Isi-Sumuabi

Isi-Sumuabi or Iṣī-Sumuabu was king of Hana, in the Early Hana period (c. 1750-1595 BC).

Reign After Hammurabi of Babylon had destroyed the city of Mari, the Kingdom of Hana was established with its capital at Terqa. During this time, Terqa's eastern border seems to have included Tabatum in the northeast and warring with Babylon for the control of Harradum on the Euphrates River in the southeast.

In the Old Babylonian period, Isi-Sumuabi was the second king of Terqa. He is known from a number of clay tablets from the city of Ṭābatum.

Tabatum was on the middle reaches of the H̬abur, which belonged to his kingdom. Two of these are letters to Yasīm-Mahar, who was his local governor. There are two other tablets in which he is mentioned. They are of a legal-administrative nature. One of them deals with the monthly rotation in connection with the pudûm ceremony for the sun god Šamaš . His name appears in the year name with which the tablet is dated: the "year that Iṣī-Sumuabi ... dedicated to Šamaš". This immediately makes his royal dignity crystal clear and the fact that in Ṭābatum the calendar was based on his regnal years. The other tablet concerns the grant of a piece of land in which he is called "king". The tablet also clearly shows that it was written in the legal tradition of H̬ana. The punishment for breaking the contract is to be smeared with hot asphalt . It dates from a different year, the year name of which refers to a project in which work was being done on the course of the river. The king is also mentioned elsewhere, for example in a contract found in Terqa which was further downstream on the Euphrates River. There is also a contract from Haradum, another 90 km further downstream in which he is mentioned. With this he ruled over an area not much inferior to the land of Zimri-Lim of Mari .

A possible attestation is a year-name of Isi-Sumu-Abum (BM 80338).
