Before the transatlantic slave trade reached its height, Africans and Europeans were already connected through trade, diplomacy, and travel. In the late 1400s and 1500s, Portuguese trade with West African kingdoms grew, sub-Saharan Africans lived and worked in Iberian cities like Lisbon and Seville, and Portuguese plantations on Atlantic islands became an early model for the plantation systems later built in the Americas.
Why This Matters for the AP African American Studies Exam
This topic closes Unit 1 by showing that Africa was globally connected long before the transatlantic slave trade. That idea supports the kind of thinking the AP exam rewards: tracing causation, recognizing continuity and change over time, and using sources as evidence. You should be ready to explain why Africans traveled to Europe and Europeans traveled to Africa, and to connect early Portuguese plantation labor on Atlantic islands to the later plantation systems in the Americas. The required image, Chafariz d'El-Rey, is a strong source for practicing visual analysis of African presence and varied roles in Iberian cities.

Key Takeaways
- In the late 1400s, Portuguese trade with West African kingdoms grew for gold, goods, and enslaved people, bypassing the older trans-Saharan trade routes.
- Slave trading was already a feature of some hierarchical West African societies, and African kingdoms used it to build wealth and power.
- This trade increased the European presence in West Africa and the population of sub-Saharan Africans in Iberian port cities like Lisbon and Seville.
- African elites, including ambassadors and rulers' children, traveled to Mediterranean port cities for diplomatic, educational, and religious reasons.
- Free and enslaved Africans in these cities worked in many roles, from domestic labor to boatmen, guards, entertainers, vendors, and knights.
- Portuguese plantations on Cabo Verde and São Tomé became a model for the slave labor economies that later developed in the Americas.
African-European Travel Before the Transatlantic Slave Trade
In the late fifteenth century, trade between West African kingdoms and Portugal grew steadily. Portuguese ships traded for gold, goods, and enslaved people along the West African coast, which let them bypass the older trans-Saharan trade routes that ran across the desert. Slave trading was already a common feature of some hierarchical West African societies, and African kingdoms increased their wealth and power through it.
As these regions became more economically connected, the European presence in West Africa grew, and the population of sub-Saharan Africans in Iberian port cities like Lisbon and Seville rose. This was an exchange that moved in both directions, not just Europeans arriving in Africa.
African Presence in Iberian Cities
African elites, including ambassadors and the children of rulers, traveled to Mediterranean port cities for diplomatic, educational, and religious reasons. These were not only forced migrations. Some Africans came to build alliances, pursue education, or take part in religious life.
In these cities, free and enslaved Africans filled a wide range of roles. They worked as domestic laborers, boatmen, guards, entertainers, vendors, and even knights. That range matters because it shows African people were part of urban European life well before the height of the transatlantic slave trade.
The Rise of Slave-Based Economies
Portuguese Colonization of Atlantic Islands
In the mid-fifteenth century, the Portuguese colonized the Atlantic islands of Cabo Verde and São Tomé. There they established cotton, indigo, and sugar plantations that ran on the labor of enslaved Africans.
These island plantations became a model for the slave labor economies later built in the Americas. They showed European powers a system of large-scale coerced labor that would be copied and expanded across the Atlantic.
African Enslavement in Atlantic Colonies
By 1500, about 50,000 enslaved Africans had been removed from the continent to work on Portuguese-colonized Atlantic islands and in Europe. This early system became the blueprint for the much larger transatlantic slave trade that followed over the next several centuries.
As an application of this model, later Atlantic colonies such as Brazil under Portuguese control and Caribbean colonies under Spanish, French, British, and Dutch control would rely heavily on enslaved African labor. These are examples of how the plantation model spread, not separate required content for this topic.
Required Source: Chafariz d'El-Rey (The King's Fountain), 1570-1580
This painting from the late 1500s gives a rare visual record of African presence in Lisbon, where Africans made up about 20 percent of the city's population in the sixteenth century. It shows the many roles Africans played in an Iberian port city.
Look closely and you can spot specific details that match what this topic teaches:
- João de Sá Panasco, an African Portuguese knight of the Order of Saint James, riding a horse
- Two African noblemen in European attire carrying swords in the right corner
- An African court guard
- Muslim African traders in the upper left
Together, these details show the everyday interchange between African and European societies well before the transatlantic slave trade reached its height.
How to Use This on the AP African American Studies Exam
Using Sources Effectively
When you analyze Chafariz d'El-Rey, do not just describe the scene. Connect details to a claim. For example, the knight João de Sá Panasco and the African noblemen with swords support the point that Africans held varied and even high-status roles in Iberian cities. Always tie a visual detail to an idea about African presence or social roles.
Causation
Be ready to explain cause and effect. Portuguese demand for gold, goods, and enslaved people plus existing West African slave-trading systems led to growing Atlantic trade, more Africans in Iberian cities, and early island plantations. Practice stating the cause and the result in one clear sentence.
Continuity and Change
This topic is strong for continuity and change over time. The Portuguese plantation model on Cabo Verde and São Tomé continued and expanded into the much larger plantation economies of the Americas. Name what stayed the same (coerced African labor on plantations) and what changed (scale and reach).
Common Trap
Do not claim Africa had no contact with the wider world until Europeans arrived. The opposite is true. West African kingdoms, trans-Saharan routes, and African travelers in Mediterranean cities show deep global connections before the transatlantic slave trade.
Common Misconceptions
- "The transatlantic slave trade started all African-European contact." Africans and Europeans were already trading, traveling, and exchanging ideas through Portuguese and Mediterranean connections before that trade peaked.
- "Every African in Europe was enslaved." Both free and enslaved Africans lived in Iberian and Mediterranean cities, working in roles that ranged from laborers to knights, and some elites traveled by choice for diplomacy, education, or religion.
- "Slavery in West Africa was the same as plantation slavery in the Americas." Some West African societies practiced forms of slavery within hierarchical systems, but the Portuguese island plantations helped create the large-scale, race-based plantation slavery that later defined the Americas.
- "The first plantation slave economies appeared in the Americas." Portuguese plantations on Cabo Verde and São Tomé came earlier and served as the model for the systems that spread across the Atlantic.

Frequently Asked Questions
What does Global Africans mean in AP African American Studies?
Global Africans refers to African people and societies participating in wider Atlantic and Mediterranean networks before the transatlantic slave trade reached its height. The topic focuses on trade, diplomacy, African presence in Iberian cities, and early Portuguese plantation labor systems.
Why did Africans travel to Europe before the transatlantic slave trade peaked?
African elites traveled to Mediterranean and Iberian port cities for diplomacy, education, and religious reasons. Free and enslaved Africans also lived and worked in cities such as Lisbon and Seville in roles including domestic laborers, boatmen, guards, entertainers, vendors, and knights.
What does Chafariz d'El-Rey show?
Chafariz d'El-Rey shows the substantial African presence in sixteenth-century Lisbon and the range of roles Africans held there. Details such as João de Sá Panasco, African noblemen, a court guard, and Muslim African traders support claims about African participation in Iberian urban life.
How did Portuguese Atlantic islands shape plantation slavery?
Portuguese plantations on Cabo Verde and São Tomé used enslaved African labor to produce cotton, indigo, and sugar. These island plantations became models for later slave labor-based economies in the Americas.
Were all Africans in Iberian cities enslaved?
No. The CED emphasizes that both free and enslaved Africans lived in Iberian port cities. Some African elites traveled for diplomacy, education, or religion, while others worked in a wide range of urban roles.
How does this topic connect to trans-Saharan trade?
Portuguese coastal trade grew partly by bypassing older trans-Saharan routes. That shift helps explain how Atlantic trade expanded and how West African kingdoms, Portugal, and Iberian cities became more connected.
