Livingstone is known as "Africa's greatest missionary," yet he is recorded as having converted only one African: Sechele, who was the chief of the Kwena people of Botswana (Kwena are one of the main Sotho-Tswana clans, found in South Africa, Lesotho, and Botswana in all three Sotho-Tswana language groupings). Sechele was born in 1812. His father died when Sechele was 10, and two of his uncles divided the tribe, which forced Sechele to leave his home for nine years. When Sechele returned, he took over one of his uncle's tribes; at that point, he met Livingstone.
