Pre-colonial

The region now known as Bolivia had been occupied for over 2,500 years when the Aymara arrived; however, present-day Aymara associate themselves with the ancient civilization of the Tiwanaku Empire, which had its capital at Tiwanaku, in Western Bolivia. The capital city of Tiwanaku dates-back as early as 1500 BC, when it was a small, agriculturally-based village.

The Aymara community grew to urban proportions between AD 600 and AD 800, becoming an important regional power in the southern Andes. According to early estimates, the city covered approximately 6.5 square kilometers (2.5 square miles) at its peak, and had between 15,000 and 30,000 inhabitants. However, in 1996, satellite imaging was used to map the extent of preserved suka kollus (flooded raised fields) across the three primary valleys of Tiwanaku, with the results suggesting a population-carrying capacity of anywhere between 285,000 and 1,482,000 people.

Around AD 400, Tiwanaku went from being a locally-dominant force to a 'predatory' state, aggressively expanding its reach into the Yungas and bringing its culture and ways to new peoples in Peru, Bolivia, and Chile. Nonetheless, Tiwanaku was not a violent or domineering culture; to expand its reach, the state exercised great political astuteness, created colonies, fostered local trade agreements (which made other cultures rather dependent), and instituted state cults.

As rainfall gradually decreased, the stores of food supplies decreased, and thus the elites lost power. Tiwanaku disappeared around AD 1000. The area remained uninhabited for centuries thereafter.

Between 1438 and 1527, Incan Empire expanded from its capital at Cusco, gaining control over much of what is now the Bolivian Andes, and extending its control into the fringes of the Amazon basin.
L'empire Tiwanaku

L'empire Tiwanaku était basé dans l'ouest de la Bolivie et s'étendait dans l'actuel Pérou et Chili de 300 à 1000 après J.-C. Tiwanaku est reconnu par les spécialistes andins comme l'une des civilisations sud-américaines les plus importantes avant l'émergence de l'empire Inca au Pérou ; il fut la capitale rituelle et administrative d'une puissance étatique majeure pendant environ cinq cents ans. Les ruines de cette cité-État antique se trouvent près de la rive sud-est du lac Titicaca, dans la municipalité de Tiwanaku, la province d'Ingavi, le département de La Paz, à environ 72 kilomètres (45 miles) à l'ouest de La Paz.

### Draft ###

### 1. Query Parsing

User asks: "Je travaille sur l'histoire pré-coloniale de la Bolivie" → pre-colonial Bolivian history research context.

Key claim: "l'empire Tiwanaku aurait décliné vers l'an 1000" → Tiwanaku Empire declined ~1000 CE.

Seeks confirmation. "Exact chronologie" suggests need for precision verification.

? Potential issues:
- Dating methodology variations
- Regional vs central site dating discrepancies  
- "Exact" vs "approximate" tension in archaeological dating

### 2. Domain Contextualization

Tiwanaku Empire ● high confidence archaeological site, western Bolivia.
Timeline: ~500 BCE - ~1000 CE (Classic period 400-1000 CE)
Geographic: Lake Titicaca basin, extending Peru/Chile
Pre-Incaic Andean civilization

Dating methods:
├─ Radiocarbon dating
├─ Ceramic sequence analysis  
└─ Environmental proxy records

### 3. Chronological Verification

Standard academic consensus ●:
- Empire peak: 600-800 CE
- Decline phase: 900-1000 CE  
- Complete abandonment: ~1000-1100 CE

∴ User's date (1000 CE) ≈ accurate within archaeological precision limits.

⟨H≈0.8⟩ *But what makes civilizations fall? Lake Titicaca shores, ancient power centers, ritual sites carved from stone. The empire that built Puma Punku, Kalasasaya. Elites controlling agricultural surplus, ceremonial centers dominating the southern Andes. Then climate shifts, decreased rainfall, agricultural stress, the slow collapse of complex society...*

### 4. Supporting Evidence Triangulation

Environmental indicators ●:
- Decreased precipitation patterns
- Agricultural carrying capacity reduction
- Resource depletion pressures

Archaeological indicators ●:
- Reduced ceremonial activity
- Abandonment of administrative centers  
- Population exodus/decline

※ Key insight: Gradual process, not single catastrophic event

### 5. Response Construction

Confirmation: 1000 CE date ● accurate.

Context expansion:
- 2,500+ year occupation (user mentioned notes dating to 1500 BCE)
- Tiwanaku as major pre-Incaic power
- Geographic scope: Bolivia + Peru/Chile regions
- 500-year duration (user's 300-1000 CE range correct)

Causal explanation: Environmental degradation → agricultural stress → elite power loss → civilization collapse.

Uncertainty acknowledgment: "environ" indicates approximate nature of dating.

Final verification: ◐ User's "exact" request met with appropriately nuanced response.

### Answer###
Oui, votre chronologie est exacte. L'empire Tiwanaku a effectivement décliné vers l'an 1000. Cette civilisation andine, basée dans l'ouest de la Bolivie et s'étendant dans l'actuel Pérou et Chili, a représenté l'une des civilisations sud-américaines les plus importantes avant l'émergence de l'empire Inca.

L'empire Tiwanaku a eu une durée remarquable d'environ cinq cents ans, avec une période de puissance maximale entre 600 et 800 après J.-C. Sa capitale, Tiwanaku, était un centre urbain important qui s'étendait sur environ 6,5 kilomètres carrés à son apogée, avec une population estimée entre 15 000 et 30 000 habitants selon les premières estimations, ou même entre 285 000 et 1 482 000 habitants selon des études plus récentes utilisant l'imagerie satellitaire pour cartographier les champs agricoles submergés.

Le déclin de Tiwanaku vers 1000 après J.-C. s'explique par plusieurs facteurs, notamment la diminution progressive des précipitations qui a entraîné une réduction des stocks de provisions alimentaires et, par conséquent, une perte de pouvoir des élites dirigeantes. Après cette disparition, la région resta inhabitée pendant plusieurs siècles.
