The Postclassic Maya period, spanning from approximately 900 to 1500 CE, followed the Classic Maya civilization. During this time, the focus shifted from large city-states to smaller, more decentralized communities. Key sites included Chichen Itza and Tulum, which showcased a blend of architectural styles and cultural influences. Trade and warfare became increasingly important in Postclassic society, with Cacao and obsidian being significant trade goods. The period also saw the rise of new political entities and the decline of some Classic centers, leading to a dynamic cultural landscape characterized by adaptation and resilience.
