Uruk (Cuneiform: 𒌷𒀔,URU UNUG; Sumerian: Unug; Akkadian: Uruk; Aramaic/Hebrew: אֶרֶךְ Erech; Ancient Greek: Ὀρχόη Orchoē, Ὠρύγεια Ōrugeia; Arabic: وركاء, Warkā') was an ancient city of Sumer and later Babylonia, situated east of the present bed of the Euphrates river, on the ancient dry former channel of the Euphrates River, some 30 km east of modern As-Samawah, Al-Muthannā, Iraq.
Uruk gave its name to the Uruk period, the protohistoric Chalcolithic to Early Bronze Age period in the history of Mesopotamia spanning c. 4000 to 3100 BC, succeeded by the Jemdet Nasr period of Sumer proper. Uruk played a leading role in the early urbanization of Sumer in the mid 4th millennium BC. At its height c 2900 BC, Uruk probably had 50,000–80,000 residents living in 6 km2 of walled area; making it the largest city in the world at the time. The legendary king Gilgamesh, according to the chronology presented in the Sumerian king list, ruled Uruk in the 27th century BC. The city lost its prime importance around 2000 BC, in the context of the struggle of Babylonia with Elam, but it remained inhabited throughout the Seleucid and Parthian periods until it was finally abandoned shortly before or after the Islamic conquest.
The site of Uruk was discovered in 1849 by William Kennett Loftus who led the first excavations from 1850 to 1854. The Arabic name of Babylonia, al-ʿIrāq, is thought to be derived from the name Uruk, via Aramaic (Erech) and possibly Middle Persian (Erāq) transmission.

In myth and literature, Uruk was famous as the capital city of Gilgamesh, hero of the Epic of Gilgamesh. It is also believed Uruk is the biblical (Genesis 10:10) Erech, the second city founded by Nimrod in Shinar.
In addition to being one of the first cities, Uruk was the main force of urbanization during the Uruk period (4000–3200 BC). This period of 800 years saw a shift from small, agricultural villages to a larger urban center with a full-time bureaucracy, military, and stratified society. Although other settlements coexisted with Uruk, they were generally about 10 hectares while Uruk was significantly larger and more complex. The Uruk period culture exported by Sumerian traders and colonists had an effect on all surrounding peoples, who gradually evolved their own comparable, competing economies and cultures. Ultimately, Uruk could not maintain long-distance control over colonies such as Tell Brak by military force.
Geographic factors underpin Uruk's unprecedented growth. The city was located in the southern part of Mesopotamia, an ancient site of civilization, on the Euphrates rivers. Through the gradual and eventual domestication of native grains from the Zagros foothills and extensive irrigation techniques, the area supported a vast variety of edible vegetation. This domestication of grain and its proximity to rivers enabled Uruk's growth into the largest Sumerian settlement, in both population and area, with relative ease.
Uruk's agricultural surplus and large population base facilitated processes such as trade, specialization of crafts and the evolution of writing. Evidence from excavations such as extensive pottery and the earliest known tablets of writing support these events. Excavation of Uruk is highly complex because older buildings were recycled into newer ones, thus blurring the layers of different historic periods. The topmost layer most likely originated in the Jemdet Nasr period (3100–2900 BC) and is built on structures from earlier periods dating back to the Ubaid period.
According to the Sumerian king list, Uruk was founded by the king Enmerkar. Though the king-list mentions a king of Eanna before him, the epic Enmerkar and the Lord of Aratta relates that Enmerkar constructed the House of Heaven (Sumerian: e2-anna; Cuneiform: 𒂍𒀭 E2.AN) for the goddess Inanna in the Eanna District of Uruk. In the Epic of Gilgamesh, Gilgamesh builds the city wall around Uruk and is king of the city.
Uruk went through several phases of growth, from the Early Uruk period (4000–3500 BC) to the Late Uruk period (3500–3100 BC). The city was formed when two smaller Ubaid settlements merged. The temple complexes at their cores became the Eanna District and the Anu District dedicated to Inanna and Anu, respectively. The Anu District was originally called 'Kullaba' (Kulab or Unug-Kulaba) prior to merging with the Eanna District. Kullaba dates to the Eridu period when it was one of the oldest and most important cities of Sumer. There are different interpretations about the purposes of the temples. However, it is generally believed they were a unifying feature of the city. It also seems clear that temples served both an important religious function and state function. The surviving temple archive of the Neo-Babylonian period documents the social function of the temple as a redistribution center.
The Eanna District was composed of several buildings with spaces for workshops, and it was walled off from the city. By contrast, the Anu District was built on a terrace with a temple at the top. It is clear Eanna was dedicated to Inanna from the earliest Uruk period throughout the history of the city. The rest of the city was composed of typical courtyard houses, grouped by profession of the occupants, in districts around Eanna and Anu. Uruk was extremely well penetrated by a canal system that has been described as, "Venice in the desert." This canal system flowed throughout the city connecting it with the maritime trade on the ancient Euphrates River as well as the surrounding agricultural belt.
The original city of Uruk was situated southwest of the ancient Euphrates River, now dry. Currently, the site of Warka is northeast of the modern Euphrates river. The change in position was caused by a shift in the Euphrates at some point in history, and may have contributed to the decline of Uruk.
Historic periods of Uruk
Archeologists have discovered multiple cities of Uruk built atop each other in chronological order.
- Uruk XVIII Eridu period (c 5000 BC); the founding of Uruk
- Uruk XVIII-XVI Late Ubaid period (4800–4200 BC)
- Uruk XVI-X Early Uruk period (4000–3800 BC)
- Uruk IX-VI Middle Uruk period (3800–3400 BC)
- Uruk V-IV Late Uruk period (3400–3100 BC); The earliest monumental temples of Eanna District are built
- Uruk III Jemdet Nasr period (3100–2900 BC); The 9 km city wall is built
- Uruk II
- Uruk I
The Eanna district is historically significant as both writing and monumental public architecture emerge here during Uruk periods VI-IV. The combination of these two developments places Eanna as arguably the first true city and civilization in human history. Eanna during period IVa contains the earliest examples of cuneiform writing and therefore the earliest writing in history. Although some of these cuneiform tablets have been deciphered, difficulty with site excavations has obscured the purpose and sometimes even the structure of many buildings.
The first building of Eanna, Stone-Cone Temple (Mosaic Temple), was built in period VI over a preexisting Ubaid temple and is enclosed by a limestone wall with an elaborate system of buttresses. The Stone-Cone Temple, named for the mosaic of colored stone cones driven into the adobe brick façade, may be the earliest water cult in Mesopotamia. It was ritually demolished in Uruk IVb period and its contents interred in the Riemchen Building.
In the following period, Uruk V, about 100 m east of the Stone-Cone Temple the Limestone Temple was built on a 2 m high rammed-earth podium over a pre-existing Ubaid temple, which like the Stone-Cone Temple represents a continuation of Ubaid culture. However, the Limestone Temple was unprecedented for its size and use of stone, a clear departure from traditional Ubaid architecture. The stone was quarried from an outcrop at Umayyad about 60 km east of Uruk. It is unclear if the entire temple or just the foundation was built of this limestone. The Limestone temple is probably the first Inanna temple, but it is impossible to know with certainty. Like the Stone-Cone temple the Limestone temple was also covered in cone mosaics. Both of these temples were rectangles with their corners aligned to the cardinal directions, a central hall flanked along the long axis flanked by two smaller halls, and buttressed façades; the prototype of all future Mesopotamian temple architectural typology.
Between these two monumental structures a complex of buildings (called A-C, E-K, Riemchen, Cone-Mosaic), courts, and walls was built during Eanna IVb. These buildings were built during a time of great expansion in Uruk as the city grew to 250 hectares and established long distance trade, and are a continuation of architecture from the previous period. The Riemchen Building, named for the brick shape called Riemchen by the Germans, is a memorial with a ritual fire kept burning in the center for the Stone-Cone Temple after it was destroyed. For this reason, Uruk IV period represents a reorientation of belief and culture. The facade of this memorial may have been covered in geometric and figural murals. The Riemchen bricks first used in this temple were used to construct all buildings of Uruk IV period Eanna. The use of colored cones as a façade treatment was greatly developed as well, perhaps used to greatest effect in the Cone-Mosaic Temple. Composed of three parts: Temple N, the Round Pillar Hall, and the Cone-Mosaic Courtyard, this temple was the most monumental structure of Eanna at the time. They were all ritually destroyed and the entire Eanna district was rebuilt in period IVa at an even grander scale.
During Eanna IVa, the Limestone Temple was demolished and the Red Temple built on its foundations. The accumulated debris of the Uruk IVb buildings were formed into a terrace, the L-Shaped Terrace, on which Buildings C, D, M, Great Hall, and Pillar Hall were built. Building E was initially thought to be a palace, but later proven to be a communal building. Also in period IV, the Great Court, a sunken courtyard surrounded by two tiers of benches covered in cone mosaic, was built. A small aqueduct drains into the Great Courtyard, which may have irrigated a garden at one time. The impressive buildings of this period were built as Uruk reached its zenith and expanded to 600 hectares. All the buildings of Eanna IVa were destroyed sometime in Uruk III, for unclear reasons.
The architecture of Eanna in period III was very different from what had preceded it. The complex of monumental temples was replaced with baths around the Great Courtyard and the labyrinthine Rammed-Earth Building. This period corresponds to Early Dynastic Sumer c 2900 BC, a time of great social upheaval when the dominance of Uruk was eclipsed by competing city-states. The fortress-like architecture of this time is a reflection of that turmoil. The temple of Inanna continued functioning during this time in a new form and under a new name, 'The House of Inanna in Uruk' (Sumerian: e2-dinanna unuki-ga). The location of this structure is currently unknown.
The great Anu district is older than the Eanna district; however, few remains of writing have been found here. Unlike the Eanna district, the Anu district consists of a single massive terrace, the Anu Ziggurat, dedicated to the Sumerian sky god, An. Sometime in the Uruk III period the massive White Temple, was built atop of the ziggurat, and under the northwest edge of the ziggurat an Uruk VI period structure, the Stone Temple, has been discovered.
The Stone Temple was built of limestone and bitumen on a podium of rammed earth and plastered with lime mortar. The podium itself was built over a woven reed mat called giparu a word which originally referred a reed mat used ritually as a nuptial bed, but took on the meaning as the source of abundance which radiated upward into the structure. The structure of the Stone Temple further develops some mythological concepts from Enuma Elish, perhaps involving libation rites as indicated from the channels, tanks, and vessels found there. The structure was ritually destroyed, covered with alternating layers of clay and stone, then excavated filled with mortar sometime later.
The Anu Ziggurat began with a massive mound topped by a cella during the Uruk period c 4000 BC and was expanded through 14 phases of construction, labeled L to A3 (L is sometimes called X). Interestingly, the earliest phase, used typology similar to PPNA cultures in Anatolia; a single chamber cella with a terazzo floor beneath which, bucrania were found. In phase E, corresponding to Uruk III period c 3000 BC, the White Temple was built. The White Temple was clearly designed to be seen from a great distance across the plain of Sumer as it was elevated 21 m and covered in gypsum plaster which reflected sunlight like a mirror. For this reason, it is believed the White Temple is a symbol of Uruk's political power at the time. In addition to this temple, the Anu Ziggurat also had a monumental limestone paved staircase used in religious processions. A trough running parallel to the staircase was used to drain the ziggurat.
Uruk into late Antiquity
Although it had been a thriving city in Early Dynastic Sumer, especially Early Dynastic II, Uruk was ultimately annexed to the Akkadian Empire and went into decline. Later, in the Neo-Sumerian period, Uruk enjoyed revival as a major economic and cultural center under the sovereignty of Ur. The Eanna District was restored as part of an ambitious building program, which included a new temple for Inanna. This temple included a ziggurat, the 'House of the Universe' (Cuneiform: E2.SAR.A) to the northeast of the Uruk period Eanna ruins. The ziggurat is also cited as Ur-Nammu Ziggurat for its builder Ur-Nammu. Following the collapse of Ur (c 2000 BC), Uruk went into a steep decline until about 850 BC when the Neo-Assyrian Empire annexed it as a provincial capital. Under the Neo-Assyrians and Neo-Babylonians, Uruk regained much of its former glory. By 250 BC, a new temple complex the 'Head Temple' (Akkadian: Bīt Reš) was added to northeast of the Uruk period Anu district. The Bīt Reš along with the Esagila was one of the two main centers of Neo-Babylonian astronomy. All of the temples and canals were restored again under Nabopolassar. During this era, Uruk was divided into five main districts: the Adad Temple, Royal Orchard, Ištar Gate, Lugalirra Temple, and Šamaš Gate districts.
Uruk, now known as Orchoë to the Greeks, continued to thrive under the Seleucid Empire. During this period, Uruk was a city of 300 hectares. In 200 BC, the 'Great Sanctuary' (Cuneiform: E2.IRI12.GAL, Sumerian: eš-gal) of Ishtar was added between the Anu and Eanna districts. When the Seleucids lost Mesopotamia to the Parthians in 141 BC, Uruk again entered a period of decline from which it never recovered. The decline of Uruk may have been in part caused by a shift in the Euphrates River. By 300 AD, Uruk was mostly abandoned, and by c 700 AD it was completely abandoned.
"In Uruk, in southern Mesopotamia, Sumerian civilization seems to have reached its creative peak. This is pointed out repeatedly in the references to this city in religious and, especially, in literary texts, including those of mythological content; the historical tradition as preserved in the Sumerian king-list confirms it. From Uruk the center of political gravity seems to have moved to Ur."
Uruk played a very important part in the political history of Sumer. Starting from the Early Uruk period, exercising hegemony over nearby settlements. At this time (c 3800 BC), there were two centers of 20 hectares, Uruk in the south and Nippur in the north surrounded by much smaller 10 hectare settlements. Later, in the Late Uruk period, its sphere of influence extended over all Sumer and beyond to external colonies in upper Mesopotamia and Syria. Uruk was prominent in the national struggles of the Sumerians against the Elamites up to 2004 BC, in which it suffered severely; recollections of some of these conflicts are embodied in the Gilgamesh epic, in the literary and courtly form that has come down to us.
The recorded chronology of rulers over Uruk includes both mythological and historic figures in five dynasties. As in the rest of Sumer, power moved progressively from the temple to the palace. Rulers from the Early Dynastic period exercised control over Uruk and at times over all Sumer. In myth, kingship was lowered from heaven to Eridu then passed successively through five cites until the deluge which ended the Uruk period. Afterwards, kingship passed to Kish at the beginning of the Early Dynastic period, which corresponds to the beginning of the Early Bronze Age in Sumer. In the Early Dynastic I period (2900–2800 BC), Uruk was in theory under the control of Kish. This period is sometimes called the Golden Age. During the Early Dynastic II period (2800–2600 BC), Uruk was again the dominant city exercising control of Sumer. This period is the time of the First Dynasty of Uruk sometimes called the Heroic Age. However, by the Early Dynastic IIIa period (2600–2500 BC) Uruk had lost sovereignty, this time to Ur. This period, corresponding to the Early Bronze Age III, is the end of the First Dynasty of Uruk. In the Early Dynastic IIIb period (2500–2334 BC), also called the Pre-Sargonic period (referring to Sargon of Akkad), Uruk continued to be ruled by Ur.
Early dynastic, Akkadian, and Neo-Sumerian rulers of Uruk
- 1st Dynasty of Uruk
- Mesh-ki-ang-gasher; son of the god Utu and founder of Uruk who received kingship from the 1st Dynasty of Kish
- Dumuzid, the Fisherman
- Ur-Nungal, Udul-kalama, La-ba'shum, En-nun-tarah-ana, Mesh-he, Melem-ana, Lugal-kitun; little is known of these rulers the final ruler was overthrown by Mesannepada of Ur, thus ending the first dynasty
- 2nd Dynasty of Uruk
- Enshakushanna; re-established kingship over Sumer, however following his death kingship passed to Eannatum of Lagash
- Lugal-kinishe-dudu, Argandea, Lugal-ure; served as ensi of Uruk under the 1st Dynasty of Lagash
- 3rd Dynasty of Uruk
- Lugalzagesi (2296–2271 BC); originally of Umma, he made Uruk his new capital after conquering all Sumer
- 4th Dynasty of Uruk
- Ur-ningin, Ur-gigir, Kuda, Puzur-ili; served as ensi of Uruk under the Akkadian Empire
- 5th Dynasty of Uruk
- Utu-hengal (2119–2112 BC); an ensi of Uruk who overthrew the Gutians and briefly ruled Sumer until he was defeated by Ur-Nammu of Ur, thus ending the final dynasty of Uruk
Uruk continued as principality of Ur, Babylon, and later Achaemenid, Seleucid, and Parthian Empires. It enjoyed brief periods of independence during the Isin-Larsa period, under kings such as (possibly) Ikūn-pî-Ištar (ca. 1800 BC), Sîn-kāšid, his son Sîn-irībam, his son Sîn-gāmil, Ilum-gāmil, brother of Sîn-gāmil, Etēia, Anam, ÌR-ne-ne, who was defeated by Rīm-Sîn I of Larsa in his year 14 (ca. 1740 BC), Rīm-Anum and Nabi-ilīšu. The city was finally destroyed by the Arab invasion of Mesopotamia and abandoned c 700 AD.
Uruk has the first monumental constructions in architectural history. Much of Near Eastern architecture can trace it roots to these prototypical buildings. The structures of Uruk are cited by two different naming conventions, one in German from the initial expedition, and the English translation of the same. The stratigraphy of the site is complex and as such much of the dating is disputed. In general, the structures follow the two main typologies of Sumerian architecture, Tripartite with 3 parallel halls and T-Shaped also with three halls, but the central one extends into two perpendicular bays at one end. The following table summarizes the significant architecture of the Eanna and Anu Districts. Temple N, Cone-Mosaic Courtyard, and Round Pillar Hall are often referred to as a single structure; the Cone-Mosaic Temple.

It is clear Eanna was dedicated to Inanna symbolized by Venus from the Uruk period. At that time, she was worshipped in four aspects as Inanna of the netherworld (Sumerian: dinanna-kur), Inanna of the morning (Sumerian: dinanna-hud2), Inanna of the evening (Sumerian: dinanna-sig), and Inanna (Sumerian: dinanna-NUN). The names of four temples in Uruk at this time are known, but it is impossible to match them with either a specific structure and in some cases a deity.
- sanctuary of Inanna (Sumerian: eš-dinanna)
- sanctuary of Inanna of the evening (Sumerian: eš-dinanna-sig)
- temple of heaven (Sumerian: e2-an)
- temple of heaven and netherworld (Sumerian: e2-an-ki)
The site, which lies about 50 miles northwest of ancient Ur, is one of the largest in the region at around 5.5 square kilometers in area. The maximum extent is 3 kilometers north/south and 2.5 kilometers east/west. There are three major tells within the site, the Eanna district, Bit Resh (Kullaba), and Irigal.
The location of Uruk was first scouted by William Loftus in 1849. He excavated there in 1850 and 1854. By Loftus' own account, he admits that the first excavations were superficial at best, as his financiers forced him to deliver large museum artifacts at a minimal cost. Warka was also scouted by archaeologist Walter Andrae in 1902.
From 1912 to 1913, Julius Jordan and his team from the German Oriental Society discovered the temple of Ishtar, one of four known temples located at the site. The temples at Uruk were quite remarkable as they were constructed with brick and adorned with colorful mosaics. Jordan also discovered part of the city wall. It was later discovered that this 40 to 50-foot (15 m) high brick wall, probably utilized as a defense mechanism, totally encompassed the city at a length of 9 km (5.6 mi). Utilizing sedimentary strata dating techniques, this wall is estimated to have been erected around 3000 BC. The GOS returned to Uruk in 1928 and excavated until 1939, when World War II intervened. The team was led by Jordan until 1931, then by A. Nöldeke, Ernst Heinrich, and H. J. Lenzen.
The German excavations resumed after the war and were under the direction of Heinrich Lenzen from 1953 to 1967. He was followed in 1968 by J. Schmidt, and in 1978 by R.M. Boehmer. In total, the German archaeologists spent 39 seasons working at Uruk. The results are documented in two series of reports:
- Ausgrabungen der Deutschen Forschungsgemeinschaft in Uruk (ADFU), 17 volumes, 1912–2001 (titles listed at the German Archaeological Institute )
- Ausgrabungen in Uruk-Warka, Endberichte (AUWE), 25 volumes, 1987–2007 (titles listed at the German Archaeological Institute )
Most recently, from 2001 to 2002, the German Archaeological Institute team led by Margarite Van Ess, with Joerg Fassbinder and Helmut Becker, conducted a partial magnetometer survey in Uruk. In addition to the geophysical survey, core samples and aerial photographs were taken. This was followed up with high-resolution satellite imagery in 2005.
Clay tablets have been found at Uruk with Sumerian and pictorial inscriptions that are thought to be some of the earliest recorded writing, dating to approximately 3300 BC. These tablets were deciphered and include the famous Sumerian King List, a record of kings of the Sumerian civilization. There was an even larger cache of legal and scholarly tablets of the Seleucid period, that have been published by Adam Falkenstein and other German epigraphists.
The Mask of Warka, also known as the 'Lady of Uruk' and the 'Sumerian Mona Lisa', dating from 3100 BC, is one of the earliest representations of the human face. The carved marble female face is probably a depiction of Inanna. It is approximately 20 cm tall, and may have been incorporated into a larger cult image. The mask was looted from the National Museum of Iraq during the fall of Baghdad in April 2003. It was recovered in September 2003 and returned to the museum.

- While earlier scholars such as Jerome (4th century) had identified Erech with the Syrian city of Edessa (now within Turkey), the modern consensus is that it refers to the Sumerian city-state of Uruk in south Mesopotamia. See Warwick Ball, 2001, Rome in the East: the transformation of an empire, p. 89. Ball further speculates that the earlier traditions connecting Edessa (Orhai) with Erech might have arisen because the ancient Uruk was possibly 'transferred' to the more northerly location in the reign of Nabonidus of Babylon, 6th century BC.
