The Inca Empire

Key Questions Answered

• •Split Inheritance System: The Inca rule of passing political power to one heir while distributing material wealth to the deceased ruler's descendants created a structural obligation forcing each new emperor to fund his reign through continuous territorial conquest and expansion.
• •Labor-Based Economy: The Inca operated the only known major civilization without currency or market economy, using the Mit'a system where citizens paid annual labor quotas to the state for infrastructure projects like road building, replacing monetary taxation entirely with coordinated human effort.
• •Khipu Record-Keeping: Without any written script, the Inca encoded census, trade, and labor data using colored cotton threads tied in directional knots forming a decimal system called khipu, enabling administration of the largest pre-Columbian civilization purely through tactile, portable data storage.
• •Tambo Relay Network: The Inca maintained approximately 2,500 rest stations called tambos spaced one day's journey apart across their road network, enabling trained runners called Choscis to relay official orders and goods across the entire empire with speed sufficient for centralized governance.
