Some of the most ancient human civilizations were made around the Mediterranean Sea, so it has had a large influence on the history and ways of life of these cultures. It provided a way of trade, colonization and war, and was the basis of life (like fishing and catching other seafood) for many communities throughout the ages. The combination of similarly shared climate, geology and access to a common sea has led to lots of historical and cultural connections between the ancient and modern societies around the Mediterranean.
