I thought it was very interesting to hear such a list from someone who's spent so many years telling the historical narrative and interviewing various experts. It was also interesting to see how he limited the list to the years from 476 to 1204.

The list consisted of:

10) Nikephoras II Phokas

9) John I Tzimiskes

8) Romanos Lekapenos

7) Maurice

6) Constantine V (🗿)

5) Heraclius

4) Leo III

3) Alexios Komnenos

2) Basil II

1) Anastasius
