What is "nuhasse"

Nuhašše, also Nuhašša, was a territory in the Syrian region mentioned in various Middle Eastern documents as between Mari on the Euphrates and Hamath. The 1350 BC Amarna letters correspondence refers to Nuhašše in 11 tablet-letters written in Akkadian cuneiform.

The region was generally south of Aleppo. In the Amarna letters, Nuhašše was ruled by Addu-nirari, letter EA 51, ( EA for 'el Amarna').
