4. They Used Chocolate As Money
Mayan society was initially a barter economy, where people exchanged goods with each other without using a common currency. However, in the peak Mayan period (250 to 900 CE), they used cacao beans (from which chocolate is made) as money to buy goods and services!
This is because cacao was a prized possession amongst the Mayans, who considered it to be a gift from the Gods. They also frequently used it for special religious rituals.
