Geopolitics
Geopolitics (from Greek γῆ "gê" "earth, land" and πολιτική "politikḗ" "politics") is the study of the effects of geography (human and physical) on politics and international relations. While geopolitics usually refers to countries and relations between them, it may also focus on two other kinds of states: "de facto" independent states with limited international recognition and; relations between sub-national geopolitical entities, such as the federated states that make up a federation, confederation or a quasi-federal system.
