International propagation of the Salafi movement and Wahhabism

Starting in the mid-1970s and 1980s, the international propagation of Salafism and Wahhabism within Sunni Islam and throughout the Muslim world, favored by the conservative oil-exporting Kingdom of Saudi Arabia and other Gulf monarchies, achieved a "preeminent position of strength in the global expression of Islam". The Saudi interpretation of Islam not only includes Salafism and Wahhabism but also Islamist and revivalist interpretations of Islam, and a "hybrid" of the two interpretations (until the 1990s).
