The Naqshbandiyya Mujaddidiyya order is among the world's largest and most geographically widespread Sufi orders, but it has long been assumed to be absent among Chinese-speaking Muslims. Despite a handful of isolated references to local Chinese Mujaddidī groups in studies of particular communities, comprehensive histories of Chinese Islams make no mention of the Mujaddidiyya, and histories of the Naqshbandiyya Mujaddidiyya make no reference to Chinese-speaking Muslims. This article demonstrates that the Mujaddidiyya order has not only been present at various times and places among Chinese Muslims, but has also played a role in the development of nearly all major strains of Islam in China proper, including those commonly known as the Gedimu, Jahriyya, Khāfiyya, Qādiriyya, and Ikhwān. The article also uses new primary sources to provide an account of how a Mujaddidī order expanded into Eastern Turkistan and was transmitted from there to Muslims in China proper. It shows that adaptation to local environments created distinctive forms of Mujaddidī Sufism, highlights Hui-Uyghur connections, and argues that South Asia deserves a central place in any account of Islam in China.
