David Storey reviews The Birth of Territory in Journal of Historical Geography (requires subscription or email me). Here’s the final paragraph.

This is a work of history, political science, law and philosophy as well as a work of geography. In telling the story of territory, Elden also touches usefully on a range of other issues such as the periodization of history and the retrospective application of terms such as ‘middle ages’ and ‘renaissance’. The meticulousness of the research is evident in the extensive footnotes, with 2750 in total and running to almost 150 pages. The breadth of sources and the range of ideas mean that Elden is, in many respects, following on in a similar vein to many of the writers whose work he deals with here.
