Explanation:

The Inca empire was the largest empire in pre-Columbian America. The territory of the same was called Tawantinsuyu and the period of his rule is known, in addition, as incanato and / or incario. It flourished in the Andean region of the subcontinent between the fifteenth and sixteenth centuries, as a consequence of the apogee of the Inca civilization. It covered nearly two million square kilometers between the Pacific Ocean and the Amazon rainforest, from the vicinity of Pasto (Colombia) to the north to the Maule River (Chile) to the south.

The Incas considered their king, the Sapa Inca, as the "son of the sun". Many local forms of worship persisted in the empire, most of them related to the sacred local Huacas, but the Inca leaders encouraged the sun worship of Inti - their sun god - and imposed their sovereignty over other cults such as Pachamama

The Inca economy has been described in a contradictory way by scholars: as "feudal, slave, socialist (here one can choose between socialist paradise or socialist tyranny)". The Inca empire operated largely without money and without markets. Instead, the exchange of goods and services was based on reciprocity between individuals and between Inca individuals, groups and rulers. 'Taxes' consisted of a labor obligation of a person for the Empire. The Inca rulers (who theoretically possessed all means of production) corresponded by granting access to land and goods and providing food and drink in the celebrations of their subjects.

The Inca Empire encompassed the current territories corresponding to the southwestern end of Colombia on the border, passing through Ecuador, mainly through Peru, western Bolivia, the northern half of Chile and the north, northwest and west of Argentina.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
