Kutik-Inshushinak accordingly campaigned in the
Zagros mountains on their behalf. He was greatly successful as his conquests seem to have gone beyond the initial mission.
Akkadian period In the inscription of the "Table au Lion", he appears as "Puzur-Inshushin(ak)
Ensi (Governor) of
Susa,
Shakkanakku (Military Governor) of the country of
Elam" ( , a title used by his predecessors
Eshpum,
Epirmupi, and
Ili-ishmani as governors of Akkad for the territory of Elam. In another inscription, he calls himself the "Mighty King of Elam", suggesting an accession to independence from the weakening Kingdom of Akkad. Inscribed blocks found in the early excavations at Susa, apparently from a staircase, had separate partly fragmentary Akkadian language and Linear Elamite inscriptions on two separate topics. The Akkadian text mentions Puzur-Inshushinak described as "šakkanakku of the land of Elam". Under King
Shar-Kali-Sharri, Akkad weakened, allowing Elam to claim independence. He conquered
Anshan and managed to unite most of Elam into one kingdom. He built extensively on the citadel at Susa, and encouraged the use of the Linear Elamite script to write the
Elamite language. Most inscriptions in Linear Elamite date from the reign of Kutik-Inshushinak.
Ur III period At the beginning of Ur III period, inscriptions of
Ur-Nammu (r. 2112-2094 BC) refer to Puzur-Inshushinak. He conquered numerous cities in central Mesopotamia, including
Eshnunna and
Akkad, and probably
Akshak. His conquests probably encroached considerably on
Gutian territory, gravely weakening them, and making them unable to withstand the Neo-Sumerian revolt of
Utu-hengal. It is now known that his reign in Elam overlapped with that of
Ur-Nammu of
Ur-III, although the previous lengthy estimates of the duration of the intervening
Gutian dynasty and rule of
Utu-hengal of Uruk had not allowed for that synchronism. Ur-Nammu, who styled himself "King of Sumer and Akkad" is probably the one who, early in his reign, reconquered the northern territories that had been occupied by Puzur-Inshushinak, before going on to conquer
Susa. ==Death==
