This is an unlisted video of a lecture given in November 2022. It covers the reign of the Empress Irene and her part in the slow recovery of Byzantium after 717 to become once more the greatest power in the Mediterranean World. It is unlisted, unlike the other lectures on this site, because it will eventually be edited into a series for publication elsewhere. If you have enjoyed this lecture, its author might enjoy a bag of coffee, or some other little token of esteem: https://www.amazon.co.uk/hz/wishlist/…
