Hattusili III
As king, Hattussili III sought to keep a correspondence with many different kingships in the surrounding areas. After his ascension to the throne, Hattusili III began a correspondence with Egyptian Pharaoh Ramesses II that culminated in the first ever recorded peace treaty, the Eternal Treaty (also known as the Treaty of Kadesh). This correspondence took place roughly fifteen years after the Battle of Kadesh.
