Engineering an Empire: The Byzantines

       This is an interesting video from the History Channel about the Byzantine Empire (you can select the automatically generated subtitles on YouTube).
        I'm going to ask some volunteers to explain the most important events in that video (each student only has to explain one of them). You can also tell us the different mistakes you have found in the subtitles.
        It is not a compulsory activity, but I think it will be useful for you and it will improve your final mark.
