Arab-Islamic slave trade
BLACK AFRICANS IN THE EASTERN SLAVE TRADE
01. THE ROAD TO ZANZIBAR
Men, women and children were captured deep inside Central and East Africa, chained together and forced to walk hundreds of kilometres toward the coast.
One of the best documented routes ran roughly 1,200 km from Ujiji to Bagamoyo, opposite Zanzibar. UNESCO states that many of the slave hunters and traders operating in this region were Arabs. Captives reaching the coast could then be sold onward to Zanzibar, Arabia, Persia and India.
By the nineteenth century, Zanzibar had become one of East Africa's major slave-trading centres. UNESCO records that by the mid-1800s more than 20,000 enslaved Africans were being imported into Zanzibar annually, many destined for the island's clove plantations.
These people were not statistics.
They were merchandise.

SLAVERY DID NOT END AT THE MARKET
02. THE PLANTATION BEHIND THE PALACE
The slave market was only the beginning.
Thousands of captured Africans remained in Zanzibar itself, where enslaved labour became an important part of the clove plantation economy.
UNESCO records that around half of the enslaved people imported into Zanzibar in the mid-nineteenth century were absorbed by local plantations. Others were re-exported toward Kenya, Somalia, Oman and still farther east.
African captives were used as agricultural workers, domestic servants, concubines, soldiers and labourers across parts of Arabia and the wider Indian Ocean world.
UNESCO's General History of Africa documents African slaves in southern Arabia working in households, armies, ports and plantations.
The slave trade was officially prohibited in Zanzibar in 1873 under British pressure, although clandestine trading continued afterwards.
A HUMAN VOICE
Robert Adams, an African-American sailor shipwrecked in 1810, was himself enslaved in North and West Africa before eventually being ransomed. His published narrative describes being repeatedly transferred between owners and markets. Cambridge notes that his story became one of the important nineteenth-century captivity narratives.
