Portugal appears in the account not simply as a distant European country, but as the power whose arrival reshaped Angola through conquest, slave trading, and colonial rule. Its history there begins with exploration in the late fifteenth century, hardens into centuries of warfare and extraction, and reaches a formal turning point in 1975, when Portugal joined Angola’s liberation movements in an agreement granting the country independence.

A European power in an African setting

The scale of Angola makes the contrast with Portugal striking. Angola covers 1,246,700 square kilometres, about fourteen times Portugal’s area. Its long, poorly demarcated land borders run through largely uninhabited bush, a geography that the account identifies as a serious defensive problem for a country surrounded by unfriendly neighbours. Portugal, by contrast, enters the narrative as the overseas power governing a territory far larger than itself.

The book traces Portuguese expansion to 1482, when the captain Diogo Cão arrived at the mouth of the Congo River. The Kingdom of Kongo flourished in the region, with its capital at Mbanza Congo, later known in Portuguese times as São Salvador. The arrival marked the beginning of Portuguese expansion in this part of Africa, but not the immediate conquest of Angola. That followed roughly ninety years later: in 1573, Paulo Dias de Novais established a settlement named Luanda and led soldiers down the Cuanza River. The sequence distinguishes contact and expansion from the later establishment of a colonial foothold.

Conquest, war, and the slave trade

The account links Portugal’s presence in Angola above all to the export of enslaved people. European plantation demand for sugar and cotton created a demand for a large, cheap workforce; Angola became a principal source. Historians estimate that three to four million people were shipped from territories within the borders of present-day Angola. The scale is set against Portugal’s own historical population: when it was a world power with possessions across several continents, the country had barely one million inhabitants.

The slave trade was not separate from military conquest. To seize people for export, the Portuguese fought repeated wars across Angola. The historical account describes warfare as nearly continuous over the period from 1579 to 1921: in 350 years, Portuguese archival documents record scarcely five years in which Portugal did not wage war somewhere in the territory. This history gives military expansion a particular function in the narrative: it was a means of securing human beings for export, not merely a succession of isolated campaigns.

The effects of that extraction extended beyond Angola. By the first half of the nineteenth century, slave exports accounted for more than 90 percent of the total value of Angola’s exports. Descendants of Angolan slaves formed a significant part of the populations of Brazil, the Dominican Republic, and Cuba. The account also connects this history to later political ties: despite their fundamental political differences, Brazil was the first state to recognize the People’s Republic of Angola, while Cuba gave substantial assistance to the liberation forces. The Atlantic is thus described as a link between African and Latin American histories as well as a route of forced displacement.

The colony as a place of deportation

Portugal’s colonial relationship with Angola also carried a social meaning within Portugal itself. For centuries, the country directed what the account calls its best elements to Brazil and its worst to Angola. Angola served as a penal colony and a destination for criminals, outcasts, and people at the edges of Portuguese society. In old Lisbon, it was known as the country of the deported and expelled—a place imagined as the end of the road for those Portugal cast out.

The account connects this history of deportation to Angola’s colonial condition, arguing that the low quality of its colonists helped make it one of Africa’s most backward countries. That judgment sits alongside the much larger record of enslavement and war: Portugal’s rule shaped the colony both by extracting people and wealth and by sending unwanted people from the metropole to its territory. In the early twentieth century, the damage and vulnerability of Portuguese rule were underscored by secret negotiations in which England and Germany considered taking the colony from Portugal and dividing it between them. German forces occupied southern Angola until 1915, and Afrikaners occupied the southern province of Huíla until 1928.

From Portuguese rule to the independence agreement

The armed struggle for Angolan liberation gathered significant force only in the middle of the twentieth century. A revolution in Portugal on 25 April 1974 preceded the final negotiations over the colony’s future. On 25 January 1975, the MPLA, FNLA, UNITA, and the Portuguese government signed the Alvor Agreement in Portugal. It created a provisional coalition government in Angola and set 11 November 1975 as the date for independence.

The agreement placed Portugal at the formal end of the colonial arrangement, but it did not ensure a lasting coalition: the provisional government took effect in Luanda on 30 January, and five months later the FNLA and UNITA resigned. On 11 November, Angola became the People’s Republic of Angola, with Agostinho Neto as its first president. The account’s arc therefore moves from the Portuguese arrival at the Congo River, through a colonial order maintained by warfare and slave exports, to an independence settlement made on Portuguese soil—and to a new Angolan state whose political future would no longer be defined by Portuguese rule.
