Civilization

# Steppe / Central Eurasian

The Eurasian steppe corridor generated distinctive mobility-based polities and cultural repertoires that recurrently transformed agrarian cores across Afro-Eurasia.

## The framework read

The author's reading of this civilization.

- Geographic core: steppe corridor from Pontic–Caspian to Mongolia enabling large-scale mobility.

- Cultural-linguistic cohesion: shared nomadic institutional repertoires and steppe diplomatic-military systems.

- Political-economy: tribute, trade control, and confederation/imperial structures integrated with agrarian peripheries.

- Continuity: recurrent formations (Xiongnu, Türk, Mongol, later successor polities) with recognizable civilizational patterns.

### Why it works — and how it breaks

- Success vector: G (mobility, cavalry, logistics) + S (pragmatic administration, confederation structures) → enables conquest and tribute extraction.

- Failure modes: S fragmentation (succession disputes, confederation breakdown) + G tech lag (gunpowder shifts advantage) → assimilation into agrarian cores or transformation into successor states (see comparison-turko-persian-synthesis).

### By the numbers †

- GDPpeak ~$1.8 billion in 1300 CE, ~1% of world GDP, very low due to low population density, mobility-based economy, tribute extraction

- Population2-4 million, very low density 0.5-1.5/km², mobility-based organization

- Urbanization2-12% urban population, very low urbanization, largest city: Karakorum 50K-80K in 1300 CE, mobility-based organization

- Fiscal Capacitytax revenue: $0.04B-$0.14B, tax-to-GDP ratio: ~8% includes tribute, military spending: 40-50% of tax revenue, tribute-based fiscal systems, mobility-based organization, different fiscal mode

- Technology Index38→44, moderate level, mobility-based adaptations - lower agricultural 7/20, higher military 11/20, cavalry excellence, Silk Road integration, innovation rate 2-5 per century

- Institutional Metrics3-6 officials per 10K, 55% tax efficiency, 50-150 legal provisions, low-moderate, mobility-based, tribute-based systems, lowest globally

- Demographic Structure39-40% under 15, 25-32 years life expectancy, 5-6 fertility, 36-43 mortality, very high youth proportion highest globally, mobility-based, very high mortality

- Infrastructure15,000-25,000 km trade route roads, 500-1,000 km canals, 100 fortifications, 60 bridges, 58/100 sophistication index, Silk Road routes, mobility-based organization limits infrastructure, low
