The ancient Greek city-states (polis), such as Athens and Sparta, developed between 700 BCE to 400 BCE in a region influenced by mountainous terrain and extensive coastlines that encouraged trade.

The Roman Republic and Empire later dominated the region politically and culturally from the 6th century BCE to the 4th century CE.
