Both the Incas and Aztecs believed in and worshipped the sun god. Human sacrifices were both practiced and participated in by them. And they had constructed big temples in which to perform the sacrifices, as well as specific temples in which to worship their god. The Incas and Aztecs practiced polytheism, which meant they believed in more than one god. Aztecs were ruled by an Emperor whose main purpose was to lead in the wars. The Aztecs required local rulers and conquered populations to pay a levy. Sapa Inca, the ruler with total power, ruled Inca. This emperor was also the religious head of the empire.
