Until the period following World War I the Near East and the Middle East coexisted, but they were not always seen as distinct. Bertram Lenox Simpson, a colonial officer killed eventually in China, uses the terms together in his 1910 book, The Conflict of Color, as "the Near and Middle East." The total super-region consisted of "India, Afghanistan, Persia, Arabistan, Asia Minor, and last, but not least, Egypt." Simpson (under his pen-name, Weale) explains that this entire region "is politically one region – in spite of the divisions into which it is academically divided." His own term revives "the Nearer East" as opposed to "the Far East."
