The Aztecs were a polytheistic civilization that worshipped many gods, with their main god being Huitzilopotchli. They believed Huitzilopotchli told them to settle where they did after seeing an eagle on a cactus with a snake in its mouth. The Aztecs practiced human sacrifice of defeated armies by removing and drying their hearts as an offering to the gods. They used two forms of currency - quachtli cloth and cocoa beans, with quachtli having more value. The Aztec empire was ruled from its capital of Tenochtitlan under the most powerful leader Huey Hatloni, though nobles were also consulted for some decisions. Tribute
