Originally conceived in 1979 by the General Foods company as a symbol of the firm's "aggressive consumer products packaging and marketing", it is known for its distinctive glass and white aluminum exterior. Upon its opening in 1983, General Foods relocated 2,000 headquarters staff from nearby White Plains . However, in 1985, General Foods
304-810: A conventional breeding program to provide optimized strains. The program began in the 1980s. Hybrid seeds are distributed in Africa by its Drought Tolerant Maize for Africa project. Tropical landraces remain an important and underused source of resistance alleles – both those for disease and for herbivores . Such alleles can then be introgressed into productive varieties. Rare alleles for this purpose were discovered by Dao and Sood, both in 2014. In 2018, Zerka Rashid of CIMMYT used its association mapping panel, developed for tropical drought tolerance traits. to find new genomic regions providing sorghum downy mildew resistance , and to further characterize known differentially methylated regions . Genetically modified maize
456-403: A corn head (with points and snap rolls instead of a reel) does not cut the stalk; it simply pulls the stalk down. The stalk continues downward and is crumpled into a mangled pile on the ground, where it usually is left to become organic matter for the soil . The ear of maize is too large to pass between slots in a plate as the snap rolls pull the stalk away, leaving only the ear and husk to enter

The altepetl included a capital that served as a religious center, the hub of distribution and organization of a local population that often lived spread out in minor settlements surrounding the capital. Altepetl was also the main source of ethnic identity for the inhabitants, even though Altepetl was frequently composed of groups speaking different languages. Each altepetl would see itself as standing in political contrast to other altepetl polities, and war

Yellow maizes derive their color from carotenoids ; red maizes are colored by anthocyanins and phlobaphenes ; and orange and green varieties may contain combinations of these pigments. Maize has short-day photoperiodism , meaning that it requires nights of a certain length to flower. Flowering further requires enough warm days above 10 °C (50 °F). The control of flowering

The accession of a new ruler in the dominant city-state was often an occasion for subjected cities to rebel by refusing to pay taxes. This meant that new rulers began their rule with a coronation campaign, often against rebellious provinces, but also sometimes demonstrating their military might by making new conquests. Motecuzoma tested
1216-584: A major uprising of the Mexica against the Spanish. During the fighting, Moctezuma was killed, either by the Spaniards who killed him as they fled the city, or by the Mexica themselves who considered him a traitor. Cuitláhuac , a kinsman and adviser to Moctezuma, succeeded him as tlatoani, mounting the defense of Tenochtitlan against the Spanish invaders and their indigenous allies. He ruled for only 80 days, perhaps dying in
1368-499: A measure of protection against a wide range of pests. Because of its shallow roots, maize is susceptible to droughts, intolerant of nutrient-deficient soils, and prone to being uprooted by severe winds. Maize is diploid with 20 chromosomes . 83% of allelic variation within the genome derives from its teosinte ancestors, primarily due to the freedom of Zea species to outcross . Barbara McClintock used maize to validate her transposon theory of "jumping genes", for which she won
1520-477: A mythical place of origin for several ethnic groups in central Mexico. The term was not used as an endonym by the Aztecs themselves, but it is found in the different migration accounts of the Mexica, where it describes the different tribes who left Aztlan together. In one account of the journey from Aztlan, Huitzilopochtli , the tutelary deity of the Mexica tribe, tells his followers on the journey that "now, no longer
1672-520: A permanent military presence, installing puppet rulers, or even moving entire populations from the center to maintain a loyal base of support. In this way, the Aztec system of government distinguished between different strategies of control in the outer regions of the empire, far from the core in the Valley of Mexico. Some provinces were treated as subject provinces, which provided the basis for economic stability for

International groups such as the Centre for Agriculture and Bioscience International consider maize the preferred common name. The word maize is used by the UN's Food and Agriculture Organization , and in the names of the International Maize and Wheat Improvement Center of Mexico, the Indian Institute of Maize Research,
1976-590: A plant that uses C 4 carbon fixation , maize is a considerably more water-efficient crop than plants that use C 3 carbon fixation such as alfalfa and soybeans . Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for pollination. In the United States, a good harvest was traditionally predicted if the maize was "knee-high by the Fourth of July ", although modern hybrids generally exceed this growth rate. Maize used for silage
2128-454: A small rabbit was worth 30 beans, a turkey egg cost three beans, and a tamal cost a single bean. For larger purchases, standardized lengths of cotton cloth, called quachtli , were used. There were different grades of quachtli, ranging in value from 65 to 300 cacao beans. About 20 quachtli could support a commoner for one year in Tenochtitlan. Another form of distribution of goods was through
2280-410: A smallpox epidemic, although early sources do not give the cause. He was succeeded by Cuauhtémoc , the last independent Mexica tlatoani, who continued the fierce defense of Tenochtitlan. The Aztecs were weakened by disease, and the Spanish enlisted tens of thousands of Indian allies, especially Tlaxcalans , for the assault on Tenochtitlan. After the siege and destruction of the Aztec capital, Cuauhtémoc
2432-428: A source of bronze tools and jewelry. On the negative side, imperial taxes imposed a burden on commoner households, who had to increase their work to pay their share of taxes. Nobles, on the other hand, often made out well under the imperial rule because of the indirect nature of imperial organization. The empire had to rely on local kings and nobles and offered them privileges for their help in maintaining order and keeping
2584-661: A strategy of exhaustion. In the Valley of Oaxaca , which was invaded Moctezuma's forces in the 1450s, the Aztec Empire would oppress the Mixtec and Zapotec peoples, who they would also require to pay tributes . Motecuzoma I also consolidated the political structure of the Triple Alliance and the internal political organization of Tenochtitlan. His brother Tlacaelel served as his main advisor (Nahuatl languages: Cihuacoatl ) and he
2736-459: A strict sumptuary code limiting the types of luxury goods that could be consumed by commoners. In 1517, Moctezuma received the first news of ships with strange warriors having landed on the Gulf Coast near Cempoallan and he dispatched messengers to greet them and find out what was happening, and he ordered his subjects in the area to keep him informed of any new arrivals. In 1519, he was informed of
2888-566: A struggle for the rulership of Azcapotzalco. During this power struggle, Chimalpopoca died, probably killed by Tezozomoc's son Maxtla who saw him as a competitor. Itzcoatl , brother of Huitzilihhuitl and uncle of Chimalpopoca, was elected the next Mexica tlatoani . The Mexica were now in open war with Azcapotzalco and Itzcoatl petitioned for an alliance with Nezahualcoyotl , son of the slain Texcocan ruler Ixtlilxochitl against Maxtla. Itzcoatl also allied with Maxtla's brother Totoquihuaztli ruler of
3040-551: A successful coronation campaign far south of Tenochtitlan against the Zapotecs in the Isthmus of Tehuantepec . Axayacatl also conquered the independent Mexica city of Tlatelolco, located on the northern part of the island where Tenochtitlan was also located. The Tlatelolco ruler Moquihuix was married to Axayacatl's sister, and his alleged mistreatment of her was used as an excuse to incorporate Tlatelolco and its important market directly under
3192-484: A system that collected human waste for use as fertilizer. Through intensive agriculture, the Aztecs were able to sustain a large urbanized population. The lake was also a rich source of proteins in the form of aquatic animals such as fish, amphibians, shrimp, insects and insect eggs, and waterfowl. The presence of such varied sources of protein meant that there was little use for domestic animals for meat (only turkeys and dogs were kept), and scholars have calculated that there

#17328589570433344-489: A way to distinguish present-day Mexicans from pre-conquest Mexicans. This usage has been the subject of debate in more recent years, but the term "Aztec" is still more common. Knowledge of Aztec society rests on several different sources: The many archeological remains of everything from temple pyramids to thatched huts can be used to understand many of the aspects of what the Aztec world was like. However, archeologists often must rely on knowledge from other sources to interpret
3496-623: A weekly market (every five days), while larger cities held markets every day. Cortés reported that the central market of Tlatelolco, Tenochtitlan's sister city, was visited by 60,000 people daily. Some sellers in the markets were petty vendors; farmers might sell some of their produce, potters sold their vessels, and so on. Other vendors were professional merchants who traveled from market to market seeking profits. The pochteca were specialized long-distance merchants organized into exclusive guilds . They made long expeditions to all parts of Mesoamerica bringing back exotic luxury goods, and they served as
3648-472: A year at differing times. Archaeological excavations in the Aztec-ruled provinces show that incorporation into the empire had both costs and benefits for provincial peoples. On the positive side, the empire promoted commerce and trade, and exotic goods from obsidian to bronze managed to reach the houses of both commoners and nobles. Trade partners also included the enemy Purépecha (also known as Tarascans),
3800-473: Is a problem in Asia. Some fungal diseases of maize produce potentially dangerous mycotoxins such as aflatoxin . In the United States, major diseases include tar spot , bacterial leaf streak , gray leaf spot , northern corn leaf blight, and Goss's wilt ; in 2022, the most damaging disease was tar spot, which caused losses of 116.8 million bushels . Maize sustains a billion dollars' worth of losses annually in
3952-408: Is composed of transposons , contains 32,540 genes. Much of it has been duplicated and reshuffled by helitrons , a group of transposable elements within maize's DNA. Maize breeding in prehistory resulted in large plants producing large ears. Modern breeding began with individuals who selected highly productive varieties in their fields and then sold seed to other farmers. James L. Reid was one of
4104-451: Is considered the architect of major political reforms in this period, consolidating the power of the noble class (Nahuatl languages: pipiltin ) and instituting a set of legal codes, and the practice of reinstating conquered rulers in their cities bound by fealty to the Mexica tlatoani. In 1469, the next ruler was Axayacatl ( lit. "Water mask"), son of Itzcoatl's son Tezozomoc and Motecuzoma I's daughter Atotoztli II . He undertook
4256-534: Is cultivated throughout the world; a greater weight of maize is produced each year than any other grain. In 2020, world production was 1.1 billion tonnes. It is afflicted by many pests and diseases ; two major insect pests, European corn borer and corn rootworms , have each caused annual losses of a billion dollars in the US. Modern plant breeding has greatly increased output and qualities such as nutrition, drought tolerance, and tolerance of pests and diseases. Much maize
4408-414: Is harvested while the plant is green and the fruit immature. Sweet corn is harvested in the "milk stage", after pollination but before starch has formed, between late summer and early to mid-autumn. Field maize is left in the field until very late in the autumn to thoroughly dry the grain, and may, in fact, sometimes not be harvested until winter or even early spring. The importance of sufficient soil moisture

4864-407: Is often known as the "Aztec Empire". The usage of the term "Aztec" in describing the empire centered in Tenochtitlan has been criticized by Robert H. Barlow , who preferred the term "Culhua-Mexica", and by Pedro Carrasco, who prefers the term "Tenochca empire". Carrasco writes about the term "Aztec" that "it is of no use for understanding the ethnic complexity of ancient Mexico and for identifying
5016-465: Is possible to talk about an "Aztec civilization" including all the particular cultural patterns common for most of the peoples inhabiting central Mexico in the late postclassic period. Such usage may also extend the term "Aztec" to all the groups in Central Mexico that were incorporated culturally or politically into the sphere of dominance of the Aztec empire. When used to describe ethnic groups ,
5168-468: Is set genetically; the physiological mechanism involves the phytochrome system. Tropical cultivars can be problematic if grown in higher latitudes, as the longer days can make the plants grow tall instead of setting seed before winter comes. On the other hand, growing tall rapidly could be convenient for producing biofuel. Immature maize shoots accumulate a powerful antibiotic substance, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one ( DIMBOA ), which provides
5320-545: Is shown in many parts of Africa, where periodic drought regularly causes maize crop failure and consequent famine . Although it is grown mainly in wet, hot climates, it can thrive in cold, hot, dry or wet conditions, meaning that it is an extremely versatile crop. Maize was planted by the Native Americans in small hills of soil, in the polyculture system called the Three Sisters . Maize provided support for beans ;
5472-543: Is the domesticated variant of the four species of teosintes , which are its crop wild relatives . The teosinte origin theory was proposed by the Russian botanist Nikolai Ivanovich Vavilov in 1931, and the American Nobel Prize -winner George Beadle in 1932. The two plants have dissimilar appearance, maize having a single tall stalk with multiple leaves and teosinte being a short, bushy plant. The difference between

The highest class was the pīpiltin or nobility. The pilli status was hereditary and ascribed certain privileges to its holders, such as the right to wear particularly fine garments and consume luxury goods, as well as to own land and direct corvee labor by commoners. The most powerful nobles were called lords (Nahuatl languages: teuctin ) and they owned and controlled noble estates or houses, and could serve in

The middle part of the short Balsas River valley is the likely location of early domestication. Stone milling tools with maize residue have been found in an 8,700 year old layer of deposits in a cave not far from Iguala, Guerrero . Doebley and colleagues showed in 2002 that maize had been domesticated only once, about 9,000 years ago, and then spread throughout

Linguistically, the term "Aztecan" is still used about the branch of the Uto-Aztecan languages (also sometimes called the Uto-Nahuan languages) that includes the Nahuatl language and its closest relatives Pochutec and Pipil . To the Aztecs themselves the word "Aztec" was not an endonym for any particular ethnic group. Rather, it was an umbrella term used to refer to several ethnic groups, not all of them Nahuatl-speaking, that claimed heritage from
6840-530: The Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. 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
6992-579: 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). The definitions of Aztec and Aztecs have long been the topic of scholarly discussion ever since German scientist Alexander von Humboldt established its common usage in
7144-446: The mācehuallis were dedicated to arts and crafts. Their works were an important source of income for the city. Macehualtin could become enslaved, (Nahuatl languages: tlacotin ) for example if they had to sell themselves into the service of a noble due to debt or poverty, but enslavement was not an inherited status among the Aztecs. Some macehualtin were landless and worked directly for a lord (Nahuatl languages: mayehqueh ), whereas
7296-532: The 13th century, the Valley of Mexico was the heart of dense population and the rise of city-states. 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. It was an empire that expanded its political hegemony far beyond the Valley of Mexico, conquering other city-states throughout Mesoamerica in

It has information naming the polities that the Triple Alliance conquered, the types of taxes rendered to the Aztec Empire, and the class/gender structure of their society. Many written annals exist, written by local Nahua historians recording the histories of their polity. These annals used pictorial histories and were subsequently transformed into alphabetic annals in Latin script. Well-known native chroniclers and annalists are Chimalpahin of Amecameca-Chalco; Fernando Alvarado Tezozomoc of Tenochtitlan; Alva Ixtlilxochitl of Texcoco, Juan Bautista Pomar of Texcoco, and Diego Muñoz Camargo of Tlaxcala. There are also many accounts by Spanish conquerors who participated in

Axayacatl was soundly defeated in a battle at Tlaximaloyan (today Tajimaroa), losing most of his 32,000 men and only barely escaping back to Tenochtitlan with the remnants of his army. In 1481 at Axayacatls death, his older brother Tizoc was elected ruler. Tizoc's coronation campaign against the Otomi of Metztitlan failed as he lost the major battle and only managed to secure 40 prisoners to be sacrificed for his coronation ceremony. Having shown weakness, many cities rebelled and consequently, most of Tizoc's short reign

This depopulation of the Bajío coincided with an incursion of new populations into the Valley of Mexico, which suggests that this marks the influx of Nahuatl speakers into the region. These people populated central Mexico, dislocating speakers of Oto-Manguean languages as they spread their political influence south. As

During this period the city-states of Tlaxcalan, Cholula and Huexotzinco emerged as major competitors to the imperial expansion, and they supplied warriors to several of the cities conquered. Motecuzoma therefore initiated a state of low-intensity warfare against these three cities, staging minor skirmishes called " Flower Wars " (Nahuatl xochiyaoyotl ) against them, perhaps as

Important for knowledge of post-conquest Nahuas was the training of indigenous scribes to write alphabetic texts in Nahuatl , mainly for local purposes under Spanish colonial rule. At its height, Aztec culture had rich and complex philosophical , mythological , and religious traditions , as well as remarkable architectural and artistic accomplishments. The Nahuatl words aztēcatl ( Nahuatl pronunciation: [asˈteːkat͡ɬ] , singular) and aztēcah ( Nahuatl pronunciation: [asˈteːkaʔ] , plural ) mean "people from Aztlán ",

10640-517: The Valley of Mexico with its many lakes and swamps permitted intensive agriculture. The main crops in addition to maize were beans, squashes, chilies, and amaranth . Particularly important for agricultural production in the valley was the construction of chinampas on the lake, artificial islands that allowed the conversion of the shallow waters into highly fertile gardens that could be cultivated year-round. Chinampas are human-made extensions of agricultural land, created from alternating layers of mud from
10792-403: The altepetl was primarily a political unit, made up of the population with allegiance to a lord, rather than as a territorial unit. He makes this distinction because in some areas minor settlements with different altepetl allegiances were interspersed. The Aztec Empire was ruled by indirect means. Like most European empires, it was ethnically very diverse, but unlike most European empires, it
10944-485: The arrival of a small group of Spanish conquistadors led by Hernán Cortés . Cortés allied with city-states opposed to the Mexica, particularly the Nahuatl-speaking Tlaxcalteca as well as other central Mexican polities, including Texcoco, its former ally in the Triple Alliance. After the fall of Tenochtitlan on 13 August 1521 and the capture of the emperor Cuauhtémoc , the Spanish founded Mexico City on
11096-433: The arrival of the Spanish fleet of Hernán Cortés, who soon marched toward Tlaxcala where he allied with the traditional enemies of the Aztecs. On 8 November 1519, Moctezuma II received Cortés and his troops and Tlaxcalan allies on the causeway south of Tenochtitlan, and he invited the Spaniards to stay as his guests in Tenochtitlan. When Aztec troops destroyed a Spanish camp on the Gulf Coast, Cortés ordered Moctezuma to execute
11248-529: The attitudes of the cities around the valley by requesting laborers for the enlargement of the Great Temple of Tenochtitlan. Only the city of Chalco refused to provide laborers, and hostilities between Chalco and Tenochtitlan would persist until the 1450s. Motecuzoma then reconquered the cities in the valley of Morelos and Guerrero, and then later undertook new conquests in the Huaxtec region of northern Veracruz, and
11400-418: The beans provided nitrogen derived from nitrogen-fixing rhizobia bacteria which live on the roots of beans and other legumes ; and squashes provided ground cover to stop weeds and inhibit evaporation by providing shade over the soil. Sweet corn, harvested earlier than maize grown for grain, grows to maturity in a period of from 60 to 100 days according to variety. An extended sweet corn harvest, picked at
11552-598: The body of Christ. Maize spread to the rest of the world because of its ability to grow in diverse climates. It was cultivated in Spain just a few decades after Columbus's voyages and then spread to Italy, West Africa and elsewhere. By the 17th century, it was a common peasant food in Southern Europe. By the 18th century, it was the chief food of the southern French and Italian peasantry, especially as polenta in Italy. When maize
11704-457: The border against the Tarascan state. Motecuhzoma Xocoyotzin is known to world history as the Aztec ruler when the Spanish invaders and their indigenous allies began their conquest of the empire in a two-year-long campaign (1519–1521). His early rule did not hint at his future fame. He succeeded in the rulership after the death of Ahuitzotl. Motecuhzoma Xocoyotzin ( lit. "He frowns like a lord,
11856-578: The bottom of the lake, and plant matter and other vegetation. These raised beds were separated by narrow canals, which allowed farmers to move between them by canoe. Chinampas were extremely fertile pieces of land, and yielded, on average, seven crops annually. Based on current chinampa yields, it has been estimated that one hectare (2.5 acres) of chinampa would feed 20 individuals and 9,000 hectares (22,000 acres) of chinampas could feed 180,000. The Aztecs further intensified agricultural production by constructing systems of artificial irrigation . While most of
12008-469: The capital to satisfy even the most conservative figures. Ahuitzotl also constructed monumental architecture in sites such as Calixtlahuaca, Malinalco, and Tepoztlan. After a rebellion in the towns of Alahuiztlan and Oztoticpac in Northern Guerrero, he ordered the entire population executed and repopulated with people from the valley of Mexico. He also constructed a fortified garrison at Oztuma defending
12160-513: The city-states on the southern lake – including Culhuacan , Xochimilco , Cuitlahuac, and Mizquic. These states had an economy based on highly productive chinampa agriculture, cultivating human-made extensions of rich soil in the shallow lake Xochimilco. Itzcoatl then undertook further conquests in the valley of Morelos , subjecting the city-state of Cuauhnahuac (today Cuernavaca ). In 1440, Moteuczomatzin Ilhuicamina ( lit. "he frowns like
12312-572: The cob on their own, while those of domesticated maize do not. All maize arose from a single domestication in southern Mexico about 9,000 years ago. The oldest surviving maize types are those of the Mexican highlands. Maize spread from this region to the lowlands and over the Americas along two major paths. The centre of domestication was most likely the Balsas River valley of south-central Mexico. Maize reached highland Ecuador at least 8000 years ago. It reached lower Central America by 7600 years ago, and
12464-454: The commanders responsible for the attack, and Moctezuma complied. At this point, the power balance had shifted toward the Spaniards who now held Moctezuma as a prisoner in his palace. As this shift in power became clear to Moctezuma's subjects, the Spaniards became increasingly unwelcome in the capital city, and, in June 1520, hostilities broke out, culminating in the massacre in the Great Temple , and
12616-439: The confederation of the Triple Alliance was formed in 1427 and began its expansion through conquest, the altepetl remained the dominant form of organization at the local level. The efficient role of the altepetl as a regional political unit was largely responsible for the success of the empire's hegemonic form of control. Like all Mesoamerican peoples, Aztec society was organized around maize agriculture. The humid environment in
12768-640: The control of the tlatoani of Tenochtitlan. Axayacatl then conquered areas in Central Guerrero, the Puebla Valley, on the gulf coast and against the Otomi and Matlatzinca in the Toluca Valley. The Toluca Valley was a buffer zone against the powerful Tarascan state in Michoacan , against which Axayacatl turned next. In the major campaign against the Tarascans (Nahuatl languages: Michhuahqueh ) in 1478–1479
12920-471: The dominant element in the political entity we are studying". In other contexts, Aztec may refer to all the various city-states and their peoples, who shared large parts of their ethnic history and cultural traits with the Mexica, Acolhua, and Tepanecs, and who often also used the Nahuatl language as a lingua franca . An example is Jerome A. Offner's Law and Politics in Aztec Texcoco . In this meaning, it
13072-425: The earliest and most successful, developing Reid's Yellow Dent in the 1860s. These early efforts were based on mass selection (a row of plants is grown from seeds of one parent), and the choosing of plants after pollination (which means that only the female parents are known). Later breeding efforts included ear to row selection (C. G. Hopkins c. 1896), hybrids made from selected inbred lines (G. H. Shull, 1909), and
13224-448: The early 19th century. Most ethnic groups of central Mexico in the post-classic period shared essential cultural traits of Mesoamerica. So many of the characteristics that characterize Aztec culture cannot be said to be exclusive to the Aztecs. For the same reason, the notion of "Aztec civilization" is best understood as a particular horizon of a general Mesoamerican civilization. The culture of central Mexico includes maize cultivation,
13376-462: The elaboration of tools and musical instruments. Sometimes entire calpollis specialized in a single craft, and in some archeological sites large neighborhoods have been found where- only a single craft specialty was practiced. The Aztecs did not produce much metalwork but did have knowledge of basic smelting technology for gold , and they combined gold with precious stones such as jade and turquoise . Copper products were generally imported from
13528-436: The empire, and strategic provinces, which were the basis for further expansion. Although the form of government is often referred to as an empire, most areas within the empire were organized as city-states, known as altepetl in Nahuatl. These were small polities ruled by a hereditary leader ( tlatoani ) from a legitimate noble dynasty. The Early Aztec period was a time of growth and competition among altepetl . Even after
13680-508: The empire. Charles Gibson enumerates many groups in central Mexico that he includes in his study The Aztecs Under Spanish Rule (1964). These include the Culhuaque, Cuitlahuaque, Mixquica, Xochimilca, Chalca, Tepaneca, Acolhuaque, and Mexica. In older usage, the term was commonly used about modern Nahuatl-speaking ethnic groups, as Nahuatl was previously referred to as the "Aztec language". In recent usage, these ethnic groups are referred to as
13832-413: The entire ear is harvested, which requires a separate operation of a maize sheller to remove the kernels from the ear. Whole ears of maize were often stored in corn cribs , sufficient for some livestock feeding uses. Today corn cribs with whole ears, and corn binders, are less common because most modern farms harvest the grain from the field with a combine harvester and store it in bins . The combine with
13984-401: The equilibrium of the world and pleasing the gods. This situation has led some scholars to describe Aztec gender ideology as an ideology not of a gender hierarchy, but of gender complementarity, with gender roles being separate but equal. Among the nobles, marriage alliances were often used as a political strategy with lesser nobles marrying daughters from more prestigious lineages whose status
14136-753: The expansion of the Inca Empire , maize was traded and transported as far south as 40° S in Melinquina, Lácar Department , Argentina, probably brought across the Andes from Chile. After the arrival of Europeans in 1492, Spanish settlers consumed maize, and explorers and traders carried it back to Europe . Spanish settlers much preferred wheat bread to maize. Maize flour could not be substituted for wheat for communion bread, since in Christian belief at that time only wheat could undergo transubstantiation and be transformed into
14288-594: The facility in 2004 to the IJNR Group headed by Robert Weisz, moving the remaining 1,000 employees to other facilities except for 6 essential employees who remain employed with RPW in Westchester County . At a cost of 40 million dollars, this was the largest real estate transaction in Westchester County in 2004 and did not include the 70 million dollar cost of renovating and subdividing the building. The complex
14440-401: The farming occurred outside the densely populated areas, within the cities there was another method of (small-scale) farming. Each family had a garden plot where they grew maize, fruits, herbs, medicines, and other important plants. When the city of Tenochtitlan became a major urban center, water was supplied to the city through aqueducts from springs on the banks of the lake, and they organized
14592-411: The former nomadic hunter-gatherer peoples mixed with the complex civilizations of Mesoamerica, adopting religious and cultural practices, the foundation for later Aztec culture was laid. After 900 CE, during the postclassic period, many sites almost certainly inhabited by Nahuatl speakers became powerful. Among them are the site of Tula, Hidalgo , and also city-states such as Tenayuca , and Colhuacan in
14744-457: The highest government positions or as military leaders. Nobles made up about five percent of the population. The second class was the mācehualtin , originally peasants, but later extended to the lower working classes in general. Eduardo Noguera estimates that in later stages only 20 percent of the population was dedicated to agriculture and food production. The other 80 percent of society were warriors, artisans, and traders. Eventually, most of
14896-532: The highly successful double cross hybrids using four inbred lines ( D. F. Jones c. 1918, 1922). University-supported breeding programs were especially important in developing and introducing modern hybrids. Since the 1940s, the best strains of maize have been first-generation hybrids made from inbred strains that have been optimized for specific traits, such as yield, nutrition, drought, pest and disease tolerance. Both conventional cross-breeding and genetic engineering have succeeded in increasing output and reducing
15048-453: The historical context of artifacts. There are many written texts by the indigenous people and Spaniards of the early colonial period that contain invaluable information about pre-colonial Aztec history. These texts provide insight into the political histories of various Aztec city-states, and their ruling lineages. Such histories were produced as well in pictorial codices . Some of these manuscripts were entirely pictorial, often with glyphs . In
15200-677: The history of the Mexica. An invaluable source of information about many aspects of Aztec religious thought, political and social structure, as well as the history of the Spanish conquest from the Mexica viewpoint is the Florentine Codex . Produced between 1545 and 1576 in the form of an ethnographic encyclopedia written bilingually in Spanish and Nahuatl, by Franciscan friar Bernardino de Sahagún and indigenous informants and scribes, it contains knowledge about many aspects of precolonial society from religion, calendrics , botany , zoology , trades and crafts and history. Another source of knowledge
15352-538: The history of the word corn in North America that "[t]o say the word corn is to plunge into the tragi-farcical mistranslations of language and history". Similar to the British usage, the Spanish referred to maize as panizo , a generic term for cereal grains, as did Italians with the term polenta . The British later referred to maize as Turkey wheat, Turkey corn, or Indian corn; Fussell comments that "they meant not
15504-412: The house, as farmers, traders, craftsmen, and warriors, whereas women were expected to take responsibility for the domestic sphere. Women could however also work outside of the home as small-scale merchants, doctors, priests, and midwives. Warfare was highly valued and a source of high prestige, but women's work was metaphorically conceived of as equivalent to warfare, and as equally important in maintaining
15656-465: The inland lake of the Basin of Mexico. The year of foundation is usually given as 1325. In 1376 the Mexica royal dynasty was founded when Acamapichtli , son of a Mexica father and a Colhua mother, was elected as the first Huey Tlatoani of Tenochtitlan. In the first 50 years after the founding of the Mexica dynasty, the Mexica were a tributary of Azcapotzalco, which had become a major regional power under
15808-521: The judges and supervisors of the Tlatelolco market. Although the economy of Aztec Mexico was commercialized (in its use of money, markets, and merchants), land and labor were not generally commodities for sale, though some types of land could be sold between nobles. In the commercial sector of the economy, several types of money were in regular use. Small purchases were made with cacao beans , which had to be imported from lowland areas. In Aztec marketplaces,
15960-488: The late post-classic period. It originated in 1427 as an alliance between the city-states Tenochtitlan, Texcoco , and Tlacopan; these allied 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
16112-419: The machinery. The combine separates the husk and the cob, keeping only the kernels. Drying is vital to prevent or at least reduce damage by mould fungi, which contaminate the grain with mycotoxins . Aspergillus and Fusarium spp. are the most common mycotoxin sources, and accordingly important in agriculture. If the moisture content of the harvested grain is too high, grain dryers are used to reduce
16264-399: The majority of commoners were organized into calpollis which gave them access to land and property. Commoners were able to obtain privileges similar to those of the nobles by demonstrating prowess in warfare. When a warrior took a captive he accrued the right to use certain emblems, weapons, or garments, and as he took more captives his rank and prestige increased. The Aztec family pattern
16416-413: The milk stage, can be arranged either by planting a selection of varieties which ripen earlier and later, or by planting different areas at fortnightly intervals. Maize harvested as a grain crop can be kept in the field a relatively long time, even months, after the crop is ready to harvest; it can be harvested and stored in the husk leaves if kept dry. Before World War II , most maize in North America
16568-427: The moisture content by blowing heated air through the grain. This can require large amounts of energy in the form of combustible gases ( propane or natural gas ) and electricity to power the blowers. Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2020, total world production was 1.16 billion tonnes , led by the United States with 31.0% of
16720-515: The mythic place of origin, Aztlan . Alexander von Humboldt originated the modern usage of "Aztec" in 1810, as a collective term applied to all the people linked by trade, custom, religion, and language to the Mexica state and the Triple Alliance . In 1843, with the publication of the work of William H. Prescott on the history of the conquest of Mexico, the term was adopted by most of the world, including 19th-century Mexican scholars who saw it as
16872-501: The need for cropland, pesticides, water and fertilizer. There is conflicting evidence to support the hypothesis that maize yield potential has increased over the past few decades. This suggests that changes in yield potential are associated with leaf angle, lodging resistance, tolerance of high plant density, disease/pest tolerance, and other agronomic traits rather than increase of yield potential per individual plant. Certain varieties of maize have been bred to produce many ears; these are
17024-400: The new crop. The rise in maize cultivation 500 to 1,000 years ago in what is now the southeastern United States corresponded with a decline of freshwater mussels , which are very sensitive to environmental changes. Because it is cold-intolerant, in the temperate zones maize must be planted in the spring. Its root system is generally shallow, so the plant is dependent on soil moisture. As
17176-445: The new temple in 1487. For the inauguration ceremony, the Mexica invited the rulers of all their subject cities, who participated as spectators in the ceremony in which an unprecedented number of war captives were sacrificed – some sources giving a figure of 80,400 prisoners sacrificed over four days. Probably the actual figure of sacrifices was much smaller, but still numbering several thousand. There have never been found enough skulls in
17328-458: The nobility, in which case they could represent their Calpolli interests in the altepetl government. In the valley of Morelos, archeologist Michael E. Smith estimates that a typical altepetl had from 10,000 to 15,000 inhabitants, and covered an area between 70 and 100 square kilometers (27 and 39 sq mi). In the Morelos Valley, altepetl sizes were somewhat smaller. Smith argues that
17480-459: The north. In the United States, maize was first cultivated at several sites in New Mexico and Arizona about 4,100 years ago. During the first millennium AD, maize cultivation spread more widely in the areas north. In particular, the large-scale adoption of maize agriculture and consumption in eastern North America took place about A.D. 900. Native Americans cleared large forest and grassland areas for
17632-515: The payment of taxes . When an altepetl was conquered, the victor imposed a yearly tax, usually paid in the form of whichever local product was most valuable or treasured. Several pages from the Codex Mendoza list subject towns along with the goods they supplied, which included not only luxuries such as feathers, adorned suits, and greenstone beads, but more practical goods such as cloth, firewood, and food. Taxes were usually paid twice or four times
17784-455: The plant gives rise to male inflorescences or tassels which produce pollen , and female inflorescences called ears . The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize relies on humans for its propagation. Since the Columbian exchange , it has become a staple food in many parts of
17936-485: The postconquest era, many other texts were written in Latin script by either literate Aztecs or by Spanish friars who interviewed the native people about their customs and stories. An important pictorial and alphabetic text produced in the early sixteenth century was Codex Mendoza , named after the first viceroy of Mexico and perhaps commissioned by him, to inform the Spanish crown about the political and economic structure of
18088-753: The presence of Starlink genetically modified corn, which had been approved only for animal consumption. The maize genus Zea is relatively closely related to sorghum , both being in the PACMAD clade of Old World grasses, and much more distantly to rice and wheat , which are in the other major group of grasses, the BOP clade . It is closely related to Tripsacum , gamagrass. various grasses e.g. fescue , ryegrass Hordeum (barley) Triticum (wheat) Oryza (rice) Pennisetum (fountaingrasses) Sorghum (sorghum) Tripsacum (gamagrass) Zea mays (maize) other Zea species ( teosintes ) Maize
18240-482: The relationship with Azcapotzalco remained close. Chimalpopoca ( lit. "She smokes like a shield"), son of Huitzilihhuitl, became ruler of Tenochtitlan in 1417. In 1418, Azcapotzalco initiated a war against the Acolhua of Texcoco and killed their ruler Ixtlilxochitl . Even though Ixtlilxochitl was married to Chimalpopoca's daughter, the Mexica ruler continued to support Tezozomoc. Tezozomoc died in 1426, and his sons began
18392-561: The ruins of Tenochtitlan. From there, they proceeded with the process of conquest and incorporation of Mesoamerican peoples into the Spanish Empire . With the destruction of the superstructure of the Aztec Empire in 1521, the Spanish used the city-states on which the Aztec Empire had been built to rule the indigenous populations via their local nobles. Those nobles pledged loyalty to the Spanish crown and converted, at least nominally, to Christianity, and, in return, were recognized as nobles by
18544-461: The ruler Tezozomoc . The Mexica supplied the Tepaneca with warriors for their successful conquest campaigns in the region and received part of the tribute from the conquered city-states. In this way, the political standing and economy of Tenochtitlan gradually grew. In 1396, at Acamapichtli's death, his son Huitzilihhuitl ( lit. "Hummingbird feather") became ruler; married to Tezozomoc's daughter,
18696-418: The social division between nobility ( pipiltin ) and commoners ( macehualtin ), a pantheon (featuring Tezcatlipoca , Tlaloc , and Quetzalcoatl ), and the calendric system of a xiuhpohualli of 365 days intercalated with a tonalpohualli of 260 days. Particular to the Mexica of Tenochtitlan was the patron god Huitzilopochtli , twin pyramids , and the ceramic styles known as Aztec I to IV. From
18848-487: The source of the " baby corn " used as a vegetable in Asian cuisine . A fast-flowering variety named mini-maize was developed to aid scientific research, as multiple generations can be obtained in a single year. One strain called olotón has evolved a symbiotic relationship with nitrogen-fixing microbes, which provides the plant with 29%–82% of its nitrogen. The International Maize and Wheat Improvement Center (CIMMYT) operates
19000-411: The southern peripheral zones of Xoconochco were not in direct contact with the center. The hegemonic nature of the Aztec empire can be seen in the fact that generally local rulers were restored to their positions once their city-state was conquered, and the Aztecs did not generally interfere in local affairs as long as the tax payments were made and the local elites participated willingly. Such compliance
19152-415: The stalk. Maize is monoecious , with separate male and female flowers on the same plant. At the top of the stem is the tassel, an inflorescence of male flowers; their anthers release pollen, which is dispersed by wind . Like other pollen, it is an allergen , but most of it falls within a few meters of the tassel and the risk is largely restricted to farm workers. The female inflorescence, some way down
19304-425: The stem from the tassel, is first seen as a silk, a bundle of soft tubular hairs , one for the carpel in each female flower, which develops into a kernel (often called a seed. Botanically, as in all grasses, it is a fruit, fused with the seed coat to form a caryopsis ) when it is pollinated. A whole female inflorescence develops into an ear or corncob , enveloped by multiple leafy layers or husks. The ear leaf
19456-487: The tax revenue flowing. Maize Maize / m eɪ z / ( Zea mays ), also known as corn in North American English , is a tall stout grass that produces cereal grain . It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte . Native Americans planted it alongside beans and squashes in the Three Sisters polyculture . The leafy stalk of
19608-598: The term maize , and the name corn is used mainly in the United States and a handful of other English-speaking countries. In countries that primarily use the term maize , the word corn may denote any cereal crop, varying geographically with the local staple , such as wheat in England and oats in Scotland or Ireland. The usage of corn for maize started as a shortening of " Indian corn " in 18th-century North America. The historian of food Betty Fussell writes in an article on
19760-404: The term "Aztec" refers to several Nahuatl-speaking peoples of central Mexico in the postclassic period of Mesoamerican chronology, especially the Mexica, the ethnic group that had a leading role in establishing the hegemonic empire based at Tenochtitlan. The term extends to further ethnic groups associated with the Aztec empire, such as the Acolhua, the Tepanec, and others that were incorporated into
19912-472: The total (table). China produced 22.4% of the global total. Many pests can affect maize growth and development, including invertebrates, weeds, and pathogens. Maize is susceptible to a large number of fungal, bacterial, and viral plant diseases . Those of economic importance include diseases of the leaf, smuts such as corn smut , ear rots and stalk rots. Northern corn leaf blight damages maize throughout its range, whereas banded leaf and sheath blight
20064-500: The two is largely controlled by differences in just two genes, called grassy tillers-1 ( gt1 , A0A317YEZ1 ) and teosinte branched-1 ( tb1 , Q93WI2 ). In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum , a related genus; this has been refuted by modern genetic testing . In 2004, John Doebley identified Balsas teosinte, Zea mays subsp. parviglumis , native to
20216-486: The valley of Mexico and Cuauhnahuac in Morelos. In the ethnohistorical sources from the colonial period, the Mexica themselves describe their arrival in the Valley of Mexico. The ethnonym Aztec (Nahuatl Aztecah ) means "people from Aztlan ", Aztlan being a mythical place of origin toward the north. Hence the term applied to all those peoples who claimed to carry the heritage from this mythical place. The migration stories of
20368-582: The valleys of the Colombian Andes between 7000 and 6000 years ago. The earliest maize plants grew a single, small ear per plant. The Olmec and Maya cultivated maize in numerous varieties throughout Mesoamerica ; they cooked, ground and processed it through nixtamalization . By 3000 years ago, maize was central to Olmec culture, including their calendar, language, and myths. The Mapuche people of south-central Chile cultivated maize along with quinoa and potatoes in pre-Hispanic times. Before
20520-443: The west. The Tepanecs of Azcapotzalco soon expelled the Mexica from Chapultepec and executed the first Aztec royal family except Queen Chimalxochitl II . In 1299, Colhuacan ruler Cocoxtli permitted them to settle in the empty barrens of Tizapan, where they were eventually assimilated into Culhuacan culture. The noble lineage of Colhuacan traced its roots back to the legendary city-state of Tula, and by marrying into Colhua families,
20672-576: The world, with the total production of maize surpassing that of wheat and rice . Much maize is used for animal feed , whether as grain or as the whole plant, which can either be baled or made into the more palatable silage . Sugar-rich varieties called sweet corn are grown for human consumption, while field corn varieties are used for animal feed, for uses such as cornmeal or masa , corn starch , corn syrup , pressing into corn oil , alcoholic beverages like bourbon whiskey , and as chemical feedstocks including ethanol and other biofuels . Maize
20824-593: The youngest child who is dead as he had lived in life but not death"), was a son of Axayacatl, and a war leader. He began his rule in standard fashion, conducting a coronation campaign to demonstrate his skills as a leader. He attacked the fortified city of Nopallan in Oaxaca and subjected the adjacent region to the empire. An effective warrior, Moctezuma maintained the pace of conquest set by his predecessor and subjected large areas in Guerrero, Oaxaca, Puebla, and even far south along
20976-403: Was Ahuitzotl ( lit. "Water monster"), brother of Axayacatl and Tizoc and war leader under Tizoc. His successful coronation campaign suppressed rebellions in the Toluca Valley and conquered Jilotepec and several communities in the northern Valley of Mexico. A second 1521 campaign to the gulf coast was also highly successful. He began an enlargement of the Great Temple of Tenochtitlan, inaugurating
21128-442: Was acquired by Philip Morris , which proceeded to lay off most of that location's employees in 1987. Then in 1989 General Foods merged with Kraft Foods Inc. to form "Kraft General Foods" where it remained in its White Plains, NY Headquarters until the mid 1990s when it moved to Northfield Illinois. After a series of subsequent mergers and restructurings, Altria , the successor to Philip Morris, sold off its remaining interest in
21280-415: Was bilateral, counting relatives on the father's and mother's side of the family equally, and inheritance was also passed both to sons and daughters. This meant that women could own property just as men and that women therefore had a good deal of economic freedom from their spouses. Nevertheless, Aztec society was highly gendered with separate gender roles for men and women. Men were expected to work outside of
21432-433: Was captured on 13 August 1521, marking the beginning of Spanish hegemony in central Mexico. Spaniards held Cuauhtémoc captive until he was tortured and executed on the orders of Cortés, supposedly for treason, during an ill-fated expedition to Honduras in 1525. His death marked the end of a tumultuous era in Aztec political history. After the fall of the Aztec Empire, entire Nahua communities were subject to forced labor under
21584-458: Was harvested by hand. This involved a large number of workers and associated social events (husking or shucking bees ). From the 1890s onward, some machinery became available to partially mechanize the processes, such as one- and two-row mechanical pickers (picking the ear, leaving the stover ) and corn binders, which are reaper-binders designed specifically for maize. The latter produce sheaves that can be shocked . By hand or mechanical picker,
21736-553: Was inhabited by speakers of Nahuatl, or whether Nahuas had not yet arrived in central Mexico in the classic period. It is generally agreed that the Nahua peoples were not indigenous to the highlands of central Mexico, but that they gradually migrated into the region from somewhere in northwestern Mexico. At the fall of Teotihuacan in the 6th century CE, some city-states rose to power in central Mexico, some of them, including Cholula and Xochicalco, probably inhabited by Nahuatl speakers. One study has suggested that Nahuas originally inhabited
21888-425: Was introduced into Western farming systems, it was welcomed for its productivity. However, a widespread problem of malnutrition soon arose wherever it had become a staple food . Indigenous Americans had learned to soak maize in alkali -water — made with ashes and lime — since at least 1200–1500 BC, creating the process of nixtamalization. They did this to liberate the corn hulls, but coincidentally it also liberated
22040-479: Was more of a hegemonic confederacy than a single system of government. Ethnohistorian Ross Hassig has argued that the Aztec empire is best understood as an informal or hegemonic empire because it did not exert supreme authority over the conquered lands; it merely expected taxes to be paid and exerted force only to the degree it was necessary to ensure the payment of taxes. It was also a discontinuous empire because not all dominated territories were connected; for example,
22192-413: 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,
22344-503: Was no shortage of protein among the inhabitants of the Valley of Mexico. The excess supply of food products allowed a significant portion of the Aztec population to dedicate themselves to trades other than food production. Apart from taking care of domestic food production, women weaved textiles from agave fibers and cotton . Men also engaged in craft specializations such as the production of ceramics and obsidian and flint tools and of luxury goods such as beadwork , featherwork , and
22496-466: Was one of the 26 genetically engineered food crops grown commercially in 2016. The vast majority of this is Bt maize . Genetically modified maize has been grown since 1997 in the United States and Canada; by 2016, 92% of the US maize crop was genetically modified. As of 2011, herbicide-tolerant maize and insect-resistant maize varieties were each grown in over 20 countries. In September 2000, up to $ 50 million worth of food products were recalled due to
22648-439: Was secured by establishing and maintaining a network of elites, related through intermarriage and different forms of exchange. Nevertheless, the expansion of the empire was accomplished through military control of frontier zones, in strategic provinces where a much more direct approach to conquest and control was taken. Such strategic provinces were often exempt from taxation. The Aztecs even invested in those areas, by maintaining
22800-475: Was spent attempting to quell rebellions and maintain control of areas conquered by his predecessors. Tizoc died suddenly in 1485, and it has been suggested that he was poisoned by his brother and war leader Ahuitzotl who became the next tlatoani. Tizoc is mostly known as the namesake of the Stone of Tizoc a monumental sculpture (Nahuatl temalacatl ), decorated with a representation of Tizoc's conquests. The next ruler
22952-402: Was then inherited by their children. Nobles were also often polygamous, with lords having many wives. Polygamy was not very common among the commoners and some sources describe it as being prohibited. The main unit of Aztec political organization was the city-state, in Nahuatl called the altepetl , meaning "water-mountain". Each altepetl was led by a ruler, a tlatoani , with authority over
23104-405: Was waged between altepetl states. In this way, Nahuatl-speaking Aztecs of one Altepetl would be solidary with speakers of other languages belonging to the same altepetl, but enemies of Nahuatl speakers belonging to other competing altepetl states. In the basin of Mexico, altepetl was composed of subdivisions called calpolli , which served as the main organizational unit for commoners. In Tlaxcala and
