Having established a beachhead on the lower Congo, in 1883 Stanley set out upriver to extend Leopold's domain, employing his usual methods: negotiations with local chiefs buying sovereignty in exchange for bolts of cloth and trinkets; playing one tribe off another; and if need be, simply shooting an obstructive chief and negotiating with his cowed successor instead. However, as he approached Stanley Falls at the junction between the Congo proper and the Lualaba (close to the general vicinity of Central Africa where he had found Livingstone six years before), it soon became clear that Stanley's men were not the only intruders.
