In the history of the Americas , the pre-Columbian era , also known as the pre-contact era , or as the pre-Cabraline era specifically in Brazil , spans from the initial peopling of the Americas in the Upper Paleolithic to the onset of European colonization , which began with Christopher Columbus 's voyage in 1492. This era encompasses the history of Indigenous cultures prior to significant European influence, which in some cases did not occur until decades or even centuries after Columbus's arrival.
134-755: Chichén Itzá (often spelled Chichen Itza in English and traditional Yucatec Maya) Yucatec Maya pronunciation 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 State , Mexico . Chichén Itzá was a major focal point in the Northern Maya Lowlands from the Late Classic (c. AD 600–900) through
268-499: 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
402-471: A battle scene. Pre-Columbian During the pre-Columbian era, many civilizations developed permanent settlements, cities, agricultural practices, civic and monumental architecture, major earthworks , and complex societal hierarchies. Some of these civilizations had declined by the time of the establishment of the first permanent European colonies, around the late 16th to early 17th centuries, and are known primarily through archaeological research of
536-449: A cavern dive into a cave dive. Contrary to cenote cavern diving, cenote cave diving requires special equipment and training (certification for cave diving). However, both cavern and cave diving require detailed briefings, diving experience, and weight adjustment to freshwater buoyancy. The cenotes are usually filled with rather cool fresh water. Cenote divers must be wary of possible halocline ; this produces blurred vision until they reach
670-591: A different social structure. Until the accurate dating of Watson Brake and similar sites, the oldest mound complex was thought to be Poverty Point , also located in the Lower Mississippi Valley . Built about 1500 BCE, it is the centerpiece of a culture extending over 100 sites on both sides of the Mississippi . The Poverty Point site has earthworks in the form of six concentric half-circles, divided by radial aisles, together with some mounds. The entire complex

Chichén Itzá entered the popular imagination in 1843 with the book Incidents of Travel in Yucatan by John Lloyd Stephens (with illustrations by Frederick Catherwood ). The book recounted Stephens' visit to Yucatán and his tour of Maya cities, including Chichén Itzá. The book prompted other explorations of
938-416: A list of the longest and deepest water-filled and dry caves within the state boundaries. When cavern diving, one must be able to see natural light the entire time that one is exploring the cavern (e.g., Kukulkan cenote near Tulum , Mexico). During a cave dive, one passes the point where daylight can penetrate, and one follows a safety guideline to exit the cave. Things change quite dramatically once moving from

The layout of Chichén Itzá site 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
1340-558: A regional center by 1100, before the rise of Mayapan. Ongoing research at the site of Mayapan may help resolve this chronological conundrum. After Chichén Itzá elite activities ceased, the city may not have been abandoned. When the Spanish arrived, they found a thriving local population, although it is not clear from Spanish sources if these Maya were living in Chichen Itza proper, or a nearby settlement. The relatively high population density in
1474-529: A rock overhanging above the water. The stereotypical cenotes often resemble small circular ponds , measuring some tens of meters in diameter with sheer rock walls. Most cenotes, however, require some degree of stooping or crawling to access the water. In the north and northwest of the Yucatán Peninsula in Mexico, the cenotes generally overlie vertical voids penetrating 50 to 100 m (160 to 330 ft) below

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
2010-520: A single unified empire. The Mixtecs would eventually be conquered by the Aztecs until the Spanish conquest. The Mixtecs saw the Spanish conquest as an opportunity for liberation and established agreements with the conquistadors that allowed them to preserve their cultural traditions, though relatively few sections resisted Spanish rule. The Totonac civilization was concentrated in the present-day states of Veracruz and Puebla . The Totonacs were responsible for
2144-483: A statue of a figure on its back, knees drawn up, upper torso raised on its elbows with a plate on its stomach. Augustus Le Plongeon called it "Chaacmol" (later renamed " Chac Mool ", which has been the term to describe all types of this statuary found in Mesoamerica). Teobert Maler and Alfred Maudslay explored Chichén in the 1880s and both spent several weeks at the site and took extensive photographs. Maudslay published
2278-412: A vast coastal aquifer system, which is typically density-stratified. The infiltrating meteoric water (i.e., rainwater) floats on top of higher- density saline water intruding from the coastal margins. The whole aquifer is therefore an anchialine system (one that is land-locked but connected to an ocean).

In 1936, a simple morphometry-based classification system for cenotes was presented. The classification scheme was based on morphometric observations above the water table, and therefore incompletely reflects

The first is the short chronology theory with the first movement beyond Alaska into the Americas occurring no earlier than 14,000–17,000 years ago, followed by successive waves of immigrants. The second belief is the long chronology theory , which proposes that the first group of people entered the hemisphere at a much earlier date, possibly 50,000–40,000 years ago or earlier. Artifacts have been found in both North and South America which have been dated to 14,000 years ago, and accordingly humans have been proposed to have reached Cape Horn at

Mound building was continued by succeeding cultures, who built numerous sites in the middle Mississippi and Ohio River valleys as well, adding effigy mounds , conical and ridge mounds, and other shapes. The Woodland period of North American pre-Columbian cultures lasted from roughly 1000 BCE to 1000 CE. The term was coined in the 1930s and refers to prehistoric sites between

Throughout thousands of years, paleo-Indian people domesticated, bred, and cultivated many plant species, including crops that now constitute 50–60% of worldwide agriculture. In general, Arctic, Subarctic, and coastal peoples continued to live as hunters and gatherers, while agriculture

Pre-Olmec civilization began with the production of pottery in abundance, around 2300 BCE in the Grijalva River delta. Between 1600 and 1500 BCE, the Olmec civilization had begun, with the consolidation of power at their capital, a site today known as San Lorenzo Tenochtitlán near

Chichén Itzá 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 AD 900 and 1050 Chichén Itzá expanded to become

Genetic evidence found in Indigenous peoples ' maternally inherited mitochondrial DNA (mtDNA) supports the theory of multiple genetic populations migrating from Asia. After crossing the land bridge, they moved southward along the Pacific coast and through an interior ice-free corridor. Throughout millennia, Paleo-Indians spread throughout
3618-594: The Archaic Period , numerous archaeological cultures have been identified. The unstable climate led to widespread migration, with early Paleo-Indians soon spreading throughout the Americas, diversifying into many hundreds of culturally distinct tribes. The Paleo-Indians were hunter-gatherers , likely characterized by small, mobile bands consisting of approximately 20 to 50 members of an extended family. These groups moved from place to place as preferred resources were depleted and new supplies were sought. During much of

The Adena culture and the ensuing Hopewell tradition during this period built monumental earthwork architecture and established continent-spanning trade and exchange networks. This period is considered a developmental stage without any massive changes in a short period but instead has a continuous development in stone and bone tools, leatherworking, textile manufacture, tool production, cultivation, and shelter construction. Some Woodland people continued to use spears and atlatls until
3886-665: 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"). This name, dating to

The Zapotecs were a civilization that thrived in the Oaxaca Valley from the late 6th century BCE until their downfall at the hands of the Spanish conquistadors. The city of Monte Albán was an important religious center for the Zapotecs and served as the capital of

Cenotes have attracted cavern and cave divers, and there are organized efforts to explore and map these underwater systems. They are public or private and sometimes considered "National Natural Parks". Great care should be taken to avoid spoiling this fragile ecosystem when diving. In Mexico, the Quintana Roo Speleological Survey maintains

In 2015, scientists determined that there is a hidden cenote under the Temple of Kukulkan , which has never been seen by archeologists. 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

For instance, the Maya civilization maintained written records, which were often destroyed by Christian Europeans such as Diego de Landa , who viewed them as pagan but sought to preserve native histories. Despite the destruction, a few original documents have survived, and others were transcribed or translated into Spanish, providing modern historians with valuable insights into ancient cultures and knowledge.

Chichén Itzá is located in the eastern portion of Yucatán state in Mexico. 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 Chichen, making it attractive for settlement. Of these cenotes,

A study of human remains taken from the Cenote Sagrado found that they had wounds consistent with human sacrifice. Several archeologists in the late 1980s suggested that unlike previous Maya polities of the Early Classic, Chichén Itzá may not have been governed by an individual ruler or

The Ancestral Puebloans thrived in what is now the Four Corners region in the United States. It is commonly suggested that the culture of the Ancestral Puebloans emerged during the Early Basketmaker II Era during the 12th century BCE. The Ancestral Puebloans were a complex Oasisamerican society that constructed kivas , multi-story houses, and apartment blocks made from stone and adobe, such as
6432-483: The Olmec resulted in a power vacuum in Mexico. Emerging from that vacuum was Teotihuacan, first settled in 300 BCE. By 150 CE, Teotihuacan had risen to become the first true metropolis of what is now called North America. Teotihuacan established a new economic and political order never before seen in Mexico. Its influence stretched across Mexico into Central America, founding new dynasties in the Maya cities of Tikal , Copan , and Kaminaljuyú . Teotihuacan's influence over

These civilizations (except for the politically fragmented Maya) extended their reach across Mesoamerica—and beyond—like no others. They consolidated power and distributed influence in matters of trade, art, politics, technology, and theology. Other regional power players made economic and political alliances with these civilizations over 4,000 years. Many made war with them, but almost all peoples found themselves within one of their spheres of influence. Regional communications in ancient Mesoamerica have been

Thompson is most famous for dredging the Cenote Sagrado (Sacred Cenote) from 1904 to 1910, where he recovered artifacts of gold, copper and carved jade, as well as the first-ever examples of what were believed to be pre-Columbian Maya cloth and wooden weapons. Thompson shipped the bulk of the artifacts to the Peabody Museum at Harvard University . In 1913, the Carnegie Institution accepted
6834-662: The Paleo-Indian period, bands are thought to have subsisted primarily through hunting now-extinct giant land animals such as mastodon and ancient bison . Paleo-Indian groups carried a variety of tools, including distinctive projectile points and knives, as well as less distinctive butchering and hide-scraping implements. The vastness of the North American continent, and the variety of its climates, ecology , vegetation , fauna , and landforms, led ancient peoples to coalesce into many distinct linguistic and cultural groups.

Their achievements paved the way for the Maya civilization and the civilizations in central Mexico. The decline of
9782-462: The collapse of both cities. According to some colonial Mayan sources (e.g., the Book of Chilam Balam of Chumayel), Hunac Ceel , ruler of Mayapan , conquered Chichén Itzá 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,
9916-408: The collapse of limestone, and located across the peninsula. Some of these cenotes are at risk from the construction of the new tourist Maya Train . Cenotes are common geological forms in low-altitude regions, particularly on islands (such as Cefalonia, Greece), coastlines, and platforms with young post- Paleozoic limestone with little soil development. The term cenote , originally applying only to
10050-541: The de Soto expedition wandered the American Southeast for four years, becoming more bedraggled, losing more men and equipment, and eventually arriving in Mexico as a fraction of its original size. The local people fared much worse though, as the fatalities of diseases introduced by the expedition devastated the populations and produced much social disruption. By the time Europeans returned a hundred years later, nearly all of
10184-656: The decline of the Toltec civilization came political fragmentation in the Valley of Mexico . Into this new political game of contenders to the Toltec throne stepped outsiders: the Mexica . They were also a desert people, one of seven groups who formerly called themselves "Azteca", in memory of Aztlán , but they changed their name after years of migrating. Since they were not from the Valley of Mexico , they were initially seen as crude and unrefined in
10318-451: The development of archaeology in the 19th century, historians of the pre-Columbian period mainly interpreted the records of the European conquerors and the accounts of early European travelers and antiquaries. It was not until the nineteenth century that the work of people such as John Lloyd Stephens , Eduard Seler , and Alfred Maudslay , and institutions such as the Peabody Museum of Archaeology and Ethnology of Harvard University , led to
10452-404: The direction of Rafael (Rach) Cobos. Chichen Itza was one of the largest Maya cities, with the relatively densely clustered architecture of the site core covering an area of at least 5 square kilometers (1.9 sq mi). Smaller scale residential architecture extends for an unknown distance beyond this. The city was built upon broken terrain, which was artificially levelled in order to build
10586-542: 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. 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. Chichén Itzá rose to regional prominence toward
10720-591: The empire from 700 BCE to 700 CE. The Zapotecs resisted the expansion of the Aztecs until they were subjugated in 1502 under Aztec emperor Ahuitzotl . After the Spanish conquest of the Aztec Empire , the Zapotecs resisted Spanish rule until King Cosijopii I surrendered in 1563. Like the Zapotecs, the Mixtecs thrived in the Oaxaca Valley. The Mixtecs consisted of separate independent kingdoms and city-states, rather than
10854-574: 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
10988-575: The end of the period when they were replaced by bows and arrows . The Mississippian culture was spread across the Southeast and Midwest of what is today the United States, from the Atlantic coast to the edge of the plains, from the Gulf of Mexico to the Upper Midwest, although most intensively in the area along the Mississippi River and Ohio River . One of the distinguishing features of this culture
11122-457: The establishment of cities, such as El Tajín as important commercial trading centers. The Totonacs would later assist in the Spanish conquest of the Aztec Empire as an opportunity to liberate themselves from Aztec military imperialism. The Toltec civilization was established in the 8th century CE. The Toltec Empire expanded its political borders to as far south as the Yucatán peninsula , including
11256-747: The features in Yucatán, has since been applied by researchers to similar karst features in other places such as in Cuba , Australia , Europe , and the United States . Cenotes are surface connections to subterranean water bodies. While the best-known cenotes are large open-water pools measuring tens of meters in diameter, such as those at Chichen Itza in Mexico , the greatest number of cenotes are smaller sheltered sites and do not necessarily have any surface exposed water. Some cenotes are only found through small <1 m (3 ft) diameter holes created by tree roots, with human access through enlarged holes, such as
11390-403: The first Cazonci, Tariacuri, united these communities and built them into one of the most advanced civilizations in Mesoamerica. Their capital at Tzintzuntzan was just one of the many cities—there were ninety more under its control. The Tarascan Empire was among the largest in Central America, so it is no surprise that they routinely came into conflict with the neighboring Aztec Empire . Out of all
11524-604: The first long-form description of Chichen Itza in his book, Biologia Centrali-Americana . In 1894, the United States Consul to Yucatán, Edward Herbert Thompson , purchased the Hacienda Chichén , which included the ruins of Chichen Itza. For 30 years, Thompson explored the ancient city. His discoveries included the earliest dated carving upon a lintel in the Temple of the Initial Series and the excavation of several graves in
11658-400: The former Toltec Empire , they were also quite independent in culture from their neighbors. The Aztecs, Tlaxcaltec , Olmec, Mixtec, Maya, and others were very similar to each other, however. This is because they were all directly preceded by the Toltecs, and they therefore shared almost identical cultures. The Tarascans, however, possessed a unique religion, as well as other things. Tlaxcala
11792-411: The halocline is a function of several factors: climate and specifically how much meteoric water recharges the aquifer, hydraulic conductivity of the host rock, distribution and connectivity of existing cave systems, and how effective these are at draining water to the coast, and the distance from the coast. In general, the halocline is deeper further from the coast, and in the Yucatán Peninsula this depth
11926-592: The impact was minimal or did not exist, pointing to numerous differences between the two systems and the ample precedents for the constitution in European political thought. The Calusa were a complex paramountcy/kingdom that resided in southern Florida . Instead of agriculture, the Calusa economy relied on abundant fishing. According to Spanish sources, the "king's house" at Mound Key was large enough to house 2,000 people. The Calusa ultimately collapsed into extinction at around 1750 after succumbing to diseases introduced by
12060-687: The influence that astronomical activities had upon Mesoamerican people before the arrival of Europeans. Many of the later Mesoamerican civilizations carefully built their cities and ceremonial centers according to specific astronomical events. The biggest Mesoamerican cities, such as Teotihuacan , Tenochtitlan , and Cholula , were among the largest in the world. These cities grew as centers of commerce, ideas, ceremonies, and theology, and they radiated influence outwards onto neighboring cultures in central Mexico. While many city-states, kingdoms, and empires competed with one another for power and prestige, Mesoamerica can be said to have had five major civilizations:
12194-429: The initial colonization of the region. The Na-Dené , Inuit , and Indigenous Alaskan populations exhibit haplogroup Q-M242 (Y-DNA) mutations, however, and are distinct from other Indigenous peoples with various mtDNA mutations. This suggests that the earliest migrants into the northern extremes of North America and Greenland derived from later populations. Asian nomadic Paleo-Indians are thought to have entered
12328-540: The inner walls, including a center figure that has carving under his chin that resembles facial hair. At the south end is another, much bigger temple, but in ruins. Built into the east wall are the Temples of the Jaguar . The Upper Temple of the Jaguar overlooks the ball court and has an entrance guarded by two, large columns carved in the familiar feathered serpent motif. Inside there is a large mural, much destroyed, which depicts
12462-472: The late Aztec period (1350–1519). Their capital, Tenochtitlan , is the site of modern-day Mexico City . At its peak, it was one of the largest cities in the world with population estimates of 200,000–300,000. The market established there was the largest ever seen by the conquistadores on arrival. Initially, the lands that would someday comprise the lands of the powerful Tarascan Empire were inhabited by several independent communities. Around 1300, however,
12596-607: The late twentieth century, archeologists have studied, analyzed, and dated these sites, realizing that the earliest complexes were built by hunter-gatherer societies, whose people occupied the sites on a seasonal basis. Watson Brake , a large complex of eleven platform mounds, was constructed beginning in 3400 BCE and added to over 500 years. This has changed earlier assumptions that complex construction arose only after societies had adopted agriculture, and become sedentary, with stratified hierarchy and usually ceramics. These ancient people had organized to build complex mound projects under
12730-545: The major architectural groups, with the greatest effort being expended in the levelling of the areas for the Castillo pyramid, and the Las Monjas, Osario and Main Southwest groups. The site contains many fine stone buildings in various states of preservation, and many have been restored. The buildings were connected by a dense network of paved causeways, called sacbeob . Archeologists have identified over 80 sacbeob criss-crossing
12864-399: The major centers of the southern Maya lowlands. As Chichén Itzá 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
12998-455: The majority of the Y-chromosome is unique and does not recombine during meiosis . This has the effect that the historical pattern of mutations can easily be studied. The pattern indicates Indigenous peoples of the Americas experienced two very distinctive genetic episodes: first with the initial peopling of the Americas and second with European colonization of the Americas . The former
13132-511: The measured rim of the Chicxulub crater . This crater structure, identified from the alignment of cenotes, but also subsequently mapped using geophysical methods (including gravity mapping ) and also drilled into with core recovery, has been dated to the boundary between the Cretaceous and Paleogene geologic periods, 66 million years ago. This meteorite impact at the Cretaceous–Paleogene boundary
13266-591: The modern water table. However, very few of these cenotes appear to be connected with horizontally extensive underground river systems, with water flow through them being more likely dominated by aquifer matrix and fracture flows. In contrast, the cenotes along the Caribbean coast of the Yucatán Peninsula (within the state of Quintana Roo ) often provide access to extensive underwater cave systems, such as Sistema Ox Bel Ha , Sistema Sac Actun / Sistema Nohoch Nah Chich and Sistema Dos Ojos . The Yucatán Peninsula contains
13400-577: The monuments of the Temple of Kukulcán (El Castillo), Temple of Warriors and the Great Ball Court; The Osario Group, which includes the pyramid of the same name as well as the Temple of Xtoloc; and the Central Group, which includes the Caracol, Las Monjas, and Akab Dzib. South of Las Monjas, in an area known as Chichén Viejo (Old Chichén) and only open to archeologists, are several other complexes, such as
13534-407: The most secluded and darker cenotes, the fauna has evolved to resemble those of many cave-dwelling species. For example, many animals don't have pigmentation and are often blind, so they are equipped with long feelers to find food and make their way around in the dark. Although cenotes are found widely throughout much of the Yucatán Peninsula, a higher-density circular alignment of cenotes overlies
13668-430: The mouth of the well of the Itza." 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 Itza is "enchanter (or enchantment) of the water," from its (itz), "sorcerer", and ha , "water". The name is spelled Chichén Itzá in Spanish, and
13802-443: The north-west of the Castillo is the most impressive. It is the largest and best preserved ball court in ancient Mesoamerica. It measures 168 by 70 meters (551 by 230 ft). The parallel platforms flanking the main playing area are each 95 meters (312 ft) long. The walls of these platforms stand 8 meters (26 ft) high; set high up in the center of each of these walls are rings carved with intertwined feathered serpents. At
13936-490: The only perennial source of potable water and have long been the principal source of water in much of the region. Major Maya settlements required access to adequate water supplies, and therefore cities, including the famous Chichen Itza , were built around these natural wells. Many cenotes like the Sacred Cenote in Chichen Itza played an important role in Maya rites. The Maya believed that cenotes were portals to Xibalba or
14070-510: The only true writing system native to the Americas using pictographs and syllabic elements in the form of texts and codices inscribed on stone, pottery, wood, or perishable books made from bark paper. The Huastecs were a Maya ethnic group that migrated northwards to the Gulf Coast of Mexico. The Huastecs are considered to be distinct from the Maya civilization, as they separated from the main Maya branch at around 2000 BCE and did not possess
14204-646: The people abandoned their settlements, likely due to drought. The Mogollon resided in the present-day states of Arizona , New Mexico, and Texas as well as Sonora and Chihuahua . Like most other cultures in Oasisamerica, the Mogollon constructed sophisticated kivas and cliff dwellings. In the village of Paquimé , the Mogollon are revealed to have housed pens for scarlet macaws , which were introduced from Mesoamerica through trade. The Sinagua were hunter-gatherers and agriculturalists who lived in central Arizona. Like
14338-416: The prehistoric Americas . The culture reached its peak in about 1200–1400 CE, and in most places, it seems to have been in decline before the arrival of Europeans. Many Mississippian peoples were encountered by the expedition of Hernando de Soto in the 1540s, mostly with disastrous results for both sides. Unlike the Spanish expeditions in Mesoamerica, which conquered vast empires with relatively few men,
14472-408: The presence of these non-Maya styles more as the result of cultural diffusion . Chichén Itzá 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
14606-437: The processes by which the cenotes formed and the inherent hydrogeochemical relationship with the underlying flooded cave networks, which were only discovered in the 1980s and later with the initiation of cave diving exploration. Flora and fauna are generally scarcer than in the open ocean; however, marine animals do thrive in caves. In caverns, one can spot mojarras , mollies , guppies , catfish , small eels and frogs . In
14740-556: The proposal of archeologist Sylvanus G. Morley and committed to conduct long-term archeological research at Chichen Itza. The Mexican Revolution and the following government instability, as well as World War I, delayed the project by a decade. In 1923, the Mexican government awarded the Carnegie Institution a ten-year permit (later extended by another ten years) to allow U.S. archeologists to conduct extensive excavation and restoration of Chichen Itza. Carnegie researchers excavated and restored
14874-477: The public. Around the Spring and Autumn equinoxes , in the late afternoon, the northwest corner of the pyramid casts a series of triangular shadows against the western balustrade on the north side that evokes the appearance of a serpent wriggling down the staircase, which some scholars have suggested is a representation of the feathered-serpent deity, Kukulcán. It is a widespread belief that this light-and-shadow effect
15008-613: The reconsideration and criticism of the early European sources. Now, the scholarly study of pre-Columbian cultures is most often based on scientific and multidisciplinary methodologies. The haplogroup most commonly associated with Indigenous Amerindian genetics is Y-chromosome haplogroup Q1a3a . Researchers have found genetic evidence that the Q1a3a haplogroup has been in South America since at least 18,000 BCE. Y-chromosome DNA , like mtDNA , differs from other nuclear chromosomes in that
15142-581: The region was a factor in the conquistadors' decision to locate a capital there. According to post-Conquest sources, both Spanish and Maya, the Cenote Sagrado remained a place of pilgrimage. In 1526, Spanish Conquistador Francisco de Montejo (a veteran of the Grijalva and Cortés expeditions) successfully petitioned the King of Spain for a charter to conquer Yucatán. His first campaign in 1527, which covered much of
15276-511: The rest of North and South America. Exactly when the first people migrated into the Americas is the subject of much debate. One of the earliest identifiable cultures was the Clovis culture , with sites dating from some 13,000 years ago. However, older sites dating back to 20,000 years ago have been claimed. Some genetic studies estimate the colonization of the Americas dates from between 40,000 and 13,000 years ago. The chronology of migration models
15410-466: The ruins of the ancient city. Months passed, but no reinforcements arrived. Montejo the Younger attempted an all-out assault against the Maya and lost 150 of his remaining troops. He was forced to abandon Chichén Itzá in 1534 under cover of darkness. By 1535, all Spanish had been driven from the Yucatán Peninsula. Montejo eventually returned to Yucatán and, by recruiting Maya from Campeche and Champoton, built
15544-457: The site, and extending in all directions from the city. Many of these stone buildings were originally painted in red, green, blue and purple colors. Pigments were chosen according to what was most easily available in the area. The site must be imagined as a colorful one, not like it is today. Just like Gothic cathedrals in Europe, colors provided a greater sense of completeness and contributed greatly to
15678-540: The site, with the most important being the Las Monjas group. Dominating the North Platform of Chichen Itza is the Temple of Kukulcán (a Maya feathered serpent deity similar to the Aztec Quetzalcoatl ). The temple was identified by the first Spaniards to see it, as El Castillo ("the castle"), and it regularly is referred to as such. This step pyramid stands about 30 meters (98 ft) high and consists of
15812-485: The site. The ruins of Chichén Itzá 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). The land under the monuments had been privately owned until 29 March 2010, when it was purchased by the state of Yucatán. Chichén Itzá is one of the most visited archeological sites in Mexico with over 2.6 million tourists in 2017. The Maya name "Chichen Itza" means "At
15946-545: The southern tip of South America by this time. In that case, the Inuit would have arrived separately and at a much later date, probably no more than 2,000 years ago, moving across the ice from Siberia into Alaska. The North American climate was unstable as the ice age receded during the Lithic stage . It finally stabilized about 10,000 years ago; climatic conditions were then very similar to today's. Within this time frame, roughly about
16080-609: The style but differ from the architecture of the Puuc heartland in their block masonry walls, as opposed to the fine veneers of the Puuc region proper. At least one structure in the Las Monjas Group features an ornate façade and masked doorway that are typical examples of Chenes-style architecture, a style centered upon a region in the north of Campeche state, lying between the Puuc and Río Bec regions. Those structures with sculpted hieroglyphic script are concentrated in certain areas of
16214-545: The subject of considerable research. There is evidence of trade routes starting as far north as the Mexico Central Plateau , and going down to the Pacific coast. These trade routes and cultural contacts then went on as far as Central America . These networks operated with various interruptions from pre-Olmec times and up to the Late Classical Period (600–900 CE). The earliest known civilization in Mesoamerica
16348-454: The subsequent structural collapse. Rock that falls into the water below is slowly removed by further dissolution, creating space for more collapse blocks. Likely, the rate of collapse increases during periods when the water table is below the ceiling of the void since the rock ceiling is no longer buoyantly supported by the water in the void. Cenotes may be fully collapsed, creating an open water pool, or partially collapsed with some portion of
16482-465: The symbolic impact of the buildings. The architecture encompasses a number of styles, including the Puuc and Chenes styles of the northern Yucatán Peninsula. The buildings of Chichen Itza are grouped in a series of architectonic sets, and each set was at one time separated from the other by a series of low walls. The three best known of these complexes are the Great North Platform, which includes
16616-403: The top, they found another temple buried below the current one. Inside the temple chamber was a Chac Mool statue and a throne in the shape of Jaguar, painted red and with spots made of inlaid jade. The Mexican government excavated a tunnel from the base of the north staircase, up the earlier pyramid's stairway to the hidden temple, and opened it to tourists. In 2006, INAH closed the throne room to
16750-498: The visits to the Caribbean by Christopher Columbus. Mesoamerican is the adjective generally used to refer to that group of pre-Columbian cultures. This refers to an environmental area occupied by an assortment of ancient cultures that shared religious beliefs, art, architecture, and technology in the Americas for more than three thousand years. Between 2000 and 300 BCE, complex cultures began to form in Mesoamerica. Some matured into advanced pre-Columbian Mesoamerican civilizations such as
16884-496: The ways of the Nahua civilization. Through political maneuvers and ferocious martial skills, they managed to rule Mexico as the head of the 'Triple Alliance' which included two other Aztec cities, Tetxcoco and Tlacopan . Latecomers to Mexico's central plateau , the Mexica thought of themselves, nevertheless, as heirs of the civilizations that had preceded them. For them, arts, sculpture, architecture, engraving, feather-mosaic work, and
17018-420: The wheel, but it was used solely as a toy. In addition, they used native copper , silver , and gold for metalworking. Archaic inscriptions on rocks and rock walls all over northern Mexico (especially in the state of Nuevo León ) demonstrate an early propensity for counting. Their number system was base 20 and included zero . These early count markings were associated with astronomical events and underscore
17152-654: The word tracing its origins to a Navajo word meaning "ancestor enemies". The Hohokam thrived in the Sonoran desert in what is now the U.S. state of Arizona and the Mexican state of Sonora . The Hohokam were responsible for the construction of a series of irrigation canals that led to the successful establishment of Phoenix, Arizona via the Salt River Project . The Hohokam also established complex settlements such as Snaketown , which served as an important commercial trading center. After 1375 CE, Hohokam society collapsed and
17286-487: Was a Nahua republic and confederation in central Mexico. The Tlaxcalans fiercely resisted Aztec expansion during the Flower Wars ever since the Aztecs expelled them from Lake Texcoco . The Tlaxcalans would later ally with the Spanish conquistadors under Hernán Cortés as an opportunity to liberate them from the Aztecs and managed to successfully conquer the Aztecs with the help of the conquistadors. The Spaniards would reward
17420-416: Was a time of intense flourishing of Maya civilized accomplishments. While the many Maya city-states never achieved political unity on the order of the central Mexican civilizations, they exerted tremendous intellectual influence upon Mexico and Central America. The Maya built some of the most elaborate cities on the continent and made innovations in mathematics, astronomy, and calendrics. The Maya also developed
17554-501: Was achieved on purpose to record the equinoxes, but the idea is highly unlikely: it has been shown that the phenomenon can be observed, without major changes, during several weeks around the equinoxes, making it impossible to determine any date by observing this effect alone. Archeologists have identified in Chichen Itza thirteen ballcourts for playing the Mesoamerican ballgame , but the Great Ball Court about 150 meters (490 ft) to
17688-573: Was adopted in more temperate and sheltered regions, permitting a dramatic rise in population. After the migration or migrations, it was several thousand years before the first complex societies arose, the earliest emerging about seven to eight thousand years ago. As early as 5500 BCE, people in the Lower Mississippi Valley at Monte Sano and other sites in present-day Louisiana , Mississippi , and Florida were building complex earthwork mounds , probably for religious purposes. Beginning in
17822-638: Was in the United States at the time, never returned to Yucatán. He wrote about his research and investigations of the Maya culture in a book People of the Serpent published in 1932. He died in New Jersey in 1935. In 1944 the Mexican Supreme Court ruled that Thompson had broken no laws and returned Chichen Itza to his heirs. The Thompsons sold the hacienda to tourism pioneer Fernando Barbachano Peon. There have been two later expeditions to recover artifacts from
17956-538: Was the construction of complexes of large earthen mounds and grand plazas, continuing the mound-building traditions of earlier cultures. They grew maize and other crops intensively, participated in an extensive trade network, and had a complex stratified society. The Mississippians first appeared around 1000 CE, following and developing out of the less agriculturally intensive and less centralized Woodland period. The largest urban site of these people, Cahokia —located near modern East St. Louis, Illinois —may have reached
