Хаттусили III
Hartapu, who bore the titles Great king, and Hero, states himself to be the son of another Great King and Hero named Mursili. This Mursili likely is identical to the Hittite Great King Mursili III, better known under his birth name Urḫi-Teššub, who ruled the Hittite empire in 1272-1267 BC before being dethroned by his uncle Hattusili III.
