Why no mention of the very significant Middle Eastern slave trade in history of the entire world, other than the obscure little bit about the Sultan of Oman moving to Zanzibar?
one thing i found out when doing that video is that the 'entire world' is actually so so so so so large that even just to mention only the most hugely hugely hugely significant things, it would take many many many years to even just learn all of those things not even including making a video about it. so at some point i had to come to terms with the fact that i could either abandon the project entirely, or go through in a ridiculous manner and leave out 90% of history, and hopefully at least get some brownie points for at least attempting such an audacious task
