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.

Christian propaganda has highjacked civilization, after Christianity tried its best to destroy it completely.
Why did all the books end up with the Arabs? because the Arabs were dedicated scholars? No. The first book written in (primitive, experimental) Arabic was the Qur'an.
The books of the West ended in the East and South because the Christians destroyed them. Oh, they also destroyed physically the intellectuals, who fled to Persia. To protect them, Persia declared war to Xtian fanatical Rome/Constantinople. That terrible war destroyed both empires, and Muhammad decided to pounce, as is explained in the Qur'an.
And so on...
