Kakongo
Kakongo was a former small kingdom located on the Atlantic coast of Central Africa, in the modern-day Republic of Congo and Cabinda, Angola. It along with its southern neighbor, Ngoyo, and Loango, its neighbor on the north were important political commercial centers during the seventeenth through nineteenth 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 Kongo for a part of its history. Early history. The earliest history of Kakongo is unknown, and oral traditions collected in the region in the  nineteenth and twentieth centuries do not do much to elucidate the earliest history of the country. In its present state, archaeology can only attest that the region was already in the Iron Age by the fifth century BC, and that complex societies were emerging in the general vicinity by the early centuries CE. The kingdom is first mentioned in the titles of the King of Kongo Afonso I in 1535, in which he notes that he was king over this region, as well as a number of others located along the north bank of the Congo River. This title has  led historians to believe that Kakongo was once part of a federation of states that included Kongo and that may have formed as early as the late fourteenth century. Kakongo was, however, an independent state for all intents and purposes from the sixteenth century onward. Portuguese merchants, interested in the trade in copper, ivory, and slaves began to establish factories in Kakongo in the 1620s and Dutch and English merchants also visited the kingdom during the seventeenth century. Its capital was called Kinguele, and was an inland town. Commercial center. Kakongo became a very important commercial center in the eighteenth  century, regularly visited by ships from England, France, the Netherlands, and Portugal. Its port of Cabinda was a major hub that laid in a protected bay. Slaves dominated the exports of the country, though most were simply transhipped from areas further south, mostly from the Kingdom of Kongo and the eastern provinces of Angola (such as Matamba). Important goods that were also traded, were gunpowder, guns, knives, cotton cloths, glass beads, copper and iron bars. In 1775, French missionaries sought to convert the kingdom, along with its neighbors, to Christianity, hoping to reap the fruit of its long association with  the neighboring, Christian, Kingdom of Kongo. The mission was largely unsuccessful, but did make contact with a community of Christians from Kongo's province of Soyo living at the town of Manguenzo in the interior. The mission was ultimately abandoned, however.
