AP Human Geography Unit 4 Summary
Political geography is one of the oldest fields in the discipline of geography. Political geographers use the spatial perspective to study political systems from local and regional politics, to national politics, to international politics. At local scales, political geographers study issues like territorial organization, representation, and voting patterns. At national and international scales, geographers study the relationship between physical geography and politics, the historical geography of colonialism and imperialism, the formation of international alliances, and the current political tensions between the wealthy countries of the industrialized north and the poorer countries of the less-developed south.
