Energy consumption in three types of civilization as defined by Sagan's extended Kardashev scale The Kardashev scale (Russian: шкала Кардашёва, romanized: shkala Kardashyeva) is a method of measuring a civilization's level of technological advancement based on the amount of energy it is capable of harnessing and using. The measure was proposed by Soviet astronomer Nikolai Kardashev in 1964, and was named after him.
Kardashev first outlined his scale in a paper presented at the 1964 conference that communicated findings on BS-29-76, Byurakan Conference in the Armenian SSR, which he initiated, a scientific meeting that reviewed the Soviet radio astronomy space listening program. The paper was titled "Передача информации внеземными цивилизациями" ("Transmission of Information by Extraterrestrial Civilizations"). Starting from a functional definition of civilization, based on the immutability of physical laws and using human civilization as a model for extrapolation, Kardashev's initial model was developed. He proposed a classification of civilizations into three types, based on the axiom of exponential growth:
A Type II civilization (stellar) can directly consume a star's energy, most likely through the use of a Dyson sphere.
A Type III civilization (galactic) is able to capture all the energy emitted by its galaxy, and every object within it, such as every star, black hole, etc.
Superpower describes a sovereign state or supranational union that holds a dominant position characterized by the ability to exert influence and project power on a global scale. This is done through the combined means of economic, military, technological, political, and cultural strength as well as diplomatic and soft power influence. Traditionally, superpowers are preeminent among the great powers. While a great power state is capable of exerting its influence globally, superpowers are states so influential that no significant action can be taken by the global community without first considering the positions of the superpowers on the issue.
Scholars generally acknowledge six cradles of civilization: Mesopotamia, Ancient Egypt, Ancient India and Ancient China are believed to be the earliest in Afro-Eurasia, while the Caral–Supe civilization of coastal Peru and the Olmec civilization of Mexico are believed to be the earliest in the Americas. All of the cradles of civilization depended upon agriculture for sustenance (except possibly Caral–Supe which may have depended initially on marine resources). All depended upon farmers producing an agricultural surplus to support the centralized government, political leaders, religious leaders, and public works of the urban centers of the early civilizations.

The planetary phase of civilization is a term created by the Global Scenario Group (GSG) to describe the contemporary era in which increasing global interdependence and risks are binding the world into a unitary socio-ecological system. Characteristics of this phase include economic globalization, biospheric destabilization, mass migration, new global institutions, the Internet, new forms of transboundary conflict, and shifts in culture and consciousness.

Leaders of the G20 countries and others present at the 2008 G20 Washington summit. Most members of the G20 are middle powers, while some are great powers.A middle power is a state that exerts influence and plays a significant role in international relations but is not a superpower or a great power. These countries often possess certain capabilities, such as strong economies, advanced technologies, and diplomatic influence, that allow them to have a voice in global affairs. Middle powers are typically seen as bridge-builders between larger powers, using their diplomatic skills to mediate conflicts and promote cooperation on international issues.
Middle powers play a crucial role in the international system by promoting multilateralism, cooperation, and peaceful resolution of conflicts. They are able to leverage their resources and diplomatic skills to advance their national interests while also contributing to global stability and prosperity. As such, middle powers are an important and often overlooked factor in the complex web of international relations. (Full article...)
A great power is a sovereign state that is recognized as having the ability and expertise to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions.
While some nations are widely considered to be great powers, there is considerable debate on the exact criteria for great power status. Historically, great powers have been formally recognized as members of organizations such as the Congress of Vienna of 1814–1815 or the United Nations Security Council, of which the permanent members are China, France, Russia, the United Kingdom, and the United States. The United Nations Security Council, NATO Quint, the G7, BRICS, and the Contact Group have all been described as great power concerts. (Full article...)
A planetary or a Type I civilization is a civilization that would be global, likely having a tolerant worldwide society that functions through science and reason, and is capable of consuming all of the incoming energy from its neighboring star, or about 1017 watts for Earth. A planetary civilization or global civilization is a civilization of Type I on the Kardashev scale. This type of civilization is likely to be reliant on renewable energy sources such as stellar power, as well as powerful non-renewable sources such as nuclear fusion. A Type I civilization's energy consumption level is roughly equivalent to the solar insolation on Earth (between 1016 and 1017watts) – around 3 orders of magnitude higher than that of contemporary humanity (around 2×1013 as of 2020).

Location of foreign lands for the Mesopotamians, including Elam, Magan, Dilmun, Marhashi and Meluhha. Magan (also Majan) was an ancient region in what is now modern day Oman and United Arab Emirates. It was referred to in Sumeriancuneiform texts of around 2300 BCE and existed until 550 BCE as a source of copper and diorite for Mesopotamia. As discussed by The Archeology Fund founded by Juris Zarins, "The Sumerian cities of southern Mesopotamia were closely linked to the Persian Gulf. Archaeologists and historians have linked sites in Saudi Arabia, Bahrain, and Qatar to the Sumerian geographical term of Dilmun. Oman, was most likely the Sumerian Magan". (Full article...)
The civilizations of Classical Greece (Hellenic) and Roman Empire (Latin) as well as Ancient Israel (Hebraism) and early Christendom are considered seminal periods in Western history. From Ancient Greece sprang belief in democracy, and the pursuit of intellectual inquiry into such subjects as truth and beauty; from Rome came lessons in government administration, martial organization, engineering and law; and from Ancient Christianity with its ideals of the brotherhood of humanity. Strong cultural contributions also emerged from the pagan Germanic, Celtic, Finnic and Nordic peoples of pre-Christian Europe. Following the 5th-century "Fall of Rome", Europe entered the Middle Ages, during which period the Catholic Church filled the power vacuum left in the West by the fallen Roman Empire, while the Eastern Roman Empire (Byzantine Empire) endured for centuries.

Economy is conventionally defined as a function for production and distribution of goods and services by multiple agents within a society and/or geographical place An economy is hierarchical, made up of individuals that aggregate to make larger organizations such as governments and gives value to goods and services. The Maya economy had no universal form of trade exchange other than resources and services that could be provided among groups such as cacao beans and coppheological evidence to study the trade of perishable goods, it is noteworthy to explore the trade networks of artifacts and other luxury items that were likely transported together.
While subsistence agriculture played a central role in daily life, the Maya had a mechanism for economic exchange between settlements, which was capable of supporting specialists and a system of merchants through trade routes. Maya specialist Joanne Pillsbury states that "access to imported goods is perhaps the most recoverable aspect of prestige and leadership in ancient states." The power of Maya rulers not only depended on their ability to control resources, but also in managing the production and distribution of status goods as well as (non-local) commodities like salt. Furthermore, Maya laborers were subject to a labor tax to build palaces, temples and public works. A ruler successful in war was able to control more laborers and exact tribute on defeated enemies, further increasing their economic might. (Full article...)

Su Nuraxi of Barumini, included in the UNESCO list of World Heritage Sites since 1997 The Nuragic civilization, also known as the Nuragic culture, formed in the Mediterranean island of Sardinia, Italy in the Bronze Age. According to the traditional theory put forward by Giovanni Lilliu in 1966, it developed after multiple migrations from the West of people related to the Beaker culture who conquered and disrupted the local Copper Age cultures; other scholars instead hypothesize an autochthonous origin. It lasted from the 18th century BC (Middle Bronze Age), up to the Iron Age or until the Roman colonization in 238 BC. Others date the culture as lasting at least until the 2nd century AD, and in some areas, namely the Barbagia, to the 6th century AD — or possibly even to the 11th century AD, although it must be remarked that the construction of new nuraghi had already stopped by the 12th-11th century BC, during the Final Bronze Age.
The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt entered an era of slow decline. Over the course of its history, it was invaded or conquered by a number of foreign civilizations, including the Hyksos, the Kushites, the Assyrians, the Persians, and the Greeks and then the Romans. The end of ancient Egypt is variously defined as occurring with the end of the Late Period during the Wars of Alexander the Great in 332 BC or with the end of the Greek-ruled Ptolemaic Kingdom during the Roman conquest of Egypt in 30 BC. In AD 642, the Arab conquest of Egypt brought an end to the region's millennium-long Greco-Roman period. (Full article...)
The history of Maya civilization is divided into three principal periods: the Preclassic, Classic and Postclassic periods; these were preceded by the Archaic Period, which saw the first settled villages and early developments in agriculture. Modern scholars regard these periods as arbitrary divisions of chronology of the Maya civilization, rather than indicative of cultural evolution or decadence. Definitions of the start and end dates of period spans can vary by as much as a century, depending on the author. The Preclassic lasted from approximately 3000 BC to approximately 250 AD; this was followed by the Classic, from 250 AD to roughly 950 AD, then by the Postclassic, from 950 AD to the middle of the 16th century. Each period is further subdivided: (Full article...)

An ancient mound at the city of Kish, Mesopotamia, Babel Governorate, Iraq The Kish civilization was a civilization that was proposed in earlier theories among Ancient Near East scholars, which encompassed the sites of Ebla and Mari in the Levant, Nagar in the north, and the proto-Akkadian sites of Abu Salabikh and Kish in central Mesopotamia into the early East Semitic era in Mesopotamia and the Levant. The term itself was coined by Ignace Gelb. The epoch that this supposed civilization existed started from the early 4th millennium BC and ended with the rise of the Akkadian empire. The theory has been discarded by more recent scholarship. (Full article...)

The Aztec Empire in 1519 within Mesoamerica The Aztecs (/ˈæztɛks/AZ-teks) were a Mesoamerican civilization that flourished in central Mexico from 1300 to 1521. The Aztec people included different ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language. Aztec culture was organized into city-states (altepetl), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan (the capital city of the Mexica or Tenochca), Tetzcoco, and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahua polities or peoples of central Mexico in the prehispanic era, as well as the Spanish colonial era (1521–1821).
Most ethnic groups of central Mexico in the post-classic period shared essential cultural traits of Mesoamerica. The culture of central Mexico includes maize cultivation, the social division between nobility (pipiltin) and commoners (macehualtin), a pantheon, and the calendric system. Particular to the Mexica of Tenochtitlan was the patron god Huitzilopochtli, twin pyramids, and the ceramic styles known as Aztec I to IV. The Mexica were late-comers to the Valley of Mexico, and founded the city-state of Tenochtitlan on unpromising islets in Lake Texcoco, later becoming the dominant power of the Aztec Triple Alliance or Aztec Empire which conquered other city-states throughout Mesoamerica. It originated in 1427 as an alliance between the city-states Tenochtitlan, Texcoco, and Tlacopan to defeat the Tepanec state of Azcapotzalco, which had previously dominated the Basin of Mexico. Soon Texcoco and Tlacopan were relegated to junior partnership in the alliance, with Tenochtitlan the dominant power. The empire extended its reach by a combination of trade and military conquest. It was never a true territorial empire controlling territory by large military garrisons in conquered provinces but rather dominated its client city-states primarily by installing friendly rulers in conquered territories, constructing marriage alliances between the ruling dynasties, and extending an imperial ideology to its client city-states. Client city-states paid taxes, not tribute to the Aztec emperor, the Huey Tlatoani, in an economic strategy limiting communication and trade between outlying polities, making them dependent on the imperial center for the acquisition of luxury goods. The political clout of the empire reached far south into Mesoamerica conquering polities as far south as Chiapas and Guatemala and spanning Mesoamerica from the Pacific to the Atlantic oceans.

The Inca Empire and its road system encompassed most of the Andean civilization. The Andean civilizations were South American complex societies of many indigenous people. They stretched down the spine of the Andes for 4,000 km (2,500 miles) from southern Colombia, to Ecuador and Peru, including the deserts of coastal Peru, to north Chile and northwest Argentina. Archaeologists believe that Andean civilizations first developed on the narrow coastal plain of the Pacific Ocean. The Caral or Norte Chico civilization of coastal Peru is the oldest known civilization in the Americas, dating back to 3500 BCE. Andean civilizations are one of at least five civilizations in the world deemed by scholars to be "pristine." The concept of a "pristine" civilization refers to a civilization that has developed independently of external influences and is not a derivative of other civilizations.
Despite the severe environmental challenges of high mountains and hyper-arid desert, the Andean civilizations domesticated a wide variety of crops, some of which, such as potatoes, peppers, peanuts, manioc, chocolate, and coca, became of worldwide importance. The Andean civilizations were noteworthy for monumental architecture, an extensive road system, textile weaving, and many unique characteristics of the societies they created. (Full article...)
Extent of Etruscan civilization and the twelve Etruscan League cities
The Etruscans (/ɪˈtrʌskən/ih-TRUS-kən) created a civilization in Etruria in ancient Italy, with a common language and culture, and formed a federation of city-states. After adjacent lands had been conquered, its territory covered, at its greatest extent, roughly what is now Tuscany, western Umbria and northern Lazio, as well as what are now the Po Valley, Emilia-Romagna, south-eastern Lombardy, southern Veneto and western Campania.
A large body of literature has flourished on the origins of the Etruscans, but the consensus among modern scholars is that the Etruscans were an indigenous population. The earliest evidence of a culture that is identifiably Etruscan dates from about 900 BC. This is the period of the Iron AgeVillanovan culture, considered to be the earliest phase of Etruscan civilization, which itself developed from the previous late Bronze Age Proto-Villanovan culture in the same region, part of the central European Urnfield culture system.

Women in Carnival of Huejotzingo Women in Aztec civilization shared some equal opportunities. Aztec civilization saw the rise of a military culture that was closed off to women and made their role more prescribed to domestic and reproductive labor and less equal. The status of Aztec women in society was further altered in the 16th century, when Spanish conquest forced European norms onto the indigenous culture. However, many pre-Columbian norms survived and their legacy still remains. (Full article...)

The history of China spans several millennia across a wide geographical area. Each region now considered part of the Chinese world has experienced periods of unity, fracture, prosperity, and strife. Chinese civilization was traditionally thought to have first emerged in the Yellow River or Huang He valley, which along with the Yangtze basin constitutes the geographic core of the Chinese cultural sphere. However, current views have considered the origin to be a simultaneous duality of both the Yellow River and the Yangtze. China maintains a rich diversity of ethnic and linguistic people groups. The traditional lens for viewing Chinese history is the dynastic cycle: imperial dynasties rise and fall, and are ascribed certain achievements. This lens also tends to assume Chinese civilization can be traced as an unbroken thread many thousands of years into the past, making it one of the cradles of civilization. At various times, states representative of a dominant Chinese culture have directly controlled areas stretching as far west as the Tian Shan, the Tarim Basin, and the Himalayas, as far north as the Sayan Mountains, and as far south as the delta of the Red River.
Maritime trade goods of the Maya The extensive trade networks of the Ancient Maya contributed largely to the success of their civilization spanning three millennia. Maya royal control and the wide distribution of foreign and domestic commodities for both population sustenance and social affluence are hallmarks of the Maya visible throughout much of the iconography found in the archaeological record. In particular, moderately long-distance trade of foreign commodities from the Caribbean and Gulf Coasts provided the larger inland Maya cities with the resources they needed to sustain settled population levels in the several thousands. Though the ruling class essentially controlled the trade economy, a middle merchant class supervised import and export from cities and trade ports. Not much is known of the Maya merchant class; however, merchants of royal lineage are sometimes represented in the iconography. Notably, a canoe paddle often accompanies the royal merchant depictions, signifying their association with marine resources.
Water lilies are also a recognizable feature of Maya iconography, appearing on ceramics and murals in landlocked cities like Palenque where the lilies cannot grow, further indicating the important political symbolism of water connections. The dugout style canoes of the Maya and other small watercraft are also represented in various codices, sometimes ferrying royal figures or deities. The rich tradition of maritime trade has continued into the modern era, exemplified by the resource exploitation of the coastal lagoons and cay locations along the Caribbean coast of Mexico, Belize, Guatemala, and Honduras. Eventually, the intensification of maritime trade reliance aided in the collapse of interior Maya power regimes, shifting political influence to coastal polities such as Uxmal and Chichen Itza in the Terminal Classic. A seaborne trade economy would continue to dominate the Maya civilization until the period of European contact. (Full article...)
