The following video is banned all over the internet, but it’s available on archive, thank fully, though one wonders for how long.
It’s 12 hours long, however, you simply must watch it, as you will learn more history in 12 hours from this well researched documentary, than you did in 12 years of k-12.
Your life will never be the same after watching it.
