The term world government refers to the unification of all human beings under a single political entity. Since antiquity the concept has fallen in and out of favor, over history and through different regimes of social thought and political organization. Philosophers and scholars from a variety of disciplines have appealed to this idea at times as a solution to end wars or in hopes of realizing unity under one God. Discussions regarding world government have gained renewed impetus in the globalizing post–Cold War era, with social scientists and political philosophers alike reviving the notion as a solution to global injustices and rising security threats. Within the field of international relations, scholars mostly discuss the possibility of a world government as a guarantor of world peace and an alternative to the realist conception of “anarchy” in the international arena. Additionally, the idea has been taken up by some normative political theorists and economists, who stress the need for international or supranational regulation due to the perceived inability of nation‐states to address global problems of poverty, environmental degradation, migration, and financial regulation.
