As Mayor, Mallow leads the Foundation through its third Seldon Crisis. In this instance, the crisis involved an impending war with Korell and those remnants of the Empire which back them. Mallow's solution, reminiscent of Salvor Hardin's years before, is to make the Korellian economy (as well as the livelihood of its population) dependent on Foundation merchandise. The “war” ends three years later as one of "the least fought wars in Galactic History", as quoted in the Encyclopedia Galactica, and Mallow transforms the power and influence of the Foundation from chiefly religious to primarily economic, turning Terminus into a successful plutocracy.
