In his History of the Peloponnesian WarThucydides points out that piracy preceded commerce as the first economic activity in ancient Greece. Poor agricultural conditions led down-on-their luck villagers to turn their knowledge of their cragged shores and oft-used fishing routes to their advantage to rob. Not only were these practices tolerated, they also seem to have been condoned in places like Cilicia and Lycia, the most notorious pirate havens of the ancient world.
