A GREAT subject. I'd heard about these raids before; didn't know there was a specific book dedicated to it.
All too often talk of 'slavery' only is about the trans-atlantic trade of Africans, which was big, to be sure, but the amount of Europeans that ended up in the Middle-East (through the Barbary States, as you point out) was very large as well.
Looking forward to more from you.
