The BaNambya came from Great Zimbabwe, and conquered some Kalanga tribes along their way to Hwange, Victoria Falls and the north-eastern parts of Botswana, which changed the Nambya language and made it similar to TjiKalanga.
The BaNambya were being led by a subchief of the Great Zimbabwe by the name of Denderende Sawanga and went to present day Dete which is where they settled.
This is proven by the stone structures that were built by the Nambya that are similar to that of Great Zimbabwe.
The BaNambya originated from the Rozvi empire of Masvingo Great Zimbabwe.
