Andean Civilization

The Andean highlands and littorals sustained complex polities with distinctive infrastructural, ritual, and economic systems forming a durable civilizational complex.

Andean

Details

• Geographic core: Andean highlands with vertical archipelagos linking ecological tiers; coastal nodes.
• Cultural-linguistic cohesion: shared ritual infrastructures and state cults; Quechua/Aymara spheres in later periods.
• Political-economy: labor taxation (mit’a-like systems), road networks, and storage regimes.
• Continuity: recognizable civilizational patterns across Chavín, Moche, Wari, Tiwanaku, and Inca.

GGS Assessment

• Success vector: S (vertical archipelago coordination, road networks, storage regimes) + G (organized defense, labor mobilization via mit'a).
• Failure modes: S fragmentation (succession disputes, regional competition) + B disease catastrophe at contact (Columbian Exchange) → rapid collapse; internal breakdown in some cases (Wari, Tiwanaku).

Quantitative Data

• GDP (500-1500 CE): See Andean Civilization GDP Data 500-1500 CE for GDP and GDP per capita estimates (peak ~$4.8 billion in 1500 CE, ~3% of world GDP, highland adaptation, vertical archipelago coordination)
• Population (500-1500 CE): See Andean Civilization Population Data 500-1500 CE for population estimates (3-12 million, moderate growth, highland adaptation, pre-contact peak ~12 million in 1500 CE)
• Urbanization (500-1500 CE): See Andean Civilization Urbanization Data 500-1500 CE for urbanization estimates (20-30% urban population, high urbanization, largest city: Cusco 100K-150K in 1500 CE, vertical archipelago coordination)
• Military Size (500-1500 CE): See Andean Civilization Military Size Data 500-1500 CE for army size estimates (50,000-200,000 warriors, peak 150,000-200,000 in 1500 CE, labor-based organization via mit'a, highland adaptation)
• Fiscal Capacity (500-1500 CE): See Andean Civilization Fiscal Data 500-1500 CE for fiscal capacity estimates (tax revenue: $0.10B-$0.38B, tax-to-GDP ratio: ~8%, military spending: ~50% of tax revenue, labor-based fiscal systems, vertical archipelago coordination)
• Technology Index (500-1500 CE): See Andean Technology Index 500-1500 CE for technology index estimates (40→46, moderate level, highland adaptation, isolation impact - low diffusion rate, limited metallurgy 8/20, high agricultural technology 13/20 - vertical archipelago)
• Institutional Metrics (500-1500 CE): See Andean Institutional Metrics 500-1500 CE for institutional metrics estimates (5-9 officials per 10K, 60% tax efficiency, 80-150 legal provisions, moderate, labor-based systems, highland adaptation, isolation impact)
• Demographic Structure (500-1500 CE): See Andean Demographic Structure 500-1500 CE for demographic structure estimates (38% under 15, 28-35 years life expectancy, 5-6 fertility, 34-41 mortality, highland adaptation, very high mortality)
• Infrastructure (500-1500 CE): See Andean Infrastructure Data 500-1500 CE for infrastructure data (35,000-40,000 km qhapaq ñan roads, 1.0-1.5M hectares terraces, 300 fortifications, 350 bridges, 72/100 sophistication index, exceptional highland adaptation, vertical integration, Style axis support)

Key Events

• 7th-9th c. CE: Wari and Tiwanaku states → wari tiwanaku 7thc - Highland state formation, infrastructure development
• 1438 CE: Inca Empire expansion begins → inca expansion 1438ce - State consolidation, infrastructure development
• 1492 CE: Columbus reaches Americas → Columbus Reaches Americas (1492 CE) - Columbian Exchange begins, Great Divergence catalyst
• 1533 CE: Spanish conquest of Cusco → spanish conquest cusco 1533ce - Inca Empire fall

Early States

• Tiwanaku (c. 300-1000 CE) - Andean state, Titicaca basin
• Wari Empire (c. 600-1100 CE) - Andean empire, central Andes

Late Period

• Chimu Empire (c. 900-1470 CE) - Andean empire, northern Peruvian coast
• Inca Empire (1438-1533 CE) - Andean empire, peak expansion
