How similar (~similarly historically biased) is the story of bronze-age-collapse Dark Ages though?
That one is based primarily on the even flimsier evidence of "fewer texts and large human settlements recovered by archaelogists => less literacy and commerce => less culture => dark ages"! Horror! Boo!
How about "people got fed up with the rigid social system and corruption and slavery and massacres, and once a cause materialized (natural disasters, famine), gladly revolted en-masse and destroyed the ruling class, their BS palatial "economy", temples, palaces, scribes, clerks, priests and everything they stood for… including writing"? "Mysterious Sea Peoples" followed by "Dark Ages" my ass.
