[1] Kongolo Mwamba was trying to extend his kingdom by conquering the neighbouring Songye chiefdoms.
He met a prince of the Kunda people on behalf of Ilunga Mbidi through its sisters who had met at the lake; Mbidi, being a late military strategist, helped Kongolo expand his Kingdom.
With the help of his wives, Ilunga Mbidi absconded by leaving women and children while returning to Kunda.
At the last attempt, Kalala Ilunga decided to end it, and defeated and killed Kongolo after a victory on the battlefield.
After severing the head and genitals of Kongolo, he was proclaimed Emperor, or Mulopwe.
