Qinghai ( listen (help·info)) (Chinese: 青海; pinyin: Qīnghǎi; Wade–Giles: Ching Hai, pronounced [tɕʰíŋxàɪ̯]); Oirat Mongolian: Көкнуур (transcribed into Cyrillic); Tibetan: མཚོ་སྔོན་; Salar:[citation needed]) is a province of the People's Republic of China, named after Qinghai Lake. It borders Gansu on the northeast, the Xinjiang Autonomous Region on the northwest, Sichuan on the southeast, and Tibet Autonomous Region on the southwest.
A large part of Qinghai's area, until the early 20th century most often referred to by its Mongol name Kokonur in English, lies outside of China proper and has been an ethnic melting pot for centuries, mixing Tibetan, Han Chinese, Mongol, and Turkic influences. The eastern part of the area of Qinghai was under the control of the Han Dynasty about 2000 years ago. It was a battleground during the Tang and subsequent Chinese dynasties when they fought against successive Tibetan tribes.
In the middle of 3rd century CE, nomadic people related to Xianbei migrated to pasture lands around Koko Nur (Qinghai Lake) and established Tuyuhun Kingdom. Since the 7th century, Tuyuhun Kingdom was attacked by both the Tibetan Empire and Tang Dynasty as both of them sought control over trade routes. Military conflicts severely weakened the kingdom and it was incorporated into the Tibetan Empire. After the disintegration of the Tibetan Empire, small local factions emerged. They were under titular authority of China and Tibet but maintained their autonomy. During the period of Mongol Yuan Dynasty's administrative rule of Tibet, majority of Qinghai belonged to one of the three commandaries of the Tibetan region divided at that time, namely Amdo (Tibetan: ཨ༌མདོ; Chinese: 安多; pinyin: Ānduō).
