Piyassili

Who is Piyassili?

Piyassili was a Hittite prince, and a middle son of King Suppiluliuma I; younger than the heir Arnuwanda II, but older than the eventual successor Mursili II and probably older than the doomed Zannanza too. After Suppiluliuma concluded a treaty with Shattiwazza, son of King Tushratta of Mitanni, and married one of his daughters to him, Piyassili led a Hittite army that put Shattiwazza on the throne of Hanigalbat. According to Hittite sources, Piyashshili and Shattiwazza crossed the Euphrates at Carchemish, then marched against Irridu, already in Hurrian territory. After having reduced Irridu and Harran, they continued east towards Washshukanni and perhaps conquered the capital Taite as well.
