Lake Titicaca Regional Polities

Timeline

1. c. 1000–1200Lake Titicaca basin · La Paz DepartmentAfter Tiwanaku's center collapsed, dispersed local power centers arose on the lakeshore and highlands, sustaining themselves on raised-field agriculture, llama herds, and cross-lake trade while continuing to invoke Tiwanaku ritual symbols.
2. 1311–1320Northern shore of Lake Titicaca (Lupaca region) · Puno RegionIn the early 14th century, lakeshore polities such as Lupaca and Colla each controlled terrace farming zones and salt-lake resources, sustaining alliances through local ritual centers; no single hegemon existed, presenting a landscape of multi-centric competition coexisting with marriage networks.
3. c. 1438–1470Around Lake Titicaca · La Paz DepartmentUnder Pachacuti and his successors, the Inca Empire gradually conquered the lakeshore polities and incorporated them into a four-tier administrative system; local elites were drawn into the Inca noble network, and the Tiwanaku heritage was reintegrated through sun worship and state rituals.
