Why the Caucasus Is a "Shatter Belt": Geography, Ethnicity, and Great Power Rivalry

The Caucasus (between Black and Caspian Seas) is a classic shatter belt—a zone of persistent fragmentation and conflict caught between rival powers.

Eight Drivers

1. Crossroads Location: Europe-Asia transit corridor; pipelines, trade routes.
2. Extreme Ethnic Diversity: 50+ groups (Georgians, Armenians, Azerbaijanis, Chechens, Circassians, Ossetians, etc.) with distinct languages, histories, territories.
3. Historical Layering: Persian, Ottoman, Russian, Soviet empires left overlapping claims, borders, grievances.
4. Great Power Competition: Russia, Turkey, Iran, EU/US vie for influence; energy routes (BTC pipeline) intensify stakes.
5. Resource Wealth: Oil/gas (Azerbaijan, Caspian), minerals, water—fuels external intervention.
6. Weak Institutions: Post-Soviet state-building incomplete; corruption, patronage, frozen conflicts (Abkhazia, South Ossetia, Nagorno-Karabakh).
7. Separatist Movements: Ethno-nationalist bids for autonomy/independence met with force.
8. External Proxy Support: Neighbors arm/finance opposing sides, preventing resolution.

Result: recurrent wars, displacement, militarization, stalled development. Stability requires inclusive governance, regional cooperation, and great-power restraint—all elusive.
