The codfish. Wars have been fought over it, revolutions have been spurred by it, national diets have been based on it, economies and livelihoods have depended on it, and the settlement of North America was driven by it. To the millions it has sustained, it has been a treasure more precious than gold. Indeed, the codfish has played a fascinating and crucial role in world history.Cod spans a thousand years and four continents. From the Vikings, who pursued the codfish across the Atlantic, and the enigmatic Basques, who first commercialized it in medieval times, to Bartholomew Gosnold, who named Cape Cod in 1602, and Clarence Birdseye, who founded an industry on frozen cod in the 1930s, Mark Kurlansky introduces the explorers, merchants, writers, chefs, and of course the fishermen, whose lives have interwoven with this prolific fish. He chronicles the fifteenth-century politics of the Hanseatic League and the cod wars of the sixteenth and twentieth centuries.
