In this book, based on lectures delivered at the Historical Society of
Israel, the famed historian G. W. Bowersock presents an examination of
political developments in the Arabian Peninsula on the eve of the rise of
Islam. Recounting the growth of Christian Ethiopia and the conflict with Jewish
Arabia, he describes the fall of Jerusalem at the hands of the late Sassanian
(Persian) Empire. He concludes that the Byzantine Empire's defeat of the
Sassanian forces, which destabilized the region, provided the opportunity for
the rise and military success of Islam in the seventh century. Using close
readings of surviving texts, Bowersock sheds new light on the complex causal
relationships among the Byzantine, Ethiopian, Persian, and emerging Islamic
forces.
