Maya Civilisation

The Maya civilisation developed the only fully functional writing system in pre-Columbian Mesoamerica and independently invented the concept of zero — a mathematical breakthrough unmatched by any other pre-contact American society. They created the most accurate calendar of the pre-modern world, achieving an error margin of just 0.0002 days per year, which is more precise than the Gregorian calendar's 0.0003 days per year, outperforming #2's timekeeping. At their peak, Maya cities like Tikal held around 100,000 inhabitants, comparable to the largest cities of medieval Europe. Their sophisticated astronomical observatories tracked celestial movements with an accuracy that rivals modern calculations, while hydraulic systems supported agriculture in challenging terrain. This record of achievements demonstrates an intellectual depth that, despite lacking draft animals or iron, placed them among the most advanced pre-modern societies globally.
