The Rise and Fall of the Empire

The West is in decline. It's fragmented. The Empire has now broken up into petty kingdoms and tribal territories. Latin started to be displaced by Greek. So there was an effort in Justinian's crazy mind that he was going to reclaim all of what had been lost to the barbarians. But my point is, why did the East do that? And there's a lot of explanations,. as I said, but the second question about all of these invasions in rise and fall is it's a very existential one.
