The collapse that was the Roman empire, especially after it went plutocratic theocratic fascist after being simply plutocratic fascist, is a case in point.

Dark Macedonian ("Hellenistic") another example. Dark Age of Greece ~ 1000 BCE, another. Collapse of Mayas, an even more spectacular case. Collapse of Crete, too.

And then, of course, there is what happened to what was long the richest and most civilized region of the world, the Middle East.
