The Congo River is presented as the setting for an early encounter between Portuguese expansion and an established African kingdom. Its significance in the account is historical: the arrival at its mouth in 1482 marks a starting point in the chronology that leads, decades later, to the Portuguese settlement of Luanda and the conquest of Angolan territories.

The River and the Kingdom of Kongo

In 1482, the Portuguese captain Diogo Cão arrived at the mouth of the Congo River. The account emphasizes that the Kingdom of Kongo flourished in the region at the time, with its capital at Mbanza Congo, called São Salvador during Portuguese rule. The river thus appears not as an empty frontier but as the setting of a powerful African kingdom encountered by Portuguese expansion.

From Contact to Colonial Expansion

The book treats Diogo Cão’s arrival as the beginning of Portuguese expansion in this part of Africa, while distinguishing it from the later conquest of Angolan territories. That conquest began about ninety years afterward: in 1573, Paulo Dias de Novais established a settlement named Luanda and set out with soldiers down the Cuanza River. The sequence places the Congo River within a wider chronology of colonial advance, while identifying Luanda and the Cuanza as the setting for the subsequent campaign.

The account also places the 1482 arrival within a global history of slavery. It notes that Columbus reached the American continent ten years later, and links the growth of plantation labor demand in the Americas to the beginning of the slave trade. Angola became a major source: historians, the book reports, estimate that three to four million enslaved people were shipped from territories within its present borders. This is presented as historical context following the river encounter, not as a claim that the river itself caused or organized the trade.

The Region in 1975

The historical account returns to the region in 1975 through São Salvador, described as a small provincial town and the capital of Angola’s Zaire province. The town’s political significance is tied to Holden Roberto and nearly the entire leadership of the FNLA, who came from there. This later reference gives the Congo River’s historical setting a connection to the contemporary political geography of the book: a region associated with an early Portuguese arrival also figures in the origins of a major Angolan movement.
