Sijilmasa: the City of Gold

By Kaveh Hosseini

Before Marrakech, before Fez mattered, there was Sijilmasa — the Saharan entrepôt whose gold financed the Moroccan empire, the richest city of its age that the world has almost forgotten.

Founded in 757 by the Miknasa Berbers on the edge of the Sahara, at the northern mouth of the great caravan routes, Sijilmasa occupied a position of extraordinary economic power: it was the terminus where the gold of the Sudan — from the mines of Bambuk and Bouré, in what is now Mali and Guinea — was exchanged for the salt, cloth, and manufactures of the Mediterranean world. The caravans crossed two thousand kilometers of desert, guided by Berber experts, to reach its gates; the gold they carried became the dinars of the Almoravids, the currency of an empire.

The city's wealth was legendary. The geographer al-Bakri, writing in the eleventh century, described Sijilmasa's markets overflowing with Sudanese gold, its mosques and palaces built by merchant princes, its irrigation making the Tafilalt oasis bloom with dates and henna. When Yusuf ibn Tashfin seized the city around 1055, he captured the financial engine of his empire: Sijilmasa's gold became Almoravid dinars, and Almoravid dinars became the trusted currency of Mediterranean trade — imitated by Christian kings from Aragon to the Crusader states.

Sijilmasa's importance outlived dynasties. The Almoravids held it, the Almohads held it, the Marinids held it; Ibn Battuta passed through it in 1352 on his way to Mali, noting its date palms and its scholars. The Moroccan sultans understood what modern economists sometimes forget: whoever held Sijilmasa held the gold supply of the western Mediterranean, and with it the power to mint, to pay armies, to build.

The end was violence, not economics. In 1393 the city was sacked and destroyed — the chronicles blame tribal wars — and though a smaller settlement survived nearby, the great entrepôt never recovered. The trans-Saharan trade shifted to new routes, the Portuguese caravels began to outflank the desert by sea, and Sijilmasa sank into the sand. Today its ruins sprawl across the Tafilalt near Rissani: kilometers of melted mud-brick walls, the ghost of the richest city of medieval Morocco.

Sijilmasa's lesson is the foundation of Moroccan economic history: the country's imperial power was built on its position as the hinge between two worlds — the gold and slaves and ivory of sub-Saharan Africa flowing north, the salt and manufactures of the Mediterranean flowing south, and Morocco taking its cut as the indispensable intermediary. The Almoravid dinar, the Marinid fleets, the Saadian sugar wealth — all of it flows, ultimately, from the caravans that crossed the desert to Sijilmasa's gates.

The human machinery of the gold trade deserves imagining: the great caravans assembled at Sijilmasa each autumn — thousands of camels, Berber guides who read the desert like a book, water cached at wells along routes known only to the guilds — departing into an ocean of sand for two months, navigating by stars and by the bones of those who failed. The salt came from Taghaza, the "town of salt," where houses were built of salt blocks and the miners were slaves of the desert; a slab of Taghaza salt traded in the Sudan for its weight in gold, the most extreme exchange rate in economic history. Sijilmasa's merchants were the venture capitalists of the age: they financed caravans on profit-sharing contracts — the qirad — that Islamic law had perfected, spreading risk across dozens of investors. When the Almoravids took the city, they inherited not just gold but a financial system: the contracts, the guilds, the assay offices that guaranteed the dinar's purity. The murabitun dinar's fineness — consistently above 90% — was Sijilmasa's real product, and it is why Christian kings from Aragon to Jerusalem imitated it rather than merely stealing it.
