Salt: A World History

Mark Kurlansky traces the strange, sprawling history of salt from ancient China to the modern world, showing how a substance now sold for pennies was once so precious that it built cities, financed empires, and triggered revolutions. Because salt was the only widely available way to preserve food before refrigeration, control over its production and trade routes conferred enormous economic and political power, and Kurlansky follows that power as it shifted from Chinese salt monopolies to Roman salt roads to European salt taxes and beyond.

The book matters because it demonstrates, through one unglamorous mineral, how deeply economic necessity shapes political history — wars, taxes, and revolutions that history books usually explain through ideology or ambition often had a salt monopoly or a salt tax quietly underneath them. Kurlansky's method — following a single commodity across millennia and continents — turns something ordinary into a lens for understanding the deep structure of preindustrial economies.

Who should read it

Readers who enjoy history told through the lens of everyday materials rather than kings and battles, and anyone curious how something now nearly free was once worth fighting wars over. It's well suited to food history enthusiasts and readers who liked Kurlansky's other single-commodity histories.
