The founder of the Third Dynasty of Ur was Ur-Nammu who probably came from Uruk, however he was a military commander (šagina) of Ur, and later its independent ruler who conducted victorious fights with the Gutians and took by force other lands of Sumer and consolidated the whole Akkad and Sumer. Moreover, he also conquered Elam and even reached Susa. His political power was related not only to his conquest, but mainly to his cultural and legislative activities. He was a builder of few great temples and was a lawgiver of one of the oldest ’code’ called Code of Ur-Nammu. [1] His son - Shulgi continued father’s politics and he "reorganized system and territorial administrative structure, but also much enlarged its lands and increased international prestige, turning it into a dominant power of the region." [2] He seized among other Simurrum, Lullubum, Kimaš, Hurti, Karahar, Šašrum, Harši. He used the political marriages and various alliances as well to cement his state (e. g. his daughters married the ruler of Marhaši and the ensi of Anshan). Two sons of Shulgi reigned 9 years each - Amar-Sin(Amar-Suen)and Shu-Sin(Su-Suen). Amar-Suen led few victorious campaigns against Urbilum, Šašrum and Hurrians. Su-Suen fight against Amorites, however his strategy was more defensive than offensive. The last king from this dynasty -Ibbi-Sin was less successful in fights with Amorites, Gutians and Elamites. After he was betrayed by the governor of Isin named Ishbi- Irra, the Ur became much weaker. Eventually the city of Ur was captured and looted in 2010 and Ibbi-Sin lost his throne and was transported to Susa. Generally speaking, the Ur III period is perceived as a flowering time when many significant changes took place, especially on the field of literature, culture and architecture. However, many important transformation concerning administration, army as well as the position of the ruler were happened. Ur is described often in the literature as "the centralized bureaucratic state" [3] with many civil servants and elaborated administration structures. According to Jason Ur: "The kings of Ur created centralized temple and above all royal administrative systems, and attempted to resuscitate a Sumerian identity. [4] The state of Ur consisted of three main zones: core, periphery and vassal territories. The core encompasses lands of Sumer and Akkad and it includes 18 provinces. The peripheral areas are defined as the land which were attached by Shulgi (in a consequence of his military activity) such as eastern Iraq, the western provinces of Kurdistan, Luristan, Khuzestan. The third zone, so called "sphere of influence" included vassal states. [5] Besides its military achievements, the marital alliances were often used tool to establish or broaden the power of Ur’s kings.

"The kings of Ur interacted with the regions of Anshan (Fars), Shimashki and Zabshali (north of Susiana) through a series of peace treaties, containment policies and threats. At times this interaction was expressed through marriages between the daughters of the kings of Ur and the Elamite kings, or military expeditions."

"In the Neo-Sumerian period, the population of Ur was ca. 200,000 people. Both this population increase and the urban improvements were largely supported by agricultural activities." [1] The territory of the largest cities is bigger than 200 ha ( e. g. Umma, Girsu, Lagash, Larsa, Isin, Suheri), the capital - Ur-50 ha, smaller cities- between 40-200ha (e. g. Zabalam, Adab), bigger towns - 20-40 ha (e.g. Wilaya), smaller towns - 10-20 ha and villages [2]

"The economy of earlier empires was predominantly based on commercial activities and political relations with states that were controlled by the centre and were dependent on it. However, the empires themselves did not directly control these resources. The direct management of resources was an innovation of the kings of Ur, who applied in throughout the centre of the empire, which was itself no longer divided into several tributary city-states, but into provinces governed by functionaries (the ensi) appointed by the kings of Ur. The bureaucratic management of these provinces was uniform and interchangeable, and could be applied throughout the land (although some some local variations remained in place)."
[2]
"Under Ur III control, Susiana was governed by an ensi appointed by the king. The area was therefore included in the Mesopotamian nucleus of the empire and fully integrated both on a political and administrative level. However, in the surrounding areas, the rest of Elam remained independent. In fact, from an Elamite perspective Susa was only a marginal city bordering with Sumer. The kings of Ur interacted with the regions of Anshan (Fars), Shimashki and Zabshali (north of Susiana) through a series of peace treaties, containment policies and threats. At times this interaction was expressed through marriages between the daughters of the kings of Ur and the Elamite kings, or military expeditions."
[3]
Inscriptions from time of Ur (Shu-Sin) suggest unity within internal land. "the celebratory tone was not directed against Mesopotamian cities or other urbanised centres (such as the ones in Elam and Syria) anymore. The inscriptions rather focused on those turbulent ’barbarian’ groups from the steppes and mountains, considered to be uncivilised and inhuman."
[4]
"The Ur III rulers imposed their suzerainty over the Elamite princes of Anshan, who were probably semi-nomadic, in the southeast, and over others, including the princes of Shimashki, in an area that is likely to have extended to the north and southeast of Susiana."
[5]
"With the rise of Ur, cities lost their traditional autonomy (which is an entirely different concept from their fluctuating state of independence). They were still ruled by an ensi. Now, however, the title did not designate a local ruler governing on behalf of the local city-god. The ensi became a governor, appointed by Ur and acting on behalf of the king of Ur".
[6]
"The deified kings of Ur consequently replaced the city-gods as ultimate heads of the land. They therefore controlled the entire production and redistributive system, whose management was inevitably delegated to the local ensi."
[6]
"The substitution of local rulers with functionaries appointed by Ur could not have been welcomed without opposition and conflict."
[6]
"The farming of sheep was mainly focused on the production of wool. When a herd was entrusted to a shepherd its composition was recorded and the parameters of births and deaths were established. Similarly the quantity of wool to be produced was calculated, keeping in mind the differences between sheep and rams, as well as their size. Wool was then rank according to its quality (there were at least six or more categories) and sent to manufacturing centres. Each operation had its own parameters. The administration took into account losses during manufacturing (carding, spinning and washing) and the working days it required. Consequently, a given amount of wool needed a certain number of working days to produce a certain quantity of thread (either warp thread or weaving thread). In order to produce a fabric of given dimensions, then, the administration knew the quantity of working days and warp and weaving thread required. It was then able to calculate the cost and raw materials needed before the whole operation even began."

It appears that temple structures were used for the purposes of state administration. Livernai writes that the temple ’was the unit at the heart of the state administration, and was only accessible to the sons of the ruling class (sons of ensi and high officials, as well as scribes)’. [1]

"The first evidence of the composite bow appears on the victory stele of Naram Sin (2254-2218 B.C.E.)". [1] "The effective range of the simple bow varied from 50 to 100 yards. And the arrow shot by a simple bow was unable to penetrate leather or bronze armour. The effective range of the composite bows varied between 250 and 300 yards." [2] However, the composite bow itself could not penetrate armour more than 2mm thick [all designs or just the early designs?] and was susceptible to rotting in high-moisture environments. [1] "The composite bow was a recurve bow made of wood, horn and tendons from oxen, carefully laminated together. These bows were probably invented by the nomads of the Eurasian steppe and brought into Sumer by the mercenary nomads." [2] "Composite bows are known from both Mesopotamia and the Great Steppe from the III millennium BCE."

In Sumer the first swords appeared about c3000 BCE but until c2000 BCE their use were restricted because the blade often became detached from the handle. The sickle-sword of c2500 BCE was cast whole but it was unable to break armour so the battle axe was preferred.

"The first recorded instance of body armor is found on the Stele of Vultures in ancient Sumer, which shows Eannatum’s soldiers wearing leather cloaks on which are sewn spined metal disks. The disks do not appear to be arranged in any order, and we do not know if the disks were made of copper or bronze. By 2100 BCE the victory stele of Naram Sin appears to show plate armor, and it is likely that plate armor had been in wide use for a few hundred years. Plate armor was constructed of thin bronze plates sewn to a leather shirt or jerkin." [1]
