Wahhabi movement
The movement developed across various regions of the Islamic World in the late 19th century as a response to Western European imperialism. It was also influenced by the various Islamic 18th-century reform movements such as the Wahhabi movement in the Arabian Peninsula, subcontinental reform movements spearheaded by Shah Waliullah Dehlawi, Shah Ismail Dehlawi and Sayyid Ahmad Shaheed as well as the Yemeni "islah" movement led by Al-San'aani and Al-Shawkani.
