The salt trade refers to the exchange of salt, a vital mineral used for preserving food and enhancing flavor. Historically, salt was highly valued, often referred to as "white gold." It played a crucial role in various economies, especially in regions where fresh food was scarce. Major trade routes developed, connecting salt-producing areas to markets where it was in high demand. In ancient times, cities like Rome and Carthage relied on salt for food preservation and trade. The Sahara Desert was a significant source of salt, with caravans transporting it across vast distances. This trade not only influenced local economies but also shaped cultural exchanges between different societies.
