Kingdom of Kongo in the Seventeenth Century

Timeline

1. 1641–1648Mbanza Kongo and Luanda · AngolaAfter Garcia II ascended the throne (1641), he immediately formed an anti-Portuguese alliance with the Dutch West India Company, and Dutch forces used this to capture the port of Luanda in 1641. However, in 1648 Portugal dispatched troops from Brazil to retake Luanda, the Dutch were expelled from Angola, Kongo lost its external strategic counterweight against Portugal, and was forced to rely once more on diplomatic mediation.
2. 1651–1660Mbanza Kongo · AngolaBetween 1651 and 1660, Garcia II submitted diplomatic letters to Pope Innocent X and Alexander VII through Franciscan and Capuchin missionaries, seeking Roman Curia intervention against Portugal's slave raiding and political oppression. Although the results were minimal, these diplomatic activities demonstrated the Kongo elite's profound understanding of the European international system and recorded an early expression of African state sovereignty consciousness.
3. 1651–1660Throughout the Kingdom of Kongo · Central AfricaThe Atlantic slave trade caused sustained demographic and political losses to the Kingdom of Kongo: provincial nobles (Mani) waged wars against one another to obtain slaves, and prisoners of war were sold to Portuguese merchants. Between 1651 and 1660, internal factional conflicts intensified, central authority waned, and provincial autonomy grew. This structural weakening laid the historical roots for Portugal's decisive military victory at the Battle of Mbwila in 1665 and the kingdom's subsequent descent into prolonged civil war and fragmentation.
