The Inca Empire: Foundation and Expansion

Origins of the Inca Civilization

  • Timeline: Inca Empire flourished 1438-1533 CE
  • Geographic Extent: Stretched 2,500 miles along Andes Mountains
  • Population: Estimated 12-15 million people at peak

  • Capital: Cusco, "Navel of the World" in Quechua

Key Inca Rulers

  • Manco Capac (c. 1200): Legendary founder of Inca dynasty
  • Pachacuti (1438-1471): Empire builder, likely ordered Machu Picchu construction
  • Tupac Inca Yupanqui (1471-1493): Expanded empire significantly
  • Huayna Capac (1493-1525): Last great Inca ruler before Spanish arrival
  • Atahualpa (1532-1533): Final Inca emperor, executed by Spanish

Oral Tradition

The Incas had no written language, relying instead on oral tradition and quipu (knotted string records) for communication and record-keeping. This makes archaeological evidence at sites like Machu Picchu even more valuable for understanding their civilization.
