The Mayan civilization emerged in the Yucatán Peninsula around 2000 BCE. Starting as nomadic hunter-gatherers, they gradually settled into agricultural communities, developing complex societies with social hierarchies, specialized crafts, and trade networks. The Olmec civilization heavily influenced early Mayan culture. By the end of the Preclassic period, large urban centers with monumental architecture had emerged. Mayan society was hierarchical, with divine kings ruling independent city-states. Religion played a central role, with elaborate rituals and beliefs tied to astronomical events and cyclical time concepts.
