The term Olmec refers to the ancient civilization that existed in the region of present-day Mexico, particularly in the Gulf Coast, during the Pre-Columbian era. The name Olmec is derived from the Aztec words "olli" meaning "rubber" and "mecatl" meaning "country" or "place". The Olmecs were known for their advanced culture and their extensive use of rubber in various aspects of their society.
