The purpose of this paper is to examine previous studies about the Mujahidin movement. The Mujahidin movement was founded by Saiyid Aḥmad Barelvī and Shāh Muḥammad Ismā‘īl. The Mujahidin were mainly active in north India. In 1826, they started a Jihad against the Sikhs. British officers thought that the Mujahidin movement was affected by Arab Wahhābīs, and so they were labeled as ‘Indian Wahhābīs'. Western scholars tend to connect the Arab Wahhabis and the Indian Mujahidin, but their connection with the Arab Wahhabis has been denied by South Asian and Japanese scholars because of the difference of their attitudes toward Sufism and saint cults. They insist that Indian Mujahidin had a deep relationship with the family of Shāh Walī Allāh. Recently, a new paper revealed that this movement was influenced by a Yemeni scholar.The movement pursued many reforms such as the usage of lithography and the remarriage of widows. This had a big impact on South Asian societies in those days. Their reforms exerted influence on South Asian Islamic revivalist movements like the Deobandī, and today, this Jihad affects Islamic militants in Kashmir.
