Collapse of The Akkadian Empire

The Empire of Akkad collapsed in 2154 BC, within 180 years of its founding, ushering in a period of regional decline that lasted until the rise of the Third Dynasty of Ur in 2112 BC. By the end of the reign of Naram-Sin's son, Shar-kali-sharri (2217–2193 BC), the empire had weakened. There was a period of anarchy between 2192 BC and 2168 BC. Shu-Durul (2168–2154 BC) appears to have restored some centralized authority, however he was unable to prevent the empire eventually collapsing outright from the invasion of barbarian peoples from the Zagros Mountains known as the Gutians.

Little is known about the Gutian period, or how long it endured. Cuneiform sources suggest that the Gutians' administration showed little concern for maintaining agriculture, written records, or public safety; they reputedly released all farm animals to roam about Mesopotamia freely, and soon brought about famine and rocketing grain prices. The Sumerian king Ur-Nammu (2112–2095 BC) cleared the Gutians from Mesopotamia during his reign.

It has recently been suggested that the regional decline at the end of the Akkadian period (and First Intermediary Period of the Ancient Egyptian Old Kingdom) was associated with rapidly increasing aridity, and failing rainfall in the region of the Ancient Near East, caused by a global centennial-scale drought. H. Weiss et al. have shown "Archaeological and soil-stratigraphic data define the origin, growth, and collapse of Subir, the third millennium rain-fed agriculture civilization of northern Mesopotamia on the Habur Plains of Syria. At 2200 B. C., a marked increase in aridity and wind circulation, subsequent to a volcanic eruption, induced a considerable degradation of land-use conditions. After four centuries of urban life, this abrupt climatic change evidently caused abandonment of Tell Leilan, regional desertion, and collapse of the Akkadian empire based in southern Mesopotamia. Synchronous collapse in adjacent regions suggests that the impact of the abrupt climatic change was extensive.". Peter B. deMenocal, has shown there was an influence of the North Atlantic Oscillation on the stream flow of the Tigris and Euphrates at this time, which led to the collapse of the Akkadian Empire".

The Sumerian King List, describing the Akkadian Empire after the death of Shar-kali-shari, states:

"Who was king? Who was not king? Irgigi the king; Nanum, the king; Imi the king; Ilulu, the king—the four of them were kings but reigned only three years. Dudu reigned 21 years; Shu-Turul, the son of Dudu, reigned 15 years. … Agade was defeated and its kingship carried off to Uruk. In Uruk, Ur-ningin reigned 7 years, Ur-gigir, son of Ur-ningin, reigned 6 years; Kuda reigned 6 years; Puzur-ili reigned 5 years, Ur-Utu reigned 6 years. Uruk was smitten with weapons and its kingship carried off by the Gutian hordes.

However, there are no known year-names or other archaeological evidence verifying any of these later kings of Akkad or Uruk, apart from a single artifact referencing king Dudu of Akkad. The named kings of Uruk may have been contemporaries of the last kings of Akkad, but in any event could not have been very prominent.

In the Gutian hordes, (first reigned) a nameless king; (then) Imta reigned 3 years as king; Shulme reigned 6 years; Elulumesh reigned 6 years; Inimbakesh reigned 5 years; Igeshuash reigned 6 years; Iarlagab reigned 15 years; Ibate reigned 3 years; … reigned 3 years; Kurum reigned 1 year; … reigned 3 years; … reigned 2 years; Iararum reigned 2 years; Ibranum reigned 1 year; Hablum reigned 2 years; Puzur-Sin son of Hablum reigned 7 years; Iarlaganda reigned 7 years; … reigned 7 years; … reigned 40 days. Total 21 kings reigned 91 years, 40 days.

Evidence from Tell Leilan in Northern Mesopotamia shows what may have happened. The site was abandoned soon after the city's massive walls were constructed, its temple rebuilt and its grain production reorganised. The debris, dust and sand that followed show no trace of human activity. Soil samples show fine wind-blown sand, no trace of earthworm activity, reduced rainfall and indications of a drier and windier climate. Evidence shows that skeleton-thin sheep and cattle died of drought, and up to 28,000 people abandoned the site, seeking wetter areas elsewhere. Tell Brak shrank in size by 75%. Trade collapsed. Nomadic herders such as the Amorites moved herds closer to reliable water suppliers, bringing them into conflict with Akkadian populations. This climate-induced collapse seems to have affected the whole of the Middle East, and to have coincided with the collapse of the Egyptian Old Kingdom.

This collapse of rain-fed agriculture in the Upper Country meant the loss to southern Mesopotamia of the agrarian subsidies which had kept the Akkadian Empire solvent. Water levels within the Tigris and Euphrates fell 1.5 metres beneath the level of 2600 BC, and although they stabilised for a time during the following Ur III period, rivalries between pastoralists and farmers increased. Attempts were undertaken to prevent the former from herding their flocks in agricultural lands, such as the building of a 180 km (112 mi) wall known as the "Repeller of the Amorites" between the Tigris and Euphrates under the Ur III ruler Shu-Sin. Such attempts led to increased political instability; meanwhile, severe depopulation occurred to re-establish demographic equilibrium with the less favorable climatic conditions.

It has also been recently suggested that the rapid climatic collapse, marking the Akkadian Dark Age, may have been responsible for the religiously prescribed prohibition against the raising and consumption of pigs that spread through the Ancient Middle East from the end of the third millennium BC.

The period between ca. 2112 BC and 2004 BC is known as the Ur III period. Documents again began to be written in Sumerian, although Sumerian was becoming a purely literary or liturgical language, much as Latin later would be in Medieval Europe.
