Inca:
The Incas lived from approximately 3,000 BC to 1,533 BC, with more coverage in Peru, as well as influencing territories in northern Chile, Bolivia and Ecuador in the regions dominated by the Andes.
Although ancient, Inca society developed more strongly from the twelfth century, encompassing a series of peoples in the course of a long process. In the fourteenth century, at its height, there were under the Inca power about 20 million people in the territories mentioned above. This power was centered on the figure of a sovereign, called Inca ("the son of the sun"), who was considered almost a god.
Aztec:
They were an indigenous people belonging to the Nahua group and were also called Mexicas (hence Mexico). The Aztecs founded their largest city, Tenochtitlan, in the year 1325, and it was built on an island in a Mexican lake called Texcoco. They gradually conquered the rest of the area, until in 1521 the territory was taken over by Spanish invaders.
The Aztecs reached a high degree of technological and cultural development, organizing themselves in diverse social classes, such as nobles, priests, warriors, merchants and slaves. They possessed a pictographic writing and two calendars (astronomical and liturgical). However, although they were not as advanced as the Incas, they had a 365-day calendar and also wore hieroglyphs.
