The goal of this ambitious series is to provide an accessible source of knowledge about the entire human past, for every curious person in every part of the world. It will comprise some two dozen volumes, of which some provide synoptic views of the history of particular regions while others consider the world as a whole during a particular period of time. The volumes are narrative in form, giving balanced attention to social and cultural history (in the broadest sense) as well as to institutional development and political change. Each provides a systematic account of a very large subject, but they are also both imaginative and interpretative. The Series is intended to be accessible to the widest possible readership, and the accessibility of its volumes is matched by the style of presentation and production.
