| Inca society was highly stratified. The emperor ruled with the aid of an aristocratic bureaucracy, exercising authority with harsh and often repressive controls. Inca technology and architecture were highly developed, although not strikingly original. Their irrigation systems, palaces, temples, and fortifications can still be seen throughout the Andes. The economy was based on agriculture, its staples being corn (maize), white and sweet potatoes, squash, tomatoes, peanuts (groundnuts), chili peppers, coca, cassava, and cotton. They raised guinea pigs, ducks, llamas, alpacas, and dogs. Clothing was made of llama wool and cotton. Houses were of stone or adobe mud. Practically every man was a farmer, producing his own food and clothing. |
