What gave Rome it’s preeminent power in the ancient world? No doubt its legionnaires were feared from Iberia to Galcantray. To fund military might the descendants of Romulus engaged in prolific international trade. Today, as globalization and international trade spark heated debates in capitals around the world, it is important to remember the long history of trade. From the Chinese to the Phoenicians, the Spaniards and the Dutch, the mighty British empire and the American industrial powerhouse, trade has been at the center of every great power in history. Great powers can either take that which they need by force, or buy it away. To most, trade is clearly preferable.
