INCA'S LAW.

The Incas were a great imperial state that raised in the Andean highlands and extended their control over some 3,000 miles. Despite the beauty of its landscapes, life in the highlands and the dry and over the sandy soil of the Coast line is pretty much very hard. Water is a scarce resource, which is accessed by seasons and the rugged terrain makes agriculture a very hard work.
For the inhabitants of the Inca Empire, the execution of the divine law that controlled the Water and the Land were beyond their power, they needed to submit themselves to the divine entities in charge of it. The Incas sought to expand agricultural areas, continuing building terraces complemented by very complex irrigation systems.
Because of their belief based on two elements Water and Earth, they understood that the origin of two elements were in the cosmos governed by a divine Law. Then they incorporated laws of previous Andean cultures, and fused them together and applied them in new and harmonic ways.
The state organization was superb in controlling peoples of different cultures and languages achieving a level of integration and domination never achieved before in the highlands of South America.
Rather than the breakdown of power that took place in many cultures around the World, in the Andean zone a number of large states continued to be important. Some states were in the Andean highlands on the broad open areas near Lake Titicaca, and other states were along rivers on the North Coast. They remained as centers of agricultural activity and population density. Of these states the coastal kingdom of Chimu, centered on its capital of Chan Chan, emerged as the most powerful. It gained control of most of the North Coast of Peru.
The Inca Law based on a set of powerful divine beliefs, customs and practices was very powerful.
The Inca imposed a set of 3 Laws on its citizens to maintain a level of morality on a very disciplined society: "Ama Sua, Ama Llulla, Ama Quella," or "Do not steal, Do not lie, Do not be lazy."
The Law promoted peace among its citizens, and the level of crime was very low. There was no system of imprisonment, and when a crime was committed the punishment was ruthless.
Since the purpose of the Law was to teach a lesson to the offender and prevent re-occurrence by any member of the society, mutilation and death penalty were applied as a exemplary to the rest of the population. Those who survived a punishment were forced to tell their experience for the rest of their lives and those interested in listening would give them food so basically their survival was based on how engaging and compelling their stories were.
The Inca Law then was very severe since it was understood as a kind of tool that regulated the divine cosmic energy of the 2 elements Water and Earth and the harmony between them was the mission they had to accomplish during its time on Earth. Any kind of law transgression was considered an action against divinities and penalties were collective or personal, according to the level of crime, from simple mass repressions to the isolation of entire villages.
Rebellions, homicide, adultery, second offenses in drunkenness, theft, and laziness, were all punished to death by stoning, hanging, or pushing the person off the cliff. Mutilations were common for theft.
When the Incas conquered a new territory local law  and rules continued to be applied since they had a divine origin and the supernatural entities in control were respected unless they were in conflict with the Inca Law. If the leader of the newly conquered territory opposed the new divine set of rules, he would be executed and a new loyal leader were elected to oversee and secure loyalty among the population. This new leader was usually transferred from another territory along with his family and entourage.
The world view of the Incas were reflected in its concern for food security meaning that the social organization of the empire was aimed at productivity and expanding borders to earn higher definition of power in their farmlands. Since their spiritual world was based on duality and reciprocity they maintained a fusion of power between the two in which harmony was the major ingredient.
