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. 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. In the south, the Ubaid period lasted from around 6500 to 3800 BC. Sumerian civilization coalesced in the subsequent Uruk period (4000 to 3100 BC). 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. 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. 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. Uruk trade networks started to expand to other parts of Mesopotamia and as far as North Caucasus, and strong signs of governmental organization and social stratification began to emerge, leading to the Early Dynastic Period (c. 2900 BC). After the Early Dynastic period began, there was a shift in control of the city-states from the temple establishment headed by council of elders led by a priestly "En" (a male figure when it was a temple for a goddess, or a female figure when headed by a male god) towards a more secular Lugal (Lu = man, Gal = great). The Lugals included such legendary patriarchal figures as Enmerkar, Lugalbanda and Gilgamesh, who supposedly reigned shortly before the historic record opens around 2700 BC, when syllabic writing started to develop from the early pictograms. The center of Sumerian culture remained in southern Mesopotamia, even though rulers soon began expanding into neighboring areas. Neighboring Semitic groups, including the Akkadian speaking Semites (Assyrians, Babylonians) who lived alongside the Sumerians in Mesopotamia, adopted much of Sumerian culture for their own. The earliest ziggurats began near the end of the Early Dynastic Period, although architectural precursors in the form of raised platforms date back to the Ubaid period. The Sumerian King List dates to the early second millennium BC. It consists of a succession of royal dynasties from different Sumerian cities, ranging back into the Early Dynastic Period. Each dynasty rises to prominence and dominates the region, only to be replaced by the next. The document was used by later Mesopotamian kings to legitimize their rule. While some of the information in the list can be checked against other texts such as economic documents, much of it is probably purely fictional, and its use as a historical document is limited. Eannatum, the Sumerian king of Lagash, established the first verifiable empire in history in 2500 BC. The neighboring Elam, in modern Iran, was also part of the early urbanization during the Chalcolithic period. Elamite states were among the leading political forces of the Ancient Near East. The emergence of Elamite written records from around 3200 BC also parallels Sumerian history, where slightly earlier records have been found. During the 3rd millennium BC, there developed a very intimate cultural symbiosis between the Sumerians and the Akkadians. Akkadian gradually replaced Sumerian as a spoken language somewhere between the 3rd and the 2nd millennia BC. The Semitic-speaking Akkadian empire emerged around 2350 BC under Sargon the Great. The Akkadian Empire reached its political peak between the 24th and 22nd centuries BC. Under Sargon and his successors, the Akkadian language was briefly imposed on neighboring conquered states such as Elam and Gutium. After the fall of the Akkadian Empire and the overthrow of the Gutians, there was a brief reassertion of Sumerian dominance in Mesopotamia under the Third Dynasty of Ur. After the final collapse of Sumerian hegemony in Mesopotamia around 2004 BC, the Semitic Akkadian people of Mesopotamia eventually coalesced into two major Akkadian-speaking nations: Assyria in the north (whose earliest kings date to the 25th century BC), and, a few centuries later, Babylonia in the south, both of which (Assyria in particular) would go on to form powerful empires between the 20th and 6th centuries BC. The Sumerians were eventually absorbed into the Semitic Assyrian-Babylonian population.
