Isputahsu (also transliterated as Ià ¡putaá¸«à ¡u) was a king of Kizzuwatna, probably during the late 16th century BC (middle chronology). He signed a treaty of alliance with the Hittite king Telepinu.
His father was Pariyawatri, who maybe was not a king.
The name of Isputahsu is Hittite and not Luwian.
The first king of free Cilicia, Isputahsu was recorded as a "great king" in both cuneiform and Hittite hieroglyphs. A treaty between Ishputahshu and Telepinu is recorded in both Hittite and Akkadian.
