Step-by-step explanation:
The Congo-Angola region in Africa was significant during the eighteenth century primarily because of its role in the transatlantic slave trade. The area was a major source of slaves for the Americas and the European colonial powers, especially Portugal, Britain, and France. This had enormous implications on the region's demographic, social, and economic landscapes.
In this period, the slave trade took center stage, and millions of Africans were forcibly taken from this region, leading to a dramatic population decline. The societies of the Congo-Angola region were distorted and disrupted, experiencing significant societal changes. Regional economies also experienced shifts as trade networks grew around the lucrative slave trade.
In addition, the 18th century saw the rise of powerful kingdoms such as the Kingdom of Kongo and Ndongo, which participated and profited in this trade as they negotiated with European traders.
