" Justinian’s reign destroyed the Roman world." and "his ambitions enfeebled the state he tried to restore and the future he bequeathed to Europe was one of poverty and schism."
Seems like a pretty harsh assessment. Empires acquire territory, that's why they're called empires. If you get kicked out of some place you try to take it back.
The Eastern Empire continued on for another 900 years or so which is pretty good for a "destroyed" world. Europe? As in France, Spain, Italy, the British Isles? Justinian bequeathed poverty and schism to that Europe?
