For those interested in the politics of 'outremer' etc I found a great site with lots of detailed and informed podcast discussions which I highly recommend. The owners of the site are authors writing 'fictional histories' of the Crusader Kingdom and Principalities but scholars usually appear on the podcasts, Dr so and so and Professor whoever. I highly recommend it for anyone who wants a more detailed understanding of the Crusader states, the personalities and the politics around them: also on You Tube here:
