Salt (2002)

Mark Kurlansky's sprawling maritime and overland odyssey tracks the only rock humans eat across thousands of years and multiple continents. From ancient Chinese brine wells and Sahara camel caravans to Celtic salt routes and Gandhi's momentous March to Dandi, the narrative shows how controlling this humble mineral forged taxation systems, sparked bloody revolutions, and dictated early global trade routes. It is an exhilarating voyage across geopolitical frontiers that reveals how a daily seasoning shaped the rise and fall of empires.
