Hassum (also given as Khashshum, Ḫaššum, Hassu, Hassuwa or Hazuwan) was a Hurrian city-state,[1] located in southern Turkey most probably on the Euphrates river north of Carchemish.
[6] According to Archi (2011), Hassuwan can be identified with "Tilbeshar (south of Gaziantep, on the latitude of Karkamiš), a tell presenting the typical morphology of a great Middle Bronze Age city".
[7] In the beginning of 18th century BC, Hassum allied with Yamhad against Yahdun-Lim of Mari,[8] it later helped Yamhad against a kingdom in Zalmakum (a marshy region between the Euphrates and lower Balikh),[9] but then shifted alliance to Shamshi-Adad I of Assyria after he annexed Mari.
[12] In the course of his war against Yamhad, Hattusili I of the Hittites, having destroyed Alalakh and Urshu, headed toward Hassum in his sixth year (around 1644 BC, middle chronology).
[19] The king of Hassum was captured and humiliated, he was harnessed to one of the wagons used to transport the loot of his city and taken to the Hittite capital.
