Seems to be a popular topic.
Historian Eric H. Cline has multiple books citing this time period, specifically 1117 BCE as the inflection point for the bronze age "collapse", defined by a deterioration of international shipping routes that weakened the nation-states of the era. I've learned about it recently because YouTube began recommending videos about it.
For example: https://youtu.be/choxcHXhZhE?is=t5lDwQQpqPsE2k5M
One historical event that Cline focuses on is a severe centuries-long drought. It's something the ACOUP article seems to omit. Cline does not focus as much on destruction of bronze-age sites although there is one port city in particular which is linked to the international trade of the time. Exactly who destroyed it appears to be a mystery but it could be linked to the migration theory that ACOUP dismisses. The migration may have actually come as a result of the previously mentioned drought.
The Bronze Age was the third best age.
Beware the Sea Peoples
There's a Portuguese saying "há mouro na costa" which is literally "there are moor at the coast" and means that there is something fishy going on.
The Moors existed about 1900 years after the Sea People of the Bronze Age.
In an alternate timeline, The Sea Peoples are Romans sailing to England, the Anglo-Saxons, the Normans. Things became fuzzy when the English themselves became other civilization's Sea Peoples.
I would wager that almost every civilization has been some other civilization’s sea people at some point in it’s history.
The drought explanation seems particularly plausible for the Hittites. IMO. They had grain storage, but ~3 years of drought would exhaust that. So if the climate becomes just a bit drier the chance of such a three year run increases enough to likely crash their society.
Today we have a huge buffer from the large use of grain to feed animals. In a crisis it could be diverted as human food, with some effort. Large geographic range from global shipping also smooths out blips. Still, a Toba-like eruption would be bad news.
It's unlikely that rich countries would experience famine as severely as poor ones and consequently they would probably still demand meat. Grain that could feed people would still feed livestock.
A draw down of animal stocks increases meat supply in the short term. As grain gets more expensive, farmers sell animals for meat rather than keeping them to reproduce.
Shameless plug for my favourite YouTuber of all time https://youtu.be/aq4G-7v-_xI?si=GviYcvEtOAJ1mln7
I don't think Bret (the author of ACOUP) omits drought - he leads his section on plausible theories with "period of drying and consistent crop failures". While Bret dismisses the out to in migration/invasion theory, he does support the idea of intra-region migration/warfare (perhaps induced by drought/crop failures).
The fantastic Fall of Civilizations podcast also had an episode about it: https://fallofcivilizationspodcast.com/2019/01/21/episode-2-...
Ha, beat me too it. FoC is a great channel.
Eric Cline has an interview on "Tides of History" podcast.
