Kupanta-Kurunta, the "man of Arzawa," is recorded as defeated by the Hittite joint great kings Tudḫaliya II and Arnuwanda I, but avoiding capture and retaining his territory.
Kupanta-Kurunta defeated Madduwatta and invaded the latter's lands in turn, causing him to flee for his life and taking over his refuge Šalawašši.
[6] While doing so, Madduwatta assured the Hittite monarch of his loyalty, portraying his alliance with Kupanta-Kurunta as a ploy.
If a Hittite text is to be taken literally, that Madduwatta "took the whole land of Arzawa for himself," he might have eliminated Kupanta-Kurunta in the end.
[9] An obscure Uḫḫa-zalma (or Ḫuḫḫa-zalma), who concluded a treaty with Arnuwanda I, has been posited as a possible successor of Kupanta-Kurunta.
