts a three-scale structure with the study of the state at the center, the study of international relations (or geopolitics) above it, and the study of localities below it. The primary concerns of this sub-discipline can be summarized as the inter-relationship between people, state, and territory. Political geography has extended the scope of traditional political science approaches by acknowledging that the exercise of power is not restricted to states and bureaucracies, but is part of everyday life. This has resulted in the concerns of political geography increasingly overlapping with those of other human geography sub-disciplines such as economic geography, and, particularly, with those of social and cultural geography in relation to the study of the politics of place. Contemporary political geography often considers spatial and temporal domains, spatial feelings and bondage, patriotism and citizenship, states, borders, capitals, central places, local governments, regional political-spatial structures, geopolitical territories, crisis geographic spaces, spatial actions on different scales, dynamics of space and politics, spatial manifestations of interaction of politics and geography, spatial patterns of voters and elections, domains of division, national divisions, political organization and arrangement of space, space policy management, geography and national strategy, tourism, peace and security, environment, international migration, regional and global systems etc. Therefore, the philosophical basis of political geography concerns the places, spaces, and phenomena created by the merging of geography and politics. In other words, political geography and its relevant sub-disciplines study those spatial / geographical constructions and phenomena that have political value, political identity or political function. That part of the political geography which is linked to the component of power, that is to say, the interaction of geography, politics and power, falls within the realm of 'geopolitics' a sub-discipline of political geography. The development of such studies and the discovery of rules and modeling of the interrelationship between political-spatial variables can pave the way for the application of geopolitical science and geopolitics in the field of administration and foreign relations, in particular, the optimal allocation and management of political and geographical spaces (countries, political / spatial units within the country, cities and central places, borders, etc.) as well as domestic and national security of countries and foreign relations with other countries. Also, the geographic analysis of global and regional developments and crises, and an understanding of the nature and state of the state's political behavior at the national, regional and global levels, and their divergence and convergence, in terms of geographical and spatial origins are issues which can be handled by political geographers.
