Niya may refer to
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.
EA 53 is a 70–line letter of area intrigues, -(written by "Prince Akizzi" of Qatna). The letter starting at line 35:
The ruins of Niya (simplified Chinese: 尼雅遗址; traditional Chinese: 尼雅遺址; pinyin: Níyǎ Yízhǐ), is an archaeological site located about 115 km (71 mi) north of modern Minfeng Town (also called Niya) on the southern edge of the Tarim Basin in modern-day Xinjiang, China. The ancient site was known in its native language as Caḍ́ota, and in Chinese during the Han Dynasty as Jingjue (Chinese: 精絕; pinyin: Jīngjué). Numerous ancient archaeological artifacts have been uncovered at the site.
Niya was once a major commercial center on an oasis on the southern branch of the Silk Road in the southern Taklamakan Desert. During ancient times camel caravans would cut through, carrying goods from China to Central Asia.
In Hanshu, an independent oasis state called Jingjue, generally thought to be Niya, is mentioned:
Niya became part of Loulan Kingdom by the third century. Towards the end of the fourth century it was under Chinese suzerainty, later it was conquered by Tibet.
