This is a bit off the beaten track, but I was reading a really interesting article the other day about Albania's modern blood feuds. Since the fall of communism, the resurgence of adherence to the ancient law of the Kanun - a 500-year old medieval code of conduct - has meant that up to an estimated 800 children and 1500 families are caught up in blood feuds. The male children of families can only find sanctuary in their own homes and they remain virtual prisoners for as long as it takes for the feud to be resolved. Here's a clip about it.
