 When Babirwa moved into the area which is today known as Gwanda, it was inhabited by Jahunda (Kalanga dialect) speaking people and a group of Ndebele who moved southward from the Northern side of precolonial Matabeleland South Province which they invaded under their leader Mzilikazi coming from Transvaal, South Africa by the way of Southern Botswana, running away from the Boers in Transvaal after running away from Shaka in Natal.Other group of Babirwa left Bobirwa and with other Transvaal migrants again and joined their relatives who left Transvaal for Bokgalaka, what Sothos called Zimbabwe back then

Not all Basotho of Zimbabwe are Babirwa.The Sothos that are found under Beit Bridge district all the way to Manama and surrounding areas are not Babirwa.
