Armed with the Rudd Concession, in 1889 Rhodes obtained a charter from the British Government for his British South Africa Company (BSAC) to rule, police, and make new treaties and concessions from the Limpopo River to the great lakes of Central Africa. He obtained further concessions and treaties north of the Zambezi, such as those in Barotseland (the Lochner Concession with King "Lewanika" in 1890, which was similar to the Rudd Concession); and in the Lake Mweru area (Alfred Sharpe's 1890 Kazembe concession). Rhodes also sent Sharpe to get a concession over mineral-rich Katanga, but met his match in ruthlessness: when Sharpe was rebuffed by its ruler "Msiri", King Leopold II of Belgium obtained a concession over Msiri's dead body for his Congo Free State.
