Politics and the Political System of the Ancient Maya

The Mayan civilization flourished in the rainforests of southern Mexico, Guatemala, and Belize, reaching its apex around A.D. 700–900 before falling into a swift and somewhat mysterious decline. The Maya were expert astronomers and traders: they were also literate with a complicated language and their own books. Like other civilizations, the Maya had rulers and a ruling class, and their political structure was complex. Their kings were powerful and claimed to be descended from the gods and the planets. The Mayan City-States The Mayan civilization was large, powerful, and culturally complex: it is often compared to the Incas of Peru and the Aztecs of Central Mexico. Unlike these other empires, however, the Maya never unified. Instead of a mighty empire ruled from one city by one set of rulers, the Maya instead had a series of city-states that only ruled the surrounding area, or some nearby vassal states if they were powerful enough. Tikal, one of the most powerful Mayan city-states, never ruled much farther than its immediate borders, although it did have vassal cities such as Dos Pilas and Copà ¡n. Each of these city-states had its own ruler. Development of Mayan Politics and Kingship The Mayan culture began around 1800 B.C. in the lowlands of the Yucatan and southern Mexico. For centuries, their culture slowly advanced, but as of yet, they had no concept of kings or royal families. It wasnt until the middle to late preclassic periods (300 B.C. or so) that evidence of kings began to appear at certain Mayan sites. The founding king of Tikals first royal dynasty, Yax Ehb Xook, lived sometime in the Preclassic period. By A.D. 300, kings were common, and the Maya began building stelae to honor them: large, stylized stone statues that describe the king, or Ahau, and his accomplishments. The Mayan Kings The Mayan kings claimed descent from the gods and planets, laying claim to a quasi-divine status, somewhere between humans and gods. As such, they lived between two worlds, and wielding â€Å"divine† power was part of their duties. The kings and royal family had important roles at public ceremonies, such as the ball games. They channeled their connection to the gods through sacrifices (of their own blood, of captives, etc.), dance, spiritual trances, and hallucinogenic enemas. Succession was usually patrilineal, but not always. Occasionally, queens ruled when no suitable male of the royal line was available or of age. All kings had numbers that placed them in order from the founder of the dynasty. Unfortunately, this number is not always recorded in the king’s glyphs on stone carvings, resulting on unclear histories of dynastic succession. Life of a Mayan King A Mayan king was groomed from birth to rule. A prince had to pass through many different initiations and rites. As a young man, he had his first bloodletting at the age of five or six. As a young man, he was expected to fight and lead battles and skirmishes against rival tribes. Capturing prisoners, particularly high-ranking ones, was important. When the prince finally became king, the elaborate ceremony included sitting on a jaguar pelt in an elaborate headdress of colorful feathers and seashells, holding a scepter. As king, he was supreme head of the military and was expected to fight and participate in any armed conflicts entered into by his city-state. He also had to participate in many religious rituals, as he was a conduit between humans and the gods. Kings were allowed to take multiple wives. Mayan Palaces Palaces are found at all of the major Mayan sites. These buildings were located in the heart of the city, near the pyramids and temples so important to Maya life. In some cases, the palaces were very large, multistoried structures, which may indicate that a complicated bureaucracy was in place to rule the kingdom. The palaces were homes to the king and the royal family. Many of the king’s tasks and duties were carried out not in the temples but in the palace itself. These events might have included feasts, celebrations, diplomatic occasions, and receiving tribute from vassal states. Classic-Era Mayan Political Structure By the time the Maya reached their Classic Era, they had a well-developed political system. Renowned archaeologist Joyce Marcus believes that by the Late Classic era, the Maya had a four-tiered political hierarchy. At the top were the king and his administration in major cities like Tikal, Palenque, or Calakmul. These kings would be immortalized on stelae, their great deeds recorded forever. Following the main city were a small group of vassal city-states, with lesser nobility or a relative of the Ahau in charge: these rulers did not merit stelae. After that were affiliated villages, large enough to have rudimentary religious buildings and ruled by minor nobility. The fourth tier consisted of hamlets, which were all or mostly residential and devoted to agriculture. Contact with Other City-States Although the Maya were never a unified empire like the Incas or Aztecs, the city-states nevertheless had much contact. This contact facilitated cultural exchange, making the Maya much more unified culturally than politically. Trade was common. The Maya traded in prestige items like obsidian, gold, feathers, and jade. They also traded in food items, particularly in later eras as the major cities grew too large to support their population. Warfare was also common: skirmishes to take slaves and victims for sacrifice were common, and all-out wars not unheard of. Tikal was defeated by rival Calakmul in 562, causing a century-long hiatus in its power before it reached its former glory once again. The powerful city of Teotihuacan, just north of present-day Mexico City, wielded great influence on the Mayan world and even replaced the ruling family of Tikal in favor of one more friendly to their city. Politics and the Decline of the Maya The Classic Era was the height of the Mayan civilization culturally, politically, and militarily. Between A.D. 700 and 900, however, the Maya civilization began a swift and irreversible decline. The reasons the Mayan society fell are still a mystery, but theories abound. As the Maya civilization grew, warfare between city-states grew as well: entire cities were attacked, defeated, and destroyed. The ruling class grew as well, placing a strain on the working classes, which may have resulted in civil strife. Food became a problem for some Maya cities as the population grew. When trade could no longer make up the differences, hungry citizens may have revolted or fled. The Mayan rulers might have avoided some of these calamities. Source McKillop, Heather.

10 Tungsten Facts - W or Atomic Number 74

Tungsten (atomic number 74, element symbol W) is a steel-gray to silver-white metal, familiar to many people as the metal used in incandescent light bulb filaments. Its element symbol W derives from an old name for the element, wolfram. Here are 10 interesting facts about tungsten: Tungsten Facts Tungsten is element number 74 with atomic number 74 and atomic weight 183.84. It is one of the transition metals and has a valence of 2, 3, 4, 5, or 6. In compounds, the most common oxidation state is VI. Two crystal forms are common. The body-centered cubic structure is more stable, but another metastable cubic structure may coexist with this form.The existence of tungsten was suspected in 1781, when Carl Wilhelm Scheele and T.O. Bergman made previously unknown tungstic acid from a material now called scheelite. In 1783, the Spanish brothers Juan  Josà © and Fausto DElhuyar isolated tungsten from wolframite ore and were credited with discovery of the element.The element name wolfram came from the name of the ore, wolframite, which derives from the German wolfs rahm, which means wolfs foam. It got this name because European tin smelters noticed the presence of wolframite in tin ore reduced the tin yield, appearing to eat tin like a wolf would devour sheep. What many people do not know is that the Delhuyar brothers actually proposed the name volfram for the element, as w was not used in the Spanish language at that point.  The element was known as wolfram in most European countries, but called tungsten (from Swedish tung sten meaning heavy stone, referencing the heaviness of scheelite ore) in English. In 2005, the International Union of Pure and Applied Chemistry dropped the name wolfram entirely, to make the periodic table the same in all countries. This is probably one of the most highly disputed name changes made on the periodic table.Tungsten has the highest melting point of the metals (6191.6  °F or 3422  °C), lowest vapor pressure, and the highest tensile strength. Its density is comparable to that of gold and uranium and 1.7 times higher than that of lead. While the pure element may be drawn, extruded, cut, forged, and spun, any impurities make tungsten brittle and difficult to work.The element is conductive and resists corrosion, although metal specimens will develop a characteristic yellowish cast upon exposure to air. A rainbow oxide layer is also possible. It is the 4th hardest element, after carbon, boron, and chromium. Tungsten is susceptible to slight attack by acids, but resists alkali and oxygen.Tungsten is one of the five refractory metals. The other metals are niobium, molybdenum, tantalum, and rhenium. These elements are clustered near each other on the periodic table. Refractory metals are those which exhibit extremely high resistance to heat and wear.Tungsten is considered to have low toxicity and plays a biological role in organisms. This makes it the heaviest element used in biochemical reactions. Certain bacteria use tungsten in an enzyme that reduces carboxylic acids to aldehydes. In animals, tungsten interferes with copper and molybdenum metabolism, so it is considered slightly toxic.Natural tungsten consists of five stable isotopes. These isotopes actually do undergo radioactive decay, but the half-lives are so long (four quintillion years) that they are stable for all practical purposes. At least 30 artificial unstable isotopes have also been recognized.Tungsten has many uses. It is used for filaments in electric lamps, in television and electron tubes, in metal evaporators, for electrical contacts, as an x-ray target, for heating elements, and in numerous high temperature applications. Tungsten is a common element in alloys, including tool steels. Its hardness and high density also make it an excellent metal for constructing penetrating projectiles. Tungsten metal is used for glass-to-metal seals. The elements compounds are used for fluorescent lighting, tanning, lubricants, and paints. Tungsten compounds find use as catalysts.Sources of tungsten include the minerals wolframite, scheelite, ferberite, and huebnertie. Its believed about 75% of the worlds supply of the element is found in China, although other ore deposits are known in the US, South Korea, Russia, Bolivia, and Portu gal. The element is obtained by reducing tungsten oxide from the ore with either hydrogen or carbon. Producing the pure element is difficult, due to its high melting point.

Criminological Theories On The Crime Scene And Measure...

Criminological Theories YourFirstName YourLastName University title Criminological Theories Name (Institutional Affiliation) According to Sutherland Edward one of the many founding fathers of modern day criminology, we as learners are able to learn that criminology is a body of knowledge that regards crime as social phenomenon. In details, criminology entails processes such as breaking laws, making laws, and the reactions taken towards breaking of laws. When it comes to the study of criminology as a whole, it’s crucial to note that the discipline have gone ahead to adopt various methods of study which comes from varying behavioral and social sciences. Similar to other scientists, criminologists assess the crime scene and measure characteristics of crimes, victims, and criminals using various methods. The advantages associated with trying to understand why people commit crimes is that, criminologists are able develop ways to not only control crimes but also rehabilitate the criminals (Larry, 2014). To be precise, there are many theories used in criminology in order to unde rstand why people commit crimes. For instance among the key theories that we have include- Strain theory, Social disorganization theory, Rational choice theory, and finally Social learning theory. Generally by looking at Strain theory, we are able to understand that this theory which was coined in by an American sociologist, Merton Robert, states that culturesShow MoreRelatedExplain the Strengths and Weaknesses of One or More Criminological Theories for Explaining Crime in Contemporary Britain2651 Words   |  11 Pagesand weaknesses of one or more criminological theories for explaining crime in contemporary Britain Word count:1,200 Outline plan * Explain in brief the purpose of this essay. * Define the biological theory. * Evaluate Lombroso’s theory and link it to contemporary Britain.

Domain System Server Essays - Domain Name System, Name Server

Domain System Server Domain System Network software generally needs a 32-bit Internet address in order to open a connection or send a datagram. However users prefer to deal with computer names rather than numbers. Thus there is a database that allows the software to look up a name and find the corresponding number. When the Internet was small, this was easy. Each system would have a file that listed all of the other systems, giving both their name and number. There are now too many computers for this approach to be practical. Thus these files have been replaced by a set of name servers that keep track of host names and the corresponding Internet addresses. (In fact these servers are somewhat more general than that. This is just one kind of information stored in the domain system.) Note that a set of interlocking servers are used, rather than a single central one. There are now so many different institutions connected to the Internet that it would be impractical for them to notify a central authority whenever they installed or moved a computer. Thus naming authority is delegated to individual institutions. The name servers form a tree, corresponding to institutional structure. The names themselves follow a similar structure. A typical example is the name BORAX.LCS.MIT.EDU. This is a computer at the Laboratory for Computer Science (LCS) at MIT. In order to find its Internet address, you might potentially have to consult 4 different servers. First, you would ask a central server (called the root) where the EDU server is. EDU is a server that keeps track of educational institutions. The root server would give you the names and Internet addresses of several servers for EDU. (There are several servers at each level, to allow for the possibly that one might be down.) You would then ask EDU where the server for MIT is. Again, it would give you names and Internet addresses of several servers for MIT. Generally, not all of those servers would be at MIT, to allow for the possibility of a general power failure at MIT. Then you would ask MIT where the server for LCS is, and finally you would ask one of the LCS servers about BORAX. The final result would be the Internet address for BORAX.LCS.MIT.EDU. Each of these levels is referred to as a "domain". The entire name, BORAX.LCS.MIT.EDU, is called a "domain name". (So are the names of the higher-level domains, such as LCS.MIT.EDU, MIT.EDU, and EDU.) Fortunately, you don't really have to go through all of this most of the time. First of all, the root name servers also happen to be the name servers for the top-level domains such as EDU. Thus a single query to a root server will get you to MIT. Second, software generally remembers answers that it got before. So once we look up a name at LCS.MIT.EDU, our software remembers where to find servers for LCS.MIT.EDU, MIT.EDU, and EDU. It also remembers the translation of BORAX.LCS.MIT.EDU. Each of these pieces of information has a "time to live" associated with it. Typically this is a few days. After that, the information expires and has to be looked up again. This allows institutions to change things. The domain system is not limited to finding out Internet addresses. Each domain name is a node in a database. The node can have records that define a number of different properties. Examples are Internet address, computer type, and a list of services provided by a computer. A program can ask for a specific piece of information, or all information about a given name. It is possible for a node in the database to be marked as an "alias" (or nickname) for another node. It is also possible to use the domain system to store information about users, mailing lists, or other objects. There is an Internet standard defining the operation of these databases, as well as the protocols used to make queries of them. Every network utility has to be able to make such queries, since this is now the official way to evaluate host names. Generally utilities will talk to a server on their own system. This server will take care of contacting the other servers for them. This keeps down the amount of code that has to be in each application program. The domain system is particularly important for handling computer mail. There are entry types to define what computer handles mail for a given name, to specify where an individual is to receive mail, and to

U.S Constitution essays

U.S Constitution essays In 1787, a few years after America broke away from England, the constitution we use today was made. Before that, starting in 1777, the states operated under a government they called the Articles of Confederation. This government basically said that each state should have its own independence, and operate within their own government. After about 6 years, this government didnt work very well, because of civil unrest, bad trade, and inflation.
