Barotseland, as its recent past becomes revealed to us from the second half of the sixteenth century, seems to have had as a dominant people the _Aluyi_; and as other tribes of importance the _Tonga_ group (Ila-Tonga-Subia) in the south and south-east, the _Luena_ or _Lubale_, _Mbunda_, and _Lujazi_ tribes of northern Barotseland and the adjoining parts of Angola, the _Nkoya-Mbwela_ peoples of eastern Barotseland; and a section of the southern _Luba_ folk. Sporadically there has also occurred a strong invasion of the _Lunda_ people (Ma-bunda) into the northernmost basin of the Zambezi, but it is doubtful whether these immigrants penetrate into the political limits of Barotseland. Similarly a section of another vigorous South Congo people has colonized the Northern Zambezi basin; the Luba, who are known in North-Eastern Barotseland as the _Kahonde_ or _Kaondi_. Then again the enterprising, uppish, cheeky _Va-chokwe_ or “Ba-joko” traders—once the slave-traders of South Congoland and Eastern Angola—circulate through Northern Barotseland and add yet another type of Bantu language to its markets and meetings. The dominant language at Court and in trade to-day is an almost artificially-manufactured tongue which had come into existence during the last fifty years—_Si-kololo_. This will be found illustrated in its most modern form in the first volume of my _Comparative Study of the Bantu and Semi-Bantu Languages_ (Oxford, 1919). My information has been mainly derived from the _Sikololo Grammar and Vocabulary_ published in London by Dr. Stanley Colyer in 1917, and from a _Sikololo Phrase-book_ produced two years’ earlier by Mr. Stirke, the author of this book, in conjunction with a very noteworthy colleague, Mr. A. W. Thomas, formerly master of the Barotse National School. _Sikololo_ which has gradually displaced and superceded the Sechuana or Sesuto language of the original Bechwana invaders of a hundred years ago, is a far easier language to speak and pronounce than the difficult and highly peculiar idiom of Central South Africa. To philologists, Sechuana and its later southern specialization, Sesuto, are intensely interesting. Sechuana entered South Africa at as ancient a date as any other Bantu tongue—say sixteen or seventeen hundred years ago, coming thither from South-East Africa. But since then it has become highly specialized. The most specialized form of it was the southernmost, Sesuto, scarcely distinguishable a hundred or more years ago from the Sepedi of the Western Transvaal.
