Lusongui
Lusongui lies in the high country near the Luvua, between Lake Mweru and the Lualaba. The Hemba inhabited the western part of the region bounded by the Luvua, Lukuga and Lualaba rivers. Before 1810, a son of the Luba ruler Ilunga Sungu established the client kingdom of Kyombo Mkubwa in the country between the Luvua and Lukuga.
