What is the period of warfare and disorder in Greece known as?

The period of warfare and disorder in Greece is known as the "Dark Ages," which lasted roughly from 1100 to 800 BCE. This era followed the collapse of the Mycenaean civilization and was characterized by a decline in population, the loss of writing, and the fragmentation of social and political structures. It was marked by increased warfare among small communities and the eventual emergence of city-states, setting the stage for the later Archaic and Classical periods of Greek history.
