Christians and Islam were involved in a religious war. Henry the Navigator, along with Portugal as a whole, wanted to halt the Islamization of Africa by approaching them from the rear and stopping them there.

Another huge reason for the colonization of Africa by Portugal was for resources: Sugar, minerals, diamonds, and other agriculture. There is also an aspect of growing colonies and establishing trade as not to be beaten by other colonizing powers.

Portuguese authorities militarized borders in resource-rich areas to protect economic assets like diamond fields (Angola) and plantations (Mozambique). Borders were fortified especially after 1960 to suppress independence movements.

While the numbers are ticking up over the years, there is a clear and dramatic drop between the numbers of students enrolled in adapted teaching and those in high school (240,813 to 231).

There are many more African students enrolled in Technical or Seminary education, rather than receiving an Academic education (10-40 students).

• What are the priorities of those controlling what students are enrolled in?

• Putting an emphasis on Manual Labor and Religion (which was used as a means to control).

• Limiting job opportunities?

ACTIVITY: Read Benin's Use of Religion Against Portuguese Colonization.

Women had an important role in spreading Portugal's religion. Family and Religion were seen as interdependent. After seeing their influence on society, the focus of the settlers was directed towards converting African women so that they could help solidify Christianity's integration into society.

"The African woman must be made a dyanmic force whose interests center in the home and family…the effort for integration must be directed…toward attracting native women to our culture.”

The Portuguese had a "self-acknowledged Christian paternalism to the African." They hoped to civilize the territories they touched by integrating their religion, and eventually their colonial policies and strategies on them.

• Angola’s diamond wealth, especially under the Companhia de Diamantes de Angola (Diamang), became central to Portugal’s colonial economy. 

• Diamang, backed by the state and foreign capital, monopolized mining zones in northeastern Angola. 

• Indigenous populations were forcibly resettled and subjected to harsh labor under the indigenato system. 

• The region’s borders were militarized to protect mining zones from internal resistance and foreign interest.
  

Mozambique – Agriculture and Mineral Routes (Late 19th–20th Century):

• Mozambique’s fertile Zambezi Valley and inland mineral transport corridors were exploited through plantation systems managed by settler and corporate interests. 

• Cash crops like cotton and sugar dominated, driven by coerced labor through villagization. 

• Colonial borders were adjusted to secure ports (Lourenço Marques, Beira) and railways for export flow, emphasizing Mozambique’s role as a resource conduit to Indian Ocean trade.
  

São Tomé and Príncipe – Sugar and Cocoa (15th–20th Century):

•  São Tomé became one of Africa’s largest sugar producers in the 16th century using enslaved African labor.

•  In the 19th and 20th centuries, it shifted to cocoa, with Portuguese plantations relying on contract laborers, often coerced from Angola and Cape Verde. 

• The islands were isolated from mainland African politics but functioned as key export hubs, maintaining distinct colonial boundaries geared toward economic mono-production.
  

Guinea-Bissau – Cashew, Groundnuts, and Bauxite (20th Century):

•  Though considered peripheral, Guinea-Bissau held agricultural value (cashew, groundnuts) and potential mineral resources (bauxite). 

• Land was expropriated from indigenous peoples, and forced labor systems supported plantation agriculture. 

• Colonial borders here were more arbitrary, shaped by local resistance and weak infrastructural investment, making them fragile and often shifting during military campaigns.
  

Cape Verde – Limited Resources, Strategic Role (15th–20th Century):

•  Despite scarce arable land and resources, Cape Verde was essential as a transatlantic resupply and labor-sourcing hub. 

• The islands were a launching point for slave routes and later used as labor reserves for plantations in São Tomé and Angola.

• Its fixed borders reflected more maritime interests than resource abundance, showing Portugal’s naval and logistical priorities in Atlantic Africa.

Taxation: The Portuguese colonial administration implemented taxes, such as the hut tax (introduced in 1907) and later the poll tax (1919), to compel African populations into the monetary economy and wage labor. These taxes forced individuals to seek employment, often under exploitative conditions, to meet tax obligations. 

Forced Labor Systems: In regions where cash tax payments were unfeasible due to low monetization, the colonial authorities resorted to forced labor as a means of tax payment. This practice was prevalent in less developed areas, where individuals unable to pay taxes in cash were compelled to work on plantations or infrastructure projects for minimal or no wages. 

Legal Framework for Coerced Labor: The 1899 Indigenous Work Regulation codified various forms of forced labor, including "compelled," "corrective," "public interest," and "hired" labor. These regulations mandated that those not voluntarily engaging in work could be compelled by authorities, effectively institutionalizing forced labor under the guise of moral and social obligations. 

Regional Variations in Taxation and Labor: The implementation of taxation and labor control varied across Portuguese colonies:​

Ex:

• Southern Mozambique: Characterized by labor migration to South African mines, with the colonial state profiting from migration taxes and deferred wages

• Central Mozambique: Dominated by concession companies that collected taxes and utilized forced labor for plantation agriculture.​

• Northern Mozambique: A peasant-based economy with late colonial presence, where forced cotton cultivation was imposed, diverting labor from food production.

• If someone does not live in one of these areas where it is "justified" to have a school, education can be difficult to acquire even just based on location.

“There is also considerable political will within the current government, although the [low] level of attention devoted to the bilingual program (e.g. lack of resources in African languages) may lead one to conclude otherwise.” (ibid., p. 68)”

• Pilot Bilingual Program proposed in 2017- very little resources/money/attention were given to it, even though there were many Africans who expressed a large amount of interest in it.

  • "“At the end of the experiment, ‘two school directors reported that families in PEBIMO communities had taken in children from relatives or friends in anticipation of their being able to attend [future] bilingual classrooms'."

• However this creates a loop: in order to obtain an education, you must have the resources as well as knowledge of Portuguese. However, most people needed schooling to learn Portuguese and open up opportunities.

"It almost seems that the system itself is a discouraging force, and one may conclude that education for the African does not occupy a notable place in Portugal’s policies of assimilation."

"Education for the African in the Portuguese colonies is progressively selective."

If you were to look at this from the colonizers' perspective, what could be some benefits of the locations they colonized?

Does capitalism play a role? If yes, how?

Do you think that control and opportunity for resources were the strongest motivators for Portugal's colonization of these territories? Why or why not?

Do you think the actions of other colonial powers at the time affected Portugal's actions in colonizing certain areas of the continent?

Cape Verde was uninhabited when first discovered by the Portuguese. In 1582 had 1608 whites, 400 freed slaves, 13,000 slaves.

Thinking/Reflection Question: What trend do you notice? What might the social dynamics be in a racially imbalanced society?

"In a system where 'Portugalisation' and 'nationalization' meant that the key to economic betterment implied a process of 'detribalisation' and 'assimilation' to the Portuguese way of life, those who were left aside were completely marginalized both culturally and economically. And since the assimilation policy of the Portuguese colonial state was largely a failure... those left aside were in fact the overwhelming majority"
