Gungunum (, Dgu-un-gu-nu-um; (died 1906 BC) was a king of the city state of Larsa in southern Mesopotamia, ruling from c. 1932 to c. 1906 BC. According to the traditional king list for Larsa, he was the fifth to rule the city, and in his own inscriptions he identifies himself as a son of Samium and brother to his immediate predecessor Zabaya. His name is Amorite, and originates in the word gungun, meaning "protection", "defence" or "shelter".Fitzgerald 2002, p. 37-38

During the time Gungunum occupied the throne, Larsa went from being a city of lesser importance to become a powerful challenger to Isin, the dominant power in southern Mesopotamia since the fall of the Ur in 2002 BC. Gungunum's reign of 27 years is also much better documented than those of his predecessors, as we have a complete chronological list of all his year names, as well as four of his royal inscriptions. This is in contrast to the complete lack of year names from the preceding period, which makes his reign a watershed moment in terms of gaining an understanding of the history of Larsa and the surrounding region.Fitzgerald 2002, p. 38

Gungunum was the contemporary of the kings Lipit-Ishtar and Ur-Ninurta of Isin.Fitzgerald 2002, p. 159–160

Reign

Early years and military campaigns against Elam

When Gungunum succeeded his brother Zabaya in 1932 BC, Larsa seems to have been a minor power on the Mesopotamian political scene. However, it did not take long for Gungunum to make his mark on the region's political landscape, as his year names record that he conducted two military campaigns directed against Elam early in his reign. The first of these took place in his third year, when he attacked and destroyed Bašime,Fitzgerald 2002, p. 38-39 an Elamite region that was most likely located along the Iranian coast of the Persian Gulf from southern Khuzestan in the north to Bushehr in the south.Steinkeller 1982, p. 240–243

Gungunum followed up on this victory by conducting another campaign in his fifth year, this time by attacking and destroying Anšan, one of Elam's largest and most important cities. While these expeditions must have brought Gungunum vast riches and great political prestige, it is otherwise unknown what might have spurred him to embark on these eastern expeditions. One possibility is that Anšan had maintained an alliance with Isin, as it is known that such an alliance had been concluded 45 years prior when king Iddin-Dagan of Isin gave his daughter in marriage to the ruler of Anšan.Fitzgerald 2002, s. 39 If this was the case, then Gungunum's campaigns can be understood as a successful attempt to free his eastern flank before challenging Isin's regional supremacy directly.

The period following Gungunum's two campaigns against Elam seems to have been relatively quiet, as his subsequent four year names are devoted to the maintenance of Larsa's city god Utu, including the nomination of a new high priestess and the introduction of a large copper statue in Utu's sanctuary.Fitzgerald 2002, s. 39

Ur Gungunum's first major success in the struggle against Isin was his conquest of Ur, which had been part of Isin's domains since shortly after its fall to Elamite invaders around 2002 BC. While no direct reference to Gungunum's conquest is found in the written sources, the year names on documents found in Ur clearly show that control of the city changed hands from Isin to Larsa, as those belonging to Lipit-Ištar of Isin abruptly give way to those of Gungunum. The exact year of Gungunum's capture of Ur cannot be determined with certainty, but the year names found so far suggest that it took place in either his seventh or his 10th year, i.e. 1926 or 1923 BC.A document carrying the year name for Gungunum's seventh year has been found in Ur, but since this year name is identical with the year name designating king Abi-sare of Larsa's 11th year (i.e. 1895 BC), it is possible that it rather belongs to this king instead. The year name for Gungunum's tenth year is on the other hand definitely attested in Ur. See Charpin 2004, p. 71, footnote 223 It is also from Gungunum's 10th year that the content of his year names starts referring directly to Ur, with every single year name between his tenth and 14th years relating to religious activities taking place in the city, including the introduction of two standards in the temple of Ur's patron deity Nanna and the dedication of a statue, probably of Gungunum himself, to the same deity.Fitzgerald 2002, p. 40-41 As a result, there cannot be any doubt that Ur had been fully secured by the king of Larsa by this time, and that he was engaged in an effort to consolidate his power by developing his relationship to its main deities and their priests and high officials.

The conquest of Ur must have had a considerable impact on the balance of power between Isin and Larsa. Control of the old imperial capital was an ideological cornerstone to Isin's claim of being the rightful successor state to the Ur III empire,McIntosh 2005, p. 84 at the same time as Ur's southern location made the city into a trading hub and economic center connected to the trade networks running across the Persian Gulf.Charpin 2004, p. 72 While the attainment of such a prize must have been a great triumph for Gungunum and his kingdom, he nevertheless seems to have respected the integrity of Ur's established institutions, despite the fact that many of these were run by personnel appointed by the kings of Isin. This is demonstrated by the year name for his 13th year, which describes the installment of the previously appointed Enninsunzi, daughter of the recently deceased king Lipit-Ištar of Isin, as high priestess in the temple of Nin-gublaga. In addition, we know that Enanatuma, high priestess of Nanna and daughter of Lipit-Ištar's predecessor Ishme-Dagan, remained in place as the Ur's chief religious authority under Gungunum and even dedicated several religious buildings to him.Fitzgerald 2002, p. 41-42

There are further references to military clashes between Larsa and Isin from the period during which Ur fell under Larsa's suzerainty. These include two literary letters purporting to be an exchange between Lipit-Ištar of Isin and his general, Nanna-kiag, in which the latter asks for reinforcements from the king to halt the advance of Gungunum and his forces, who have "taken the road house" and are threatening to take over several water ways.Fitzgerald 2002, p. 42-44 Provided that the content of these letters refers to actual events, they further demonstrate the high level of conflict between Gungunum and Lipit-Ishtar at the time when both these kings ruled their respective cities. This antagonistic relationship between the two cities remained in place following the death of Lipit-Ishtar around 1924 BC and the ascendance of his successor Ur-Ninurta, although there seem to have been occasional moments of détente, such as in two known cases where Gungunum allowed his newly enthroned colleague in Isin to send his offerings to Ningal's temple in Ur.Charpin 2004, p. 72

Kisurra and quiet middle years Another locality that seems to have changed hands around the same time is Kisurra, a modestly sized city situated only 20 km southeast of IsinCharpin 2004, p. 74 that had probably been part of Isin's domains ever since the end of the Ur III empire. However, no inscriptions or dated documents have been found from the long period of Isin's domination; instead, the oldest dated document unearthed in Kisurra so far carries the year name of Gungunum's tenth year, i.e. 1923 BC. This means that the king of Larsa in all probability held the city this year, although it is not possible to determine whether this also was the year when he first seized it, or if this had happened at an earlier point in time. Kisurra did in any case not remain under Larsa's control for long, for the next year name found in the city belongs to Ur-Ninurta's fourth year, i.e. 1921 BC, which means that the king of Isin must have conducted a counter-offensive that brought Kisurra back into his hands.Tyborowski 2012, p. 252

Following the loss of Kisurra, the reign of Gungunum seems to have entered a calmer phase, at least according to the year names from his 13th to 18th regnal years, which only concern religious affairs and the construction of irrigation canals and temples. These include the construction of a temple for Inanna in Larsa in his 16th year and a temple for the deity Lugalkiduna in Kutalla, a town in the immediate vicinity of Larsa, in his 18th year.Fitzgerald 2002, p. 42

Malgium, Uruk and Nippur

According to the year name for Gungunum's 19th year, i.e. 1914 BC, the king of Larsa destroyed the army of Malgium, "secured the road-house" and "opened the source of the mountain canal" at the command of the gods An, Enlil and Nanna.Fitzgerald 2002, p. 42 While it is difficult to determine the exact meaning of the latter two statements, the victory against Malgium provides a clear indication of a northern campaign along the Tigris on Gungunum's part, as the city of Malgium was located somewhere on the banks of this great river between Mashkan-shapir and its confluence with the Diyala river further north.Bryce 2009, p. 441 This region is situated well northeast of Isin, and Gungunum's incursion into the area shows that Larsa now possessed a military reach that extended farther north than ever before.

The same year name provides further evidence of Larsa's expansion under Gungunum by way of its reference to An, Enlil and Nanna, which are the titulary deities of Uruk, Nippur, and Ur, respectively. While Gungunum's authority in Ur was well established at this point, the reference to the two other deities indicates that he might have seized power in Uruk and Nippur as well.Fitzgerald 2002, p. 42 In the case of Uruk, which is located only 25 km northwest of Larsa, it is known that the city previously had been held by Isin until the reign of Lipit-Ištar.Frayne 1990, s. 439 Following the death of Lipit-Ištar, however, the political status of Uruk becomes highly uncertain, and there is a clear possibility that Gungunum may have managed to bring the city under his rule. Such a scenario is furthermore supported by the discovery of bricks inscribed with Gungunum's name at a place called Umm al-Wawiya,Charpin 2004, p. 72 which is located in the immediate vicinity of Uruk and may possibly be identified with the ancient town of Durum.Michalowski 1977, p. 88. But see Verkinderen (2006) for an alternative location of Durum This proximity of the king of Larsa to the very doorstep of Uruk further increases the probability that he also controlled the city itself.
