Little is known about Arabia in the sixth century CE. Yet from this distant time and place emerged a faith and an empire that stretched from the Iberian peninsula to India. Today, Muslims account for nearly a quarter of the global population. G. W. Bowersock seeks to illuminate this most obscure and yet most dynamic period in the history of Islam from the mid-sixth to mid-seventh century exploring why arid Arabia proved to be such fertile ground for Muhammad s prophetic message, and why that message spread so quickly to the wider world. In Muhammad's time Arabia stood at the crossroads of great empires, a place where Christianity, Judaism, and local polytheistic traditions vied for adherents. sakriti opis
