Who’s Who in the Middle Ages [PDF ebook] 

From Abelard to Zubaydah, here is a biographical dictionary of notable men and women of the Middle Ages. Hundreds of entries span the fifth to the fifteenth centuries, covering a broad range of creative, vigorous, and influential people from Europe and the Middle East. Each entry includes both personal and historical details, alternate name spellings, and references for further reading. A rich selection of appendices includes a chronology of events; a chronology of popes, emperors and monarchs; a list of colleges and universities of the Middle Ages; a list of major monasteries, abbeys, and convents and an alphabetical list of individuals by occupation.
