Geopolitics and Borders

About this topic

Geopolitics studies how geography influences politics and power. Borders may follow natural features (rivers, mountains) or be geometric lines drawn by colonisers, often ignoring ethnic groups, which can lead to conflict. At the 1884-85 Berlin Conference, European powers divided Africa with little regard for local peoples, and many straight-line borders there still divide or combine communities.

Disputes arise over land, resources (oil, water), sea routes (such as the South China Sea) and sovereignty. A strait or canal, like Suez or Hormuz, can be a chokepoint through which much of the world's trade or oil passes, giving great strategic importance to those who control it. States may form alliances and organisations (NATO, EU, African Union) to increase security and trade.

Concepts: sovereignty (a state's right to govern itself), nation-states, buffer zones, and exclusive economic zones (200 nautical miles from the coast, where a country controls marine resources). Resource competition and climate change reshape the strategic landscape; melting Arctic ice, for example, opens new shipping routes and fuels competition over resources. A common misconception is that borders are fixed and natural; most are human creations that change through war, treaty and negotiation.
