I watched this episode a week or so ago. It’s fascinating.
The entire series - which began as a podcast - is very nicely done. Roman Britain, the Vikings in Greenland, the Khmer Empire, Sumeria, the Mayans... I highly recommend it.
Since I have been “working” from home for the last six months due to COVID, I’ve had the ... ah, opportunity to check out dozens of history documentaries on YouTube.
This is a very good series.
The Songhai was so interesting, tho, I watched it all the way through! The author has done a really fine job explaining the series of events that caused west Africa to 'crack like an eggshell,' and why Portugal disappeared off the world stage at the height of their own empire, both never to recover.
Feeding the mind sure beats watching re-runs of America's Funniest Bloopers :)
