Sotho people
They broke away from Swaziland around the year 1540. From mainline Swazi, Batau settled at Wakkerstroom and then Seokodibeng around 1624, at a place that is now called Lake Chrissie. From Lake Chrissie (Seokodibeng) they went to Mokwena River (which today is called Crocodile River) settling there in the late 17th century. Here the Batau established themselves as a nation outside the mainline Swazi and subsequently broke away from all Swazi identity - they shed their Swazi outlook and adopted new ways and customs especially those of the Mapulane, Tswana people and Sotho people.
