I've been on about the Bronze Age Collapse recently. The popular notion is that in the late bronze age the civilizations of the eastern Mediterranean all fell apart quite suddenly.
The Mycenaean Greeks lost their writing entirely, the Egyptians forgot hieroglyphics, cuneiform died out completely. There were invasions of mystery people, governments crumbled, popular uprisings, entire cities wiped off the map.
I couldn't wrap my head around how it all happened so quickly, supposedly in the span of 40 to 50 years.
In my continued searching for answers, I stumbled on this video which challenges the pop history of it all, and clears up ALLOT.
I realized that the concerns felt in our modern era are not without precedent, and thought it worth a share. It's on the long side, but very well organized, and great for while I was sitting down to do taxes last night.
