As far as we are concerned, a book entitled "Crusader Criminals: The Knights Who Went Rogue in the Holy Land," is, obviously, a book to read. To our joy, that book is informed, and readable, and full of Things We Did Not Know. And to our further joy, the author, Steve Tibble, who came to talk to us for this episode, is engaging, deeply informed, and kind hearted, and, of course, full of Things We Did Not Know. In our conversation, we discuss, among other things, the mafia that the Frankish prisoners of war ran in Cairo; the Viking crusade, which involved killing lions in North Africa; the state of the Pilgrim Road that civilian Europeans were using to reach the Holy Land, which had so many slaughtered pilgrims lying on the side of the road that it lead to the Templars getting involved; and the European method of getting rid of outlaws, which was to make them into crusaders. There is yet another saintly pirate, as well, I think our third so far. In our talk and in this book, Steve focuses on the violence that was the foundation of the Crusades -- on all sides -- but also gives his overarching view of the way the Crusades were a result not just of clashing religions, but of climate change and the conflicts between nomadic and sedentary societies. Oh, and by the way, we all agree that it's really a shame that Cormac McCarthy didn't become an historian of the Crusades. And that there are a lot of potential historical novels and movies wandering around in this book. (Link to Steve's website, and information on his books, are in the Show Notes.)
