Connecting Europe, Asia, and Africa, the Mediterranean Sea has been for millennia the place where religions, economies, and political systems met, clashed, influenced and absorbed one another. In this brilliant and expansive book, David Abulafia offers a fresh perspective by focusing on the sea itself: its practical importance for transport and sustenance; its dynamic role in the rise and fall of empires; and the remarkable cast of characters-sailors, merchants, migrants, pirates, pilgrims-who have crossed and re-crossed it.
