Wahhabism has been generating controversy since it first emerged in Arabia in the 18th century. In the wake of September 11th instant theories have emerged that try to root Osama Bin Laden’s attacks on Wahhabism. Muslim critics have dismissed this conservative interpretation of Islam that is the official creed of Saudi Arabia as an unorthodox innovation that manipulated a suggestible people to gain political influence. David Commins’ book questions this assumption. He examines the debate on the nature of Wahhabism, and offers original findings on its ascendance in Saudi Arabia and spread throughout other parts of the Muslim world such as Afghanistan and Pakistan. He also assesses the challenge that radical militants within Saudi Arabia pose to the region, and draws conclusions which will concern all those who follow events in the Kingdom. "The Wahhabi Mission and Saudi Arabia" is an essential reading for anyone interested in the Middle East and Islamic radicalism today.
