Wahhabism

Wahhabism is the Sunni Islamic reform movement founded by Muhammad ibn Abd al-Wahhab in 18th-century Najd, in central Arabia. It calls for a return to strict monotheism and rejects the veneration of saints and tombs. Its alliance with the Al Saud in 1744 created the Emirate of Diriyah, which Muhammad Ali's Egyptian armies destroyed in 1818, and it remained the religious basis of later Saudi states.
