Global blopolitics and the history of world health

Many scholars have historicized biopolitics with reference to the emergence of sovereign nations and their colonial extensions over the 18th, 19th and 20th centuries. This article begins to conceptualize and trace the history of biopolitics beyond the nation, arguing that the history of world health-the great 20th-century reach of 19th-century health and hygiene-should be understood as a vital politics of population on a newly large field of play. This substantive history of world health and world population is analysed as sites for thinking about global biopolitics; and the article looks seriously at the interwar period as a point at which 'the world' (or Hardt and Negri's 'Ernpire') was already challenging the idea of 'inter/national'.
