IN MEDIEVAL ENGLAND, MAN WAS THE RULER OF WOMAN, AND THE KING WAS THE RULER OF WOMAN, AND THE KING WAS THE RULLER OF ALL. HOW, THEN, COULD ROYAL POWER LIE IN FEMALE HANDS? In SHE-WOLVES, celebrated historian Helen Castor tells the dramatic and fascinating stories of four exceptional women who, while never reigning monarchs, held great power: Matilda Eleanor of Aquitaine, Isabella of France and Margaret of Anjou. These were the women who paved the way for Jane Grey, Mary Tudor and Elizabeth I - the Tudor queens who finally confronted what it meant to be a female monarch.
