The Greek world developed around the Aegean Sea and the wider eastern Mediterranean. Earlier Bronze Age societies, including the Minoans and Mycenaeans, formed important foundations for later Greek civilization.
After the changes that followed the end of the Bronze Age, communities gradually developed into independent city-states known as poleis. These communities shared language, religious traditions and cultural practices while often maintaining separate political identities.
From the Archaic period onward, Greek settlements and colonies spread across parts of the Mediterranean and Black Sea regions.
