Margaret of Navarre (1135-1183) stands out as Sicily's greatest medieval queen. As her son's regent for five years, she was the most powerful woman in Europe, ruling a multicultural kingdom of Christians, Muslims and Jews. Her life and times make for the compelling story of a wife, sister, mother and leader. Based on original medieval records consulted during research in Italy and Spain, this is the first biography ever written about Queen Margaret. This abridged edition includes the narrative text of the 512-page print edition of 2017 but without the endnotes. Two of the ten appendices, and most of the maps, are included, along with the genealogical tables and an outline of the bibliography. This book is an excellent introduction to a woman about whom virtually nothing was written until recently.
