Geopolitics
Geopolitics (from Greek γῆ gê "earth, land" and πολιτική politikḗ "politics") is the study of the effects of Earth's geography (human and physical) on politics and international relations.[1][2] 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.
