This book traces the political evolution of the Iberian peninsula from a group of late Roman imperial provinces to the monarchies of the mid-fifteenth century. The book consists of a series of essays on the main chronological periods of medieval Spain, and sketches the major political, economic, social and intellectual features of each age and the interaction of Christian, Jew and Muslim. There is currently no other volume in English or Spanish that provides such a wealth of analysis or description and yet which covers the entire medieval period.
