Taking advantage of the power vacuum in the region, Parshatatar, king of the Hurrian kingdom of Mitanni instigated a rebellion that ended the life of Yamhad last king Ilim-Ilimma I in c. 1525 BC, Subsequently, Parshatatar conquered Aleppo and the city found itself on the frontline in the struggle between the Mitanni, the Hittites and Egypt. Niqmepa of Alalakh who descends from the old Yamhadite kings controlled the city as a vassal to Mitanni and was attacked by Tudhaliya I of the Hittites as a retaliation for his alliance to Mitanni. Later the Hittite king Suppiluliumas I permanently defeated Mitanni, and conquered Aleppo in the 14th century BC. Suppiluliumas installed his son Telepinus as king and a dynasty of Suppiluliumas descendants ruled Aleppo until the Late Bronze Age collapse.
