The Trans-Saharan Trade Routes
The camel caravan networks that for a millennium carried gold, salt, and other goods across the Sahara, linking West African empires such as Ghana and Mali to the Mediterranean and Islamic worlds, and spreading Islam, literacy, and urban civilization along the desert's edge.
Timeline
The Camel Opens the Desert
The domesticated dromedary camel spread through the Sahara in the early centuries AD, making regular crossings of the world's largest hot desert possible for the first time. Berber-speaking herders and traders established oasis-to-oasis routes, moving gold, salt, ivory, and other goods between the Sahel and the Mediterranean coast.
Location: Sahara Desert
Arab Conquest Regularizes the Caravans
After the Arab conquest of North Africa in the late 7th century, annual trade caravans began crossing the desert on a regular basis, with routes later described in detail by Arabic geographers. The Moroccan entrepot of Sijilmasa, founded around 757, became the main northern terminus for gold flowing toward Al-Andalus and beyond.

Ghana, the Land of Gold
By the 10th century the empire of Ghana controlled the exchange of Sahelian gold for North African salt and manufactured goods. Arab geographers such as Ibn Hawqal described its wealth in the 950s, and the desert towns of Awdaghust and Tadmekka thrived as caravan stops where traders, scholars, and enslaved captives all passed through.
Location: Awdaghust, Mauritania
The Almoravids Disrupt the Routes
The Almoravid movement, which arose among the Sanhaja Berbers controlling the desert routes, seized Awdaghust from Ghana in the 1070s as part of its campaigns. Ghana's dominance over the gold trade eroded in the following century, and new power centers rose further south and east along the Niger River.
Location: Awdaghust, Mauritania
Mali Inherits the Gold Trade
The Mali empire consolidated control of the Bambuk, Bure, and later Akan goldfields and the desert-edge towns of Timbuktu, Gao, and Oualata. The empire taxed and protected the caravans, and Timbuktu grew into a major center of Islamic scholarship, commerce, and manuscript culture sustained by trans-Saharan wealth.
Location: Niger River, West Africa
Mansa Musa's Pilgrimage Stuns Cairo
Mali's ruler Mansa Musa crossed the Sahara with a caravan reported in the tens of thousands on his pilgrimage to Mecca, distributing so much gold in Cairo that chroniclers said its market price was depressed for years. The display fixed West African gold wealth in the European and Islamic imagination for generations.
Location: Cairo, Egypt
Ibn Battuta Crosses the Desert
The Moroccan traveler Ibn Battuta crossed the Sahara in 1352-53 with a caravan and described the journey in detail: guides sent ahead to arrange water, caravans averaging a thousand camels, and the thriving Sudanese trading town of Oualata, where he noted the courtesy of its people and the security Mali's authority provided travelers.
Location: Sijilmasa to Oualata
The Moroccan Invasion of Songhai
A Moroccan army under Judar Pasha crossed the Sahara with firearms and destroyed the Songhai army at Tondibi in March 1591, sacking Timbuktu and Gao. The invasion shattered the largest remaining West African state and destabilized the interior routes, while the armory of arquebuses traveled with the caravan as a demonstration of changed military technology.
Location: Tondibi, Mali
Atlantic Routes Displace the Desert
By the 17th century European sea trade along the Atlantic coast offered faster, cheaper freight than the desert caravans, and much of West Africa's gold and enslaved-labor commerce shifted to coastal ports. The trans-Saharan routes, past their peak since the early 1600s, faded into the smaller regional camel traffic that persists today.
