Hattusili III

Hattusili III deposed his nephew Urhi-Teshub (Mursili III) in a coup, claiming the throne for himself. The usurpation led to internal conflict and Urhi-Teshub's exile, but Hattusili consolidated power and ruled for decades.

Hattusili III concluded a peace treaty with Pharaoh Ramesses II of Egypt, ending decades of conflict. The treaty, inscribed on silver tablets, established mutual non-aggression, extradition, and defensive alliance. It is the oldest known surviving peace treaty.

Hattusili III arranged the marriage of his daughter to Ramesses II, sealing the peace treaty. The diplomatic marriage strengthened ties between the Hittite and Egyptian royal families and ensured continued peace.
