Niya, Niye, and also Niy of Thutmose I's Ancient Egypt, also Nii of the Amarna letters, and Nihe, etc. was a kingdom in Syria, or northern Syria.
In the Amarna letters correspondence of 1350- 1335 BC, Nii is only referenced in two letters, but each is of some importance. The city of Tunip in the northern Levant had been trying to communicate to the Egyptian pharaoh for two decades, and finally resorted to another letter, EA 59: entitled: "From the citizens of Tunip", ( EA for 'el Amarna'). The city-state of Arqa also sent a letter to pharaoh, requesting aid (EA 100).
The other letter referencing Nii concerns the individual Etakkama, his collusion with the Hittites, and the takeover of territory, 'city-states', and peoples in the northern and western Levant.
