Wahhabi movement
With the Islamic revival, a new "fundamentalist" movement arose, with some different interpretations of Islam, which often placed an increased emphasis on jihad. The Wahhabi movement which spread across the Arabian peninsula starting in the 18th century, emphasized jihad as armed struggle. Wars against colonialist powers were often declared to be jihad: the Senussi religious order declared jihad against Italian control of Libya in 1912, and the "Mahdi" in the Sudan declared jihad against both the British and the Egyptians in 1881.
