Kakongo was a small kingdom located on the Atlantic coast of Central Africa, in the modern-day Republic of the Congo and Cabinda Province, Angola. In the 13th century, it formed part of a confederation led by Vungu. Along with its neighboring kingdoms of Ngoyo and Loango, Kakongo became an important political commercial center during the 17th through 19th centuries. The people speak a dialect of the Kikongo language and thus may be considered a part of the Bakongo ethnicity. Kakongo was a vassal of the Kingdom of Kongo for a part of its history.
