The Olmec and Mayan civilizations both exhibited significant cultural continuities, including the construction of monumental architecture and the development of complex religious beliefs centered around nature and agrarian deities. Politically, the Olmec established one of the earliest known hierarchical societies in Mesoamerica, while the Mayans expanded this with a more intricate system of city-states, each with its own ruler, which allowed for varying degrees of political autonomy. Technologically, both civilizations advanced in astronomy and mathematics, with the Maya significantly improving these fields, culminating in the creation of a sophisticated calendar system. Economically, both relied on agriculture, particularly maize cultivation, but the Mayans developed a more extensive trade network, exchanging goods like cacao and jade across Mesoamerica. Despite their differences, both cultures contributed foundational elements that influenced future Mesoamerican societies.
