Now represented by an extensive mound, the name of the modern archaeological site is Tell Atchana.

Alalakh was founded by the Amorites during the Middle Bronze Age in the 2nd millennium BC. The first palace was built c. 2000 BC, contemporary with the Third Dynasty of Ur.

The written history of the site may begin under the name Alakhtum, with tablets from Mari in the 18th century BC, when the city was part of the kingdom of Yamhad (modern Aleppo). A dossier of tablets records that King Sumu-epeh sold the territory of Alakhtum to his son-in-law Zimri-Lim, king of Mari, retaining for himself overlordship. After the fall of Mari in 1765 BC, Alalakh seems to have come once again under the authority of Yamhad. King Abban of Aleppo bestowed it upon his brother Yarim-Lim, to replace the city of Irridi, which Abban destroyed after it revolted against Yarim-Lim. A dynasty of Yarim-Lin's descendents was founded, under the hegemony of Aleppo, that lasted to the 16th century (according to the short chronology) at which time Alalakh was destroyed, most likely by Hittite king Hattusili I, in the second year of his campaigns.
