Steve Coll’s The Bin Ladens: An Arabian Family in the American Century is the groundbreaking history of a family and its fortune. It chronicles a young illiterate Yemeni bricklayer, Mohamed Bin Laden, who went to the new, oil-rich country of Saudi Arabia and quickly became a vital figure in its development, building great mosques and highways and making himself and many of his children millionaires. It is also a story of the Saudi royal family, whom the Bin Ladens served loyally and without whose capricious favor they would have been nothing. And it is a story of tensions and contradictions in a country founded on extreme religious purity, which then became awash in oil money and dazzled by the temptations of the West. In only two generations the Bin Ladens moved from a famine-stricken desert canyon to luxury jets, yachts, and private compounds around the world, even going into business with Hollywood celebrities. These religious and cultural gyrations resulted in everything from enthusiasm for America—exemplified by Osama’s free-living pilot brother Salem—to an overwhelming determination to destroy it.
