We do not know what brought the Greek Dark Ages about. There is a link to an article below that discusses it.
In the European Dark Ages, there was a time of very little writing in the Byzantine Empire that lasted from about 630 to about 750 AD. This happened because peoples' attention was taken up by the spread of Islam and the military actions that entailed.

The collapse of Greek civilization during the Dark Ages (circa 1100-800 BCE) can be attributed to a combination of factors, including the invasion of the Dorian Greeks, which led to widespread destruction and the disruption of trade networks. This period saw a significant decline in population, agricultural production, and literacy, resulting in the loss of cultural and technological advancements. Additionally, the fragmentation of political structures into smaller, isolated communities hindered recovery and stability. Overall, these factors contributed to a prolonged period of socio-economic decline and cultural stagnation.
Roughly from the 8th to 6th century BC, until the beginning of the middle ages, approximately in the 5th century
The period in time that followed the dominance of the Minoans and Myceneans was called the Dark Ages.
The first civilization of Greece on the mainland was the Mycenaean civilization, which emerged around 1600 BCE. It was primarily located in the Peloponnese region, with key sites such as Mycenae, Tiryns, and Pylos. The Mycenaeans are known for their advances in architecture, art, and trade, as well as their influence on later Greek culture. Their civilization eventually declined around 1100 BCE, leading to the Greek Dark Ages.
The dark ages, otherwise known as the middle ages, was followed by the Renaissance era. During the renaissance, Europe began to re-adopt old Greek and Roman philosophies, art, and science.
All information in the dark ages were based on advances by the ancient Greeks.
