The history of chocolate began in Mesoamerica. Chocolate, the fermented, roasted, and ground beans of the Theobroma cacao, can be traced to the Mokaya and other pre-Olmec people, with evidence of cocoa beverages dating back to 1900 BC.
Chocolate played a special role in both Mayan and Aztec royal and religious events. Priests presented cocoa beans as offerings to the gods and served cocoa drinks during sacred ceremonies. All of the areas that were conquered by the Aztecs that grew cocoa beans were ordered to pay them as a tax, or as the Aztecs called it, a "tribute".
