Estonian vintage chocolate wrapper Kalev

The history of chocolate begins in Mesoamerica. Fermented beverages made from chocolate date back to 1900 BC.The Aztecs believed that cacao seeds were the gift of Quetzalcoatl, the god of wisdom, and the seeds once had so much value that they were used as a form of currency. Originally prepared only as a drink, chocolate was served as a bitter, frothy liquid, mixed with spices or corn puree. It was believed to have aphrodisiac powers and to give the drinker strength. Today, such drinks are also known as "Chilate" and are made by locals in the South of Mexico.

After its arrival to Europe in the sixteenth century, sugar was added to it and it became popular throughout society, first among the ruling classes and then among the common people. In the 20th century, chocolate was considered essential in the rations of United States soldiers at war. The word "chocolate" comes from the Classical Nahuatl word chocolātl, and entered the English language from the Spanish language.
