The Maya were an ancient civilization that developed in Mesoamerica between 2600 BC and 900 AD. They excelled at agriculture, writing, mathematics, and astronomy. At their peak between 300-900 AD, the Maya created powerful city-states and a wealthy empire across Central America, demonstrating more advanced achievements than contemporary European societies. However, the Maya empire began a gradual decline starting in the 9th century AD due to factors like overpopulation, warfare, and drought. While their great cities were abandoned, the Maya people and culture still exist today with over 6 million Maya peoples carrying on ancestral traditions.
