Kuzi-Teshub in Wikipedia

Kuzi-Teshub was the son of Talmi-Teshub who was both the last viceroy of the Hittite Empire at Carchemish under Suppiluliuma II, and a direct descendant of Suppiluliuma I.[1] He succeeded his father in office according to royal seal impressions found at Lidar Höyük in 1985 on the east bank of the Euphrates river. Kuzi-Teshub then styled himself as "Great King" of Carchemish suggesting that the central Hittite dynasty at Hattusa had collapsed by his time and that he viewed himself as the one true heir of the line of Suppiluliuma I.[2]
