Chichen Itza was a large pre-Columbian city built by the Maya people of the Post Classic. The archaeological site is located in the municipality of Tinum, in the Mexican state of Yucatán.
Chichen Itza was a major focal point in the northern Maya lowlands from the Late Classic (c. AD 600–900) through the Terminal Classic (c.AD 800–900) and into the early portion of the Early Postclassic period (c. AD 900–1200). The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the Puuc and Chenes styles of the northern Maya lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion.
