The next mention of Qatna after the "Story of Sinuhe" comes from Mari in the 18th century BC, during the reign of Išḫi-Addu of Qatna. However, a tablet found in Tuttul, dating to the early reign of the Mariote king Yahdun-Lim in the late 19th century BC, mentions a king named Amut-piʾel, who is most probably the father of Išḫi-Addu; this would make him the first known king of Qatna. Also during the reign of Yahdun-Lim, the kingdom of Yamhad in Aleppo and its king Sumu-Epuh enter the historical record through the texts of Mari.
