These two volumes present a conspectus of current research on the history and culture of early medieval Spain and Portugal, from the time of the Arab conquest in 711 up to the fall of the caliphate. They trace the impact of Islamisation on the pre-existing Roman and Visigothic political and social structures, the continuing interaction between Christian and Muslim, and describe the particular development and characteristics of Muslim Spain- al-Andalus. Together, they comprise 38 articles, of which 32 have been translated into English specially for this publication. The first volume focuses on political and social history, and looks in detail at settlement patterns and urbanisation; the second examines questions of language and covers the brilliant cultural and intellectual history of the period.
