{{History of Iraq|File:Standard_of_Ur_-_War_-_Detail_Middle_Left.jpg}}
'''Sumer''' ({{IPAc-en|ˈ|s|uː|m|ər|}}) is the earliest known [[civilization]], located in the historical region of southern [[Mesopotamia]] (now south-central [[Iraq]]), emerging during the [[Chalcolithic]] and [[Early Bronze Age|early Bronze]] Ages between the sixth and fifth millennium BC. Like nearby [[Elam]], it is one of the [[Cradle of civilization|cradles of civilization]], along with [[ancient Egypt|Egypt]], the [[Indus Valley Civilisation|Indus Valley]], the [[Erligang culture]] of the Yellow River valley, [[Caral-Supe civilization|Caral-Supe]], and [[Mesoamerica]]. Living along the valleys of the [[Tigris]] and [[Euphrates]] rivers, Sumerian farmers grew an abundance of grain and other crops, a surplus of which enabled them to form urban settlements. The world's earliest known texts come from the Sumerian cities of [[Uruk]] and [[Jemdet Nasr]], and date to between {{circa|3350|2500 BC}}, following a period of [[proto-writing]] {{circa|4000|2500 BC}}.

==Origins==
Most historians have suggested that Sumer was first permanently settled between {{circa|5500}} and {{circa|3300 BC}} by a [[West Asia]]n people who spoke the [[Sumerian language]] (pointing to the names of cities, rivers, basic occupations, etc., as evidence), a non-Semitic and non-[[Indo-European languages|Indo-European]] [[agglutinative language|agglutinative]] [[language isolate]].<ref name="SNK">{{cite book |last1=Kramer |first1=Samuel Noah |title=In the World of Sumer: An Autobiography |date=1988 |publisher=Wayne State University Press |isbn=978-0-8143-2121-8 |page=44 |url=https://books.google.com/books?id=KliA7MjJEDQC&pg=PA44 }}</ref><ref>{{Cite web|url=http://oi.uchicago.edu/OI/MUS/ED/TRC/MESO/writing.html|title=Ancient Mesopotamia.

Others have suggested that the Sumerians were a [[North Africa]]n people who migrated from the [[Green Sahara]] into the [[Middle East]] and were responsible for the spread of farming in the Middle East.<ref>{{Cite conference|url=https://books.google.com/books?id=MJWcSRSz9wEC&pg=PA22|title=Prehistoric Iberia: Genetics, Anthropology, and Linguistics |conference=International Conference on Prehistoric Iberia : Genetics, Anthropology, and Linguistics; November 16–17, 1998; Madrid, Spain |last1=Arnaiz-Villena|first1=Antonio|last2=Martínez-Laso|first2=Jorge|last3=Gómez-Casado|first3=Eduardo|date=2000|publisher=Springer Science & Business Media|isbn=978-0-306-46364-8|pages=22}}</ref> However, contrary evidence strongly suggests that the first farming originated in the [[Fertile Crescent]].<ref name="Genomic insights into the origin of">{{cite journal |last1=Lazaridis |first1=I. |last2=Nadel |first2=D. |last3=Rollefson |first3=G. |title=Genomic insights into the origin of farming in the ancient Near East |journal=Nature |date=2016 |volume=536 |issue=7617 |pages=419–424 |doi=10.1038/nature19310 |pmid=27459054 |url= |pmc=5003663 |bibcode=2016Natur.536..419L }}</ref> Although not specifically discussing Sumerians, Lazaridis et al. 2016 have suggested [[Haplogroup E-M215 (Y-DNA)|a partial North African origin]] for some pre-Semitic cultures of the Middle East, particularly [[Natufians]], after testing the genomes of Natufian and [[Pre-Pottery Neolithic]] culture-bearers.<ref name="Genomic insights into the origin of"/> Craniometric analysis has also suggested an affinity between Natufians and ancient North Africans.<ref>{{Cite journal|quote=Craniometric analyses have suggested an affinity between the Natufians and populations of north or sub-Saharan Africa, a result that finds some support from Y chromosome analysis which shows that the Natufians and successor Levantine Neolithic populations carried haplogroup E, of likely ultimate African origin, which has not been detected in other ancient males from West Eurasia.

Based on mentions of [[Dilmun]] as the "home city of the land of Sumer" in Sumerian legends and literature, other scholars have suggested the possibility that the Sumerians originated from Dilmun, which was theorized to be the island of [[Bahrain]] in the [[Persian Gulf]].<ref>{{Cite web |title=Sumerian Civilization |url=https://www.sjsu.edu/faculty/watkins/sumer.htm |access-date=2024-10-19 |publisher=San José State University}}</ref><ref>{{Cite magazine |date=April 18, 1960 |title=Science: Home City of Sumer? |url=https://time.com/archive/6811703/science-home-city-of-sumer/ |magazine=[[Time (magazine)|Time]] |access-date=October 19, 2024 |archive-date=December 7, 2024 |archive-url=https://web.archive.org/web/20241207050121/https://time.com/archive/6811703/science-home-city-of-sumer/ |url-status=dead }}</ref><ref>{{Cite book |url=https://books.google.com/books?id=KliA7MjJEDQC&pg=PA44 |title=In the World of Sumer: An Autobiography |date=1988 |publisher=Wayne State University Press |isbn=978-0-8143-2121-8 |language=en}}</ref> In Sumerian mythology, Dilmun was also mentioned as the home of deities such as [[Enki]].<ref>{{Cite web |title=Dilmun – Tilmun – Creation – Aliens – Middle East |website=Crystalinks |url=https://www.crystalinks.com/dilmun.html |access-date=2024-10-19 }}</ref><ref>{{Citation |title=Enki (Ea) in the mythology of creation |date=2015-10-01 |work=The God Enki in Sumerian Royal Ideology and Mythology |pages=139–188 |url=http://dx.doi.org/10.2307/j.ctvc16s63.14 |access-date=2024-10-19 |last=Harrassowitz |first=O.|doi=10.2307/j.ctvc16s63.14 |url-access=subscription }}</ref> The status of Dilmun as the Sumerians’ ancestral homeland has not been established, but archaeologists have found evidence of civilization in Bahrain, namely the existence of Mesopotamian-style round disks.<ref>{{Cite journal |date=1990-01-01 |title=Nimrod Before and After the Bible |url=https://www.cambridge.org/core/journals/harvard-theological-review/article/abs/nimrod-before-and-after-the-bible/0BC3FCE0DE038734776EDF2882A9580F |journal=Harvard Theological Review |language=en |volume=83 |issue=1 |pages=1–29 |doi=10.1017/S0017816000005502 |issn=1475-4517 |last1=Van Der Toorn |first1=K. |last2=Van Der Horst |first2=P.

Some scholars contest the idea of a Proto-Euphratean language or one substrate language; they think the Sumerian language may originally have been that of the [[hunting]] and [[fishing]] peoples who lived in the marshland and the [[Eastern Arabia|Eastern Arabia littoral region]] and were part of the Arabian [[bifacial]] culture.<ref>Margarethe Uepermann (2007), "Structuring the Late Stone Age of Southeastern Arabia".

Sumerian civilization took form in the [[Uruk period]] (4th millennium BC), continuing into the [[Jemdet Nasr period|Jemdet Nasr]] and [[Early Dynastic Period (Mesopotamia)|Early Dynastic]] periods. The Sumerian city of [[Eridu]], on the coast of the Persian Gulf, is considered to have been one of the [[List of oldest continuously inhabited cities|oldest cities]], where three separate cultures may have fused: that of peasant Ubaidian farmers, living in mud-brick huts and practicing irrigation; that of mobile nomadic Semitic pastoralists living in black tents and following herds of sheep and goats; and that of fisher folk, living in reed huts in the marshlands, who may have been the ancestors of the Sumerians.<ref name="Leick, Gwendolyn 2003">Leick, Gwendolyn (2003), "Mesopotamia, the Invention of the City" (Penguin)</ref>

Reliable historical records begin with [[Enmebaragesi]] ([[Early Dynastic Period (Mesopotamia)|Early Dynastic I]]). The Sumerians progressively lost control to Semitic states from the northwest. Sumer was conquered by the Semitic-speaking kings of the Akkadian Empire around 2270 BC ([[short chronology]]), but Sumerian continued as a [[sacred language]]. Native Sumerian rule re-emerged for about a century in the [[Third Dynasty of Ur]] at approximately 2100–2000 BC, but the Akkadian language also remained in use for some time.<ref name="Leick, Gwendolyn 2003" />

==Archeological discovery==
The Sumerians were entirely unknown during the early period of modern archeology. [[Jules Oppert]] was the first scholar to publish the word Sumer in a lecture on 17 January 1869. The first major excavations of Sumerian cities were in 1877 at [[Girsu]] by the French archeologist [[Ernest de Sarzec]], in 1889 at [[Nippur]] by [[John Punnett Peters]] from the [[University of Pennsylvania]] between 1889 and 1900, and in [[Shuruppak]] by German archeologist [[Robert Koldewey]] in 1902–1903. Major publications of these finds were "''Decouvertes en Chaldée par Ernest de Sarzec''" by [[Léon Heuzey]] in 1884, "''Les Inscriptions de Sumer et d'Akkad''" by [[François Thureau-Dangin]] in 1905, and "''Grundzüge der sumerischen Grammatik''" on Sumerian grammar by [[Arno Poebel]] in 1923.<ref>Kramer (1963), The Sumerians, pp. 20–26.</ref>

In the late 4th millennium BC, Sumer was divided into many independent [[city-state]]s, which were divided by canals and boundary stones. Each was centered on a temple dedicated to the particular patron god or goddess of the city and ruled over by a priestly governor ([[Ensí|ensi]]) or by a king ([[LUGAL|lugal]]) who was intimately tied to the city's religious rites.

The Sumerian city-states rose to power during the prehistoric Ubaid and Uruk periods. Sumerian written history reaches back to the 27th century BC and before, but the historical record remains obscure until the Early Dynastic III period, {{circa|23rd century BC}}, when the language of the written records becomes easier to decipher, which has allowed archaeologists to read contemporary records and inscriptions.

The [[Akkadian Empire]] was the first state that successfully united larger parts of Mesopotamia in the 23rd century BC. After the [[Gutian period]], the [[Third Dynasty of Ur|Ur III kingdom]] similarly united parts of northern and southern Mesopotamia. It ended in the face of [[Amorites|Amorite]] incursions at the beginning of the second millennium BC. The Amorite "dynasty of [[Isin]]" persisted until {{circa|1700 BC}}, when Mesopotamia was united under [[Babylonia]]n rule.

===Ubaid period===
{{Main|Ubaid period}}
[[Image:Frieze-group-3-example1.jpg|thumb|right|A pottery jar from the [[Late Ubaid Period]]]]
The Ubaid period is marked by a distinctive style of fine quality painted pottery which spread throughout Mesopotamia and the [[Persian Gulf]]. The oldest evidence for occupation comes from [[Tell el-'Oueili]], but, given that environmental conditions in southern Mesopotamia were favourable to human occupation well before the Ubaid period, it is likely that older sites exist but have not yet been found. It appears that this culture was derived from the [[Samarra]]n culture from northern Mesopotamia. It is not known whether or not these were the actual Sumerians who are identified with the later Uruk culture. The story of the passing of the gifts of civilization ([[me (mythology)|''me'']]) to [[Inanna]], goddess of Uruk and of love and war, by [[Enki]], god of wisdom and chief god of Eridu, may reflect the transition from Eridu to Uruk.<ref name="WolksteinKramer1983">{{cite book|last1=Wolkstein|first1=Diane|url=https://archive.org/details/inanna00dian/page/174/mode/2up|title=Inanna: Queen of Heaven and Earth: Her Stories and Hymns from Sumer|last2=Kramer|first2=Samuel Noah|publisher=Harper & Row|others=Elizabeth Williams-Forte|year=1983|isbn=978-0-06-014713-6|location=New York|pages=174}}</ref>

===Uruk period===
{{Main|Uruk period}}
The archaeological transition from the Ubaid period to the Uruk period is marked by a gradual shift from painted pottery domestically produced on a slow [[Potter's wheel|wheel]] to a great variety of unpainted pottery mass-produced by specialists on fast wheels. The Uruk period is a continuation and an outgrowth of Ubaid with pottery being the main visible change.<ref>{{cite book |last1=Henrickson |first1=Elizabeth F. |url=https://books.google.com/books?id=gnpyREWsfG0C&pg=PA353 |title=Upon this Foundation: The N̜baid Reconsidered : Proceedings from the U̜baid Symposium, Elsinore, May 30th–June1st, 1988 |last2=Thuesen |first2=Ingolf |last3=Thuesen |first3=I. |publisher=Museum Tusculanum Press |year=1989 |isbn=978-87-7289-070-8 |page=353}}</ref><ref>{{cite book |author=Glassner |first=Jean-Jacques |url=https://books.google.com/books?id=fhMTRcUm9WsC&pg=PA31 |title=The Invention of Cuneiform: Writing in Sumer |publisher=JHU Press |year=2003 |isbn=978-0-8018-7389-8 |page=31}}</ref>

By the time of the Uruk period, c. 4100–2900 BC calibrated, the volume of trade goods transported along the canals and rivers of southern Mesopotamia facilitated the rise of many large, [[social stratification|stratified]], temple-centered cities, with populations of over 10,000 people, where centralized administrations employed specialized workers. It is fairly certain that it was during the Uruk period that Sumerian cities began to make use of [[Slavery in antiquity|slave labour]] captured from the hill country, and there is ample evidence for captured slaves as workers in the earliest texts. Artifacts, and even colonies of this Uruk civilization have been found over a wide area—from the [[Taurus Mountains]] in [[Turkey]], to the [[Mediterranean Sea]] in the west, and as far east as western [[Iran]].<ref name="Algaze, Guillermo 2005">[[Guillermo Algaze|Algaze, Guillermo]] (2005). ''[[iarchive:urukworldsystemd0000alga|The Uruk World System: The Dynamics of Expansion of Early Mesopotamian Civilization]]'', Second Edition, University of Chicago Press.</ref>{{Rp|2–3}}

The Uruk period civilization, exported by Sumerian traders and colonists, like that found at [[Tell Brak]], had an effect on all surrounding peoples, who gradually evolved their own comparable, competing economies and cultures. The cities of Sumer could not maintain remote, long-distance colonies by military force.<ref name="Algaze, Guillermo 2005"/>{{Page needed|date=August 2021}}

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.<ref name="Jacobsen">Jacobsen, Thorkild (Ed) (1939),"The Sumerian King List" (Oriental Institute of the University of Chicago; Assyriological Studies, No. 11., 1939).</ref> It is quite possible that the later Sumerian [[Pantheon (gods)|pantheon]] was modeled upon this political structure. There was little evidence of organized warfare or professional soldiers during the Uruk period, and towns were generally unwalled. During this period Uruk became the most urbanized city in the world, surpassing for the first time 50,000 inhabitants.

The ancient [[Sumerian King List|Sumerian king list]] includes the early dynasties of several prominent cities from this period. The first set of names on the list is of kings said to have reigned before a major flood occurred. These early names may be fictional, and include some legendary and mythological figures, such as [[Alulim]] and [[Dumuzid, the Shepherd|Dumuzid]].<ref name=Jacobsen/>

The end of the Uruk period coincided with the [[Piora oscillation]], a dry period from c. 3200–2900 BC that marked the end of a long wetter, warmer climate period from about 9,000 to 5,000 years ago, called the [[Holocene climatic optimum]].<ref>Lamb, Hubert H. (1995). ''Climate, History, and the Modern World''. London: Routledge. {{ISBN|0-415-12735-1}}.</ref>

===Early Dynastic Period===
{{Main|Early Dynastic Period (Mesopotamia)|First Dynasty of Ur}}
[[File:Meskalamdug helmet British Museum electrotype copy original is in the Iraq Museum, Bagdad.jpg|thumb|Golden helmet of [[Meskalamdug]], possible founder of the [[First Dynasty of Ur]], 26th century BC]]
The dynastic period begins c. 2900 BC and was associated with a shift 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)<ref>Jacobsen, Thorkild (1976), "The Harps that Once...; Sumerian Poetry in Translation" and "Treasures of Darkness: a history of Mesopotamian Religion".</ref> towards a more secular Lugal (Lu = man, Gal = great) and includes such legendary patriarchal figures as [[Dumuzid]], [[Lugalbanda]] and [[Gilgamesh]]—who reigned shortly before the historic record opens c. 2900 BC, when the now deciphered 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, and neighboring Semitic groups adopted much of Sumerian culture for their own.

The earliest dynastic king on the Sumerian king list whose name is known from any other legendary source is [[Etana]], 13th king of the first dynasty of [[Kish (Sumer)|Kish]]. The earliest king authenticated through archaeological evidence is [[Enmebaragesi]] of Kish (Early Dynastic I), whose name is mentioned in the ''[[Epic of Gilgamesh]]''—leading to the suggestion that Gilgamesh himself might have been a historical king of Uruk. As the ''Epic of Gilgamesh'' shows, this period was associated with increased war. Cities became walled, and increased in size as undefended villages in southern Mesopotamia disappeared. Both Gilgamesh and one of his predecessors Enmerkar are credited with having built the walls of Uruk.<ref>George, Andrew (Translator) (2003), "The Epic of Gilgamesh" (Penguin Classics).</ref>

====1st Dynasty of Lagash====
[[File:Stele of Vultures detail 02.jpg|thumb|A fragment of [[Eannatum]]'s [[Stele of the Vultures]]]]
{{Main|Lagash}}
The dynasty of Lagash (c. 2500–2270 BC), though omitted from the king list, is well attested through several important monuments and many archaeological finds.

Although short-lived, one of the first empires known to history was that of [[Eannatum]] of Lagash, who annexed practically all of Sumer, including Kish, Uruk, [[Ur]], and [[Larsa]], and reduced to tribute the city-state of [[Umma]], arch-rival of Lagash. In addition, his realm extended to parts of [[Elam]] and along the [[Persian Gulf]]. He seems to have used terror as a matter of policy.<ref name=roux1993>{{cite book |last=Roux |first=Georges |author-link=Georges Roux (assyriologist) |year=1993 |title=Ancient Iraq |location=Harmondsworth |publisher=Penguin |isbn=978-0-14-012523-8 |url-access=registration |url=https://archive.org/details/ancientiraq00roux }}</ref> Eannatum's [[Stele of the Vultures]] depicts vultures pecking at the severed heads and other body parts of his enemies. His empire collapsed shortly after his death.

Later, [[Lugal-zage-si]], the priest-king of Umma, overthrew the primacy of the Lagash dynasty in the area, then conquered Uruk, making it his capital, and claimed an empire extending from the Persian Gulf to the Mediterranean. He was the last ethnically Sumerian king before [[Sargon of Akkad]].<ref name="Leick, Gwendolyn 2003"/>

===Akkadian Empire===
{{Main|Akkadian Empire}}
[[File:Prisoners on the victory stele of an Akkadian king circa 2300 BCE Louvre Museum Sb 3.jpg|thumb|upright=0.9|Sumerian prisoners on a victory stele of the Akkadian king [[Sargon of Akkad|Sargon]], {{circa|2300 BC}}.<ref name="ArchaeologyofElam" /><ref name="TwoSteles" /> Louvre Museum.]]

The Akkadian Empire dates to {{circa|2334}}–2154 BC ([[middle chronology]]), founded by [[Sargon of Akkad]]. The [[East Semitic languages|Eastern Semitic]] [[Akkadian language]] is first attested in proper names of the kings of Kish {{circa|2800 BC}},<ref name=roux1993/> preserved in later king lists. There are texts written entirely in Old Akkadian dating from {{circa|2500 BC}}. Use of Old Akkadian was at its peak during the rule of [[Sargon of Akkad]] ({{circa|2334}}–2279 BC), but even then most administrative tablets continued to be written in Sumerian, the language used by the scribes. Gelb and Westenholz differentiate three stages of Old Akkadian: that of the pre-Sargonic era, that of the Akkadian empire, and that of the Ur III period that followed it.<ref name="auto">T. Jacobsen. ''Toward the Image of Tammuz and Other Essays on Mesopotamian History and Culture.''</ref>

Akkadian and Sumerian coexisted as vernacular languages for about one thousand years, but by around 1800 BC, Sumerian was becoming more of a literary language familiar mainly only to scholars and scribes. [[Thorkild Jacobsen]] has argued that there is little break in historical continuity between the pre- and post-Sargon periods, and that too much emphasis has been placed on the perception of a "Semitic vs. Sumerian" conflict.<ref name="auto"/> It is certain that Akkadian was also briefly imposed on neighboring parts of Elam that were previously conquered, by Sargon.

===Gutian period===
{{Main|Gutian dynasty of Sumer}}
c. 2193–2119 BC (middle chronology)

The Gutian people were a group of semi nomadic peoples who originated from the Zagros Mountains of northeastern Mesopotamia. The [[Gutian Dynasty]] rose to prominence during the decline and fall of [[Akkadian Empire]] under poorly understood circumstances. Following the death of Akkad's last powerful ruler, [[Shar-Kali-Sharri]] (c. 2218 - 2193 BC), the Gutians gradually took control of Akkadian centers, including the capital Akkad in 2193 BC. The eventual fall of the Akkadian Empire in 2154 BC marked the peak of Gutian strength. There is very little information on the Gutian rulers and people, it is often considered to be a dark age of the Sumerians, an intermediary between the [[Akkadian Empire]] and the [[Third Dynasty of Ur]]. The Gutian period came to an end with the rise of [[Utu-hengal]] of Uruk (c. 2119 - 2112 BC), who defeated the last Gutian king, [[Tirigan]], briefly establishing the short lived 5th dynasty of Uruk. Shortly after, [[Ur-Nammu]] of Ur (c. 2112 - 2094 BC) would overthrow [[Utu-hengal]]'s kingdom and establish the [[Third Dynasty of Ur]] in 2112 BC. 

====2nd Dynasty of Lagash====

{{Main|Lagash}}
{{circa|2200}}–2110 BC (middle chronology)

Following the downfall of the Akkadian Empire at the hands of [[Gutian dynasty of Sumer|Gutians]], another native Sumerian ruler, [[Gudea]] of Lagash, rose to local prominence and continued the practices of the [[List of kings of Akkad#Sargonic dynasty (c. 2334 – 2193 BC)|Sargonic kings]]' claims to divinity.

The previous Lagash dynasty, Gudea and his descendants also promoted artistic development and left a large number of archaeological artifacts.

===Ur III period===
{{Main|Third Dynasty of Ur}}
Later, the Third Dynasty of Ur under [[Ur-Nammu]] and [[Shulgi]] (c. 2112–2004 BC, middle chronology), whose power extended as far as southern [[Assyria]], has been erroneously called a "Sumerian renaissance" in the past.<ref>{{Cite book |last=Cooper |first=Jerrold S. |title=Problems of canonicity and identity formation in ancient Egypt and Mesopotamia |date=2016 |others=Kim Ryholt, Gojko Barjamovic, Københavns universitet, Denmark.

The last of these eventually came to briefly dominate the south of Mesopotamia as the [[Babylonian Empire]], just as the [[Old Assyrian Empire]] had already done in the north from the late 21st century BC. The Sumerian language continued as a sacerdotal language taught in schools in Babylonia and Assyria, much as Latin was used in the Medieval period, for as long as cuneiform was used.

===Fall and transmission===
This period is generally taken to coincide with a major shift in population from southern Mesopotamia toward the north. Ecologically, the agricultural productivity of the Sumerian lands was being compromised as a result of rising salinity. [[Soil salinity]] in this region had been long recognized as a major problem.<ref>{{Cite Q|Q34677808}}</ref> Poorly drained irrigated soils, in an arid climate with high levels of evaporation, led to the buildup of dissolved salts in the soil, eventually reducing agricultural yields severely.<ref name="auto1">{{cite journal|last=Thompson |first=William R. |year=2004 |title=Complexity, Diminishing Marginal Returns and Serial Mesopotamian Fragmentation |journal=Journal of World-Systems Research |url=http://jwsr.ucr.edu/archive/vol10/number3/pdf/jwsr-v10n3-thompson.pdf |doi=10.5195/jwsr.2004.288 |volume=10 |pages=612–652 |issue=3 |url-status=unfit |archive-url=https://web.archive.org/web/20120219134627/http://jwsr.ucr.edu/archive/vol10/number3/pdf/jwsr-v10n3-thompson.pdf |archive-date=February 19, 2012 |doi-access=free }}</ref>

During the Akkadian and [[Ur III]] phases, there was a shift from the cultivation of [[wheat]] to the more salt-tolerant [[barley]], but this was insufficient, and during the period from 2100 BC to 1700 BC, it is estimated that the population in this area declined by nearly three-fifths.<ref name="auto1"/> This greatly upset the balance of power within the region, weakening the areas where Sumerian was spoken, and comparatively strengthening those where Akkadian was the major language. Henceforth, Sumerian remained only a [[literary language|literary]] and [[Sacred language|liturgical]] language, similar to the position occupied by [[Latin]] in [[Middle Ages|medieval]] Europe.

Following an Elamite invasion and sack of Ur during the rule of [[Ibbi-Sin]] (c. 2028–2004 BC),{{citation needed|reason=Doesn't cite any evidence of sack of Ur?|date=October 2015}} Sumer came under Amorite rule (taken to introduce the [[Middle Bronze Age]]). The independent Amorite states of the 20th to 18th centuries are summarized as the "[[Dynasty of Isin]]" in the Sumerian king list, ending with the rise of Babylonia under [[Hammurabi]] c. 1800 BC.

Later rulers who dominated Assyria and Babylonia occasionally assumed the old Sargonic title "King of Sumer and Akkad", such as [[Tukulti-Ninurta I]] of Assyria after c. 1225 BC.

==Population==
Uruk, one of Sumer's largest cities, has been estimated to have had a population of 50,000–80,000 at its height.<ref>{{Cite web|url=https://proteus.brown.edu/mesopotamianarchaeology/Home|archive-url=https://archive.today/20150411005800/http://proteus.brown.edu/mesopotamianarchaeology/Home|url-status=dead|title=The Archaeology of Mesopotamia: Home |access-date=2019-07-21|archive-date=2015-04-11}}</ref> Given the other cities in Sumer, and the large agricultural population, a rough estimate for Sumer's population might be 0.8 million to 1.5 million.

The Sumerians spoke a [[language isolate]]. A number of linguists have claimed to be able to detect a [[substrate language]] of unknown classification beneath Sumerian, because names of some of Sumer's major cities are not Sumerian, revealing influences of earlier inhabitants.<ref name="Nemet-Nejat1998">{{cite book |author=Nemet-Nejat |first=Karen Rhea |url=https://archive.org/details/dailylifeinancie00neme |title=Daily life in ancient Mesopotamia |publisher=Greenwood Publishing Group |year=1998 |isbn=978-0-313-29497-6 |page=[https://archive.org/details/dailylifeinancie00neme/page/13 13] |access-date=29 November 2011 |url-access=registration}}</ref> However, the [[archaeological record]] shows clear uninterrupted cultural continuity from the time of the early [[Ubaid period]] (5300–4700 BC [[Radiocarbon dating|C-14]]) settlements in southern Mesopotamia. The Sumerian people who settled here, farmed the lands in this region that were made fertile by silt deposited by the [[Tigris]] and the [[Euphrates]].

Some archaeologists have speculated that the original speakers of ancient Sumerian may have been farmers, who moved down from the north of Mesopotamia after perfecting irrigation agriculture there. The Ubaid period pottery of southern Mesopotamia has been connected via [[Choga Mami]] transitional ware, to the pottery of the [[Samarra]] period culture ({{circa|5700}}–4900 BC [[Radiocarbon dating|C-14]]) in the north, who were the first to practice a primitive form of irrigation agriculture along the middle Tigris River and its tributaries. The connection is most clearly seen at [[Tell el-'Oueili]] near [[Larsa]], excavated by the French in the 1980s, where eight levels yielded pre-Ubaid pottery resembling Samarran ware. According to this theory, farming peoples spread down into southern Mesopotamia because they had developed a temple-centered social organization for mobilizing labor and technology for water control, enabling them to survive and prosper in a difficult environment.{{Citation needed|date=June 2011}}

Others have suggested a continuity of Sumerians, from the indigenous hunter-fisherfolk traditions, associated with the bifacial assemblages found on the Arabian littoral. [[Juris Zarins]] believes the Sumerians may have been the people living in the Persian Gulf region before it flooded at the end of the last Ice Age.{{citation needed|date=July 2022}}

[[File:Reconstructed sumerian headgear necklaces british museum.JPG|thumb|upright=.6|A reconstruction in the British Museum of headgear and necklaces worn by the women at the [[Royal Cemetery at Ur]].]]
In the early Sumerian period, the primitive pictograms suggest<ref name="Sayce"/> that
* "Pottery was very plentiful, and the forms of the vases, bowls and dishes were manifold; there were special jars for honey, butter, oil and wine, which was probably made from dates. Some of the vases had pointed feet, and stood on stands with crossed legs; others were flat-bottomed, and were set on square or rectangular frames of wood. The oil-jars, and probably others also, were sealed with clay, precisely as in early [[Egypt]]. Vases and dishes of stone were made in imitation of those of clay."
* "A feathered head-dress was worn. Beds, stools and chairs were used, with carved legs resembling those of an ox. There were fire-places and fire-altars."
* "Knives, drills, wedges and an instrument that looks like a saw were all known. While spears, bows, arrows, and daggers (but not swords) were employed in war."
* "Tablets were used for writing purposes. Daggers with metal blades and wooden handles were worn, and copper was hammered into plates, while necklaces or collars were made of gold."
* "Time was reckoned in lunar months."

There is considerable evidence concerning [[Sumerian music]]. [[Lyres]] and flutes were played, among the best-known examples being the [[Lyres of Ur]].<ref name="Goss_2017_mesopotamian_flutes">{{cite web |last=Goss |first=Clint |title=Flutes of Gilgamesh and Ancient Mesopotamia |url=http://www.Flutopedia.com/mesopotamian_flutes.htm |date=15 April 2017 |website=Flutopedia |access-date=14 June 2017 }}</ref>

Sumerian culture was male-dominated and stratified. The [[Code of Ur-Nammu]], the oldest such codification yet discovered, dating to the Ur III, reveals a glimpse at societal structure in late Sumerian law. Beneath the ''lu-gal'' ("great man" or king), all members of society belonged to one of two basic strata: The "''lu''" or free person, and the slave (male, ''arad''; female ''geme''). The son of a ''lu'' was called a ''dumu-nita'' until he married.

In early Sumer women played an important public rule as priestesses. They could also own property, transact business and had their rights protected by the courts. Sons and daughters inherited property on equal terms. The status of women deteriorated in the centuries after 2300 BC. Their right to dispose of their property was limited, and the female deities also lost their former importance.<ref>{{cite book |last1=Baring |first1=Anne |last2=Cashford |first2=Jules |title=The Myth of the Goddess Evolution of an Image |date=1993 |publisher=Penguin Books Limited |isbn=9780141941400 |page=159}}</ref><ref>{{cite book |last1=Glassman |first1=Ronald M. |title=The Origins of Democracy in Tribes, City-States and Nation-States |date=2017 |publisher=Springer International Publishing |isbn=9783319516950 |page=344}}</ref>

===Language and writing===
{{Main|Sumerian language|Cuneiform}}
{{further|History of writing}}
[[File:P1150884_Louvre_Uruk_III_tablette_écriture_précunéiforme_AO19936_rwk.jpg|thumb|A tablet with pictographic pre-cuneiform writing. Late 4th millennium BC, limestone. Height: 4.5 cm, width: 4.3 cm, depth: 2.4 cm. The [[Louvre]]]]
The most important archaeological discoveries in Sumer are a large number of [[clay tablet]]s written in [[cuneiform script]]. Sumerian writing is considered to be a great milestone in the development of humanity's ability to not only create historical records but also in creating pieces of literature, both in the form of poetic epics and stories as well as prayers and laws.

Although the writing system was first [[hieroglyphic]] using [[ideogram]]s, [[logogram|logosyllabic]] cuneiform soon followed.{{citation needed|date=October 2022}}

Triangular or wedge-shaped reeds were used to write on moist clay. A large body of hundreds of thousands of texts in the Sumerian language have survived, including personal and business letters, receipts, [[lexical lists]], laws, hymns, prayers, stories, and daily records. Full libraries of clay tablets have been found. Monumental inscriptions and texts on different objects, like statues or bricks, are also very common. Many texts survive in multiple copies because they were repeatedly transcribed by scribes in training. Sumerian continued to be the language of religion and law in Mesopotamia long after Semitic speakers had become dominant.

A prime example of cuneiform writing is a lengthy poem that was discovered in the ruins of Uruk. The ''[[Epic of Gilgamesh]]'' was written in the standard Sumerian cuneiform. It tells of a king from the early Dynastic II period named Gilgamesh or "Bilgamesh" in Sumerian. The story relates the fictional adventures of Gilgamesh and his companion, [[Enkidu]]. It was laid out on several clay tablets and is thought to be the earliest known surviving example of fictional literature.

The Sumerian language is generally regarded as a [[language isolate]] in [[linguistics]], because it belongs to no known language family. Akkadian, by contrast, belongs to the Semitic branch of the [[Afroasiatic languages]]. There have been many failed attempts to connect Sumerian to other [[language family|language families]]. It is an [[agglutinative language]]. In other words, [[morpheme]]s ("units of meaning") are added together to create words, unlike [[analytic languages]] where morphemes are purely added together to create sentences. Some authors have proposed that there may be evidence of a [[Substratum (linguistics)|substratum]] or adstratum language for geographic features and various crafts and agricultural activities, called variously [[Proto-Euphratean]] or Proto Tigrean, but this is disputed by others.

Understanding Sumerian texts today can be problematic. Most difficult are the earliest texts, which in many cases do not give the full grammatical structure of the language and seem to have been used as an "[[aide-mémoire]]" for knowledgeable scribes.<ref>{{Cite book|title=The Oxford Handbook of the History of Linguistics|last=Allan|first=Keith|publisher=Oxford University Press|year=2013|isbn=978-0-19-164343-9|location=Oxford|pages=56–57}}</ref>

Akkadian gradually replaced Sumerian as a spoken language somewhere around the turn of the 3rd and the 2nd millennium BC.<ref name="woods">Woods, C. 2006.

The Sumerians credited their divinities for all matters pertaining to them and exhibited humility in the face of cosmic forces, such as [[death]] and [[divine wrath]].<ref name=Kramer1963/>{{rp|3–4}}

Sumerian religion seems to have been founded upon two separate [[Cosmogeny|cosmogenic]] myths. The first saw creation as the result of a series of ''[[hieros gamos|hieroi gamoi]]'' or sacred marriages, involving the reconciliation of opposites, postulated as a coming together of male and female divine beings, the gods.

This pattern continued to influence regional Mesopotamian myths. Thus, in the later Akkadian [[Enuma Elish]], creation was seen as the union of fresh and salt water, between male [[Abzu]], and female [[Tiamat]]. The products of that union, [[Lahm]] and Lahmu, "the muddy ones", were titles given to the gate keepers of the E-Abzu temple of [[Enki]] in [[Eridu]], the first Sumerian city.

Mirroring the way that muddy islands emerge from the confluence of fresh and salty water at the mouth of the Euphrates, where the river deposits its load of silt, a second hieros gamos supposedly resulted in the creation of Anshar and Kishar, the "sky-pivot" (or axle), and the "earth pivot", parents in turn of [[Anu]] (the sky) and [[Ki (goddess)|Ki]] (the earth).

Another important Sumerian hieros gamos was that between Ki, here known as [[Ninhursag]] or "Lady of the Mountains", and Enki of Eridu, the god of fresh water which brought forth greenery and pasture.

At an early stage, following the dawn of recorded history, [[Nippur]], in central Mesopotamia, replaced Eridu in the south as the primary temple city, whose priests exercised political [[hegemony]] on the other city-states. Nippur retained this status throughout the Sumerian period.

====Deities====
[[File:Ea (Babilonian) - EnKi (Sumerian).jpg|thumb|upright=1.3|Akkadian cylinder seal from sometime around 2300 BC or thereabouts depicting the deities [[Inanna]], [[Utu]], [[Enki]], and [[Isimud]]]]
Sumerians believed in an anthropomorphic polytheism, or the belief in many gods in human form. There was no common set of gods; each city-state had its own patrons, temples, and priest-kings. Nonetheless, these were not exclusive; the gods of one city were often acknowledged elsewhere. Sumerian speakers were among the earliest people to record their beliefs in writing, and were a major inspiration in later [[Mesopotamian mythology]], [[religion]], and [[astrology]].

The Sumerians worshiped:
* [[Anu|An]] as the full-time god equivalent to heaven; indeed, the word ''an'' in Sumerian means sky and his consort [[Ki (goddess)|Ki]], means earth.
* [[Enki]] in the south at the temple in Eridu. Enki was the god of beneficence and of wisdom, ruler of the freshwater depths beneath the earth, a healer and friend to humanity who in Sumerian myth was thought to have given humans the arts and sciences, the industries and manners of civilization; the first law book was considered his creation.
* [[Enlil]] was the god of storm, wind, and rain.<ref name="ColemanDavidson2015">{{citation |last1=Coleman |first1=J.

[[File:Genealogy of Sumero-Akkadian Gods.jpg|thumb|upright=2.05|Sumero-early Akkadian [[Pantheon (gods)|pantheon]]]]

These [[deity|deities]] formed the main pantheon, and in addition to this there were hundreds of other minor gods. Sumerian gods were often associated with different cities, and their religious importance often waxed and waned with those cities' political power. The gods were said to have created human beings from clay for the purpose of serving them. The temples organized the mass labour projects needed for irrigation agriculture. Citizens had a labor duty to the temple, though they could avoid it by a payment of silver.

====Cosmology====
Sumerians envisioned Earth to be a rectangular field with four corners.<ref name=":0" /> The Sumerian [[afterlife]] involved a descent into a gloomy [[Sumerian nether-world|netherworld]] to spend eternity in a wretched [[existence]] as a [[Gidim]] (ghost).<ref name=":0">{{cite book |last1=Black |first1=Jeremy |author-link1=Jeremy Black (assyriologist) |last2=Green | first2=Anthony |title= Gods, Demons, and Symbols of Ancient Mesopotamia: An Illustrated Dictionary |date=1992 |publisher=University of Texas Press |isbn=978-0-292-70794-8}}</ref>

The universe was divided into four quarters:
* To the north were the hill-dwelling [[Subartu]], who were periodically raided for slaves, timber, and other raw materials.<ref>Whatever the assertions of cosmography here, when modern-day archaeologists carve out areas of exploration based on physical-remains and other data, there is an emphasis on three, ''vide'' Marcella Frangipane, "Different Trajectories in State Formation in Greater Mesopotamia: A View from Arslantepe (Turkey)", ''Journal of Archaeological Research'' 26 (2018): 3–63. https://doi.org/10.1007/s10814-017-9106-2. {{Webarchive|url=https://web.archive.org/web/20221123080651/https://link.springer.com/article/10.1007/s10814-017-9106-2|date=2022-11-23}}: "southern Mesopotamia, northern Mesopotamia, and [to the west] Upper Euphrates valley" (3), with no reference to any of these proper-names.</ref>
* To the west were the tent-dwelling [[Amorite|Martu]], ancient Semitic-speaking peoples living as pastoral nomads tending herds of sheep and goats.
* To the south was the land of [[Dilmun]], a trading state associated with the land of the dead and the place of creation.<ref name="Carl Phillips 2013">Geoffrey Bibby and Carl Phillips, ''Looking for Dilmun'' (London, England: Stacey International, 1996; reprinted London, England: Knopf, 2013). {{ISBN|978-0-905743-90-5}}.</ref>
* To the east were the [[Elamites]], a rival people with whom the Sumerians were frequently at war.

Their known world extended from ''The Upper Sea'' or Mediterranean coastline, to ''The Lower Sea'', the [[Persian Gulf]] and the land of [[Meluhha]] (probably the [[Indus Valley]]) and [[Majan (civilization)|Magan]] ([[Oman]]), famed for its copper ores.

====Temple and temple organisation====
[[Ziggurat]]s (Sumerian temples) each had an individual name and contained a forecourt with a central pond for purification.<ref>Leick, Gwendolyn (2003), Mesopotamia: The Invention of the City' (Penguin).</ref> The temple itself had a central [[nave]] with aisles along either side. Flanking the aisles were rooms for the priests. At one end stood a [[podium]] and a [[mudbrick]] table for animal and vegetable [[sacrifice]]s. [[Granary|Granaries]] and [[Warehouse|storehouses]] were usually located near the temples. After a time the Sumerians began to place the temples on top of multi-layered square constructions built as a series of rising terraces, giving rise to the Ziggurat style.<ref>Mark M. Jarzombek and Vikramaditya Prakash, ''A Global History of Architecture'' (London, England: Wiley, 2011), pp. 33–39. {{ISBN|978-0-470-90248-6}}.</ref>

====Funerary practices====
It was believed that when people died, they would be confined to a gloomy world of [[Ereshkigal]], whose realm was guarded by gateways with various monsters designed to prevent people entering or leaving. The dead were buried outside the city walls in graveyards where a small mound covered the corpse, along with offerings to monsters and a small amount of food. Those who could afford it sought burial at Dilmun.<ref name="Carl Phillips 2013"/> [[Human sacrifice]] was found in the death pits at the Ur royal cemetery where Queen [[Puabi]] was accompanied in death by her servants.

===Agriculture and hunting===
{{further|Agriculture in Mesopotamia}}
The Sumerians adopted an agricultural lifestyle perhaps as early as {{Circa|5000}}–4500 BC. The region demonstrated a number of core agricultural techniques, including organized [[irrigation]], large-scale intensive cultivation of land, [[monocropping]] involving the use of [[plough]] agriculture, and the use of an agricultural [[Division of labour|specialized labour force]] under bureaucratic control. The necessity to manage temple accounts with this organization led to the development of [[history of writing|writing]] (c. 3500 BC).

[[File:Ur mosaic.jpg|thumb|upright=1.35|From the royal tombs of [[Ur]], made of [[lapis lazuli]] and shell, shows peacetime]]

In the early Sumerian Uruk period, the primitive pictograms suggest that [[sheep]], [[goat]]s, [[cattle]], and [[pig]]s were domesticated. They used [[ox]]en as their primary beasts of burden and [[donkey]]s or [[equids]] as their primary transport animal and "woollen clothing as well as rugs were made from the wool or hair of the animals. ... By the side of the house was an enclosed garden planted with trees and other plants; wheat and probably other [[cereal]]s were sown in the fields, and the ''[[shaduf]]'' was already employed for the purpose of irrigation. Plants were also grown in pots or vases."<ref name="Sayce"/>

[[File:Issue of barley rations.JPG|thumb|An account of barley rations issued monthly to adults and children written in [[cuneiform script]] on a clay tablet, written in year 4 of King [[Urukagina]], {{circa|2350 BC}}]]

The Sumerians were one of the first known [[beer]]-drinking societies. Cereals were plentiful and were the key ingredient in their early brew. They brewed multiple kinds of beer consisting of wheat, barley, and mixed grain beers. Beer brewing was very important to the Sumerians. It was referenced in the Epic of Gilgamesh when Enkidu was introduced to the food and beer of Gilgamesh's people: "Drink the beer, as is the custom of the land... He drank the beer-seven jugs! and became expansive and sang with joy!"<ref>{{cite book|last1=Gately|first1=Iain|title=Drink: A Cultural History of Alcohol|publisher=Gotham Books|isbn=978-1-59240-303-5|page=[https://archive.org/details/drinkculturalhis00gate_0/page/5 5]|year=2008|url=https://archive.org/details/drinkculturalhis00gate_0/page/5}}</ref>

The Sumerians practiced similar irrigation techniques as those used in Egypt.<ref>{{cite book| last = Mackenzie| first = Donald Alexander| year = 1927 | title = Footprints of Early Man| publisher = Blackie & Son Limited}}</ref> American anthropologist [[Robert McCormick Adams]] says that irrigation development was associated with urbanization,<ref>{{cite book| last = Adams| first = R. McC.| year = 1981 | title = Heartland of Cities| publisher = University of Chicago Press}}</ref> and that 89% of the population lived in the cities.

They grew barley, [[chickpea]]s, [[lentil]]s, wheat, [[Date (fruit)|dates]], [[onion]]s, [[garlic]], [[lettuce]], [[leek]]s and [[Mustard plant|mustard]]. Sumerians caught many fish and hunted [[fowl]] and [[gazelle]].<ref>{{cite book|title=The fine art of food | first=Reay |last=Tannahill | publisher=Folio Society| year=1968|location=London|isbn=0850670063}}{{Page needed|date=March 2012}}</ref>

Sumerian agriculture depended heavily on [[irrigation]]. The irrigation was accomplished by the use of ''[[shaduf]]'', [[canal]]s, [[Channel (geography)|channels]], [[dyke (construction)|dykes]], [[weir]]s, and [[reservoirs]]. The frequent violent floods of the [[Tigris]], and less so, of the [[Euphrates]], meant that canals required frequent repair and continual removal of [[silt]], and survey markers and boundary stones needed to be continually replaced. The government required individuals to work on the canals in a [[corvée]], although the rich were able to exempt themselves.

As is known from the "''[[Sumerian Farmer's Almanac]]''", after the flood season and after the [[Spring equinox (northern hemisphere)|Spring equinox]] and the ''[[Akitu]]'' or New Year Festival, using the canals, farmers would flood their fields and then drain the water. Next they made oxen stomp the ground and kill weeds. They then dragged the fields with [[pickaxe]]s. After drying, they plowed, [[harrow (tool)|harrowed]], and [[rake (tool)|raked]] the ground three times, and pulverized it with a [[mattock]], before planting seed. Unfortunately, the high evaporation rate resulted in a gradual increase in the salinity of the fields. By the Ur III period, farmers had switched from wheat to the more salt-tolerant barley as their principal crop.

Sumerians harvested during the [[spring (season)|spring]] in three-person teams consisting of a [[reaper]], a [[Reaper-binder|binder]], and a sheaf handler.<ref>Melvin Kranzberg, Joseph Gies. By the sweat of thy brow: Work in the Western world. Putnam, 1975.</ref> The farmers would use [[threshing]] wagons, driven by oxen, to separate the cereal heads from the [[stalk (botany)|stalks]] and then use threshing sleds to disengage the grain. They then [[winnowing|winnowed]] the grain/chaff mixture.

The Sumerians were great artists. Sumerian artefacts show great detail and ornamentation, with fine semi-precious stones imported from other lands, such as [[lapis lazuli]], [[marble]], and [[diorite]], and precious metals like hammered gold, incorporated into the design. Since stone was rare it was reserved for sculpture. The most widespread material in Sumer was clay, as a result many Sumerian objects are made of clay. Metals such as gold, silver, copper, and bronze, along with shells and gemstones, were used for the finest sculptures and inlays. Small stones of all kinds, including more precious stones such as lapis lazuli, alabaster, and serpentine, were used for [[cylinder seal]]s.

Some of the most famous masterpieces are the [[Lyres of Ur]], which are considered to be the world's oldest surviving [[stringed instrument]]s. They were discovered by [[Leonard Woolley]] when the [[Royal Cemetery of Ur]] was excavated between 1922 and 1934.

===Architecture===
{{Main|Sumerian architecture|Ziggurat|Mudhif}}
{{See also|Clay nail}}
[[File:Ancient ziggurat at Ali Air Base Iraq 2005.jpg|thumb|upright=1.4|The ''[[Great Ziggurat of Ur]]'' ([[Dhi Qar Governorate]], Iraq), built during the [[Third Dynasty of Ur]] (c. 2100 BC), dedicated to the moon god [[Sin (mythology)|Nanna]]]]
The Tigris-Euphrates plain lacked minerals and trees. Sumerian structures were made of plano-convex mudbrick, not fixed with [[Mortar (masonry)|mortar]] or [[cement]]. Mud-brick buildings eventually deteriorate, so they were periodically destroyed, leveled, and rebuilt on the same spot. This constant rebuilding gradually raised the level of cities, which thus came to be elevated above the surrounding plain. The resultant hills, known as [[Tell (archaeology)|tells]], are found throughout the ancient Near East.

According to [[Archibald Sayce]], the primitive [[pictogram]]s of the early Sumerian (i.e. Uruk) era suggest that "Stone was scarce, but was already cut into blocks and seals. Brick was the ordinary building material, and with it cities, forts, temples and houses were constructed. The city was provided with towers and stood on an artificial platform; the house also had a tower-like appearance. It was provided with a door which turned on a hinge, and could be opened with a sort of key; the city gate was on a larger scale, and seems to have been double. The foundation stones—or rather bricks—of a house were consecrated by certain objects that were deposited under them."<ref name="Sayce">{{cite book |last=Sayce (Reverend) |first=A. H. |author-link=Archibald Sayce |url=https://archive.org/stream/archaeologyofcun00sayc/archaeologyofcun00sayc_djvu.txt |title=The Archaeology of the Cuneiform Inscriptions |publisher=Society for Promoting Christian Knowledge |year=1908 |edition=2nd revised |location=London, England; Brighton, England; New York |pages=98–100}}</ref>

The most impressive and famous of Sumerian buildings are the ziggurats, large layered platforms that supported temples. Sumerian cylinder seals also depict houses built from reeds not unlike those built by the [[Marsh Arabs]] of Southern Iraq until as recently as 400 CE. The Sumerians also developed the [[arch]], which enabled them to develop a strong type of dome. They built this by constructing and linking several arches. Sumerian temples and palaces made use of more advanced materials and techniques, such as [[buttress]]es, [[Alcove (architecture)|recesses]], half [[column]]s, and [[clay nail]]s.

===Mathematics===
{{Main|Babylonian mathematics}}

The Sumerians developed a complex system of [[metrology]] c. 4000 BC. This advanced metrology resulted in the creation of arithmetic, geometry, and algebra. From c. 2600 BC onwards, the Sumerians wrote [[multiplication table]]s on clay tablets and dealt with [[geometrical]] exercises and [[Division (mathematics)|division]] problems. The earliest traces of the [[Babylonian numerals]] also date back to this period.<ref>Duncan J. Melville (2003).

===Economy and trade===
{{main|Economy of Sumer}}

[[File:Bill of sale Louvre AO3765.jpg|thumb|Bill of sale of a male slave and a building in [[Shuruppak]], Sumerian tablet, c. 2600 BC]]
Discoveries of [[obsidian]] from far-away locations in [[Anatolia]] and lapis lazuli from [[Badakhshan]] in northeastern [[Afghanistan]], beads from Dilmun (modern [[Bahrain]]), and several seals inscribed with the [[Indus Valley civilisation|Indus Valley]] [[Indus script|script]] suggest a remarkably wide-ranging network of ancient trade centered on the [[Persian Gulf]]. For example, [[Imports to Ur]] came from many parts of the world. In particular, the metals of all types had to be imported.

The ''Epic of Gilgamesh'' refers to trade with far lands for goods, such as wood, that were scarce in Mesopotamia. In particular, [[Cedrus libani|cedar]] from [[Lebanon]] was prized. The finding of resin in the tomb of Queen [[Puabi]] at Ur, indicates it was traded from as far away as [[Mozambique]].

The Sumerians used slaves, although they were not a major part of the economy. Slave women worked as [[weaving|weavers]], pressers, [[miller]]s, and [[porter (carrying)|porters]].{{Citation needed|date=September 2019}}

Sumerian potters decorated pots with [[cedar oil]] [[paint]]s. The potters used a [[bow drill]] to produce the fire needed for baking the pottery. Sumerian [[masonry|masons]] and [[jewelry|jewelers]] knew and made use of [[alabaster]] ([[calcite]]), [[ivory]], [[iron]], [[gold]], [[silver]], [[carnelian]], and lapis lazuli.<ref>Marian H. Feldman, ''Diplomacy by design: Luxury arts and an "international style" in the ancient Near East, 1400–1200 BC'', (Chicago, Illinois: University Press, 2006), pp.&nbsp;120–121.</ref>

[[Gudea]], the ruler of the Neo-Sumerian Empire at Lagash, is recorded as having imported "translucent carnelian" from [[Meluhha]], generally thought to be the Indus Valley area.<ref name="JMI"/> Various inscriptions also mention the presence of Meluhha traders and interpreters in Mesopotamia.<ref name="JMI"/> About twenty seals have been found from the Akkadian and Ur III sites, that have connections with Harappa and often use Harappan symbols or writing.<ref name="JMI"/>

The Indus Valley Civilization only flourished in its most developed form between 2400 and 1800 BC, but at the time of these exchanges, it was a much larger entity than the Mesopotamian civilization, covering an area of 1.2 million square kilometers with thousands of settlements, compared to an area of only about 65.000 square kilometers for the occupied area of Mesopotamia, while the largest cities were comparable in size at about 30–40,000 inhabitants.<ref>{{cite book |last1=Cotterell |first1=Arthur |title=Asia: A Concise History |date=2011 |publisher=John Wiley & Sons |isbn=978-0-470-82959-2 |page=42 |url=https://books.google.com/books?id=9_vVTWXK5kQC&pg=PT42 }}</ref>

====Money and credit====
Large institutions kept their accounts in barley and [[silver]], often with a fixed rate between them. The obligations, loans and prices in general were usually denominated in one of them. Many transactions involved debt, for example goods consigned to merchants by temple and beer advanced by "ale women".<ref name = debt>{{cite book |title= Debt and Economic Renewal in the Ancient Near East|editor=Michael Hudson and Marc Van De Mieroop|last= Hudson|first= Michael|year= 1998|publisher= CDL|location= Bethesda, Maryland|isbn= 978-1-883053-71-0|pages= 23–35}}</ref>

Commercial credit and agricultural consumer loans were the main types of loans. The trade credit was usually extended by temples in order to finance trade expeditions and was nominated in silver. The interest rate was set at 1/60 a month (one [[shekel]] per [[mina (unit)|mina]]) some time before 2000 BC and it remained at that level for about two thousand years.<ref name = debt/>
Rural loans commonly arose as a result of unpaid obligations due to an institution (such as a temple), in this case the arrears were considered to be lent to the debtor.<ref name = debt2>{{cite book |title= Debt and Economic Renewal in the Ancient Near East|editor=Michael Hudson and Marc Van De Mieroop|last= Van De Mieroop|first= Marc|year= 1998|publisher= CDL|location= Bethesda, Maryland|isbn= 978-1-883053-71-0|page= 63}}</ref> They were denominated in barley or other crops and the interest rate was typically much higher than for commercial loans and could amount to 1/3 to 1/2 of the loan principal.<ref name = debt/>

Periodically, rulers signed "clean slate" decrees that cancelled all the rural (but not commercial) debt and allowed bondservants to return to their homes. Customarily, rulers did it at the beginning of the first full year of their reign, but they could also be proclaimed at times of military conflict or crop failure. The first known ones were made by [[Enmetena]] and [[Urukagina]] of Lagash in 2400–2350 BC. According to Hudson, the purpose of these decrees was to prevent debts mounting to a degree that they threatened the fighting force, which could happen if peasants lost their subsistence land or became bondservants due to inability to repay their debt.<ref name = debt/>

The almost constant wars among the Sumerian city-states for 2000 years helped to develop the military technology and techniques of Sumer to a high level.<ref>Roux, Georges (1992), "Ancient Iraq" (Penguin).</ref> The first war recorded in any detail was between Lagash and Umma in c. 2450 BC on a stele called the [[Stele of the Vultures]]. It shows the king of Lagash leading a Sumerian army consisting mostly of [[infantry]]. The infantry carried [[spear]]s, wore [[copper]] [[helmet]]s, and carried rectangular [[shield]]s. The spearmen are shown arranged in what resembles the [[phalanx formation]], which requires training and discipline; this implies that the Sumerians may have used professional soldiers.<ref>Winter, Irene J. (1985). "After the Battle is Over: The 'Stele of the Vultures' and the Beginning of Historical Narrative in the Art of the Ancient Near East". In Kessler, Herbert L.; Simpson, Marianna Shreve. Pictorial Narrative in Antiquity and the Middle Ages. Center for Advanced Study in the Visual Arts, Symposium Series IV 16.

The Sumerian military used carts harnessed to [[onager]]s. These early [[chariot]]s functioned less effectively in combat than did later designs, and some have suggested that these chariots served primarily as transports, though the crew carried battle-axes and [[lance]]s. The Sumerian chariot comprised a four or two-[[wheel]]ed device manned by a crew of two and harnessed to four onagers. The cart was composed of a [[basket|woven basket]] and the wheels had a solid three-piece design.

Sumerian cities were surrounded by [[defensive wall]]s. The Sumerians engaged in [[siege]] warfare between their cities, but the mudbrick walls were able to deter some foes.

===Technology===
Examples of Sumerian technology include: the wheel, cuneiform script, [[arithmetic]] and [[geometry]], [[irrigation]] systems, Sumerian boats, [[lunisolar calendar]], [[bronze]], [[leather]], [[saw]]s, [[chisel]]s, [[hammer]]s, [[brace (tool)|braces]], [[Bit (horse)|bits]], [[nail (engineering)|nails]], [[pin]]s, [[jewelry ring|rings]], [[hoe (tool)|hoes]], [[axe]]s, [[knife|knives]], [[lance]]points, [[arrow (weapon)|arrowheads]], [[sword]]s, [[adhesive|glue]], [[dagger]]s, [[waterskin]]s, bags, [[horse harness|harnesses]], [[armor]], [[quiver]]s, [[war chariot]]s, [[scabbard]]s, [[boot]]s, [[sandal (footwear)|sandals]], [[harpoon]]s and beer.
The Sumerians had three main types of boats:
* clinker-built sailboats stitched together with hair, featuring [[bitumen]] waterproofing
* skin boats constructed from animal skins and reeds
* wooden-oared ships, sometimes pulled upstream by people and animals walking along the nearby banks

Evidence of wheeled vehicles appeared in the mid-4th millennium BC, near-simultaneously in Mesopotamia, the Northern Caucasus ([[Maykop culture]]) and Central Europe. The wheel initially took the form of the potter's wheel. The new concept led to wheeled [[vehicle]]s and mill wheels. The Sumerians' cuneiform script is the oldest (or second oldest after the [[Egyptian hieroglyphs]]) which has been deciphered (the status of even older inscriptions such as the [[Jiahu symbols]] and [[Tărtăria tablets|Tartaria tablets]] is controversial). The Sumerians were among the first astronomers, mapping the stars into sets of constellations, many of which survived in the [[zodiac]] and were also recognized by the ancient Greeks.<ref name="Thompson">{{cite web |author=Thompson |first=Gary |title=History of Constellation and Star Names |url=http://members.optusnet.com.au/~gtosiris/page11-4.html |url-status=dead |archive-url=https://web.archive.org/web/20120821025411/http://members.optusnet.com.au/~gtosiris/page11-4.html |archive-date=2012-08-21 |access-date=2012-03-29 |publisher=Members.optusnet.com.au}}</ref>{{Unreliable source?|failed=y|date=March 2012}} They were also aware of the [[classical planet|five planets]] that are easily visible to the naked eye.<ref name="SumerFAQ2">{{cite web|url=http://www.sumerian.org/sumerfaq.htm#s39 |title=Sumerian Questions and Answers |publisher=Sumerian.org |access-date=2012-03-29}}</ref>

They invented and developed arithmetic by using several different number systems including a [[mixed radix]] system with an alternating base 10 and base 6. This [[sexagesimal]] system became the standard number system in Sumer and Babylonia. They may have invented military formations and introduced the basic divisions between [[infantry]], [[cavalry]], and [[archers]]. They developed the first known codified legal and administrative systems, complete with courts, jails, and government records.

The first true city-states arose in Sumer, roughly contemporaneously with similar entities in what are now [[Syria]] and [[Lebanon]]. Several centuries after the invention of cuneiform, the use of writing expanded beyond debt/payment certificates and inventory lists to be applied for the first time, about 2600 BC, to messages and mail delivery, history, legend, mathematics, astronomical records, and other pursuits. Conjointly with the spread of writing, the first formal schools were established, usually under the auspices of a city-state's primary temple.
