“. . . this trade in Hell, this open sore of the world . . .”
David Livingstone’s first book, Missionary travels and researches in South Africa, published in 1857, was a huge success, not only because of the harrowing adventures it related but because it alerted the British public to the existence of the Arab slave trade flourishing along Africa’s east coast. The book, along with Livingstone’s many lectures and letters, provoked a call for action once again, and finally, in 1873, a few weeks after Livingstone’s death, Parliament outlawed this trade, too (the West Coast trade had been outlawed in 1834). The Royal Navy sent ships to Africa to enforce the ban.
One of them was H.M.S. “London.”
A few years later, in 1880, while patrolling the the waters off the coast of Tanzania, the London intercepted another dhow and took its cargo aboard. The slavers may have picked up their merchandise at Kilwa, a Portuguese port on the coast of Tanzania, intending to deliver it to the huge weekly slave market on Zanzibar.
Captain G. L. Sulivan, the commander of H.M.S. “Daphne,” another slave-chaser, wrote
The deplorable condition of some of these poor wretches, crammed into a small dhow, surpasses all description; on the bottom of the dhow was a pile of stones as ballast, and on these stones, without even a mat, were twenty-three women huddled together—one or two with infants in their arms—these women were literally doubled up, there being no room to sit erect; on a bamboo deck, about three feet above the keep, were forty-eight men, crowded together in the same way, and on another deck above this were fifty-three children. Some of the slaves were in the last stages of starvation and dysentery.
What would have been in store for all these “poor wretches?” The men might have been sent to work French plantations on Mauritius or Reunion or even held on Zanzibar to work the vast clove plantations there. Or they might even have wound up in Brazil, which didn’t outlaw the slave trade until 1888. The women and children might been taken up the Red Sea to markets on the Arabian Peninsula or over to the Persian Gulf and access to markets in the Near East—in Turkey, Persia, Mesopotamia—where the demand was for concubines and household help. There was a market in these countries for eunuchs, as well. “While Europe and North America were increasingly responding to the dictates of industrial capitalism, and the humanitarian climate and political exigencies of their own milieu, the Arab world was marked by mercantilism, labor-intensive enterprises, and the harem culture.”
The Arab Slave Trade peaked in the 18th and 19th centuries, but it began in the 8th century with the Arab invasion of north Africa and extended into the first decades of the 20th century. There were three main branches. The trans-Saharan route ran from northern Nigeria or Timbuktu to Tunis or Tripoli, carrying gold, ivory, and slaves seized from sub-Saharan, unconverted (non-Islamic) communities—an estimated 3.5 to 4 million over a 12-century period.
Another route ran along the shores of the Red Sea carrying slaves from Muslim kingdoms in southern Sudan and the Christian kingdom in Ethiopia to Red Sea ports. At the end of the 18th century, Darfur was sending 5,000 to 6,000 slaves a year along this route. One scholar guessed that between 12 million and 15 million passed through Cairo in the 16th century.
Finally, the Indian Ocean route began on the east coast and ended at ports on the Persian Gulf, transporting slaves to the Arabian peninsula and the Middle East, with some going to India and even Indonesia or China.
How many slaves did the Arab trade account for between the 8th and 20th centuries? Impossible to say, given the absence of records for most of the period. Estimates by scholars range widely from over 8 million to 25 million. For comparison, the Atlantic trade, which flourished between the 16th and 19th centuries, is said to have involved 12.5 million slaves.
