The tradition began with speakers of Proto-Bantu in the Grassfields and the forest edge of what is now western Cameroon and eastern Nigeria, where the closest relatives of the Bantu languages are still spoken. From there, beginning roughly 5,000 to 4,000 years ago, their descendants spread south and east over many centuries until Bantu languages covered most of Africa south of the equator.
The universe is told here through specific peoples whose stories and rites are well recorded: the Bakongo of the lower Congo River in the DR Congo, Republic of Congo and Angola; the Baluba of the Upemba Depression and Katanga; the Banyanga of eastern DR Congo, keepers of the Mwindo epic; the Mongo and Nkundo of the central Congo basin; the Bakuba of the Kasai; the Bemba of northern Zambia; the Lozi of the upper Zambezi; the Shona of Zimbabwe; and the AmaZulu and AmaXhosa of South Africa.
The spread was not a single march. It was centuries of village fission, farming and fishing communities moving along rivers and forest edges, meeting and mixing with hunter-gatherers and other farmers. Iron working joined the movement later and spread through it.
Cultural Values
1. Ubuntu, botho, hunhu: personhood is made through relationship. A person becomes fully human by how they treat others, and a selfish person may be said to have no ubuntu.
2. Continuity with the ancestors. The living and the dead are one community. The ancestors are owed respect, offerings and good conduct, and they protect the lineage in return.
3. Balance and health of the whole. Illness, drought and misfortune are signs that relations among people, ancestors and spirits have gone wrong, and they are mended collectively.
4. Respect for elders and for rightful authority, within limits. Chiefs and kings rule by consent and counsel; stories often punish rulers who become cruel or greedy.
5. Fertility and continuity of the lineage, linking marriage, children, land and the furnace.
Priority runs from collective to individual and from ancestors to the present. These values produce story logic that can surprise Western readers: the hero's triumph may be a problem if it threatens the community; a story may end with a lesson in humility rather than a reward; a successful individual may be suspected of using harmful power if wealth is not shared.
