Since April, Mohammed bin Salman, now 32, has been quietly orchestrating the appointments of a range of young princes in their late twenties or thirties to positions of power. They will likely be crucial to the success of his remodeling of the kingdom and could emerge as arbiters of power for decades to come. They are all either the grandsons or great grandsons of the kingdom’s founder, Ibn Saud, who died in 1953. Mohammed bin Salman is entirely prudent in promoting these younger cousins, appealing to their ambition and vanity, and securing their loyalty.
