The Maya civilization, known for its hieroglyphic script, art, architecture, mathematics, and astronomical knowledge, flourished in modern-day southeastern Mexico, Guatemala, Belize, El Salvador, and western Honduras from around 2000 BC to 900 AD. Their culture varied greatly across regions, but was unified by common religious beliefs and practices. Their civilization made a notable impact on the development of Mesoamerican societies, with their writing system and calendar adopted by other civilizations like the Aztecs. Despite their decline from the 10th century onwards, the Maya civilization’s legacy as one of the most advanced civilizations in pre-Columbian Americas continues to this day.
