How did Inca state warehouses support the empire?

Inca state warehouses were essential to the empire's stability and logistical operations, serving as a strategic resource for managing the state's vast territory and diverse population.12

Functions of the Warehouses

• Resource Security: Warehouses were filled with food, such as processed tubers (chuño) and jerky (ch’arki), as well as textiles and other goods. These stores allowed the state to compensate for natural or man-made calamities, ensuring a food supply during adverse times.234
• Logistical Support: Strategically located along the more than 15,500 miles of the Inca highway system, these facilities provided necessary provisions for armies, priests traveling to shrines, and human or camelid porters.23
• State Operations: The warehouses supported state enterprises, such as large-scale corn production in the Cochabamba Valley, and supplied goods like textiles and corn beer to soldiers and laborers.13

Maintenance and Management

The filling and maintenance of these storehouses were key components of the mit’a system, a labor obligation where local groups provided energy for public works. These facilities were often built in locations that utilized environmental factors like wind and temperature to preserve goods for long periods.132
