The style and culture of a Bantu people who live chiefly in Botswana and western South Africa, and who speak or are descendants of those who traditionally spoke the Tswana language (formerly considered a dialect of the Sotho language). The Tswana states of the Ngwaketse, Kwena, Ngwato, and Tawana were reconstituted in the 1840s after the wars ended. To refer in general to the style and culture of the inhabitants of the modern nation of Botswana, use "Botswana (national)."
