The terrorist attacks of September 11, 2001, and subsequent discussions of religious extremism have called attention to Islamic puritanical movements known as Wahhabism and Salafiyya.

Saudi officials strenuously deny these allegations. This report provides a background on Wahhabism and its relationship to active terrorist groups; it also summarizes recent charges against Wahhabism and responses, including the findings of the final report of the 9/11 Commission and relevant legislation in the 110th Congress.
