Chichen ItzaRendered in Spanish as Chichén Itzá and traditional Yucatec Maya as Chichen Itza , , often with the emphasis reversed in English to ; from () "at the mouth of the well of the Itza people" was a large pre-Columbian city built by the Maya people of the Terminal Classic period. The archeological site is located in Tinúm Municipality, Yucatán, Mexico, between the cities of Valladolid and Mérida.Gobierno del Estado de Yucatán 2007.

Chichen Itza was a major focal point in the Northern Maya Lowlands from the Late Classic ( 600–900 AD) through the Terminal Classic ( 800–900 AD) and into the early portion of the Postclassic period ( 900–1200 AD). 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.

Chichen Itza was one of the largest Maya cities and it was likely to have been one of the mythical great cities, or Tollans, referred to in later Mesoamerican literature. The city may have had the most diverse population in the Maya world, a factor that could have contributed to the variety of architectural styles at the site.

The ruins of Chichen Itza are federal property, and the site's stewardship is maintained by Mexico's Instituto Nacional de Antropología e Historia (National Institute of Anthropology and History, INAH). The land under the monuments had been privately owned until 29 March 2010, when it was purchased by the state of Yucatán.Concerning the legal basis of the ownership of Chichen and other sites of patrimony, see Breglia (2006), in particular Chapter 3, "Chichen Itza, a Century of Privatization".

Chichen Itza is one of the most visited archeological sites in Mexico, with over 2.6 million tourists in 2017.

Name and orthography

The Maya name "Chichén Itzá" means "At the mouth of the well of the Itzá". This derives from chi, meaning "mouth" or "edge", and chʼen or chʼeʼen, meaning "well". Itzá is the name of an ethnic-lineage group that gained political and economic dominance of the northern peninsula. One possible translation for Itzá is "enchanter (or enchantment) of the water", from its (itz), "sorcerer", and ha, "water".

The name is spelled in Spanish, and the accents are sometimes maintained in other languages to show that both parts of the name are stressed on their final syllable. Other references prefer the modern Maya orthography, Chichʼen Itzaʼ (pronounced ). This form preserves the phonemic distinction between chʼ and ch, since the base word chʼeʼen (which, however, is not stressed in Maya) begins with a postalveolar ejective affricate consonant. Traditional Yucatec Maya spelling in Latin letters, used from the 16th through mid 20th century, spelled it as "Chichen Itza" (as accents on the last syllable are usual for the language, they are not indicated as they are in Spanish). The word "Itzaʼ" has a high tone on the "a" followed by a glottal stop (indicated by the apostrophe).

Evidence in the Chilam Balam books indicates another, earlier name for this city prior to the arrival of the Itza hegemony in northern Yucatán. While most sources agree the first word means seven, there is considerable debate as to the correct translation of the rest. This earlier name is difficult to define because of the absence of a single standard of orthography, but it is represented variously as Uuc Yabnal ("Seven Great House"), Uuc Hab Nal ("Seven Bushy Places"), Uucyabnal ("Seven Great Rulers") or Uc Abnal ("Seven Lines of Abnal").Uuc Yabnal becomes Uc Abnal, meaning the "Seven Abnals" or "Seven Lines of Abnal" where Abnal is a family name, according to Ralph L. Roys (). This name, dating to the Late Classic Period, is recorded both in the book of Chilam Balam de Chumayel and in hieroglyphic texts in the ruins.

Location

Chichen Itza is located in the eastern portion of the Mexican state of Yucatán. The northern Yucatán Peninsula is karst, and the rivers in the interior all run underground. There are four visible, natural sink holes, called cenotes, that could have provided plentiful water year round at Chichén, making it attractive for settlement. Of these cenotes, the "Cenote Sagrado" or "Sacred Cenote" (also variously known as the Sacred Well or Well of Sacrifice), is the most famous. In 2015, scientists determined that there is a hidden cenote under the Temple of Kukulkan, which has never been seen by archeologists.

Geologically, the site's hydrologic network is connected to the broader Ring of Cenotes, a semicircular alignment of sinkholes formed along the buried rim of the Chicxulub impact crater, which facilitated the accumulation of accessible freshwater reservoirs across the dry limestone plain.

According to post-Conquest sources (Maya and Spanish), pre-Columbian Maya sacrificed objects and human beings into the cenote as a form of worship to the Maya rain god Chaac. Edward Herbert Thompson dredged the Cenote Sagrado from 1904 to 1910, and recovered artifacts of gold, jade, pottery and incense, as well as human remains. A study of human remains taken from the Cenote Sagrado found that they had wounds consistent with human sacrifice.

Hydrogeochemistry The settlement and urban expansion of Chichen Itza were fundamentally governed by the localized hydrogeochemistry of the northern Yucatán Peninsula karst plain. Lacking surface rivers, the city relied entirely on structural access to the regional phreatic aquifer, where meteoric dissolution of the Tertiary limestone cap created deep collapse sinkholes (cenotes) exposing the underlying freshwater lens.

Chicxulub Boundary Alignment: The subterranean hydrologic network connecting the Cenote Sagrado, Xtoloc, and Holtún cenotes is structurally aligned with the high-permeability breccia fractures of the buried Chicxulub crater rim, which directs regional groundwater flow toward the northern coast. Halocline Stratification: The deep water table beneath the site core exhibits a distinct density stratification, featuring a upper freshwater lens floating above an intrusive marine saline wedge, a geochemical boundary that preserved organic artifacts thrown into the cenotes from rapid oxidation. Sub-Pyramid Sinkhole Connectivity: Geophysical electrical resistivity tomography (ERT-3D) confirmed that the sub-surface void underlying the Temple of Kukulcán forms a subterranean hydrologic node intersecting the north-south alignment of the site's primary open cenotes.

Political organization

Several archeologists in the late 1980s suggested that unlike previous Maya polities of the Early Classic, Chichen Itza may not have been governed by an individual ruler or a single dynastic lineage. Instead, the city's political organization could have been structured by a "multepal" system, which is characterized as rulership through council composed of members of elite ruling lineages.;

This theory was popular in the 1990s, but in recent years, the research that supported the concept of the "multepal" system has been called into question, if not discredited. The current belief trend in Maya scholarship is toward the more traditional model of the Maya kingdoms of the Classic Period southern lowlands in Mexico.

Economy Chichen Itza was a major economic power in the northern Maya lowlands during its apogee. Participating in the water-borne circum-peninsular trade route through its port site of Isla Cerritos on the north coast, Chichen Itza was able to obtain locally unavailable resources from distant areas such as obsidian from central Mexico and gold from southern Central America.

Between 900 and 1050 AD Chichen Itza expanded to become a powerful regional capital controlling north and central Yucatán. It established Isla Cerritos as a trading port, which, along with the another Northern Yucatan port Vista Alegre, acted as the main centers of a complex maritime market system dominated by Chichen Itza. However, such trading settlements remained relatively small throughout their use and none exceeded 300m in length, as most of these sites were built on small Islands near the coast.

Tribute and subsequent distribution of such goods was another important aspect of Chichen Itza's economy. High value wealth goods were extracted from cities it conquered militarily, in the context of its rise to power during Classic Maya Collapse.

History

The layout of Chichen Itza's core developed during its earlier phase of occupation, between 750 and 900 AD. Its final layout was developed after 900 AD, and the 10th century saw the rise of the city as a regional capital controlling the area from central Yucatán to the north coast, with its power extending down the east and west coasts of the peninsula. The earliest hieroglyphic date discovered at Chichen Itza is equivalent to 832 AD, while the last known date was recorded in the Osario temple in 998.

Establishment The Late Classic city was centered upon the area to the southwest of the Xtoloc cenote, with the main architecture represented by the substructures now underlying the Las Monjas and Observatorio and the basal platform upon which they were built. While the city was founded by the local Mayans of Northern Yucatan, another group of Mayan people of debated origins, the Itza, started arriving around 800 AD and gradually established themselves in the region. The name Itza was given by the local people, meaning "those who speak our language brokenly", and is considered to be part of the namesake of Chichen Itza.

Ascendancy Chichen Itza rose to regional prominence toward the end of the Early Classic period (roughly 600 AD). It was, however, toward the end of the Late Classic and into the early part of the Terminal Classic that the site became a major regional capital, 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.

As Chichen Itza rose to prominence, the cities of Yaxuna (to the south) and Coba (to the east) were suffering decline. These two cities had been mutual allies, with Yaxuna dependent upon Coba. At some point in the 10th century Coba lost a significant portion of its territory, isolating Yaxuna, and Chichen Itza may have directly contributed to the collapse of both cities.

Decline

According to some colonial Maya sources (e.g., the Book of Chilam Balam of Chumayel), Hunac Ceel, ruler of Mayapan, conquered Chichen Itza in the 13th century. Hunac Ceel supposedly prophesied his own rise to power. According to custom at the time, individuals thrown into the Cenote Sagrado were believed to have the power of prophecy if they survived. During one such ceremony, the chronicles state, there were no survivors, so Hunac Ceel leaped into the Cenote Sagrado, and when removed, prophesied his own ascension.

While there is some archeological evidence that indicates Chichen Itza was at one time looted and sacked, there appears to be greater evidence that it could not have been by Mayapan, at least not when Chichen Itza was an active urban center. Archeological data now indicates that Chichen Itza declined as a regional center by 1100, before the rise of Mayapan. Ongoing research at the site of Mayapan may help resolve this chronological conundrum.
