East Africa’s Rift still anchors debates on human origins
East Africa names the continent’s eastern edge—eighteen UN-listed states and four territories in one scheme, or a narrower Kenya–Tanzania–Uganda core shaped by British administration. Coastal plains rise to cooler highlands; climates run oddly arid for equatorial latitudes until southern moisture returns.
Under the UN statistics scheme the region reaches from the Horn in the north to South-Eastern Africa in the south, with the Great Lakes on its western side and the Indian Ocean coast on the east. Cyclones from the North Indian Ocean strike near the Horn, and South-West Indian Ocean storms hit the south. Wild swings between drought and flood in the twentieth century caused food shortages and pushed people to migrate.
Dry highland areas such as the Rift Valley have yielded some of the oldest traces of human ancestors, which is why the region is often called humanity's birthplace. Bantu-speaking peoples moved in between 2,500 and 3,000 years ago and came to dominate the population. Sea links to Arabia and India mixed cultures along the coast and produced the Swahili trading world, whose language borrowed many Arabic words. Cushitic speakers live in the Horn, and Nilotic peoples make up much of South Sudan.
Portuguese outposts came first after European exploration, followed by British and German colonies. The population passed 537.9 million by a 2017 estimate. Tanzania, Kenya and Ethiopia have some of the biggest economies, and although farming still employs many, the region grows at about 6 percent a year, faster than the rest of Africa, led by Rwanda, Uganda, Kenya and Tanzania.
The Horn, meaning Djibouti, Eritrea, Ethiopia and Somalia, is often treated as its own bloc. The East African Community groups Kenya, Tanzania, Uganda, Rwanda, Burundi, South Sudan, Somalia and the DR Congo. Offshore island states and territories include Seychelles, Mauritius, the Comoros, French-run Réunion and Mayotte, and the small Scattered Islands. Parts of Mozambique and Madagascar share Indian Ocean ties with the region, and Sudan is sometimes counted because of its African Union and COMESA links.
