On the topic of lectures, I tend to find them a bit dry on occasion so I stick to shorter, more colorful, less historically accurate narrations. So in general I think my favorite types of videos are like this:
Ancient Rome in 20 minutes
Probably helps it's narrated by Brian Cox, the actor. I've always thought he had a great voice.
To put a Chinese/Eastern spin back on it, there's a channel that takes translated historical accounts and puts a voice to them. Here's the translation of a Chinese historian taking the accounts of merchants who had visited Rome and other Western/Eastern empires:
Ancient Chinese Historian Describes The Roman Empire // 3rd century AD "Weilüe" // Primary Source
It's really interesting because he doesn't get too much detail about the structure of the Roman empire but he can name all sorts of products (the things a merchant might be concerned about).
Apologies if it's too far off topic, I'll try to come back and edit/delete.
