  The geographical area now known as the Democratic Republic of the Congo was populated as early as 90,000 years ago, as shown by the 1988 discovery of the Semliki harpoon at Katanda, one of the oldest barbed harpoons ever found, believed to have been used to catch giant river catfish.
  
  Bantu peoples reached Central Africa at some point during the first millennium BC, then gradually started to expand southward. Their propagation was accelerated by the adoption of pastoralism and of Iron Age techniques. The people living in the south and southwest were foraging groups, whose technology involved only minimal use of metal technologies. The development of metal tools during this time period revolutionized agriculture. This led to the displacement of the African pygmies. Following the Bantu migrations, a period of state and class formation began circa 700 with three centres in the modern-day territory; one to the west around Pool Malebo, one east around Lake Mai-Ndombe, and a third even further east and south around the Upemba Depression.: 17–18
  
  By the 13th century, there were three main confederations of states in the western Congo Basin around Pool Malebo. In the east were the Seven Kingdoms of Kongo dia Nlaza, considered to be the oldest and most powerful, which likely included Nsundi, Mbata, Mpangu, and possibly Kundi and Okanga. South of these was Mpemba which stretched from modern-day Angola to the Congo River. It included various kingdoms such as Mpemba Kasi and Vunda. To its west across the Congo River was a confederation of three small states; Vungu (its leader), Kakongo, and Ngoyo.: 24–25
  
  The Kingdom of Kongo was founded in the 14th century and dominated the western region. The empire of Mwene Muji was founded around Lake Mai-Ndombe. From the Upemba Depression the Luba Empire and Lunda Empire emerged in the 15th and 17th centuries respectfully dominated the eastern region.
