Crude as it was, however, Wahhabism endured because of its ties with the Saud clan, which only strengthened over time through mutual support and intermarriage. In 1932, when the clan was established as the royal family of Saudi Arabia, the narrow, intolerant Wahhabi strain of Islam effectively became the established religion of the kingdom. And soon, with the Saudis' growing oil wealth, the Wahhabi religious establishment became one of the most richly funded and aggressive pros-elytizing bodies in the world, spreading an intolerant version of the faith that began to compete with other more tolerant and locally inflected varieties of Islam.
But if Islamism and Wahhabism emerged in the Arab core of the Muslim world, one of the ironic turns of recent history is that political Islam fared better beyond the Arab core than in it. An Islamic republic, albeit Shiite rather than Sunni, arose in Iran in 1979, and in both Turkey and Algeria, Islamist parties became important political players (at least until the one in Algeria proved too successful and was suppressed by the military). In nations of the Arab core, by contrast, Islamists have been tolerated—and often modestly encouraged—to the extent that they posed no direct threat to the political regimes. Those individuals who take Islamist notions too seriously, including bin Laden (whose unhappiness about the Saudi kingdom's close ties with the infidel Americans is now well known), have faced exile or worse. But, as the world has learned, those outcast Islamists have learned to operate quite effectively in strange lands, whether in Afghanistan or Europe or even the United States.
