Why is there so much attention on Kant's global politics in present day law and philosophy? This book highlights the potential fruitfulness of Kant's cosmopolitan thought for understanding the complexities of the contemporary political world. It adopts a double methodological strategy by reconstructing a genealogical conceptual journey showing the development of international law, as well as introducing an interpretation of cosmopolitanism centred on Kant's theory of a metaphysics of freedom. The result is a novel focus on Kant's notion of the world republic. The hypothesis here defended is that the world republic stands as a way of thinking about international politics where the possibility of progression towards peace results from its use as a regulative idea.
