🟢 ARAB SLAVE TRADE 1/2
The “Arab slave trade” is a modern umbrella term for several overlapping slave systems run for centuries by Arab, Berber, Swahili, Ottoman, and other Muslim merchants and states.
It moved people from sub-Saharan Africa (the largest documented flow), the Balkans, the Black Sea, the Caucasus, and Europe into North Africa, the Middle East, the Arabian Peninsula, Persia, and India.
Slavery itself predated Islam in Arabia and the Sahara; Islamic law later regulated it (permitting enslavement of non-Muslims captured in war or purchased) rather than inventing it.
Exact numbers are estimates because records are fragmentary and mortality on desert and sea routes was high.
Scholarly ranges for Africans taken across the Sahara, Red Sea, and Indian Ocean from the 7th to the early 20th century commonly fall between 10 and 18 million, with additional millions of Europeans, Slavs, Circassians, and others.

🟢 Pre-Islamic and 7th century
Ancient Egypt already raided Nubia for slaves.
Trans-Saharan networks existed under the Garamantes.
After the Muslim conquest of Egypt (640s), the 651/652 Baqt treaty with Christian Nubia (Makuria) required an annual tribute of roughly 360–400 slaves in exchange for goods and non-aggression.
The arrangement, unique in early Islamic expansion, lasted in some form for centuries.

🟢 8th–9th centuries
Caliphal expansion and demand for agricultural labor, domestic servants, concubines, and soldiers increased imports.
East African (“Zanj”) slaves were used to reclaim salt marshes near Basra.
In 869–883 the Zanj Rebellion, led by Ali ibn Muhammad, became one of the largest slave revolts in history.
Rebels seized cities, minted coins, and held southern Iraq for years before the Abbasids crushed them.
Casualties were in the tens or hundreds of thousands.

🟢 Medieval period (10th–15th centuries)
Trans-Saharan caravans (gold, salt, slaves) and Red Sea/Indian Ocean shipping became regular.
Slaves included West Africans, Sudanese, Ethiopians, and East Africans, plus “Saqaliba” (Slavs and other Europeans) funneled through Viking, Khazar, and Balkan routes.
Female slaves were often preferred for households and harems; many males were castrated (eunuchs), a procedure with high death rates.
Mamluk military slavery drew heavily on Turks, Circassians, and later Africans. Demand rose as local sources of slaves declined.

🟢 16th–18th centuries
The Barbary corsairs of Algiers, Tunis, Tripoli, and Morocco raided European ships and coasts from Italy to Iceland.
Historian Robert C. Davis estimated 1–1.25 million European captives between roughly 1530 and 1780 from the main Barbary ports alone (figures exclude Morocco and earlier centuries).
Many were ransomed; the poor remained enslaved.
The trade declined after European naval pressure and ended as a large-scale system with the French conquest of Algiers in 1830.
Parallel Black Sea and Ottoman trades continued.

🟢 19th century peak in East Africa
Omani Arabs made Zanzibar the hub of the Indian Ocean trade and clove plantations.
Tens of thousands of slaves arrived annually from the mainland in peak decades; estimates for the 19th century alone run into the hundreds of thousands to over a million exported or retained locally.
British treaties (Moresby 1822, Hamerton 1845, Frere 1873) first restricted then banned the export trade and closed the Zanzibar market.
Slavery itself was decreed abolished in Zanzibar in 1897, though enforcement lagged until 1909.
The Ottoman Empire restricted the African slave trade in stages from the 1840s–1880s.
Tunisia abolished slavery in 1846, unusually early.
