A long split in the continent from Ethiopia to Mozambique, surrounded by high plateaus and deep basins. Fertile volcanic soils, great lakes, and high elevations create dense settlement pockets and corridors of migration. Southward, the land transitions into broad plateaus—Botswana to South Africa—supporting pastoralism, agriculture, and later centralized kingdoms. Geography here generates layered civilizations: Rift-valley agriculture, Bantu migration routes, cattle cultures, and powerful plateau states that anchor southern Africa.
