The Olmec civilization, located in ancient Mexico, prospered in Pre-Classical (Formative) Mesoamerica from c. 1200 BCE to c. 400 BCE. Monumental sacred complexes, massive stone sculptures, ball games, the drinking of chocolate, and animal gods were all features of Olmec culture passed on to those peoples who followed this first great Mesoamerican civilization.

With their heartlands in the Gulf of Mexico (now the states of Veracruz and Tabasco), Olmec influence and trade activity spread from 1200 BCE, even reaching as far south as present-day Nicaragua. Many Olmec sites suffered systematic and deliberate destruction of their monuments sometime between 400 and 300 BCE.

The Olmec civilization presents something of a mystery, indeed, we do not even know what they called themselves, as Olmec was their Aztec name and meant 'rubber people'. Due to a lack of archaeological evidence their ethnic origins and the location and extent of many of their settlements are not known. The Olmecs did, however, codify and record their gods and religious practices using symbols. The precise significance of this record is much debated but, at the very least, its complexity does suggest some sort of organised religion involving a priesthood. The Olmec religious practices of sacrifice, cave rituals, pilgrimages, offerings, ball-courts, pyramids and a seeming awe of mirrors, was also passed on to all subsequent civilizations in Mesoamerica until the Spanish Conquest in the 16th century CE.
