Why did the Greeks over populated?

The Greeks experienced overpopulation due to a combination of factors including limited arable land, agricultural advancements that increased food production, and a rise in trade and commerce that led to population growth. As city-states expanded, they faced pressure on resources, prompting colonization and the establishment of new settlements across the Mediterranean and Black Sea regions. This movement helped alleviate overcrowding in mainland Greece and allowed for the spread of Greek culture and influence.
