The History of Xinjiang concerns two main geographically, historically, and ethnically distinct regions with different historical names: Dzungaria north of the Tianshan Mountains; and the Tarim Basin south of the Tianshan Mountains, currently mainly inhabited by the Uyghurs. They were renamed Xinjiang in 1884, meaning "new frontier," when both regions were reconquered by the Chinese Qing dynasty after the Dungan revolt (1862–1877).
