Governmentality and biopolitics has emerged as a chief source of scholarship and debate within contemporary international relations (IR), particularly among those involved in the sub-disciplines, Critical Security Studies and International Political Sociology. Governmentality, first and foremost, is a term coined by philosopher Michel Foucault, and refers to the way in which the state exercises control over, or governs, the body of its populace. Meanwhile, biopolitics, which was coined by Rudolf Kjellén, is an intersectional field between biology and politics. In contemporary US political science studies, usage of the term biopolitics is mostly divided between a poststructuralist group using the meaning assigned by Michel Foucault (denoting social and political power over life), and another group who uses it to denote studies relating biology and political science. The foci of literatures on governmentality and biopolitics are particularly agreeable to many scholars critical of traditional IR scholarship and its distinct articulation of “world politics.” The shifty nature of both concepts, as defined by Michel Foucault and the subsequent use by various scholars, presents challenges to setting any specific account of these terms; yet the blurriness of these concepts is what makes them productive, contrary to the zero-sum, rationalist accounts of power and behavior so central to much of conventional IR.
