The earliest human civilizations developed independently of each other and a cradle of civilization is a location and a culture from which one of them emerged. A civilization is any complex society characterized by the development of a state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems and graphic arts).
Scholars generally acknowledge six cradles of civilization: Mesopotamia, Ancient Egypt, Ancient India and Ancient China are believed to be the earliest in Afro-Eurasia,Cradles of Civilization-China: Ancient Culture, Modern Land, Robert E. Murowchick, gen. ed. Norman: University of Oklahoma Press, 1994. 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.
Rise of civilization
The earliest signs of a process leading to sedentary culture can be seen in the Levant as early as 12,000 BC, when the Natufian culture became sedentary; it evolved into an agricultural society by 10,000 BC. The importance of water to safeguard an abundant and stable food supply, due to favourable conditions for hunting, fishing and gathering resources including cereals, provided an initial wide spectrum economy that triggered the creation of permanent villages.La protohistoire de l'Europe, Jan Lichardus et al., Presses Universitaires de France, Paris. , 1987, chapter II.2.
The earliest proto-urban settlements with several thousand inhabitants emerged in the Neolithic which began in Western Asia in 10,000 BC. The first cities to house several tens of thousands were Uruk, Ur, Kish and Eridu in Mesopotamia, followed by Susa in Elam and Memphis in Egypt, all by the 31st century BC (see Historical urban community sizes).
Historic times are marked apart from prehistoric times when "records of the past begin to be kept for the benefit of future generations"—in written or oral form. If the rise of civilization is taken to coincide with the development of writing out of proto-writing, then the Near Eastern Chalcolithic (the transitional period between the Neolithic and the Bronze Age during the 4th millennium BC) and the development of proto-writing in Harappa in the Indus Valley of South Asia around 3,300 BC are the earliest instances, followed by Chinese proto-writing evolving into the oracle bone script, and again by the emergence of Mesoamerican writing systems from about 900 BC.
In the absence of written documents, most aspects of the rise of early civilizations are contained in archaeological assessments that document the development of formal institutions and the material culture. A "civilized" way of life is ultimately linked to conditions coming almost exclusively from agriculture. Gordon Childe defined the development of civilization as the result of two successive revolutions: the Neolithic Revolution of Western Asia, triggering the development of settled communities, and the urban revolution which also first emerged in Western Asia, which enhanced tendencies towards dense settlements, specialized occupational groups, social classes, exploitation of surpluses, monumental public buildings and writing. Few of those conditions, however, are unchallenged by the records: dense cities were not attested in Egypt's Old Kingdom (unlike Mesopotamia) and cities had a dispersed population in the Maya area; the Incas lacked writing although they could keep records with Quipus which might also have had literary uses; and often monumental architecture preceded any indication of village settlement. For instance, in present-day Louisiana, researchers have determined that cultures that were primarily nomadic organized over generations to build earthwork mounds at seasonal settlements as early as 3400 BC. Rather than a succession of events and preconditions, the rise of civilization could equally be hypothesized as an accelerated process that started with incipient agriculture and culminated in the Oriental Bronze Age.Britannica 15th edition, 26:62–63.
Single or multiple cradles Scholars once thought that civilization began in the Fertile Crescent and spread out from there by influence. Scholars now believe that civilizations arose independently at several locations in both hemispheres. They have observed that sociocultural developments occurred along different timeframes. "Sedentary" and "nomadic" communities continued to interact considerably; they were not strictly divided among widely different cultural groups. The concept of a cradle of civilization focuses on the peoples who built cities, created writing systems, experimented with pottery and using metals techniques, domesticate animals, and developed complex social structures involving class systems.
Today, scholarship generally identifies six areas where civilization emerged independently: the Fertile Crescent, including Mesopotamia and the Levant; the Nile Valley in Northeast Africa; the Indo-Gangetic Plain; the North China Plain; the Andean Coast; and the Mesoamerican Gulf Coast.
Cradles of civilization Fertile Crescent
The Fertile Crescent comprises a crescent-shaped region of elevated terrain in West Asia, encompassing regions of modern-day Egypt, Palestine, Israel, Lebanon, Syria, Jordan, Turkey, and Iraq, extending to the Zagros Mountains in Iran. It stands as one of the earliest regions globally where agricultural practices emerged, marking the advent of sedentary farming communities.
By 10,200 BC, fully developed Neolithic cultures, characterized by the Pre-Pottery Neolithic A (PPNA) and Pre-Pottery Neolithic B (7600 to 6000 BC) phases, emerged within the Fertile Crescent. These cultures diffused eastward into South Asia and westward into Europe and North Africa.Bellwood, Peter. First Farmers: The Origins of Agricultural Societies. 2004. Wiley-Blackwell. Among the notable PPNA settlements is Jericho, located in the Jordan Valley, believed to be the world's earliest established city, with initial settlement dating back to around 9600 BC and fortification occurring around 6800 BC.
Current theories and findings identify the Fertile Crescent as the first and oldest cradle of civilization. Examples of sites in this area are the early Neolithic site of Göbekli Tepe (9500–8000 BC) and Çatalhöyük (7500–5700 BC).
Mesopotamia
In Mesopotamia (a region encompassing modern Iraq and bordering regions of Southeast Turkey, Northeast Syria and Northwest Iran), the convergence of the Tigris and Euphrates rivers produced rich fertile soil and a supply of water for irrigation. Neolithic cultures emerged in the region from 8000 BC onwards. The civilizations that emerged around these rivers are the earliest known non-nomadic agrarian societies. It is because of this that the Fertile Crescent region, and Mesopotamia in particular, are often referred to as the cradle of civilization. The period known as the Ubaid period (c. 6500 to 3800 BC) is the earliest known period on the alluvial plain, although it is likely earlier periods exist obscured under the alluvium.Adams, Robert M.C.C. and Wright, Henry T. 1989. 'Concluding Remarks' in Henrickson, Elizabeth and Thuesen, Ingolf (eds.) Upon This Foundation – The 'Ubaid Reconsidered. Copenhagen: Museum Tusculanum Press. pp. 451–456.Carter, Robert A. and Philip, Graham Beyond the Ubaid: Transformation and Integration in the Late Prehistoric Societies of the Middle East (Studies in Ancient Oriental Civilization, Number 63) The Oriental Institute of the University of Chicago (2010) p. 2, at http://oi.uchicago.edu/research/pubs/catalog/saoc/saoc63.html ; "Radiometric data suggest that the whole Southern Mesopotamian Ubaid period, including Ubaid 0 and 5, is of immense duration, spanning nearly three millennia from about 6500 to 3800 B.C.". It was during the Ubaid period that the movement toward urbanization began. Agriculture and animal husbandry were widely practiced in sedentary communities, particularly in Northern Mesopotamia (later Assyria), and intensive irrigated hydraulic agriculture began to be practiced in the south.
Around 6000 BC, Neolithic settlements began to appear all over Egypt. Studies based on morphological, genetic, and archaeological data have attributed these settlements to migrants from the Fertile Crescent in the Near East arriving in Egypt and North Africa during the Egyptian and North African Neolithic Revolution and bringing agriculture to the region. Tell el-'Oueili is the oldest Sumerian site settled during this period, around 5400 BC, and the city of Ur also first dates to the end of this period.Leick, Gwendolyn (2002), "Mesopotamia: The Invention of the City" (Penguin). In the south, the Ubaid period lasted from around 6500 to 3800 BC.Carter, Robert A. and Philip, Graham. 2010. 'Deconstructing the Ubaid' in Carter, Robert A. and Philip, Graham (eds.) Beyond the Ubaid: Transformation and Integration in the Late Prehistoric Societies of the Middle East. Chicago: The Oriental Institute of the University of Chicago. p. 2.
Sumerian civilization coalesced in the subsequent Uruk period (4000 to 3100 BC).Crawford, Harriet E. W. Sumer and the Sumerians. Cambridge University Press. 2nd ed. 2004. Named after the Sumerian city of Uruk, this period saw the emergence of urban life in Mesopotamia and, during its later phase, the gradual emergence of the cuneiform script. Proto-writing in the region dates to around 3800 BC, with the earliest texts dating to 3300 BC; early cuneiform writing emerged in 3000 BC. It was also during this period that pottery painting declined as copper started to become popular, along with cylinder seals.An Encyclopedia of World History. Langer, William L. ed. Houghton Mifflin Company. Boston, MA. 1972. Sumerian cities during the Uruk period were probably theocratic and were most likely headed by a priest-king (ensi), assisted by a council of elders, including both men and women.Jacobsen, Thorkild (Ed.) (1939), "The Sumerian King List" (Oriental Institute of the University of Chicago; Assyriological Studies, No. 11, 1939). It is quite possible that the later Sumerian pantheon was modeled upon this political structure.
The Jemdet Nasr period, which is generally dated from 3100 to 2900 BC and succeeds the Uruk period, is known as one of the formative stages in the development of the cuneiform script. The oldest clay tablets come from Uruk and date to the late fourth millennium BC, slightly earlier than the Jemdet Nasr Period. By the time of the Jemdet Nasr Period, the script had already undergone a number of significant changes. It originally consisted of pictographs, but by the time of the Jemdet Nasr Period it was already adopting simpler and more abstract designs. It is also during this period that the script acquired its iconic wedge-shaped appearance..Martin (1988), pp. 20–23.
