Barotseland is not Northewestern Rhodesia

I think the map came from serious lack of distinction between Northwestern Rhodesia and a land called Barotseland or its the usual Lozi tricks at it.

One think is for sure, Northwestern Rhodesia had several places included like the Nkoya, Luvale, Lunda and Tonga areas. There is even a reference to that effect here. 

" ... the protectorate extended beyond the borders of Barotseland, including territories which were Lunda kingdoms. The border to Angola was fixed in a treaty with Portugal in 1891 and again, by King Victor Emmanuel of Italy, in 1905; the border to the Congo Free State also by treaty in 1891."

Note however the errors in Capital being Kalolo instead of Kalomo. And there is reference that the area become a British protectorate, yet only the Northern Rhodesia (when the eastern and western parts where joined), became a protectorate. 

So it is from reading this part that someone thought of drawing that map and gave it to the Litunga. And the Lozi people celebrated that a map of their area has been found. Again I will repeat what I said earlier - there is no map of Barotseland because it was not a country, nor a protectorate that was under any empire. All protectorates and colonies have flags and court of arms, etc for the recognition. The flag of Barotseland is as good as the flag of the Bemba. They are native government flags which had nothing to do with nations.
