The following information comes from Marvin Miracle’s article on ‘Migration of the Northern Rhodesian Senga’, published in 1963.
It would seem that the Senga, Bisa and Bemba all left the Lunda empire during the reign of a particularly bad king, Mwata Yamvo. The Lunda king had his palace at a place called Uluwa.
Family clans under Lunda government were given one particular task to carry out. The Bemba were part of the Nandu or crocodile clan whose duty was to sweep the royal village. The Bisa (Ngona or mushroom) clan were tasked with preparing millet for the royal brew. It is not known what duties were allocated to the Senga clan. According to the opinion of Marvin Miracle the Senga left the Lunda Empire first. Their planning to leave took several years but eventually, one night, the men fled and travelled east. During their migration they stopped for a long time and it was during this time that the Bemba and Bisa clans also fled the Lunda Empire. When the Senga continued their migration east, they came to meet up with the Bisa who had settled there.
