Kuqa, known in ancient times as the powerful kingdom of Qiuci, boasts a rich history spanning more than two millennia. The first references to it as a prosperous city-state date back to the beginning of the 1st millennium BCE. Initially, the oasis was inhabited by speakers of Tocharian languages. The city owes its emergence and development to its unique location at the foot of the Tian Shan mountains, in a fertile oasis amidst the Taklamakan Desert.
A key factor in the rise of Kuqa was its role as a vital hub on the northern branch of the Great Silk Road. This caravan route, connecting China with the countries of the Mediterranean, contributed to the city's economic prosperity. Its geographical position made Kuqa a crossroads of civilisations, where cultures of the East and West met and mingled. The city was not only a trade hub but also an important military-administrative centre, confirmed by the establishment of Chinese protectorates here during various historical periods.
In the early period of its history, Kuqa became famous as one of the largest centres of Buddhism in Central Asia. It housed around a hundred monasteries, and art and culture reached a high level, as evidenced by the unique frescoes in the nearby Kizil Cave temples. It was in Kuqa that Kumarajiva (344–413 CE) was born, one of the greatest translators of Buddhist sacred texts into Chinese. A cultural feature of the region was the "West Tocharian" (Kuchean) language — one of the extinct Indo-European languages. The city's economy was based not only on transit trade but also on developed agriculture, including the cultivation of grapes, pomegranates, and grains, as well as the mining of copper, iron, and other metals.
