This podcast on the history of the Byzantine Empire is amazing and that it is available free on the internet speaks well for the future. It focuses on 12 rules and effect on the empire.
The quality is amazing and the depth of information is incredible. For me it is a little dense and could have used a slightly slower pace so I could better absorb the information but other wise this is a college coarse in MP3 format. I feel I deserve credit just for listening to it.
If you have any interest in history or Byzantine, which I have both, you must give this project a listen.
