"Abdelaziz was the descendant of Muhammad ibn (son of) Saud, founder of the Al-Saud dynasty. From the deep interior of Najd, Abdelaziz brought with him two centuries of a particular brand of Islam that his ancestors had espoused in a political and familial alliance with one man: Muhammad ibn Abdelwahhab. Ultra-orthodox and fundamentalist, the eighteenth-century religious preacher led an exclusionary revivalist movement, following in the footsteps of others who had called for a return to the ways of the salaf, the ancestors, the first generation of Muslims. There were those Salafists who believed that following the righteous salaf, al-salaf al-saleh, dictated a return to the exact way of life of the prophet. In the early twentieth century, there would be modernist Salafists, such as the Egyptian Muhammad Abduh, who believed it was important to rid Islam of centuries of acquired traditions and accretions and return to the purity of prophet’s teachings, which actually provided the answers needed to adapt religion to modernity. Only after 9/11 did the term Salafist become known worldwide, used exclusively to denote the stricter outlook with Salafist jihadists resorting to violence to impose their views."
