The review forum on The Birth of Territory in Journal of Historical Geography is now published. Reviews by Stephen Legg, Michael Heffernan, Briony McDonagh, Jeffrey Jerome Cohen and Saskia Sassen, and a response by me.
The full article requires subscription, but there is a preprint on academia.edu
Thanks again to Steve for organising this, and to Michael, Briony, Jeffrey and Saskia for their engagement with the book.
