For five years during the twelfth century, Margaret of Navarre, Queen of Sicily, was the most powerful woman in Europe and the Mediterranean. Her life and times make for the compelling story of a wife, sister, mother and leader. This is the first biography of the great-granddaughter of El Cid and friend of Thomas Becket who could govern a nation and inspire millions. In Margaret's story sisterhood is just the beginning. The Basque princess who rose to confront unimagined adversity became the epitome of medieval womanhood in a world dominated by men, governing one of the wealthiest, most powerful -- and most socially complex -- states of Europe and the Mediterranean. This book is the result of original, scholarly research in medieval chronicles and manuscripts -- some never before translated into English - yet its narrative is lively and interesting. In addition to its main text, the volume presents maps, genealogical tables and numerous photographs, reflecting information gathered by the author in Italy, Spain and England (and even in the United States). Her research took her from the tiny town in Navarre where Margaret was born to the locality in Sicily where the queen died, and a lot of places in-between. The author's keen knowledge of history and her mastery of Italian, Spanish, French and Latin aided her in following every step of Margaret's journey. If you could travel back in time to the twelfth century, Ms Alio would be the perfect guide, and in this book she guides you through an eventful life in a perilous age. Chapters detail Margaret's life but also her world, from Pamplona to Palermo. The chapter on Monreale's splendid abbey, erected on the orders of Margaret and her son, is a sophisticated guide to this unique place, offering the reader nuggets of information rarely mentioned in travel books. Ten appendices provide information on the chronicles of Hugh Falcandus, Romuald of Salerno and others, along with the rarely-available original text of the Assizes of Ariano, the legal code enacted by Margaret's father-in-law in 1140. There is a chronology and over 400 end notes, and a bibliography with over 200 sources cited. (The book's text was double-blind peer reviewed.) There is much in these pages for the armchair historian but also for the hardcore academic, everything from the analysis of sources to maps of medieval Palermo. The 'back matter' containing notes, appendices and the detailed bibliography is longer than the main narrative text. Closer to our times, Palermo-based Jackie Alio stands out as the only Sicilian woman writing books in English about the women of medieval Sicily. She lives and breathes Sicilian history. Her previous titles include The Peoples of Sicily: A Multicultural Legacy and Women of Sicily: Saints, Queens and Rebels. She has published papers on the Jews of medieval Sicily and she co-authored a book on the history of Sicilian cuisine. This biography is the longest academic monograph written in English by a Sicily-based historian.
