"Persia and the Persian Question", written in 1892, has been considered Curzon's "magnum opus" and can be seen as a sequel to "Russia in Central Asia." Curzon was commissioned by "The Times" to write several articles on the Persian political environment, but while there he decided to write a book on the country as whole. This two-volume work covers Persia's history and governmental structure, as well as graphics, maps and pictures (some taken by Curzon himself). Curzon was aided by General Albert Houtum-Schindler and the Royal Geographical Society (RGS), both of which helped him gain access to material to which as a foreigner he would not have been entitled to have access. General Schindler provided Curzon with information regarding Persia's geography and resources, as well as serving as an unofficial editor.
