An enduring historical myth is that women through the ages have played a minor role and have had a limited impact on historical evnts. In Europe during the 13th Century, four beautiful sisters, the daughters of the Count and Countess of Provence, Raymond Berenger V and Beatrice of Savoy, came out of the minor nobility to become queens. Marguerite, Eleanor, Sanchia, and Beatrice became the queens of France, England, the Holy Roman Empire, and Sicily, respectively. At age 13, Marguerite became the bride of the French king, Louis IX, who was dominated by his mother, the White Queen, until her death. Marguerite accompanied Louis IX on his First Crusade which turned into a rout and a disaster. In fact, shortly after giving birth in the Middle East, Queen Marguerite had to raise funds to ransome her captive husband from the Mamluks. Queen Marguerite and her sister, Queen Eleanor of England, were instrumental in persuading their husbands to forge a strong peace treaty between their two countries and the two royal families were emotionally close. Sanchia was married to Henry III's younger brother, Richard, who was one of the wealthest men in Europe. Unfortunately, she was marginalized by her husband and her reign as the queen of the Holy Roman Empire was short. Beatrice inherited all of her father's property which she had to defend from the claims of her sisters and she eventually married Charles, a younger brother of Louis IX. She and her husband, Charles, maneuvered diplomatically, to secure Charles's position as King of Sicily and they had to fight to gain that throne. Unfortunately, Beatrice died not long after being crowned Queen of Sicily. Goldstone draws heavily on primary sources including correspondence among the sisters, their families, and those close to them. She also relies heavily on contempory chroniclers of that period such as Matthew Paris and Jean de Joinville. A highly readable book providing a window into that era of European history.
