Bungu Kongo
Bungu, also called Vungu, was a kingdom in the wooded hills of Mayombe, on the north bank of the Congo River. Tradition at the Kongo court, written down by a Jesuit in 1624, placed the first king of Kongo here before he crossed the river to conquer the lands to the south. King Afonso I named Bungu among his possessions in a letter of 1535. By the 1620s the Jaga, driven out of Kongo, had moved north, allied themselves with Loango and occupied Bungu, close to the coastal kingdoms.
