(Sha-mash-mudammiq or Sha-mash-mu-SIG or UTU-mu-SIG) Fourth King of the eighth dynasty of Babylon (dynasty "E"), successor of Mar-Biti-Ahhe-Iddina, a son of Nabu-Mukin-Apli. With Shamash - Babylon Mudammiq could not recover from their critical situation, not only because of the instability existing, motivated by the presence of semi-nomadic Aramaic, but also for the attacks on that, on two occasions, had to face - known by the synchronous Chronicle - brought against it by the Assyrian king Adad-Nirari II, who, excuse in a Babylonian alleged provocation, could wrest large parts of the East of the Tigristhe enclaves of Der, Arrapha and Lubdu, as well as the border cities of Hit and Zanqu. These losses forced Shamash-Mudammiq to accept a modification of borders, which were sealed with the marriage agreement between both kings, which took the respective daughters as wives. The last years of Shamash-Mudammiq passed in peace, although it is argued that he/she was most likely murdered. On his death, the throne passed to power of Nabu-Shuma-Ukin I, whose degree of kinship and relationship with Shamash-Mudammiq is unknown, although it is believed that it was his son.
