The document provides a summary of the history and people of Botswana. It describes how the Bush people were the original inhabitants, followed by the Hottentots and Bantu speakers around 2,000 years ago. The Shona speakers settled in the northeast in the 10th century and the Tswana settled in the southeast in the 15th century. By the 18th century the Tswana were well established. In 1820, various clans began forming nations along the Botswana-South Africa border due to pressures from the Zulu and Boers.
