In a clear and luminous way, Graziano demonstrates how religions, in the plural, came to reinvest in the political sphere and provides his readers with a full comprehension of the geopolitical dynamics at work in our world today. -- Souleymane Bachir Diagne, Columbia University It has become commonplace that the old certainties that governed postwar politics are dissolving in the heat of populism and nationalism. Graziano argues that the change is in fact deeper than this: having been thoroughly secularized after the Treaty of Westphalia in 1648, global politics is once more coming to terms with the power of religion.
