Uruk

• 1. Introduction

  ›

  Uruk was once the largest city on earth. Around 3100 BC, somewhere between 40,000 and 90,000 people lived within its boundaries and surrounding land, in a region that is now the Muthanna Governorate of Iraq. Today the site is called Warka, and it sits east of the current bed of the Euphrates River, on an ancient, dried channel that once sustained one of the earliest and most consequential experiments in urban life humanity has ever attempted. What made a city in 4th-millennium Mesopotamia grow so large? What institutions, temples, and ideas allowed Uruk to project its influence across an entire region? And what, in the end, brought it to silence by around 700 AD? The answers lie in layers of mud brick, thousands of clay tablets, and a king whose name you already know.

• 2. A City Born from Two

  ›

  Uruk did not spring fully formed from the desert. Two smaller Ubaid-period settlements, Unug and Kullaba, each with their own temple complexes, eventually merged to create the city. The temple of Unug became the Eanna District, dedicated to the goddess Inanna. The temple of Kullaba became the Anu District, built on a raised terrace with a temple at its crown. These two sacred cores gave Uruk a dual identity it would carry for millennia. Between them grew a city of courtyard houses arranged by the profession of their residents, threaded together by a canal system that one scholar described as "Venice in the desert". That canal network connected the city both to maritime trade on the Euphrates and to the agricultural fields that fed its people. The founding of the city is attributed in the Sumerian King List to a king named Enmerkar, who according to legend constructed the House of Heaven, known in Sumerian as e2-anna, for the goddess Inanna in the Eanna District.

• 3. The Uruk Expansion

  ›

  Between roughly 4000 and 3200 BC, an 800-year stretch called the Uruk period, the city drove a transformation across the ancient Near East. Before it, the region was dotted with agricultural villages of around 10 hectares. Uruk was significantly larger and more complex than any of them. It built a full-time bureaucracy, maintained a military, and developed a stratified society in ways that contemporaries could not match. Sumerian traders and colonists carried Uruk-period culture outward, influencing all surrounding peoples and nudging them toward their own competing economies. The reach of Uruk extended not just across Sumer but into upper Mesopotamia and Syria. Ultimately the city could not hold its distant colonies, such as Tell Brak, by military force alone. The limits of early empire were not a matter of will but of logistics and distance.

• 4. Writing and the Eanna District

  ›

  Eanna in period IVa contains the earliest known examples of writing. Around 190 tablets from the Uruk V period, dating to roughly 3500 BC, are numerical or impressed tablets, simple counting records. By the Uruk IV period around 3300 BC there were 1,776 tablets, and the Uruk III period, also called the Jemdet Nasr period, yielded 3,094 more. Among the most remarkable finds is the oldest known writing to feature a person's name. Several tablets from Uruk record a figure named Kushim, who appears to have served as an accountant tracking barley transactions: 29,086 measures of barley over 37 months. Whether Kushim was a single individual or a title remains uncertain, but the tablets are dated to a time before most of civilization had thought to write down a name at all. The last dated cuneiform tablet from Uruk, a piece catalogued as W22340a and described as an astronomical almanac, is dated to 79 or 80 AD, meaning the city produced written records across roughly 3,500 years.

• 5. Temples Built to Outlast Empires

  ›

  The Stone-Cone Temple of the Eanna District, constructed in period VI over a pre-existing Ubaid temple, takes its name from the mosaic of colored stone cones driven into its adobe brick facade. It may be the earliest water cult in Mesopotamia. After it was "destroyed by force" in Uruk period IVb, a memorial called the Riemchen Building was built in its place, with a ritual fire kept burning at its center. The Riemchen bricks, named for the 16 cm by 16 cm brick shape the German excavators called Riemchen, were then used to construct all buildings of the Uruk IV period in Eanna. The Limestone Temple, built in period V on a 2-meter-high rammed-earth podium, used stone quarried from an outcrop at Umayyad about 60 km east of the city. It was unprecedented in both scale and material. Together, the Limestone Temple and the Stone-Cone Temple established the prototype for all future Mesopotamian temple architecture: rectangles with corners aligned to the cardinal directions, a central hall flanked by two smaller halls, and buttressed facades. Much later, during the Seleucid period, the ziggurat of the temple of Anu was rebuilt and became the largest ever built in Mesopotamia.

• 6. The Mask and the Tablets

  ›

  The Mask of Warka, also called the Lady of Uruk and the Sumerian Mona Lisa, dates from 3100 BC and stands approximately 20 cm tall. It is a carved marble female face, almost certainly a depiction of Inanna, and may once have been incorporated into a larger cult image. It is among the earliest representations of the human face ever made. When Iraqi museums were looted during the invasion of Iraq in April 2003, the mask was taken. It was recovered in September 2003 and returned to the Iraq Museum. Uruk's clay tablets tell an equally remarkable story of institutional continuity. Among later finds is a large cache of legal and scholarly tablets from the Neo-Babylonian, Late Babylonian, and Seleucid periods, published by Adam Falkenstein and colleagues at the German Archaeological Institute in Baghdad, including Jan J. A. Djik, Hermann Hunger, and Antoine Cavigneaux. Many of the tablets from Uruk have entered collections at the British Museum, the Yale Babylonian Collection, and the Louvre. The Louvre holds a unique cuneiform tablet in Aramaic known as the Aramaic Uruk incantation.

• 7. Excavating Uruk

  ›

  William Kennett Loftus visited Warka in 1849 and identified the mound as ancient Erech, known in older tradition as the second city of Nimrod. He led the first excavations from 1850 to 1854, though he later admitted the work was superficial because his financiers demanded large museum artifacts at minimal cost. A basalt stela he found was subsequently lost. By 1912, Julius Jordan and a team from the German Oriental Society had begun systematic work, discovering the temple of Ishtar and tracing the city wall, a structure estimated to have been built around 3000 BC, standing 40 to 50 feet high and encircling the entire city at a length of 9 km. Jordan produced a contour map of the site before his team returned in 1928 and excavated until 1939, when World War II intervened. German excavators continued in successive waves under Heinrich Lenzen from 1954 to 1967, then J. Schmidt from 1968, and R. M. Boehmer from 1978. In total, 39 seasons of German fieldwork at Uruk produced two major publication series: 17 volumes of the ADFU covering 1912 to 2001, and 25 volumes of the AUWE published from 1987 to 2007. In 2003, magnetometer scans by a team led by Margarete van Ess detected buried structures in the former bed of the Euphrates that Joerg Fassbinder noted matched ancient Sumerian descriptions of the city, raising the possibility that what the scans revealed could be the tomb of Gilgamesh. Fassbinder was careful to say no solid proof existed, but the scans' correspondence with the Sumerian poem The Death of Gilgamesh drew wide media attention before the Iraq invasion shifted focus. Sediment coring continued into 2024 and 2025, producing a virtual geophysical topology of the entire Uruk area.

• 8. Silence and Abandonment

  ›

  Uruk's long decline was not a single event but a slow unraveling across centuries. After the Akkadian Empire annexed the city, it contracted. Under the Neo-Sumerian period it revived, and the Eanna District was restored with a new temple for Inanna that included a ziggurat called the House of the Universe. After the fall of Ur around 2000 BC, Uruk fell steeply again until the Neo-Assyrian Empire absorbed it as a provincial capital around 850 BC. By 250 BC, under the Seleucid Empire, the city covered 300 hectares and may again have held around 40,000 inhabitants. A shift in the course of the Euphrates River may have accelerated its final decline after the Parthian period. By 300 AD the city was mostly abandoned, though a group of Mandaeans settled in the ruins, as evidenced by finds of Mandaic incantation bowls. By around 700 AD, Uruk was completely silent. The Sîn-kāšid Palace, built during the Isin-Larsa period when Uruk briefly governed itself under a line of kings beginning with Sîn-kāšid around 1865 BC, stands as one of the last reminders that even in the city's long twilight, it retained rulers who called themselves king of Uruk.
