The Basotho are a Bantu ethnic group whose ancestors have lived in southern Africa since around the fifth century. The Basotho nation emerged from the accomplished diplomacy of Moshoeshoe I who gathered together disparate clans of Sotho–Tswana origin that had dispersed across southern Africa in the early 19th century. Most Basotho today live in South Africa, as the area of the Orange Free State was originally part of Moshoeshoe's nation (now Lesotho).
