Trans-Saharan Trade

Trans-Saharan trade refers to the long-distance commercial exchange that moved goods, people, and ideas across the Sahara Desert, linking the savanna and forest zones of West Africa (the Sudan and Bilad al-Sudan in Arabic sources) with the Maghreb, Egypt, and the wider Mediterranean and Middle Eastern economies.

While limited exchange existed in antiquity, the trade expanded dramatically after the introduction of the dromedary camel to North Africa in the early centuries CE and the spread of Islam across the Maghreb from the 7th century onward. By the 8th and 9th centuries, regular caravan routes connected termini such as Sijilmasa (in modern Morocco), Ghadames, and Cairo with southern hubs including Awdaghust, Timbuktu, Gao, and Kano.

The principal commodities moving north were gold (from the Bambuk, Bure, and later Akan fields), enslaved people, ivory, kola nuts, and leather. Moving south were salt (mined at Taghaza and Taoudenni), copper, horses, textiles, books, and manufactured goods. Salt-for-gold exchanges were the trade's structural backbone.

The commerce underwrote the rise and prosperity of successive West African states, including the Ghana Empire (c. 700–1240), the Mali Empire (c. 1235–1600s), and the Songhai Empire (c. 1430s–1591). Mansa Musa's pilgrimage to Mecca in 1324, which reportedly destabilized gold prices in Cairo, illustrates the scale of bullion flows. The trade also carried Islam, Arabic literacy, and legal traditions into the Sahel, fostering scholarly centers such as Timbuktu's Sankoré.

Decline set in after the Moroccan Saadian invasion of Songhai in 1591 and accelerated with the rise of Atlantic maritime commerce, which redirected West African exports toward European coastal forts. French colonial expansion and railways largely displaced caravan traffic by the late 19th century, though limited salt and date caravans persisted into the 20th century.
