An academic history can mean a large multivolume work such as the Cambridge Modern History written collaboratively under some central editorial control. In the 19th century the idea appeared in universities that a definitive history could be written of a major region of the world for a great span of time in a similar manner to the way that an encyclopedia was written. The time period was subdivided into eras and one volume specified for each.
