This volume brings together a set of widely scattered articles spanning some thirty years of research on early and medieval Yemen and South Arabia. They cover the political and military history of the area, from the beginning of Islam to the Ottoman conquest in 1517, with the establishment of the Zaydis and then the Ayyubids as key events. Particular attention is given to the 13th century, and questions of trade and historical geography. The work of the traveller Ibn al-Mujawir, the subject of a series of studies, also provides much information on the society and beliefs of the period, including magic and sexual practices.
