Born Cusi Yupanqui, he adopted a title translating to "Earth-shaker" after successfully defending Cusco and transforming the Inca from a kingdom into a vast empire.

Unlike a fortress or public city, this secluded 15th-century mountain retreat was built strictly for Pachacuti and his royal lineage to relax, hunt, and worship.

By claiming direct descent from Inti, Pachacuti established himself as a living god, centralizing spiritual and political power to solidify his absolute authority.

This forced resettlement system, called the mitma, separated newly conquered groups and moved them into deeply loyal Inca territories to dissolve their political power.
