The book’s structure blends history and geography. A good world atlas or a world historical atlas will be helpful in the reading. The historical arrangement of contents has six Parts” Classical, Mediaeval, Early Modern (Lands), Early Modern (Ideas), Late Eighteenth and Nineteenth Centuries, Twentieth Century. Although this sequence of periods and categories fits Western/European history best, it is also reasonably appropriate for Central Asia, India, and China. For other regions it is more arbitrary, and Classical and Mediaeval periods are merged. Because the Parts overlap and involve imprecise categories, in the List of Contents and Summaries no attempt is made to give dates for their beginning and end.
