The Tswana migrated from East Africa to central South Africa in the 14th century. They are closely related to the Sotho of Lesotho and South Africa, and the two groups share language and customs. They claim a common ancestor, the Mogale, and share an agrarian culture, social structures, political organization, religious and magical beliefs, and family life. The Sotho and Tswana languages are all inherently intelligible, but for political and historical reasons are usually considered three.
