Nahuatl languages
–
The Nahuan or Aztecan languages are those languages of the Uto-Aztecan language family that have undergone a sound change, known as Whorfs Law, that changed an original *t to /tɬ/ before *a. Subsequently, some Nahuan languages have changed this /tɬ/ to /l/ or back to /t/, the best known Nahuan language is Nahuatl. As of 2008, the Mexican government recognizes thirty varieties that are spoken in Mexico as languages, Nahuan languages include not just varieties known as Nahuatl, but also Pipil and the extinct Pochutec language. The distinction between the Nahuatl and Pochutec is now thought to be due to contact, see Pochutec language for details. Thus, by that criterion, they could be considered different languages, the ISO divisions referenced below respond to intelligibility more than to historical or reconstructional considerations. Like the higher-level groupings, they also are not self-evident and are subject to considerable controversy and this binary division of Aztecan was already the majority opinion among specialists, but Campbell and Langackers new arguments were received as being compelling. Furthermore, in adopt the term General Aztec, they may in fact have been the ones to introduce this designation, part of their reconstruction of the Proto-Aztecan vowels was disputed by Dakin. She shows that verbs in -oa and -ia are historically and grammatically distinct from verbs in -iya and -owa and she also explains the historical development of the applicative suffix with the shape -lia and -lwia as coming from a single suffix of the shape -liwa. Dakin has proposed a historical internal classification of Nahuan, e. g. Dakin and she asserts two groups of migrations in central Mexico and eventually southwards to Central America. Centuries later, the group of migrations produced Western dialects. But many modern dialects are the result of blending between particular Eastern dialects and particular Western dialects, Campbell in his grammar of Pipil discussed the problem of classifying Pipil. Pipil is either a descendant of Nahuatl or still to this day a variety of Nahuatl, Dakin is a book-length study of the phonological evolution of Proto-Nahuatl. Dakin suggested that irregularities in the modern Nahuatl system of possessive prefixes might be due to the presence in Proto-Nahuan of distinct grammatical marking for two types of possession. In the 1990s, two papers appeared addressing the old problem of the saltillo in Nahuatl, a lost paper by Whorf. A Center-Periphery scheme was introduced by Canger in 1978, and supported by historical data in 1980. Lastra de Suarez dialect atlas that divided dialects into center and peripheral areas based on strictly synchronic evidence, the subsequent 1988 article by Canger adduced further historical evidence for this division. Until the middle of the 20th century, scholarship on Nahuan languages was limited almost entirely to the language that existed approximately 1540–1770. Since the 1930s, there have appeared several grammars of modern dialects

Aztec
–
The Aztec people were certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to 16th centuries. The Nahuatl words aztecatl and aztecah mean people from Aztlan, a place for the Nahuatl-speaking culture of the time. Often the term Aztec refers exclusively to the Mexica people of Tenochtitlan, situated on an island in Lake Texcoco, who referred to themselves as Mēxihcah Tenochcah or Cōlhuah Mexihcah. From the 13th century, the Valley of Mexico was the heart of Aztec civilization, here the capital of the Aztec Triple Alliance, the Triple Alliance formed a tributary empire expanding its political hegemony far beyond the Valley of Mexico, conquering other city states throughout Mesoamerica. At its pinnacle, Aztec culture had rich and complex mythological and religious traditions, as well as achieving remarkable architectural and artistic accomplishments. Subsequently, the Spanish founded the new settlement of Mexico City on the site of the ruined Aztec capital, the term extends to further ethnic groups associated with the Aztec empire such as the Acolhua and Tepanec and others that were incorporated into the empire. In older usage the term was used about modern Nahuatl speaking ethnic groups. In recent usage these ethnic groups are referred to as the Nahua peoples. Linguistically the term Aztecan is still used about the branch of the Uto-Aztecan languages that includes the Nahuatl language and its closest relatives Pochutec, to the Aztecs themselves the word aztec was not an endonym for any particular ethnic group. Rather it was a term used to refer to several ethnic groups, not all of them Nahuatl speaking. In the Nahuatl language aztecatl means person from Aztlan and this usage has been the subject of debate in more recent years, but the term Aztec is still more common. For the same reason the notion of Aztec civilization is best understood as a horizon of a general Mesoamerican civilization. Particular to the Aztecs of Tenochtitlan was the Mexica patron God Huitzilopochtli, twin pyramids, the Aztec Empire was a tribute empire based in Tenochtitlan that extended its power throughout Mesoamerica in the late postclassic period. Soon Texcoco and Tlacopan became junior partners in the alliance, which was de facto led by the Mexica of Tenochtitlan, the empire extended its power by a combination of trade and military conquest. The political clout of the empire reached far south into Mesoamerica conquering cities as far south as Chiapas and Guatemala, the Nahua peoples began to migrate into Mesoamerica from northern Mexico in the 6th century. They populated central Mexico, dislocating speakers of Oto-Manguean languages as they spread their influence south. As the former nomadic hunter-gatherer peoples mixed with the civilizations of Mesoamerica, adopting religious and cultural practices. During the Postclassic period they rose to power at such sites as Tula, in the 12th century the Nahua power center was in Azcapotzalco, from where the Tepanecs dominated the valley of Mexico

Mexica
–
The Mexica or Mexicas were an indigenous people of the Valley of Mexico, known today as the rulers of the Aztec Empire. The Mexica were a Nahua people who founded their two cities Tenochtitlan and Tlatelolco on raised islets in Lake Texcoco around AD1300, after the rise of the Aztec Triple Alliance, the Tenochca Mexica assumed a senior position over their two allied cities, Texcoco and Tlacopan. The Mexica are eponymous of the placename Mexico Mēxihco and this area was expanded upon in the wake of the Spanish conquest and administered from the former Aztec capital as New Spain. Like many of the peoples around them, the Mexica spoke Nahuatl, the form of Nahuatl used in the 16th century, when it began to be written in the alphabet brought by the Spanish, is known as Classical Nahuatl. Nahuatl is still today by over 1.5 million people

Tenochtitlan
–
Mexico-Tenochtitlan, commonly known as Tenochtitlan was a Mexica located on an island in Lake Texcoco, in the Valley of Mexico. Founded on June 20,1325, it became the capital of the expanding Aztec Empire in the 15th century, at its peak it was the largest city in the Pre-Columbian Americas. It subsequently became a cabecera of the Viceroyalty of New Spain, today the ruins of Tenochtitlan are located in Mexico Citys downtown. Tenochtitlan was one of two Nahua āltēpetl on the island, the other being Tlatelolco, traditionally, the name Tenochtitlan was thought to come from Nahuatl tetl and nōchtli and is often thought to mean, Among the prickly pears rocks. However, one attestation in the late 16th-century manuscript known as the Bancroft dialogues suggest the second vowel was short, Tenochtitlan covered an estimated 8 to 13.5 km2, situated on the western side of the shallow Lake Texcoco. At the time of Spanish conquests, Mexico City comprised both Tenochtitlan and Tlatelolco, the city was connected to the mainland by causeways leading to the north, south, and west. The causeways were interrupted by bridges that allowed canoes and other traffic to pass freely. The bridges could be pulled away, if necessary, to defend the city, the city was interlaced with a series of canals, so that all sections of the city could be visited either on foot or via canoe. Lake Texcoco was the largest of five interconnected lakes, since it formed in an endorheic basin, Lake Texcoco was brackish. During the reign of Moctezuma I, the levee of Nezahualcoyotl was constructed, estimated to be 12 to 16 km in length, the levee was completed circa 1453. The levee kept fresh spring-fed water in the waters around Tenochtitlan and kept the brackish waters beyond the dike, two double aqueducts, each more than 4 km long and made of terracotta, provided the city with fresh water from the springs at Chapultepec. This was intended mainly for cleaning and washing, for drinking, water from mountain springs was preferred. Most of the population liked to bathe twice a day, Moctezuma was said to take four baths a day. According to the context of Aztec culture in literature, the soap that they most likely used was the root of a plant called copalxocotl, and to clean their clothes they used the root of metl. Also, the classes and pregnant women washed themselves in a temazcalli, similar to a sauna bath. This was also popular in other Mesoamerican cultures, and some of our soldiers even asked whether the things that we saw were not a dream. I do not know how to describe it, seeing things as we did that had never heard of or seen before. The city was divided into four zones, or campan, each campan was divided into 20 districts, there were three main streets that crossed the city, each leading to one of the three causeways to the mainland of Tepeyac, Ixtapalpa, and Tlacopan

Chicomoztoc
–
Culhuacan was viewed as a prestigious and revered place by the Aztec/Mexica. In Aztec codical writing, the symbol or glyph representing the toponym of Culhuacan took the form of a bent or curved hill, the purported existence of actual underground caves plays a role in New Age Mayanism. In the State of Guanajuato the highest mountain is El Cerro de Culiacán and is surrounded by all the signs that correspond to the measure and chronicles of the legendary Chicomoztoc. In Clive Cusslers novel Lost Empire, Chicomoztoc is discovered to be an island in South Sulawesi, Indonesia, shamanism James E. Brady, Keith M. Prufer.

Acolhua
–
The Acolhua are a Mesoamerican people who arrived in the Valley of Mexico in or around the year 1200 CE. The Acolhua were a culture of the Aztecs as well as the Tepanec, Chalca, Xochimilca. It is likely that the family of the Acolhua were descended from Otomi speakers. Under Techotlalatzins grandson, Nezahualcoyotl, the Acolhua allied with the Mexica in the Aztec Triple Alliance, the Acolhua capital, Texcoco, became a cultural center of the resultant Aztec Empire

Tlaxcala (Nahua state)
–
Tlaxcala was a pre-Columbian city and state in central Mexico. The Tlaxcalans arrived in Central Mexico during the Late Postclassic and they first settled near Texcoco in the valley of Mexico, between the settlement of Cohuatlinchan and the shore of Lake Texcoco. After some years the Tlaxcallans were driven out of the valley of Mexico and moved to the east, over the subsequent years, the Tlaxcallan state expanded with the foundations of Ocotelulco and Tizatlán. The fourth major settlement, Quiahuiztlan, was founded by members of the Tlaxcallan group that had remained in the valley of Mexico. Ancient Tlaxcala was a republic ruled by a council of between 50 and 200 chief political officials and these officials gained their positions through service to the state, usually in warfare, and as a result came from both the noble and commoner classes. Tlaxcala was never conquered by the Aztec empire, but was engaged in a state of perpetual war, as a result of their alliance with the Spaniards, Tlaxcala had hidalgo privileged status within Spanish colonial Mexico. After the Spanish conquered Tenochtitlan and the rest of Mexico, Tlaxcala was allowed to survive and preserve its pre-Columbian culture. In addition, as a reward to the Tlaxcalans unyielding loyalty to the Spanish, conquistador Bernal Díaz del Castillo describes the first battle between the Spanish force and the Tlaxcalteca as surprisingly difficult. Xicohtencatl the Younger was later condemned by the Tlaxcaltecan ruling council, due to protracted warfare between the Aztecs and the Tlaxcala, the Tlaxcala were eager to exact revenge, and soon became loyal allies of the Spanish. Even after the Spanish were expelled from Tenochtitlan, the Tlaxcala continued to support their conquest, Tlaxcala also assisted the Spanish in the conquest of Guatemala. Following the Spanish Conquest, Tlaxcala was divided into four fiefdoms by the Spanish corregidor Gómez de Santillán in 1545 and these fiefdoms were Ocotelolco, Quiahuiztlan, Tepeticpac, and Tizatlan. At this time, four houses or lineages emerged and claimed hereditary rights to each fiefdom. During the colonial period, the Tlaxcalan people were regarded as being of higher status, however, the indigenous population who had been living in Tlaxcala were reduced to a small minority. It was painted by Tlaxcalteca artists under Spanish supervision, crónica Mexicayotl was written by Fernando Alvarado Tezozomoc, in Nahuatl and Spanish, in the last decades of the 16th century.

Tepanec
–
The Tepanecs or Tepaneca are a Mesoamerican people who arrived in the Valley of Mexico in the late 12th or early 13th centuries. The Tepanec were a culture of the Aztecs as well as the Acolhua and others—these tribes spoke the Nahuatl language and shared the same general pantheon. Reputedly welcomed to the Valley of Mexico by the semi-legendary Chichimeca ruler Xolotl, under their tlatoani, Acolnahuacatl, the Tepanec took over Azcapotzalco from the indigenous inhabitants. In the early 14th century, Tezozomoc brought the Tepanec to their height of power, at that point they controlled all of the Valley of Mexico as well as parts of the Toluca. Native sources say that Tezozomoc lived to the age of over 100 and was legendary for his generalship and statesmanship, the death of Tezozomoc in 1426 brought his sons Tayatzin and Maxtla to the throne, with Maxtla most likely poisoning Tayatzin. In 1428, Maxtla was overthrown by the nascent Aztec Triple Alliance, which included the Mexicas of Tenochtitlan, with the rise of the Aztec empire, Tlacopan became the predominant Tepanec city, although both Tenochtitlan and Texcoco eclipsed Tlacopan in size and prestige

Aztec codices
–
Aztec codices are books written by pre-Columbian and colonial-era Aztecs. These codices provide some of the best primary sources for Aztec culture, the pre-Columbian codices mostly do not in fact use the codex form and are, or originally were, long folded sheets. They also differ from European books in that they mostly consist of images and pictograms, the colonial era codices not only contain Aztec pictograms, but also Classical Nahuatl, Spanish, and occasionally Latin. Some are entirely in Nahuatl without pictorial content, although there are very few surviving pre-conquest codices, the tlacuilo tradition endured the transition to colonial culture, scholars now have access to a body of around 500 colonial-era codices. Colonial-era Nahuatl language documentation is the texts of the New Philology. The Codex Borbonicus is a written by Aztec priests around the time of the Spanish conquest of Mexico. Like all pre-Columbian Aztec codices, it was pictorial in nature. Codex Bornobicus is held at the Library of the National Assembly of France, the Boturini Codex was painted by an unknown Aztec author some time between 1530 and 1541, roughly a decade after the Spanish conquest of Mexico. Pictorial in nature, it tells the story of the legendary Aztec journey from Aztlán to the Valley of Mexico, rather than employing separate pages, the author used one long sheet of amatl, or fig bark, accordion-folded into 21½ pages. There is a rip in the middle of the 22nd page, unlike many other Aztec codices, the drawings are not colored, but rather merely outlined with black ink. Also known as Tira de la Peregrinación, it is named one of its first European owners. It is now held in the Museo Nacional de Antropología in Mexico City, the Codex Mendoza is a pictorial document, with Spanish annotations and commentary, composed circa 1541. It is divided into three sections, a history of each Aztec ruler and their conquests, a list of the tribute paid by each province. It is held in the Bodleian Library at the University of Oxford, the Florentine Codex is a set of 12 books created under the supervision of Bernardino de Sahagún between approximately 1540 and 1585. It is a copy of original materials which are now lost. Perhaps more than any source, the Florentine Codex has been the major source of Aztec life in the years before the Spanish conquest. Anderson published English translations of the Nahuatl text of the books in separate volumes. A full color, facsimile copy of the codex was published in three bound volumes in 1979

Huitzilopochtli
–
In the Aztec religion, Huitzilopochtli, is a Mesoamerican deity of war, sun, human sacrifice and the patron of the city of Tenochtitlan. He was also the god of the Mexicas, also known as Aztecs. Many in the pantheon of deities of the Aztecs were inclined to have a fondness for an aspect of warfare. However, Huitzilopochtli was known as the god of war in ancient Mexico. Since he was the god of the Mexica, he was credited with both the victories and defeats that the Mexica people had on the battlefield. The people had to make sacrifices to him to protect the Aztec from infinite night and it is important to remember that the defeat of their patron deity meant the defeat of his people. This is one of the reasons why they were concerned with providing exquisite tribute. Not only was it important for him to survive his battles and he wielded Xiuhcoatl as a weapon, associating him with fire. The name literally means something like Hummingbird South or Hummingbird Left, in the tlaxotecuyotl, a hymn sung in reverence to Huitzilopotchtli, he is referred to as, the Dart-Hurler, the divine hurler, and a terror to the Mixteca. There are a handful of origin mythologies describing the deity’s beginnings, one story tells of the cosmic creation and Huitzilopochtli’s role. According to this legend, he was the smallest son of parents being the creator couple Tonacatecutli and Tonacacihuatl while his brothers were Quetzalcoatl. His mother and father instructed him and Quetzalcoatl to bring order to the world. And so, together they made fire, the first male and female humans, created the Earth, another origin story tells of a fierce goddess, Coatlicue, being impregnated as she was sweeping by a ball of feathers on Mount Coatepec. Her other children, who were fully grown, were the four hundred male Centzonuitznaua. These children, angered by the manner by which their mother became impregnated, conspired to kill her, Huitzilopochtli burst forth from his mother’s womb in full armor and fully grown. He attacked his brothers and sister, defending his mother by beheading his sister. He also chased after his brothers, who fled from him, Huitzilopochtli is seen as the sun in mythology, while his many male siblings are perceived as the stars and his sister as the moon. In the Aztec worldview, this is the reason why the Sun is constantly chasing the Moon and it is also why it was so important to provide tribute and thus sustenance for Huitzilopochtli, and thus the sun

Alexander von Humboldt
–
Friedrich Wilhelm Heinrich Alexander von Humboldt was a Prussian geographer, naturalist, explorer, and influential proponent of Romantic philosophy and science. He was the brother of the Prussian minister, philosopher. Humboldts quantitative work on botanical geography laid the foundation for the field of biogeography, Humboldts advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in Latin America and his description of the journey was written up and published in an enormous set of volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined and this important work also motivated a holistic perception of the universe as one interacting entity. Alexander von Humboldt was born in Berlin in Prussia on 14 September 1769 and he was baptized as a baby in the Lutheran faith, with the Duke of Brunswick serving as godfather. At age 42, Alexander Georg was rewarded for his services in the Seven Years War with the post of Royal Chamberlain and he profited from the contract to lease state lotteries and tobacco sales. He first married the daughter of Prussian General Adjutant Schweder, in 1766, Alexander Georg married Maria Elisabeth Colomb, a well-educated woman and widow of Baron Hollwede, with whom she had a son. Alexander Georg and Maria Elisabeth had three children, a daughter, who died young, and then two sons, Wilhelm and Alexander and her first-born son, Wilhelms and Alexanders half-brother, was something of a neer do well, not often mentioned in the family history. Alexander Georg died in 1779, leaving the brothers Humboldt in the care of their emotionally distant mother, Humboldts mother expected them to become civil servants of the Prussian state. The money Baron Holwede left to Alexanders mother became, after her death, instrumental in funding Alexanders explorations, due to his youthful penchant for collecting and labeling plants, shells and insects, Alexander received the playful title of the little apothecary. On April 25,1789, he matriculated at Göttingen, then known for the lectures of C. G. Heyne and his brother Wilhelm was already a student at Göttingen, but they did not interact much since their intellectual interests were quite different. His vast and varied interests were by this time fully developed, at Göttingen he met Georg Forster, a naturalist who had been with Captain James Cook on his second voyage. Humboldt traveled with Forster in Europe, the two traveled to England, Humboldts first sea voyage, The Netherlands, and France. In England, he met Sir Joseph Banks, President of the Royal Society, the scientific friendship between Banks and Humboldt lasted until Bankss death in 1820, and the two shared botanical specimens for study. Banks also mobilized his scientific contacts in later years to aid Humboldts work, Humboldts scientific excursion up the Rhine resulted in his 1790 treatise Mineralogische Beobachtungen über einige Basalte am Rhein. Humboldts passion for travel was of long standing, Humboldts talents were devoted to the purpose of preparing himself as a scientific explorer. During this period, his brother Wilhelm married, but Alexander did not attend the nuptials, Humboldt graduated from the Freiberg School of Mines in 1792 and was appointed to a Prussian government position in the Department of Mines as an inspector in Bayreuth and the Fichtel mountains

William H. Prescott
–
William Hickling Prescott was an American historian and Hispanist, who is widely recognized by historiographers to have been the first American scientific historian. Despite suffering from serious visual impairment, which at times prevented him from reading or writing for himself and he is also noted for his eidetic memory. After an extensive period of study, during which he contributed to academic journals, Prescott specialized in late Renaissance Spain. During his lifetime, he was upheld as one of the greatest living American intellectuals, Prescott has become one of the most widely translated American historians, and was an important figure in the development of history as a rigorous academic discipline. Historians admire Prescott for his exhaustive, careful, and systematic use of archives, his accurate recreation of sequences of events, his balanced judgments and his lively writing style. He was primarily focused on political and military affairs, largely ignoring economic, social, intellectual, instead, he wrote narrative history, subsuming unstated causal forces in his driving storyline. William H. Prescott was born in Salem, Massachusetts on May 4,1796 and his parents were William Prescott, Jr. a lawyer, and his wife, née Catherine Greene Hickling. His grandfather William Prescott served as a colonel during the American Revolutionary War, Prescott began formal schooling at the age of seven, studying under Mr. Jacob Knapp. The family moved to Boston, Massachusetts in 1808, where his fathers earnings substantially increased and his studies continued under Dr. John Gardiner, rector of Trinity Episcopal Church. As a young man, Prescott frequented the Boston Athenæum, which at the held the 10, 000-volume private library of John Quincy Adams. In 1832, Prescott became a trustee of the library, a position he held for 15 years, Prescott enrolled at Harvard College as a second year student in August 1811, at the age of 15. He was not considered academically distinguished, despite showing promise in Latin, Prescotts eyesight degenerated after being hit in the eye with a crust of bread during a food fight as a student, and it remained weak and unstable throughout the rest of his life. Prescott was admitted to the Phi Beta Kappa Society as a senior, which he considered a personal honor. After a short period of illness, he embarked on an extended tour of Europe. Prescott first traveled to the island of São Miguel in the Azores, after two weeks, he left for the cooler climate of London, where he stayed with the distinguished surgeon Astley Cooper and the oculist William Adams. Prescott first used a noctograph while staying with Adams, the became a permanent feature of his life. He visited Hampton Court Palace with future American president John Quincy Adams, at the time a diplomat in London, in August 1816, Prescott traveled to Paris, but later moved on to Italy, where he spent the winter. He returned to Paris in early 1817, where he chanced to meet the American Hispanist George Ticknor, Prescott spent some time in Cambridge, where he saw the manuscripts of Isaac Newtons works, and returned to the United States in the same year

Human migration
–
Human migration is the movement by people from one place to another with the intentions of settling, permanently in the new location. The movement is often long distances and from one country to another, but internal migration is also possible, indeed. Migration may be individuals, family units or in large groups, nomadic movements are normally not regarded as migrations as there is no intention to settle in the new place and because the movement is generally seasonal. Only a few people have retained this form of lifestyle in modern times. Many estimates of statistics in worldwide migration patterns exist, the World Bank has published its Migration and Remittances Factbook annually since 2008. The International Organisation for Migration has published a yearly World Migration Report since 1999, the United Nations Statistics Division also keeps a database on worldwide migration. Recent advances in research on migration via the Internet promise better understanding of migration patterns, substantial internal migration can also take place within a country, either seasonal human migration, or shifts of population into cities or out of cities. Studies of worldwide migration patterns, however, tend to limit their scope to international migration, the World Banks Migration and Remittances Factbook of 2011 lists the following estimates for the year 2010, total number of immigrants,215.8 million or 3. 2% of world population. In 2013, the percentage of international migrants worldwide increased by 33% with 59% of migrants targeting developed regions, almost half of these migrants are women, which is one of the most significant migrant-pattern changes in the last half century. Women migrate alone or with their members and community. Even though female migration is largely viewed as rather than independent migration, emerging studies argue complex. The World Banks report estimates that, as of 2010,16.3 million or 7. 6% of migrants qualified as refugees. At the end of 2012, approximately 15.4 million people were refugees, structurally, there is substantial South-South and North-North migration, i. e. most emigrants from high-income O. E. C. D. Countries migrate to other countries, and a substantial part of emigrants from developing countries migrate to other developing countries. Between 2000 and 2013 the average rate of change of the migrant population in the developing regions slightly exceeded that of the developed regions. Remittances, i. e. funds transferred by migrant workers to their home country, the top ten remittance recipients in 2010 were 1. China, Mexico, Philippines, France, Germany, Bangladesh, Belgium, Spain, the Global Commission on International Migration, launched in 2003, published a report in 2005. International migration challenges at the level are addressed through the Global Forum on Migration and Development

Crab Nebula
–
The Crab Nebula is a supernova remnant in the constellation of Taurus. The now-current name is due to William Parsons, 3rd Earl of Rosse, corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a supernova explosion. At an apparent magnitude of 8.4, comparable to that of Saturns moon Titan, it is not visible to the naked eye, the nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 2.0 kiloparsecs from Earth. It has a diameter of 3.4 parsecs, corresponding to an apparent diameter of some 7 arcminutes, and is expanding at a rate of about 1,500 kilometres per second, or 0. 5% of the speed of light. At the center of the lies the Crab Pulsar, a neutron star 28–30 kilometres across with a spin rate of 30.2 times per second. At X-ray and gamma ray energies above 30 keV, the Crab Nebula is generally the strongest persistent source in the sky, the nebulas radiation allows for the detailed studying of celestial bodies that occult it. The inner part of the nebula is a much smaller pulsar wind nebula that appears as a shell surrounding the pulsar, for the Crab Nebula, the divisions are superficial but remain meaningful to researchers and their lines of study. Modern understanding that the Crab Nebula was created by a supernova dates to 1921 and this eventually led to the conclusion that the creation of the Crab Nebula corresponds to the bright SN1054 supernova recorded by Chinese astronomers in AD1054. There is also a 13th-century Japanese reference to this guest star in Meigetsuki, the Crab Nebula was first identified in 1731 by John Bevis. The nebula was independently rediscovered in 1758 by Charles Messier as he was observing a bright comet and it is in searching in vain for the comet that Charles Messier found the Crab nebula, which he at first thought to be Halleys comet. After some observation, noticing that the object that he was observing was not moving across the sky, Messier then realised the usefulness of compiling a catalogue of celestial objects of a cloudy nature, but fixed in the sky, to avoid incorrectly cataloguing them as comets. After several observations, he concluded that it was composed of a group of stars. The 3rd Earl of Rosse observed the nebula at Birr Castle in 1844 using a 36-inch telescope and he observed it again later, in 1848, using a 72-inch telescope and could not confirm the supposed resemblance, but the name stuck nevertheless. In 1913, when Vesto Slipher registered his spectroscopy study of the sky, in the early twentieth century, the analysis of early photographs of the nebula taken several years apart revealed that it was expanding. Tracing the expansion back revealed that the nebula must have become visible on Earth about 900 years ago, historical records revealed that a new star bright enough to be seen in the daytime had been recorded in the same part of the sky by Chinese astronomers in 1054. Changes in the cloud, suggesting its small extent, were discovered by Carl Lampland in 1921 and that same year, John Charles Duncan demonstrated that the remnant is expanding, while Knut Lundmark noted its proximity to the guest star of 1054.5 by July. The supernova was visible to the eye for about two years after its first observation

City-state
–
A city-state is a sovereign state that consists of a city and its dependent territories. A great deal of consensus exists that the term applies to Singapore, Monaco. A number of small states share similar characteristics, and therefore are sometimes also cited as modern city-states. Occasionally, other states with high population densities, such as San Marino, are also cited. Several non-sovereign cities enjoy a degree of autonomy, and are sometimes considered city-states. Hong Kong and Macau, along with independent members of the United Arab Emirates, most notably Dubai, scholars have classed the Viking colonial cities in medieval Ireland, most importantly Dublin, as city-states. In Cyprus, the Phoenician settlement of Kition was a city-state that existed from around 800 BC until the end of the 4th century BC. The success of regional units coexisting as autonomous actors in loose geographical and cultural unity, as in Italy and Greece. However, such small political entities often survived only for short periods because they lacked the resources to defend themselves against incursions by larger states, thus they inevitably gave way to larger organisations of society, including the empire and the nation-state. In the history of Mainland Southeast Asia, aristocratic groups, Buddhist leaders, the system existed until the 19th century when colonization by European powers, and Thailands resulted in the adoption of the modern concept of statehood. In the Holy Roman Empire the Free Imperial Cities enjoyed a considerable autonomy, some, like the three Hanseatic cities of Bremen, Hamburg and Lübeck, pooled their economic relations with foreign powers and were able to wield considerable diplomatic clout. Under Habsburg rule the city of Fiume had the status of a Corpus separatum, a later city-state, though lacking sovereignty, was West Berlin, being a state legally not belonging to any other state, but ruled by the Western Allies. They allowed – notwithstanding their overlordship as occupant powers – its internal organisation as one state simultaneously being a city, though West Berlin maintained close ties to the West German Federal Republic of Germany, it was legally never part of it. But the idea of leaving the United States proved too radical even in the turmoil of 1861 and was poorly received, the war, and especially conscription, was nevertheless often unpopular in the city, sparking the deadly New York Draft Riots. The neighboring City of Brooklyn, in contrast, was staunchly Unionist, the Free City of Danzig was a semi-autonomous city-state that existed between 1920 and 1939, consisting of the Baltic Sea port of Danzig and nearly 200 towns in the surrounding areas. It was created on 15 November 1920 under the terms of Article 100 of the 1919 Treaty of Versailles after the end of World War I. Its territory of 28 km2 comprised the city of Fiume and rural areas to its north, with a corridor to its west connecting it to Italy, the Shanghai International Settlement was an international zone with its own legal system, postal service, and currency. The Klaipėda Region or Memel Territory was defined by the Treaty of Versailles in 1920 when it was put under the administration of the Council of Ambassadors

Tecpatl
–
In the Aztec culture, a tecpatl was a flint or obsidian knife with a lanceolate figure and double-edged blade, with elongated ends. Both ends could be rounded or pointed, but other designs were made with an attached to a handle. It can be represented with the top half red, reminiscent of the color of blood, in representations of human sacrifice and the rest white, indicating the color of the flint blade. It was the sign of the day, the twentieth day of the month of the Aztec calendar. The Tecpatl knife was used for human sacrifice by the Aztecs. Although it may have only limited use on the battlefield. Tecpatl, is one of the most complex iconographic symbols of Aztec mythology and this knife expresses multiple meanings that carry a complex view of the world which are closely associated with the notions of origin and human sacrifice. The Tecpatl was born in the height of heaven shaped as a knife, and was thrown down by his brother, and it was destined to descend from heaven to earth. It falls in Chicomoztoc primary array of peoples, fragmenting into 1600 pieces, and from those fragments a thousand and six hundred gods emerge and these gods emerging from the Seven Caves are the Centzonmimixcoa. Then they went into a cave, and upon entering, their mother gave birth to five more Mimixcoa. In the version of the Legend of the Five Suns, Tecpatl becomes temporal marker of the birth of the Centzonmimixcoa, according to Bernardino de Sahagún and Diego Durán they present the homology between this myth and ritual. When the other women looked at what was in it, it was a flint and iron were sandeel, meanwhile, Duran tells his priests sought a child cot and put into it a flint knife with which they sacrificed the one they called the son of Cihuacoatl. In the version where the Centzonmimixcoa are born from the Tecpatl, in the version that is temporary marker Tecpatl birth, the mother is Iztac Chalchiuhtlicue, and in rites the mother of Tecpatl is Cihuacoatl. In Aztec mythology, the tecpatl was sometimes drawn as a flint blade, sharpened with some notches on the edge. Tecpatl was associated with Northern cardinal point, the dark place of eternal stillness and rest of the dead. The ancient Anahuac, considered the Tecpatl as a symbol of Xiuhtecuhtli tletl and it also relates to Ehecatl, since in the codices its represented by high winds, meaning that the air cuts like razor, so it represented xopantla, the time of high winds. The image of the tecpatl was a symbol and therefore ruled agricultural events. Their patron gods were, Chalchiuhtotolin and Tezcatlipoca, in the trecena of Ce Tecpatl, the gods were Tonatiuh and Mictlantecuhtli

Nahua peoples
–
The Nahuas are a group of indigenous people of Mexico and El Salvador. Their language of Uto-Aztecan affiliation is called Nahuatl and consists of many dialects and variants. About 1,500,000 Nahua speak Nahuatl and another 1,000,000 speak only Spanish, less than 1,000 native speakers remain in El Salvador. Evidence suggests the Nahua peoples originated in Aridoamerica, in regions of the present day northwestern Mexico and they split off from the other Uto-Aztecan speaking peoples and migrated into central Mexico around 500 CE. They settled in and around the Basin of Mexico and spread out to become the dominant people in central Mexico, the name Nahua is derived from the Nahuatl word-root nāhua-, which generally means audible, intelligible, clear with different derivations including language. It was used in contrast with popoloca, to speak unintelligibly or speak a foreign language, another, related term is Nāhuatlācatl or Nāhuatlācah literally Nahuatl-speaking people. The Nahuas are also referred to as Aztecs. Using this term for the Nahuas has generally fallen out of favor in scholarship and they have also been called Mēxihcatl, Mēxihcah or in Spanish Mexicano Mexicans, after the Mexica, the Nahua tribe which founded and predominated in the Aztec empire. At the turn of the 16th century, Nahua populations occupied territories ranging across modern-day Mexico, El Salvador, Guatemala and these were gradually assimilated into mestizo society in most places. The last of the southern Nahua populations are the Pipil of El Salvador, Nahuatl was a lingua franca for trade and rule during the apogee of the Aztec empire. There are many Nahuatl place names in regions where Nahuas were not the most populous group, Nahua populations in Mexico are centered in the middle of the country, with most speakers in the states of Puebla, Veracruz, Hidalgo, Guerrero and San Luis Potosí. But smaller populations are spread throughout the country, following recent population movements within Mexico, within the last 50 years, Nahua populations have appeared in the United States, particularly in New York City, L. A. and Houston. Archaeological, historical and linguistic evidence suggest that the Nahuas originally came from the deserts of northern Mexico, before the Nahuas entered Mesoamerica, they were probably living for a while in northwestern Mexico alongside the Cora and Huichol peoples. The first group of Nahuas to split from the group were the Pochutec who went on to settle on the Pacific coast of Oaxaca possibly as early as 400 CE. From c.600 CE the Nahua quickly rose to power in central Mexico and expanded into areas earlier occupied by Oto-Manguean, Totonacan and Huastec peoples. Around 1000 CE the Toltec people, normally assumed to have been of Nahua ethnicity, from this period on the Nahua were the dominant ethnic group in the Valley of Mexico and far beyond, and migrations kept coming in from the north. After the fall of Toltecs a period of population movements followed. And in central Mexico different Nahua groups based in their different Altepetl city-states fought for political dominance

Azcapotzalco
–
Azcapotzalco is one of the 16 municipalities into which Mexicos Mexico City is divided. Azcapotzalco is in the part of Mexico City. The town began in the era and was the seat of the Tepanec dominion until the Aztec Triple Alliance overthrew it. After that it was a farming area becoming part of the Federal District of Mexico City in the mid-19th century. In the 20th century the area was engulfed by the urban sprawl of Mexico City, today it is 100% urbanized and is a center of industry. The municipality of Azcapotzalco is in the Valley of Mexico with its eastern half on the lakebed of the former Lake Texcoco, the historic center is on the former shoreline of this lake. The average altitude is 2240 meters above sea level and it has a semi moist temperate climate with an average temperature of 15C. As the municipality is 100% urbanized, there are no ecological reserves and it is divided into 2,723 city blocks. There are 54 parks which have no wild vegetation but rather planted species such as willow, cedar and these parks cover 100.51 hectares, which is 2. 9% of the entire municipality. The most important of these are the Parque Tezozómoc and Alameda Norte, Parque Tezozomoc was inaugurated in 1982 designed as a scaled replica of the Valley of Basin of Mexico in the pre-Hispanic era. The Alamedia Norte park is next to the Ferrería station and it has a pond which was used as an ice rink and playing field but was rehabilitated in the 2000s. Sports facilities cover about 67 hectares of the municipality with 70 fields and these include the Deportivo Renovacion Nacional, Deportivo Reynosa, Centro Deportivo Ferrocarrilero and the Unidad Deportiva Benito Juarez. Deportivo Reynosa used to host one of Mexico City’s temporary “artificial beaches” consisting of pools and a sand area, the municipality has cemeteries which are counted as green spaces, especially San Isidro because of its large size. There is little water with the exception of the Río de los Remedios which is primarily used for drainage of wastewater. The lowering of water tables in the valley has led to large cracks developing in areas of the municipality which has caused damage to infrastructure, the municipality is flat with inclines of between zero and five percent with no prominent elevations. Because of its flatness, flooding is a problem in heavy rain, especially in such as Santiago Ahuizotla, Nueva Santa María, San Pedro Xalpa. Sixty five percent of the municipality is occupied by about 500 industries which use toxic substances, there are hundreds of km of underground gas lines. Nine communities have been classified as high risk because they are surrounded by industries, there are 250 chemical producers mostly concentrated in Colonia Industrial Vallejo which make ethanol, cyanide compounds, phosphates, organic solvents and more

Municipalities of Mexico City
–
Mexico City is divided into sixteen mayoralties, which have regulatory powers and are not fully autonomous in their internal administration. As of 2000, the citizens within a mayoralty elect by plurality a head of government, as of 2016, mexico City recorded an official 2010 census tally of 8,851,080 inhabitants. The municipalities are subdivided into neighborhoods and in cases in the southernmost municipalities, also into towns. Mexico City as a whole is bordered directly by the municipalities, going clockwise

Mexico City
–
Mexico City, or City of Mexico, is the capital and most populous city of Mexico. As an alpha global city, Mexico City is one of the most important financial centers in the Americas and it is located in the Valley of Mexico, a large valley in the high plateaus at the center of Mexico, at an altitude of 2,240 metres. The city consists of sixteen municipalities, the 2009 estimated population for the city proper was approximately 8.84 million people, with a land area of 1,485 square kilometres. The Greater Mexico City has a domestic product of US$411 billion in 2011. The city was responsible for generating 15. 8% of Mexicos Gross Domestic Product, as a stand-alone country, in 2013, Mexico City would be the fifth-largest economy in Latin America—five times as large as Costa Ricas and about the same size as Perus. Mexico’s capital is both the oldest capital city in the Americas and one of two founded by Amerindians, the other being Quito. In 1524, the municipality of Mexico City was established, known as México Tenochtitlán, Mexico City served as the political, administrative and financial center of a major part of the Spanish colonial empire. After independence from Spain was achieved, the district was created in 1824. Ever since, the left-wing Party of the Democratic Revolution has controlled both of them, in recent years, the local government has passed a wave of liberal policies, such as abortion on request, a limited form of euthanasia, no-fault divorce, and same-sex marriage. On January 29,2016, it ceased to be called the Federal District and is now in transition to become the countrys 32nd federal entity, giving it a level of autonomy comparable to that of a state. Because of a clause in the Mexican Constitution, however, as the seat of the powers of the federation, it can never become a state, the city of Mexico-Tenochtitlan was founded by the Mexica people in 1325. According to legend, the Mexicas principal god, Huitzilopochtli indicated the site where they were to build their home by presenting an eagle perched on a cactus with a snake in its beak. Between 1325 and 1521, Tenochtitlan grew in size and strength, eventually dominating the other city-states around Lake Texcoco, when the Spaniards arrived, the Aztec Empire had reached much of Mesoamerica, touching both the Gulf of Mexico and the Pacific Ocean. After landing in Veracruz, Spanish explorer Hernán Cortés advanced upon Tenochtitlan with the aid of many of the native peoples. Cortés put Moctezuma under house arrest, hoping to rule through him, the Aztecs thought the Spaniards were permanently gone, and they elected a new king, Cuitláhuac, but he soon died, the next king was Cuauhtémoc. Cortés began a siege of Tenochtitlan in May 1521, for three months, the city suffered from the lack of food and water as well as the spread of smallpox brought by the Europeans. Cortés and his allies landed their forces in the south of the island, the Spaniards practically razed Tenochtitlan during the final siege of the conquest. Cortés first settled in Coyoacán, but decided to rebuild the Aztec site to erase all traces of the old order and he did not establish a territory under his own personal rule, but remained loyal to the Spanish crown

Mesoamerican chronology
–
Mesoamerican chronology divides the history of pre-Columbian Mesoamerica into several periods, the Paleo-Indian, the Archaic, the Preclassic or Formative, the Classic, and the Postclassic. However, this applies to other pre-Columbian Mesoamerican civilizations as well. 3500-2000 BCE During the Archaic Era agriculture was developed in the region, Late in this era, use of pottery and loom weaving became common, and class divisions began to appear. Many of the technologies of Mesoamerica in terms of stone-grinding, drilling. 1800 BCE–200 CE During the Preclassic Era, or Formative Period, large-scale ceremonial architecture, writing, cities, the Olmec civilization developed and flourished at such sites as La Venta and San Lorenzo Tenochtitlán. 200–1000 CE The Classic Era was dominated by numerous independent city-states in the Maya region and also featured the beginnings of political unity in central Mexico, regional differences between cultures grew more manifest. The city-state of Monte Albán dominated the Valley of Oaxaca until the late Classic, highly sophisticated arts such as stuccowork, architecture, sculptural reliefs, mural painting, pottery, and lapidary developed and spread during the Classic era. In the Maya region, numerous city states such as Tikal, Calakmul, Copán, Palenque, Uxmal, Cobá, each of these polities was generally independent, although they often formed alliances and sometimes became vassal states of each other. The main conflict during this period was between Tikal and Calakmul, who fought a series of wars over the course of more than half a millennium, each of these states declined during the Terminal Classic and were eventually abandoned. This is sometimes seen as a period of increased chaos and warfare, the Postclassic is often viewed as a period of cultural decline. However, it was a time of technological advancement in architecture, engineering, metallurgy came into use for jewelry and some tools, with new alloys and techniques being developed in a few centuries. The Postclassic was a period of rapid movement and population growth — especially in Central Mexico post-1200 —, for instance, in Yucatán, dual rulership apparently replaced the more theocratic governments of Classic times, whilst oligarchic councils operated in much of Central Mexico. Likewise, it appears that the wealthy pochteca and military orders became more powerful than was apparently the case in Classic times and this afforded some Mesoamericans a degree of social mobility. The Toltec for a time dominated central Mexico in the 11th–13th century, the northern Maya were for a time united under Mayapan, and Oaxaca was briefly united by Mixtec rulers in the 11th–12th centuries. The Aztec Empire arose in the early 15th century and appeared to be on a path to asserting dominance over the Valley of Mexico region not seen since Teotihuacan. Spain was the first European power to contact Mesoamerica, however, and its conquistadores, by the 15th century, the Mayan revival in Yucatán and southern Guatemala and the flourishing of Aztec imperialism evidently enabled a renaissance of fine arts and science. Examples include the Pueblan-Mexica style in pottery, codex illumination, and goldwork, the flourishing of Nahua poetry, arguably, the Post-Classic continued until the conquest of the last independent native state of Mesoamerica, Tayasal, in 1697. Mesoamerican civilization was a network of different cultures

Valley of Mexico
–
The Valley of Mexico is a highlands plateau in central Mexico roughly coterminous with the present-day Distrito Federal and the eastern half of the State of Mexico. Surrounded by mountains and volcanoes, the Valley of Mexico was a centre for several civilizations, including Teotihuacan, the Toltec. The ancient Aztec term Anahuac and the phrase Basin of Mexico are both used at times to refer to the Valley of Mexico, the Basin of Mexico became a well known site that epitomized the scene of early Classic Mesoamerican cultural development as well. The Valley of Mexico is located in the Trans-Mexican Volcanic Belt, the valley contains most of the Mexico City Metropolitan Area, as well as parts of the State of Mexico, Hidalgo, Tlaxcala and Puebla. The Valley of Mexico can be subdivided into four basins, but the largest and this section of the valley in particular is colloquially referred to as the Valley of Mexico. The valley has an altitude of 2,200 meters above sea level and is surrounded by mountains. It is a valley with no natural outlet for water to flow. Within this vulnerable watershed all the fishes were extinct by the end of the 20th century. Hydrologically, the valley has three features, the first feature is the lakebeds of five now-extinct lakes, which are located in the southernmost and largest of the four sub-basins. The other two features are piedmont, and the mountainsides that collect the precipitation that eventually flows to the lake area and these last two are found in all four of the sub-basins of the valley. Today, the Valley drains through a series of canals to the Tula River, and eventually the Pánuco River. Seismic activity is frequent here, and the valley is considered an earthquake prone zone, the valley has been inhabited for at least 12,000 years, attracting humans with its mild climate, abundant game and ability to support large-scale agriculture. Civilizations that have arisen in this include the Teotihuacan the Toltec Empire. When the Spaniards arrived in the Valley of Mexico, it had one of the highest population concentrations in the world with one million people. After the Conquest, the Spaniards rebuilt the largest and most dominant city here, Tenochtitlan, although violence and disease significantly lowered the population of the valley after the Conquest, by 1900 it was again over one million people. The 20th and 21st centuries have seen an explosion of population in the valley along with the growth of industry, since 1900, the population has doubled every fifteen years. Today, around 21 million people live in the Mexico City Metropolitan Area which extends throughout almost all of the valley into the states of Mexico, the growth of a major urban, industrial centre in an enclosed basin has created significant air and water quality issues for the valley. Wind patterns and thermal inversions trap contaminants in the valley, over-extraction of ground water has caused new flooding problems for the city as it sinks below the historic lake floor

Squatting
–
Squatting is the action of occupying an abandoned or unoccupied area of land or a building, usually residential—that the squatter does not own, rent or otherwise have lawful permission to use. Author Robert Neuwirth suggested in 2004 that there were one billion squatters globally and he forecasts there will be two billion by 2030 and three billion by 2050. Yet, according to Kesia Reeve, squatting is largely absent from policy and academic debate and is rarely conceptualised, as a problem, as a symptom, Squatting can be related to political movements, such as anarchist, autonomist, or socialist. It can be a means to conserve buildings or to provide housing, while these settlements may, in time, grow to become both legalised and indistinguishable from normal residential neighbourhoods, they start off as squats with minimal basic infrastructure. Thus, there is no sewage system, drinking water must be bought from vendors or carried from a nearby tap, besides being residences, some squats are used as social centres or host give-away shops, pirate radio stations or cafés. In Spanish-speaking countries, squatters receive several names, such as okupas in Spain, Chile or Argentina, Squatting by necessity is in itself a political issue, therefore also a statement or rather a response to the political system causing it. During the period of recession and increased housing foreclosures in the 2000s, squatting became far more prevalent in Western. In some cases, need-based and politically motivated squatting go hand in hand, conservational – i. e. preserving monuments because the authorities have let them decay Political – e. g. Property law and the state have traditionally favored the property owner, however, in many cases where squatters had de facto ownership, laws have been changed to legitimize their status. Anarchist Colin Ward comments, Squatting is the oldest mode of tenure in the world and this is as true of the Queen with her 176,000 acres as it is of the 54 percent of householders in Britain who are owner-occupiers. They are all the recipients of stolen land, for to regard our planet as a commodity offends every conceivable principle of natural rights. U. K. police official Sue Williams, for example, has stated that Squatting is linked to Anti-Social Behaviour and can cause a great deal of nuisance, in some cases there may also be criminal activities involved. The public attitude toward squatting varies, depending on legal aspects, socioeconomic conditions, in particular, while squatting of municipal buildings may be treated leniently, squatting of private property often leads to strong negative reaction on the part of the public and authorities. Adverse possession is a method of acquiring title to property through possession for a period under certain conditions. Countries where this principle exists include England and the United States, however, some non-common law jurisdictions have laws similar to adverse possession. For example, Louisiana has a doctrine called acquisitive prescription. There are large communities in Kenya, such as Kibera in Nairobi. An estimated 1,000 people live in the Grande Hotel Beira in Mozambique, the Zabbaleen settlement and the City of the Dead are both well-known squatter communities in Cairo

Lake Texcoco
–
Lake Texcoco was a natural lake within the Anáhuac or Valley of Mexico. Lake Texcoco is best known as where the Aztecs built the city of Tenochtitlan, after the Spanish conquest of the Aztec Empire, efforts to control flooding by the Spanish led to most of the lake being drained. The entire lake basin is now almost completely occupied by Mexico City, in the Pleistocene era, the lake occupied an even greater area. There were several paleo-lakes that would connect each other from time to time. At the north in the community of San Miguel Tocuilla there is a great paleontological field. The disarticulated remains of seven mammoths dated between 10,220 ±75 and 12,615 ±95 years were found, suggesting human presence, agriculture around the lake began about 7,000 years ago, with humans following the patterns of periodic inundations of the lake. On the northeast side of the lake, between 1700 and 1250 BC, several villages appear, by 1250 BC, the identifying signs of the Tlatilco culture, including more complex settlements and a stratified social structure, are seen around the lake. By roughly 800 BC, Cuicuilco had eclipsed the Tlatilco cultural centers and was the power in the Valley of Mexico during the next 200 years. The Xitle volcano destroyed Cuicuilco around AD30, a destruction that may have given rise to Teotihuacan, none of these predominated and they coexisted more or less in peace for several centuries. This time was described as a Golden age in Aztec chronicles, by the year 1300, however, the Tepanec from Azcapotzalco were beginning to dominate the area. If Tenochtitlan was the city of the Aztec Empire, and Mexico City the capital of Mexico, then Lake Texcoco is the Lake of the capitals. According to a story, the Mexica wandered in the deserts of modern Mexico for 100 years before they came to the thick forests of the place now called the Valley of Mexico. Tenochtitlan was founded on an islet in the part of the lake in the year 1325. Around it, the Aztecs created an artificial island using a system similar to the creation of chinampas. To overcome the problems of drinking water, the Aztecs built a system of dams to separate the salty waters of the lake from the water of the effluents. It also permitted them to control the level of the lake, the city also had an inner system of channels that helped to control the water. During Cortéss siege of Tenochtitlan in 1521, the dams were destroyed, the Valley of Mexico is a basin with an average elevation of 2,236 metres above mean sea level located in the southern highlands of Mexicos central altiplano. Lake Texcoco formerly extended over a portion of the southern half of the basin

Quivira
–
Quivira is a place named by explorer Francisco Vásquez de Coronado in 1541, for the mythical Seven Cities of Gold which he never found. The location of Quivira is believed by most authorities to be in central Kansas near present-day Lyons extending northeastern to Salina, the Quivirans were the forebears of the modern day Wichita Indians and Caddoan tribes, such as the Pawnee or Arikara. In 1539, the Spaniard, Francisco Vásquez de Coronado, led an expedition north from Mexico to search for wealth. Instead of wealth, he found farming peoples living in an array of communities and villages in what are today Arizona and these were the Apache, Navajo, Hopi, Zuni, and Rio Grande Pueblo Indians of today. Hearing of this, Coronado led his army of more than one thousand Spaniards, the Turk was his guide to Quivira. On his journey, Coronado traversed the panhandle of Texas and he found two groups of Indians, the Querechos and the Teyas. He was heading southeast when the Teyas told him that the Turk was taking him the wrong direction and it appears the Turk was luring the Spaniards away from New Mexico with tales of wealth in Quivira, hoping perhaps that they would get lost in the vastness of the Plains. Coronado sent most of his army back to New Mexico. With 30 mounted Spaniards, priests, Indian followers, the Turk, after a march of more than thirty days, he found a large river, probably the Arkansas, and soon met several Indians hunting buffalo. Coronado found Quivira “well settled. The land itself being very fat and black and being well watered by the rivulets and springs. I found prunes like those of Spain, and nuts and very good sweet grapes and mulberries. ”It was, he said, Coronado spent 25 days in Quivira and traveled about 65 miles from one end of the country to the other. He found nothing more than straw-thatched villages of up to two hundred houses each and fields of corn, beans, and squash and he found no gold, other than a single small piece which he reasoned had come into the natives hands from a member of his own expedition. Both men and women were nearly naked and they “were large people of good build” many of the men being over six feet tall. They seemed like giants compared to the Spaniards, Coronado was escorted to a farther boundary of Quivira, an area called Tabas, where the neighboring land of Harahey began. He summoned the Lord of Harahey who, with two hundred followers, came to meet the Spanish, the Harahey Indians were all naked—with bows and some sort of things on their heads, and their privy parts slightly covered. It was the sort of place. And of about the size as Quivira. Before leaving Quivira, Coronado ordered the Turk strangled, the Coronado expedition had failed in its quest for gold

Moctezuma I
–
Moctezuma I, also known as Motecuhzoma Ilhuicamina, Huehuemotecuhzoma or Montezuma I, was the second Aztec emperor and fifth king of Tenochtitlan. During his reign, the Aztec Empire was consolidated, major expansion was undertaken, Moctezuma was the son of emperor Huitzilihuitl and queen Miahuaxihuitl. He was a brother of Chimalpopoca, Tlacaelel I, and Huehue Zaca, and the father of Atotoztli II and their sons would be the next three tlatoque of Tenochtitlan. Moctezuma took power in 1440, after the death of his half-uncle Itzcoatl, as tlatoani, Moctezuma solidified the alliance with two neighboring states, Tlacopan and Texcoco. In this skillfully crafted Triple Alliance, 4/5ths of a conquered territory would be divided between Texcoco and the Aztecs, with the remaining 1/5 given to Tlacopan. In about 1458, Moctezuma led an expedition into Mixtec territory against the city-state of Coixtlahuaca, despite the support of contingents of Tlaxcala and Huexotzinco warriors, traditional enemies of the Aztecs, the Mixtecs were defeated. While most of the chieftains were allowed to retain their positions. He took many girls from Coixtlahuaca and had ten harems all to himself and he stole three of them from his dead brother Zaca. Similar campaigns were conducted against Cosamaloapan, Ahuilizapan, and Cuetlachtlan, list of Tenochtitlan rulers Moctezuma II Montezuma I

Nayarit
–
Nayarit, officially the Free and Sovereign State of Nayarit, is one of the 31 states which, with the Federal District, make up the 32 federal entities of Mexico. It is divided in 20 municipalities and its capital city is Tepic and it is located in Western Mexico. It is bordered by the states of Sinaloa to the northwest, Durango to the north, Zacatecas to the northeast, to the west, Nayarit has a significant share of coastline on the Pacific Ocean, including the islands of Marías and Marietas. The beaches of San Blas and the so-called Riviera Nayarit are popular with tourists, beside tourism, the economy of the state is based mainly on agriculture and fishing. Home to Uto-Aztecan indigenous peoples such as the Huichol and Cora, Spanish governance was made difficult by indigenous rebellions and by the inhospitable terrain of the Sierra del Nayar. The last independent Cora communities were subjugated in 1722, the states name recalls the Coras label for themselves, Náayerite, commemorating Nayar, a resistance leader. Encountered on the western coast by the Spanish invaders in 1500, hernándo was the first known European to enter into the area now known as Nayarit, which claimed for Spain as part of the colony of Nueva Galicia. As the Spaniards invaded the area, led by Nuño de Guzman, their brutality caused the inhabitants to revolt. After almost two centuries of resistance, the last independent Cora communities were incorporated into the administration by force in 1722. Then followed intense missionary efforts by Jesuit friars, in the colonial period, the port of San Blas was one of the most important trade ports on the American Pacific coast. Galleons transporting goods from Manila, the Philippines arrived here before the rise of the port of Acapulco, today, the town still boasts colonial architecture from the its heyday, such as the aduana, contaduria and the fortress that protected the port against pirates. In Nayarit, the struggle for independence from Spain was initiated by the priest José María Mercado, with the first independent constitution of 1824, Nayarit was a part of Jalisco state. During the second half of the 19th century, Nayarit was one of the most turbulent territories in Mexico, the population was in open revolt, demanding access to land. Nayarit was one of the last territories admitted as a state of the Mexican federation, Nayarit covers 27,815 square kilometers, making it one of the smaller states in Mexico. Nayarit is located between latitude lines 23°05 north and 20°36 south and longitude lines 103°43 east and 105°46 west and its terrain is broken up by the western ends of the Sierra Madre Occidental mountains. Its highest mountains are, San Juan, Sanguangüey, El Ceboruco, Nayarit has two volcanoes, Ceboruco and Sangangüey. In the northeast are broad, tropical plains watered by the Río Grande de Santiago, the main state rivers are the Río Grande de Santiago, San Pedro, Acaponeta, Ameca and Las Cañas. The Río Grande de Santiago is the largest river in Nayarit, the Santiago and its tributaries are of major importance for agricultural irrigation

Egret
–
An egret /ˈiːɡrət/ is a bird that is any of several herons, most of which are white or buff, and several of which develop fine plumes during the breeding season. Many egrets are members of the genera Egretta or Ardea which also contain other species named as herons rather than egrets, the distinction between a heron and an egret is rather vague, and depends more on appearance than biology. Several of the egrets have been reclassified from one genus to another in recent years, several Egretta species, including the eastern reef egret, the reddish egret, and the western reef egret have two distinct colours, one of which is entirely white. The little blue heron has all-white juvenile plumage, media related to Ardeidae at Wikimedia Commons Data related to Ardeidae at Wikispecies Great egret Ardea alba—USGS

Chicano Movement
–
Socially, the Chicano Movement addressed negative ethnic stereotypes of Mexicans in mass media and the American consciousness. While most people of Mexican descent still refused to call themselves Chicanos, Chicanos did this through the creation of works of literary and visual art that validated the Mexican American ethnicity and culture practices. The term Chicanos was originally used as a label for the sons. Some prefer to spell the word Chicano as Xicano and this new generation of Mexican Americans were singled out by people on both sides of the border in whose view these Mexican Americans were not American, yet they were not Mexican, either. In the 1960s Chicano was accepted as a symbol of self-determination, the Chicano Movement also addressed discrimination in public and private institutions. Early in the century, Mexican Americans formed organizations to protect themselves from discrimination. One of those organizations, the League of United Latin American Citizens, was formed in 1929, the Chicano Movement had been fermenting since the end of the U. S. –Mexican War in 1848, when the current U. S–Mexican border took form. Since that time, many Chicanos and Chicanas have campaigned against discrimination, racism, the Chicano Movement that culminated in the early 1970s took inspiration from heroes and heroines from their indigenous, Mexican and American past. The movement gained momentum after World War II when groups such as the American G. I, Forum, which was formed by returning Mexican American veterans, joined in the efforts by other civil rights organizations. After the Longoria incident, the AGIF quickly expanded throughout Texas and by the 1950s, there were several leaders throughout the Chicano Movement. In New Mexico there was Reies López Tijerina who worked on the land grant movement and he fought to regain control of what he considered ancestral lands. He became involved in civil rights causes within six years and also became a cosponsor of the Poor Peoples March on Washington in 1967. In Texas, war veteran Dr. Hector P. Garcia founded the American GI Forum and was appointed to the United States Commission on Civil Rights. In Denver, Rodolfo Corky Gonzáles helped define the meaning of being a Chicano through his poem Yo Soy Joaquin, in California, César Chávez and the farm workers turned to the struggle of urban youth, and created political awareness and participated in La Raza Unida Party. The most prominent civil rights organization in the Mexican-American community is the Mexican American Legal Defense and Educational Fund, founded in 1968. Although modeled after the NAACP Legal Defense and Educational Fund, MALDEF has also taken on many of the functions of organizations, including political advocacy. This led Chicana women to form the Comisión Femenil Mexicana Nacional, in 1975, it became involved in the case Madrigal v. Quilligan, obtaining a moratorium on the compulsory sterilization of women and adoption of bilingual consent forms. These steps were necessary because many Hispanic women who did not understand English well were being sterilized in the United States at the time, sVREPs mission is to empower Latinos and other minorities by increasing their participation in the American democratic process
