Reinhold Niebuhr (1892-1971) is perhaps the best known North American theologian of the twentieth century. Over the course of his life he was a Christian socialist, pacifist, a staunch anti-communist, and an architect of vital-centre liberalism. Niebuhr wrote on themes as diverse as war, democracy, world order, political economy and race. So significant was Niebuhr's intellectual influence that George Kennan once described him as 'the father of us all'. Indeed, from the thought of Barack Obama to Jimmy Carter, Martin Luther King Jr. to Arthur Schlesinger Jr., Hans Morgenthau to Kenneth Waltz, E.H. Carr to Jean Bethke Elshtain, Niebuhr has helped shape International Relations. Bringing together intellectual historians and international political theorists, this special issue asks whether Niebuhr's thought remains relevant to our times? Can he help us think about democracy, power, race, the use of force, and cruelty in a moment when ethnonationalism appears ascendant and democracy in decline?
