Just fyi, this is not intended to be one of my hardcore scholarly posts, and it has been quite a few years since I’ve looked deeply into these issues. This response is more like I’m your quirky grandma pounding wine over lunch.
So, the Sea Peoples. You know how when you’re younger you think it was The
Barbarians who caused Rome to Fall in 476, but then you get older and
eventually learn that the “Barbarians” were actually hardcore Romanized and a
massive empire can’t just fall in one year because of one group of icky
outsiders anyway? Well, the “Sea Peoples” are to the Bronze Age Collapse as the “Barbarians” are to the Fall of Rome.
The Eastern Mediterranean Empires of the Late Bronze Age were a series of highly cosmopolitan, internationalized, and interconnected economic and political system ranging from Ancient Greece, to Asia Minor, to Egypt, to Sumeria. Complex systems like
that take a long time to build up, and require a lot of little problems building up over a span over the course of years to cause a widespread collapse. And when we say
“collapse” I think it’s incorrect to think of just cities being destroyed. By “collapse” I
mean the breakdown of international trade routes and economic systems and
systems of communication.
So as for what actually happened. We have primary resources; a lot in fact. We have a rich archaeological record, linguistic evidence, not to mention evidence from
geologists and climatologists. But these pieces of evidence tell a lot of little stories which only together could form a situation in which all that infrastructure could totally break down.
There were climate related problems; droughts, for example, unusual flooding patterns. There was unusually heavy volcanic and seismic activity. Some of the trade routes were impacted by these natural occurrences, causing minute snafus over a variety of interconnected economic systems, leading to a lot of big economic snafus over time. Empires were dealing with civil unrest and rebellions, undoubtedly partial results of the earthquakes and droughts and economic issues.
Though I’m primarily speaking of Sumeria and the Eastern Mediterranean, the Western and Central Mediterranean were hardly isolated from these economic and natural incidents, and these dominant international systems. Peoples of the West and Central Mediterranean responded to these disruptions by migrating east to the great imperial centers, which where all lowkey already breaking down.
These migrants, the “Sea Peoples,” likely settled and assimilated into into the civilizations they are purported to have destroyed. Some, I’m sure, were met with hostility upon their arrival. Others wanted to relocate politically and engaged in warfare, and others still wanted to plunder these slowly failing economies for all they were worth. So really, the “Sea Peoples” were multiple groups of migrants from dispersed areas migrating to a massive geographical area in a series of waves in response to a widespread set of structural problems. Meaning, that they were reacting to a set of pre-existing problems, not causing them.
Also, a lot of archaeological and linguistic evidence points to the “Sea Peoples” being of Etruscan and Aegean descent and I can’t tell you how much that thrills me.
