Jonathan Berkey surveys the religious history of the peoples of the Near East from approximately 600 to 1800 c.e. After examining the religious scene in the Near East in late antiquity, he investigates Islam's first century, the "classical" period from the accession of the Abbasids to the rise of the Buyid amirs. He then traces the emergence of new forms of Islam in the middle period, deftly showing how Islam emerged slowly as part of a prolonged process.
