The Kingdom of Kongo was a powerful state located in Central Africa, primarily in what is now northern Angola and the western part of the Democratic Republic of the Congo. It emerged in the late 14th century and became known for its complex political structure, trade networks, and cultural achievements. The kingdom was ruled by a king, known as the Manikongo, and had a well-organized system of provinces. The Kingdom of Kongo established significant trade relations with European powers, particularly the Portuguese, in the late 15th century. This interaction led to the introduction of Christianity and European goods, but also to the devastating impact of the transatlantic slave trade. Despite its decline in the 18th century, the legacy of the Kingdom of Kongo continues to influence the region's culture and history.
