About Yeke Kingdom

The Yeke Kingdom of the Garanganze people in Katanga, DR Congo, was short-lived, existing from about 1856 to 1891 under one king, Msiri, but it became for a while the most powerful state in south-central Africa, controlling a territory of about half a million square kilometres. The Yeke Kingdom also controlled the only trade route across the continent from east to west, since the Kalahari Desert and Lozi Kingdom in the south and the Congo rainforest in the north blocked alternative routes. It achieved this control through natural resources and force of arms—Msiri traded Katanga's copper principally, but also slaves and ivory, for gunpowder and firearms—and by alliances through marriage. The most important alliances were with Portuguese–Angolans in the Benguela area, with Tippu Tip in the north and with Nyamwezi and Swahili traders in the east, and indirectly with the Sultan of Zanzibar who controlled the east coast traders.
