A region of informal power
In the 19th century, the Red Sea coast of Sudan was a contested and loosely governed space. The Ottoman Empire and its nominal vassal, the Khedivate of Egypt, claimed authority, but their control was often theoretical. At the same time, the British Empire exerted growing influence, seeking to secure its trade routes to India, which intensified after the Suez Canal's opening in 1869. This created seams and gaps in imperial control, allowing semi-independent port towns to thrive.
The port of Suakin is the most prominent example. Its merchants built a city directly from the sea, quarrying coral blocks from nearby reefs to construct multi-story houses. This "Red Sea style" architecture featured flat roofs to catch sea breezes and elaborate wooden lattice windows called mashrabiyas, which provided both ventilation and privacy. These were ports of call; they were sophisticated urban centers that operated on their own terms. They facilitated a massive trade in goods that evaded imperial customs and regulations, dealing in ivory, gum arabic, and ostrich feathers alongside their most profitable commodity: enslaved people.
The mechanics of the human trade
The Red Sea slave trade is one of the longest and most continuous trafficking systems in history. During the 19th century, these Sudanese ports became major hubs. Caravans, often organized by nomadic peoples like the Beja, moved people captured in the interior of Sudan, Ethiopia, and the Great Lakes region to the coast. The majority of those sold were in their teens, with a high ratio of females destined for domestic service or harems in the Arabian Peninsula, Egypt, and the wider Ottoman Empire.
Estimates suggest that during its 19th-century peak, around 500,000 enslaved people were exported through the Red Sea. The journey was brutal; captives were marched overland, often in chains, to ports like Suakin. From there, they were packed onto dhows for the sea crossing.
Britain's attempts to suppress the trade were complicated. The 1877 Anglo-Egyptian Slave Trade Convention officially outlawed the transport of enslaved people in Egyptian territories, including Sudan. British naval patrols were established in the Red Sea, with the authority to search Egyptian vessels. The long coastline with its many hidden inlets made enforcement difficult. The trade simply moved into deeper shadow, relying on smaller, unofficial harbors and the complicity of local traders who profited from the gray market, ensuring the practice continued long after its official prohibition.
