This essay seeks to show that military strategists have not only been acute philosophers of space but also philosophers of world history. The works of Albert Speer, Friedrich Ratzel, A. T. Mahan, Halford Mackinder, Carl Schmitt, Guilio Duohet, and Harlan K. Ullman are considered in terms of the ways in which space has been militarized, or rather how war spatializes world history. The geography of world history has been the topos of war.
