By the early Middle Ages, West African and Saharan communities depended on long-distance trade to balance resources: desert salt was vital for diet and food preservation, while Sahelian zones supplied gold and other goods. This broader trans-Saharan system set the economic conditions for specialized salt-mining settlements such as Taghaza and, later, Taoudenni.
In 1068, the geographer al-Bakri described salt mining at a Saharan site called “Tantatal,” located about twenty days from Sijilmasa (a major northern desert-edge market town). Later historians often link this description to the Taghaza salt field, showing that the western Sahara’s salt industry was already well known in written sources by the 11th century.
Around 1275, al-Qazwini mentioned Taghaza (as “Taghara”), describing a settlement where buildings were made of salt and the mines were worked by enslaved laborers. His account also notes that salt was exported south by caravan, highlighting Taghaza’s role as an industrial node feeding West African markets.
In February 1352, traveler Ibn Battuta reached Taghaza after roughly 25 days from Sijilmasa. He described a harsh mining settlement with salt-block buildings and enslaved miners, and he noted how transport costs made salt far more valuable in southern markets. His account is a key firsthand snapshot of Taghaza’s caravan economy at its height.
By 1375, European cartography reflected knowledge of trans-Saharan routes: the Catalan Atlas depicts West African trade networks linking North Africa to the Niger River region. This helps show how widely recognized caravan routes and key waypoints had become, even beyond the Islamic scholarly world that produced many early written accounts.
Salt from Taghaza moved by camel caravan to major southern trade centers such as Timbuktu, where it could be exchanged for gold and other goods. Control of these routes helped support the wealth and political influence of West African states and city networks tied to the Niger River corridor.
Around 1510, Leo Africanus visited Taghaza and emphasized the extreme supply risks of operating a mining town far from food and fresh water. Accounts like his underline a key feature of the Taghaza system: even when the mine site was economically important, it was environmentally fragile and heavily dependent on caravan logistics.
In 1586, Moroccan Saadian forces occupied Taghaza, disrupting the established political control of the salt fields. A major chronicle tradition reports that some miners moved to “Tawdani” (Taoudenni), beginning the shift of large-scale production away from Taghaza.
In 1591, the Saadian army under Judar Pasha defeated Songhai at the Battle of Tondibi, accelerating a major political reordering across the Niger bend. After these events, Taghaza’s position declined further, and Taoudenni increasingly replaced it as the main regional salt producer closer to Timbuktu’s caravan connections.
By the late 16th century, Taoudenni emerged as the primary salt source in the region, replacing the older Taghaza field. The mines’ output was cut into slabs and moved south, linking a remote desert extraction zone to Sahelian cities where salt functioned as a critical commodity and, at times, a form of value in exchange.
In 1828, French traveler René Caillié traveled with a major caravan network north of Timbuktu and noted Taghaza’s ruined salt-brick structures. His journey also reflects the continued scale of caravan transport in the 19th century, even as older nodes like Taghaza had already been eclipsed by newer production at Taoudenni.
In 1906, French officer Édouard Cortier reached Taoudenni with camel troops and published one of the first detailed modern descriptions of the mines. His account documents a fortified building (the Ksar de Smida) and helps anchor how the site functioned as a remote production camp tied to long-distance transport rather than local agriculture.
The semi-annual “azalai” caravans between Timbuktu and Taoudenni remained active into the 20th century, though their scale declined over time. These caravans illustrate continuity of older trade practices even as motor transport began to replace camels on some routes.
In 1969, Mali’s government under Moussa Traoré established a military post and prison at Taoudenni. Prisoners were forced to work in the salt mines, linking the site’s economic function to state coercion and political repression rather than primarily merchant-controlled caravan labor.
The Taoudenni prison was closed in 1988, ending a major chapter of forced labor at the mines. By the late 20th century, trucks increasingly transported salt, while some camel caravans continued as a reduced but culturally significant remnant of the older Taghaza–Taoudenni caravan network.
