This book offers a biopolitical analysis of J. K. Rowling's globally-known Harry Potter series, including Jack Thorne and John Tiffany's stage production of Rowling's story, Harry Potter and the Cursed Child (2016). It indicates that modern children's fantasy school stories both perpetuate power inequalities as an effective dispositif of bioengineering, and simultaneously provide a political dissident perspective to power relations through an impossible fantasy world parallel to the real one. It applies Michel Foucault's biopolitical analytics, referring to his key works to reveal that race and class are used interactively as an agent for the exercise of biopower, in addition to Michael Hardt and Antonio Negri's rereading of Foucauldian biopolitics and biopower, introducing the concepts of multitude, the common, and the Empire to decipher the relationship between power and resistance besides the types and results of resistance in relation to biopolitics and biopower. As such, the book will appeal to undergraduates, academics, and all readers interested in modern fantasy works and school stories as well as critical theories, including those of Foucault and Hardt and Negri, particularly biopolitical analytics.
