Which early civilization brought a Dark Age to Greece?

The Greek Dark Age is the interval between the collapse of the Mycenaean civilization, around 1200 BCE, and the Greek Archaic Period, around c. 800 BCE.

The Classical Age came centuries after two earlier civilizations, the Minoans and the Mycenaeans, flourished and then vanished, leaving the Greeks in a period later called the Dark Age of Ancient Greece. The Minoan culture developed on Crete, an island southeast of the Greek mainland as early as 2700 BCE.
