Nahuatl in the context of Barbacoa

The Indigenous peoples of the Americas are the peoples who are native to the Americas or the Western Hemisphere. Their ancestors are among the pre-Columbian population of South or North America, including Central America and the Caribbean. Indigenous peoples live throughout the Americas. While often minorities in their countries, Indigenous peoples are the majority in Greenland and close to a majority in Bolivia and Guatemala.

There are at least 1,000 different Indigenous languages of the Americas. Some languages, including Quechua, Arawak, Aymara, Guaraní, Nahuatl, and some Mayan languages, have millions of speakers and are recognized as official by governments in Bolivia, Peru, Paraguay, and Greenland.

New Spain, officially the Viceroyalty of New Spain (Spanish: Virreinato de Nueva España [birejˈnato ðe ˈnweβa esˈpaɲa] ; Nahuatl: Yankwik Kaxtillan Birreiyotl), originally the Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain. It was one of several domains established during the Spanish conquest of the Americas, and had its capital in Mexico City. Its jurisdiction comprised a large area of the southern and western portions of North America, mainly what became Mexico and the Southwestern United States, but also California, Florida and Louisiana; Central America (as part of Mexico); the Caribbean like Hispaniola and Martinique, and northern parts of South America, even Colombia; several Pacific archipelagos, including the Philippines and Guam. Additional Asian colonies included "Spanish Formosa", on the island of Taiwan.

After the 1521 Spanish conquest of the Aztec Empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of Tenochtitlan, the capital of the Aztec Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the political and economic importance of the conquest, the crown asserted direct control over the densely populated realm. The crown established New Spain as a viceroyalty in 1535, appointing as viceroy Antonio de Mendoza, an aristocrat loyal to the monarch rather than the conqueror Cortés. New Spain was the first of the viceroyalties that Spain created, the second being Peru in 1542, following the Spanish conquest of the Inca Empire. Both New Spain and Peru had dense indigenous populations at conquest as a source of labor and material wealth in the form of vast silver deposits, discovered and exploited beginning in the mid-1600s.

The Laurentian Library (Biblioteca Medicea Laurenziana or BML) is a historic library in Florence, Italy, containing more than 11,000 manuscripts and 4,500 early printed books. Built in a cloister of the Medicean Basilica di San Lorenzo di Firenze under the patronage of the Medici pope Clement VII, the library was built to emphasize that the Medici were no longer just merchants but members of intelligent and ecclesiastical society. It contains the manuscripts and books belonging to the private library of the Medici family. The library building is renowned for its architecture that was designed by Michelangelo and is an example of Mannerism.

All of the book-bound manuscripts in the library are identified in its Codex Laurentianus. The library conserves the Nahuatl Florentine Codex, the Rabula Gospels, the Codex Amiatinus, the Squarcialupi Codex, and the fragmentary Erinna papyrus that contains part of her Distaff.

Benjamin Atwood Lee Whorf (/hwɔːrf/; April 24, 1897 – July 26, 1941) was an American linguist and fire prevention engineer best known for proposing the Sapir–Whorf hypothesis. He believed that the structures of different languages shape how their speakers perceive and conceptualize the world. Whorf saw this idea, named after him and his mentor Edward Sapir, as having implications similar to those of Einstein's principle of physical relativity. However, the concept originated from 19th-century philosophy and thinkers like Wilhelm von Humboldt and Wilhelm Wundt.

Whorf initially pursued chemical engineering but developed an interest in linguistics, particularly Biblical Hebrew and indigenous Mesoamerican languages. His groundbreaking work on the Nahuatl language earned him recognition, and he received a grant to study it further in Mexico. He presented influential papers on Nahuatl upon his return. Whorf later studied linguistics with Edward Sapir at Yale University while working as a fire prevention engineer.

The Aztecs (/ˈæztɛks/ AZ-teks) were a Mesoamerican civilization that flourished in central Mexico from 1300 to 1521. The Aztec people included different ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language. Aztec culture was organized into city-states (altepetl), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan (the capital city of the Mexica or Tenochca), Tetzcoco, and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahua polities or peoples of central Mexico in the prehispanic era, as well as the Spanish colonial era (1521–1821).

Most ethnic groups of central Mexico in the post-classic period shared essential cultural traits of Mesoamerica. The culture of central Mexico includes maize cultivation, the social division between nobility (pipiltin) and commoners (macehualtin), a pantheon, and the calendric system. Particular to the Mexica of Tenochtitlan was the patron god Huitzilopochtli, twin pyramids, and the ceramic styles known as Aztec I to IV. The Mexica were late-comers to the Valley of Mexico, and founded the city-state of Tenochtitlan on unpromising islets in Lake Texcoco, later becoming the dominant power of the Aztec Triple Alliance or Aztec Empire which conquered other city-states throughout Mesoamerica. It originated in 1427 as an alliance between the city-states Tenochtitlan, Texcoco, and Tlacopan to defeat the Tepanec state of Azcapotzalco, which had previously dominated the Basin of Mexico. Soon Texcoco and Tlacopan were relegated to junior partnership in the alliance, with Tenochtitlan the dominant power. The empire extended its reach by a combination of trade and military conquest. It was never a true territorial empire controlling territory by large military garrisons in conquered provinces but rather dominated its client city-states primarily by installing friendly rulers in conquered territories, constructing marriage alliances between the ruling dynasties, and extending an imperial ideology to its client city-states. Client city-states paid taxes, not tribute to the Aztec emperor, the Huey Tlatoani, in an economic strategy limiting communication and trade between outlying polities, making them dependent on the imperial center for the acquisition of luxury goods. The political clout of the empire reached far south into Mesoamerica conquering polities as far south as Chiapas and Guatemala and spanning Mesoamerica from the Pacific to the Atlantic oceans.

The Nahuan or Aztecan languages are those languages of the Uto-Aztecan language family that have undergone a sound change, known as Whorf's law, that changed an original *t to /tɬ/ before *a. Subsequently, some Nahuan languages have changed this /tɬ/ to /l/ or back to /t/, but it can still be seen that the language went through a /tɬ/ stage. The most spoken Nahuatl variant is Huasteca Nahuatl. As a whole, Nahuatl is spoken by about 1.7 million Nahua peoples.

Some authorities, such as the Mexican government, Ethnologue, and Glottolog, consider the varieties of modern Nahuatl to be distinct languages, because they are often mutually unintelligible, their grammars differ and their speakers have distinct ethnic identities. As of 2008, the Mexican government recognizes thirty varieties that are spoken in Mexico as languages (see the list below).

In a protracted conflict during the Spanish colonization of the Americas, Spanish colonisers gradually incorporated the territory that became the modern country of Guatemala into the colonial Viceroyalty of New Spain. Before the conquest, this territory contained a number of competing Mesoamerican kingdoms, the majority of which were Maya. Many conquistadors viewed the Maya as "infidels" who needed to be forcefully converted and pacified, disregarding the achievements of their civilization. The first contact between the Maya and European explorers came in the early 16th century when a Spanish ship sailing from Panama to Santo Domingo (Hispaniola) was wrecked on the east coast of the Yucatán Peninsula in 1511. Several Spanish expeditions followed in 1517 and 1519, making landfall on various parts of the Yucatán coast. The Spanish conquest of the Maya was a prolonged affair; the Maya kingdoms resisted integration into the Spanish Empire with such tenacity that their defeat took almost two centuries.

Pedro de Alvarado arrived in Guatemala from the newly conquered Mexico in early 1524, commanding a mixed force of Spanish conquistadors and native allies, mostly from Tlaxcala and Cholula. Geographic features across Guatemala now bear Nahuatl placenames owing to the influence of these Mexican allies, who translated for the Spanish. The Kaqchikel Maya initially allied themselves with the Spanish, but soon rebelled against excessive demands for tribute and did not finally surrender until 1530. In the meantime the other major highland Maya kingdoms had each been defeated in turn by the Spanish and allied warriors from Mexico and already subjugated Maya kingdoms in Guatemala. The Itza Maya and other lowland groups in the Petén Basin were first contacted by Hernán Cortés in 1525, but remained independent and hostile to the encroaching Spanish until 1697, when a concerted Spanish assault led by Martín de Ursúa y Arizmendi finally defeated the last independent Maya kingdom.

Naucalpan, officially Naucalpan de Juárez, is one of 125 Municipalities of Mexico State, and is located just northwest of Mexico City. The municipal seat is the city of Naucalpan de Juárez, which extends into the neighboring municipality of Huixquilucan.

The name Naucalpan comes from Nahuatl and means "place of the four neighborhoods" or "four houses." Juárez was added to the official name in 1874 in honor of Benito Juárez. The history of the area begins with the Tlatilica who settled on the edges of the Hondo River between 1700 and 600 B.C.E., but it was the Mexica who gave it its current name when they dominated it from the 15th century until the Spanish conquest of the Mexica Empire. Naucalpan claims to be the area where Hernán Cortés rested on the "Noche Triste" as they fled Tenochtitlan in 1520, but this is disputed. It is the home of the Virgin of Los Remedios, a small image of the Virgin Mary which is strongly associated with the Conquest and is said to have been left here.

Tlahtoāni (Classical Nahuatl: tlahtoāni pronounced [t͡ɬaʔtoˈaːniˀ] , "ruler, sovereign"; plural tlahtohqueh [t͡ɬaʔˈtoʔkeʔ]) is a historical title used by the dynastic rulers of āltepēmeh (singular āltepētl, often translated into English as "city-state"), autonomous political entities formed by many pre-Columbian Nahuatl-speaking peoples in the Valley of Mexico during the Postclassic Period. The title of huēyi tlahtoāni [es] ([ˈweːjiˀ t͡ɬaʔtoˈaːniˀ], "great ruler, emperor") was used by the rulers of the Aztec Empire, an alliance between the āltepēmeh of Tenochtitlan, Tetzcoco, and Tlacopan.

Each āltepētl had its own tlahtoāni who would concurrently function as its ruler, high priest and commander-in-chief. The tlahtoāni wielded ultimate authority over all land within the āltepētl, overseeing tribute collection, market activities, temple affairs, and the resolution of judicial disputes. Typically a dynastic ruler hailing from the royal lineage, the tlahtoāni served for life. However, in certain instances, a council of nobles, elders, and priests could elect a tlahtoāni from a pool of four candidates.

Classical Nahuatl, also known simply as Aztec or Codical Nahuatl (if it refers to the variants employed in the Mesoamerican Codices through the medium of Aztec Hieroglyphs) and Colonial Nahuatl (if written in Post-conquest documents in the Latin alphabet), is a set of variants of Nahuatl spoken in the Valley of Mexico and central Mexico as a lingua franca at the time of the 16th-century Spanish conquest of the Aztec Empire. During the subsequent centuries, it was largely displaced by Spanish and evolved into some of the modern Nahuan languages in use (other modern dialects descend more directly from other 16th-century variants). Although classified as an extinct language, Classical Nahuatl has survived through a multitude of written sources transcribed by Nahua peoples and Spaniards in the Latin script.

The Nahuas (/ˈnɑːwɑːz/ NAH-wahz) are a Uto-Nahuan ethnic group and one of the Indigenous people of Mexico, with Nahua minorities also in El Salvador, Guatemala, Honduras, Nicaragua, and Costa Rica. They comprise the largest Indigenous group in Mexico, as well as the largest population out of any North American Indigenous people group who are native speakers of their respective Indigenous language. Amongst the Nahua, this is Nahuatl. When ranked amongst all Indigenous languages across the Americas, Nahuas list third after speakers of Guaraní and Quechua.

The Mexica (Aztecs) are of Nahua ethnicity, as are their historical enemies and allies of the Spaniards: the Tlaxcallans (Tlaxcaltecs). The Toltecs which predated both groups are often thought to have been Nahua as well. However, in the pre-Columbian period Nahuas were subdivided into many groups that did not necessarily share a common identity.

The altepetl (Classical Nahuatl: āltepētl [aːɬ.ˈte.peːt͡ɬ] , plural altepeme or altepemeh [aːɬ.ˈte.ˈpeːme(h)]) was the local, ethnically-based political entity, usually translated into English as "city-state", of pre-Columbian Nahuatl-speaking societies in the Americas. The altepetl was composed of smaller units known as calpolli and was typically led by a single dynastic ruler known as a tlatoani, although examples of shared rule between up to five rulers are known. Each altepetl had its own jurisdiction, origin story, and served as the center of Indigenous identity. Residents referred to themselves by the name of their altepetl rather than, for instance, as "Mexicas". "Altepetl" was a polyvalent term rooting the social and political order in the creative powers of a sacred mountain that contained the ancestors, seeds and life-giving forces of the community. The word is a combination of the Nahuatl words ātl (meaning "water") and tepētl (meaning "mountain"). A characteristic Nahua mode was to imagine the totality of the people of a region or of the world as a collection of altepetl units and to speak of them on those terms. The concept is comparable to Maya cah and Mixtec ñuu. Altepeme formed a vast complex network which predated and outlasted larger empires, such as the Aztec and Tarascan state.

Established altepeme were characterized by a central temple dedicated to a patron god particular to the identity of the altepetl and a central market. Altepeme were typically multiethnic and communal cohesion was often maintained through territorial exclusiveness.

Azcapotzalco was a pre-Columbian Nahua altepetl (state), capital of the Tepanec empire, in the Valley of Mexico, on the western shore of Lake Texcoco.

The name Azcapotzalco means "at the anthill" in Nahuatl. Its inhabitants were called Azcapotzalca.

Aztec codices (Nahuatl languages: Mēxihcatl āmoxtli, pronounced [meːˈʃiʔkatɬ aːˈmoʃtɬi]; sg.: codex) are Mesoamerican manuscripts made by the pre-Columbian Aztec, and their Nahuatl-speaking descendants during the colonial period in Mexico. Most of their content is pictorial in nature and they come from the multiple Indigenous groups from before and after Spanish contact. Differences in styles indicate regional and temporal differences. The types of information in manuscripts fall into several broad categories: calendar or time, history, genealogy, cartography, economics/tributes, census and cadastral, and property plans. Codex Mendoza and the Florentine Codex are among the important and popular colonial-era codices. The Florentine Codex, for example is known for providing a Mexica narrative of the Spanish Conquest from the viewpoint of the Indigenous people, instead of Europeans.

A tortilla (/tɔːrˈtiːə/, Spanish: [toɾˈtiʝa]) is a thin, circular unleavened flatbread from Mesoamerica originally made from masa, and now also from wheat flour.

The Aztecs and other Nahuatl speakers called tortillas tlaxcalli ([t͡ɬaʃˈkalli]). First made by the indigenous peoples of Mesoamerica before colonization, tortillas are a cornerstone of Mesoamerican cuisine. Corn tortillas in Mesoamerica are known from as early as 500 BCE. Flour tortillas were invented once the Spanish introduced wheat to Mexico in the 16th century.
