For obvious reasons, most books on the Crusades have not focused on the role of women. They were definitely not ignored (the stories about Maragaret of Provence's defense of Damietta, Eleanor of Aquitaine joining the Second Crusade, or that anonymous woman who died at the Siege of Acre in around 1190, using her body to fill the ditch, are well known) but we lacked a more in-depth view of their reality, whether they were queens, nobles, simple folks, or whether they went to the Holy Land on their own or accompanying a husband, a brother. Some of them stayed, hoping to see their loved one(s) come back.
Thanks to this book, we now get to understand better the roles that women played during the Crusades. There were many of those: some women helped gather funds, prayed, negotiated for ransoms of captured loved ones, and participated in some military campaigns. The list is long. Unfortunately, the author explains that there is much we don't know and that we probably never will.
Despite this, Nicholson provides us with a good overview in this highly researched book that encompasses the Crusades in the Middle East, Spain, Eastern Europe, and Southern France. There are even some examples on the Muslim side, although those are few and far between.
Regardless, this is definitely a must-have for any avid Crusades history readers like me.
