- Comparison to other civilizations (500 CE): Moderate disadvantage (~3-6 vs ~8-12 officials per 10K)
- Comparison to other civilizations (1500 CE): Significant disadvantage (~5-9 vs ~12-18 officials per 10K)
Key Events
- 500-1000 CE: Wari/Tiwanaku period - Institutional capacity growth (5-7 officials per 10K, 60% tax efficiency), labor-based systems (mit'a)
- 1000-1200 CE: Regional kingdoms period - Continued institutional capacity growth (5-7 → 6-8 officials per 10K, 60% tax efficiency), regional variation
- 1200-1500 CE: Inca expansion period - Institutional capacity growth (6-8 → 7-9 officials per 10K, 60% tax efficiency), imperial expansion, labor mobilization via mit'a
- Event-data integration: Institutional capacity growth (5-7 → 7-9 officials per 10K, 60% tax efficiency) linked to Wari/Tiwanaku (500-1000 CE), regional kingdoms (1000-1200 CE), and Inca expansion (1200-1500 CE), with labor-based systems (mit'a) enabling institutional capacity

About this entry
A draft entry preserved from civilization.study. Evidence grade: medium. 2 of 2 listed sources are fully documented; the rest are names only. † marks figures that are scholarly estimates. Method and sources
Methodology Notes
- Estimation method:
- Bureaucratic size based on archaeological evidence, historical records, expert assessments
- Tax collection efficiency based on tax revenue vs estimated potential GDP
- Legal code complexity based on legal code analysis, court system size
- Literacy rates based on quipu records, expert assessments
- Educational institution count based on archaeological evidence, historical records
- Data quality: Medium (archaeological evidence, historical records, expert consensus)
- Uncertainty range: ±30% for bureaucratic size, ±15% for tax efficiency, ±25% for literacy rates
- Limitations:
- Bureaucratic size estimates depend on archaeological record completeness
- Tax collection efficiency requires GDP estimation
- Literacy rates difficult to estimate for general population (quipu-based)
- Regional variation within Andean civilization not captured
- Cross-validation:
- Archaeological evidence validates bureaucratic size
- Tax records validate tax collection efficiency
- Legal code analysis validates legal complexity
- Quipu records validate educational systems
Integration with Corpus
- Links to claims: Andean Civilization (supports GGS Style axis assessment - institutional capacity)
- Supports patterns:
- Fiscal Systems and State Capacity (moderate tax collection efficiency supports fiscal capacity)
- Andean Highland Adaptation and Vertical Archipelago (vertical archipelago coordination, labor-based systems)
- Institutional Ossification and Civilizational Decline (moderate institutional complexity, lower ossification risk)
- Guns–Germs–Style (GGS) Axes and Success/Failure Mechanisms (moderate institutional capacity supports Style axis)
- GGS implications:
- Style axis: Moderate institutional metrics (5-9 officials per 10K, 60% tax efficiency, 80-150 legal provisions) support moderate Style axis assessment - moderate bureaucratic capacity, moderate legal sophistication, and low-moderate educational systems enable institutional coordination and state capacity
- Institutional Capacity: Moderate bureaucratic size and tax collection efficiency indicate moderate administrative capacity and state coordination
- Legal Sophistication: Moderate legal code complexity (80-150 provisions) indicates legal sophistication and dispute resolution capacity
- Educational Systems: Low-moderate educational institution count (6-10 per 100K) indicates low-moderate knowledge transmission capacity
- Framework integration:
- CAD: Institutional domain, persistence/transformation mechanisms, Style framework
- Fiscal systems: Moderate tax collection efficiency supports fiscal capacity analysis
- Highland adaptation: Vertical archipelago coordination and labor-based systems demonstrate institutional capacity
- Ideas→Institutions: Educational systems and quipu networks enable knowledge transmission and institutional transformation
Notes
- Labor-Based Systems: Moderate tax collection efficiency (60%) indicates labor-based fiscal systems (mit'a) and administrative coordination
- Vertical Archipelago: Moderate-high territorial reach (1,000 km) with vertical archipelago coordination indicates highland adaptation and institutional capacity
- Legal Sophistication: Moderate legal code complexity (80-150 provisions) indicates legal sophistication and institutional development
- Quipu-Based Systems: Low literacy rates (3-5%) but quipu-based record-keeping indicates unique knowledge transmission systems
- Period variations:
- 500-900: Pre-Inca period, low-moderate level
- 900-1200: Pre-Inca period, moderate advancement
- 1200-1500: Inca period, continued advancement, peak period
- Regional variation: Core regions (Andean highlands) higher institutional capacity than periphery
- Data needs: More detailed regional institutional metrics, sectoral breakdown (administrative/legal/educational), institutional efficiency analysis
