William Hickling Prescott,
History of the Conquest of Peru
“ The ultimate aim of its institutions was domestic quiet. But it seemed as if this were to be obtained only by foreign war. Tranquillity in the heart of the monarchy, and war on its borders, was the condition of Peru. By this war it gave occupation to a part of its people, and, by the reduction and civilization of its barbarous neighbors, gave security to all. Every Inca sovereign, however mild and benevolent in his domestic rule, was a warrior, and led his armies in person. Each successive reign extended still wider the boundaries of the empire. ”
