Boma
The Boma people inhabit the country between the Congo and the waterways of Lake Mai-Ndombe. Their kingdom, also called Ibar or Giribuma, grew around the lake and the rivers that connect it with the Kasai. Boma traditions recall movements into this region under a succession of leaders, while their varied communities trace connections to the Tio kingdom farther west. The rivers and lake joined the Boma to neighbouring peoples in a network of exchange extending through the Congo basin.
