Chichen Itza is a large pre-Columbian archaeological site built by the Maya civilization located in the northern center of the Yucatán Peninsula, in the Yucatán state, present-day Mexico.
Chichen Itza was a major regional center in the northern Maya lowlands from the Late Classic through the Terminal Classic and into the early portion of the Early Postclassic period. The site exhibits a multitude of architectural styles, from what is called "Mexicanized" and reminiscent of styles seen in central Mexico to the Puuc style found among the Puuc Maya of the northern 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.
Archaeological data, such as evidence of burning at a number of important structures and architectural complexes, suggest that Chichen Itza's collapse was violent. Following the decline of Chichen Itza's hegemony, regional power in the Yucatán shifted to a new center at Mayapan.
The ruins of Chichen Itza are federal property, and the site's stewardship is maintained by Mexico's National Institute of Anthropology and History (Instituto Nacional de Antropología e Historia, INAH). The land under the monuments, however, is privately-owned by the Barbachano family.
Chichen Itza rose to regional prominence towards the end of the Early Classic period (or, roughly 600 AD). It was, however, towards the end of the Late Classic and into the early part of the Terminal Classic that the site became a major regional capitol, centralizing and dominating political, sociocultural, economic, and ideological life in the northern Maya lowlands. The ascension of Chichen Itza roughly correlates with the decline and fragmentation of the major centers of the southern Maya lowlands, such as Tikal.
Some ethnohistoric sources claim that in about 987 a Toltec king named Quetzalcoatl arrived here with an army from central Mexico, and (with local Maya allies) made Chichen Itza his capital, and a second Tula. The art and architecture from this period shows an interesting mix of Maya and Toltec styles. However, the recent re-dating of Chichen Itza's decline indicates that Chichen Itza is largely a Late/Terminal Classic site, while Tula remains an Early Postclassic site (thus reversing the direction of possible influence).
