The Kingdom of Kongo (Kongo: Kongo dya Ntotila or Wene wa Kongo or Portuguese: Reino do Congo) was an African kingdom located in west central Africa in what is now northern Angola, Cabinda, the Republic of the Congo, the western portion of the Democratic Republic of the Congo, as well as the southernmost part of Gabon. At its greatest extent, it reached from the Atlantic Ocean in the west to the Kwango River in the east, and from the Congo River in the north to the Kwanza River in the south. The kingdom consisted of several core provinces ruled by the Manikongo, the Portuguese version of the Kongo title 'Mwene Kongo', meaning lord or ruler of the Kongo kingdom, but its sphere of influence extended to neighbouring kingdoms, such as Ngoyo, Kakongo, Ndongo and Matamba.
