Suppiluliuma I
After Suppiluliuma's kingdom collapsed, the Kaskians possibly took over control of Hatti. Hattusa itself was destroyed by fire, its site only re-occupied by a Phrygian fortress some 500 years later. Kuzi-Teshub, a ruler of Carchemish, would later assume the title of "Great King" since he was a direct descendant of Suppiluliuma I.
