The Maya civilization flourished in Mesoamerica from around 2000 BCE to 1500 CE. They developed advanced cities and a complex written language in southern Mexico and parts of Central America. At its peak during the Classic Period from 300-900 CE, Mayan civilization consisted of independent city-states like Tikal and Copan, with rulers acting as god-kings over a stratified society. Around 900 CE, many Maya cities were mysteriously abandoned, though some continued in the northern Yucatan Peninsula into the Post-Classic period until the arrival of Europeans.
