Biopolitics is an intersectional field between biology and politics.
While the term is commonly attributed to Rudolf Kjellén in the 1920s who also coined the term geopolitics, it was actually coined by G.W.Harris as early as 1911. In contemporary US political science studies, usage of the term 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.
