Papal Decrees and the Authorization of African Enslavement
The history of African enslavement cannot be honestly examined without confronting the role played by European monarchies, commercial interests, colonial law, African intermediaries, and religious authority. Among the most consequential documents in that history are 15th-century papal bulls that gave religious and legal support to Portuguese expansion along the West African coast and helped create a framework in which the enslavement of non-Christian Africans could be justified.
These documents did not by themselves create the transatlantic slave trade. That system developed over centuries through European demand for plantation labour, maritime commerce, military conquest, African wars and raids, and colonial systems of hereditary bondage. The papal bulls of the mid-1400s, however, supplied powerful religious endorsement at a formative stage of European expansion. For that reason, they remain central to any serious discussion of the Church’s historical relationship to slavery, colonialism, and the African diaspora.
On June 18, 1452, Pope Nicholas V issued the papal bull Dum Diversas. Addressed to King Afonso V of Portugal, the document gave the Portuguese crown authority to wage war against Muslims, pagans, and other non-Christian peoples, to seize their lands and possessions, and to reduce them to perpetual servitude. The language reflected the religious and political worldview of medieval Christendom, in which conquest was framed as a mission to expand Christian power and resist Muslim influence.
Granted Portugal authority to invade, capture, vanquish, and subdue non-Christian peoples, and to reduce their persons to perpetual servitude while seizing their kingdoms and possessions. Addressed to King Afonso V and understood as ecclesiastical license for Portuguese maritime expansion along the African coast.
Three years later, on January 8, 1455, Pope Nicholas V issued Romanus Pontifex. This bull reaffirmed and expanded Portuguese rights along the African coast, recognized Portuguese claims to exploration, trade, and conquest, and strengthened Portugal’s monopoly over emerging routes and territories. Most significantly, it gave further religious sanction to the enslavement of non-Christian Africans encountered through Portuguese expansion.
Reaffirmed and expanded the rights granted in Dum Diversas. Established a Portuguese trading monopoly on the African coast and explicitly authorized the enslavement of non-Christian Africans during exploration and conquest. Along with Dum Diversas, became central to the body of papal and legal reasoning later associated with the Doctrine of Discovery.
These bulls became part of a broader body of papal and European legal reasoning later associated with what is commonly called the Doctrine of Discovery, used by European powers to claim lands, dominate Indigenous peoples, and justify systems of conquest in Africa and the Americas. In 2023, the Vatican formally repudiated concepts associated with that doctrine and recognized that earlier papal documents did not adequately reflect the equal dignity and rights of Indigenous and African peoples.
The power of these documents was not merely theological. In the 15th century, papal authority carried enormous political weight across Europe. When the papacy granted permission to conquer, subdue, and enslave non-Christian peoples, it strengthened the hand of European monarchs already seeking wealth, territory, and control over trade routes.
Portugal’s early ventures along the West African coast were driven by multiple goals: access to gold, control of maritime commerce, competition with Muslim powers, and eventually the trafficking of human beings. The Church’s authorization did not replace those economic motives. It helped sanctify them, placing conquest and enslavement inside a religious framework that portrayed European expansion as a Christian enterprise.
Between the 16th and 19th centuries, an estimated 12.5 million Africans were forced onto slave ships bound for the Americas. Approximately 10.7 million survived the Middle Passage. The rest died at sea through disease, starvation, violence, suicide, and the inhuman conditions aboard slave ships. These figures are drawn from the Transatlantic Slave Trade Database, the most comprehensive scholarly record of the trade.
Those who survived were sold into systems of chattel slavery across the Caribbean, Brazil, North America, and other parts of the Americas. Enslaved Africans and their descendants were treated as property, denied legal personhood, separated from family, subjected to sexual violence, and forced to labour in plantation economies built on sugar, tobacco, cotton, rice, coffee, and mining. Children inherited the enslaved status of their mothers. Human beings were bought, sold, mortgaged, punished, branded, and worked to death. The wealth extracted from their bodies helped build European empires and colonial economies, while African societies were destabilized by raids, warfare, and depopulation.
Catholic teaching on slavery developed unevenly over time. In 1537, Pope Paul III’s bull Sublimis Deus affirmed the humanity and natural rights of Indigenous peoples of the Americas and declared that they should not be deprived of liberty or property. Enforcement was inconsistent. In 1839, Pope Gregory XVI’s In Supremo Apostolatus condemned the slave trade and warned Catholics against participating in it. Later papal statements continued to move further from the earlier permissions granted to European crowns.
The most significant recent development came on May 25, 2026, when Pope Leo XIV apologised in his first encyclical, Magnifica Humanitas, for the Holy See’s own institutional role in legitimising slavery and for failing to condemn it with sufficient clarity for centuries. Previous popes had condemned slavery in general terms or addressed individual Christians’ participation. Leo XIV was the first to direct an apology at the papacy itself as an institution.
In his encyclical, Leo acknowledged that the Apostolic See had intervened in the early modern period “to regulate and legitimize forms of subjugation, and, in certain cases, including the enslavement of ‘infidels.'” He wrote that while it was not possible to judge those decisions solely by today’s moral standards, “neither can we deny or diminish the delay with which both society and the Church came to denounce the scourge of slavery.” He described the Vatican’s record as “a wound in Christian memory” and stated: “For this, in the name of the Church, I sincerely ask for pardon.”
Leo XIV is the first U.S.-born pope. According to genealogical research published by Henry Louis Gates Jr., his family history includes both enslaved people and slaveholders.
The Catholic Church was not the only institution responsible for the transatlantic slave trade. Portuguese, Spanish, British, French, Dutch, Danish, and other European powers built colonial economies dependent on enslaved African labour. European merchants, ship owners, investors, insurers, banks, and plantation owners profited from the buying and selling of human beings. Colonial legislatures wrote laws that converted African identity into inherited enslavement across generations.
African kingdoms, traders, and military elites also participated in the capture and sale of captives through warfare, raids, punishment, debt, and political rivalry. Their participation does not reduce European responsibility, but it forms part of the full historical record. Some Catholic orders and institutions owned enslaved people or benefited from plantation economies. Others opposed those abuses, defended the humanity of enslaved and Indigenous peoples, or supported abolition. The record contains complicity, contradiction, resistance, silence, and delayed repentance.
For the African diaspora, including the people of St. Vincent and the Grenadines, this history is not distant. The Caribbean was one of the central theatres of plantation slavery. Sugar economies transformed islands into sites of forced labour, racial hierarchy, and colonial extraction. African people carried across the Atlantic brought languages, spiritual systems, agricultural knowledge, music, resistance traditions, and cultural memory that continue to shape Caribbean identity.
In St. Vincent and the Grenadines, the history is especially connected to the Garifuna, known historically as the Black Caribs. The Garifuna trace their ancestry to Africans who reached St. Vincent through shipwreck, escape, and resistance, and who integrated with Indigenous Kalinago communities. Their resistance to British colonial power became one of the defining chapters in Vincentian history. After their defeat, many were exiled from St. Vincent in 1797 and transported to Central America, where Garifuna communities continue to preserve their language, identity, and ancestral connection to Yurumein, their name for St. Vincent.
This legacy is directly relevant to modern debates over reparations, historical education, land, sovereignty, and restorative justice. CARICOM’s reparations movement is rooted in the argument that slavery and colonialism were not accidental tragedies but organized systems of extraction that enriched Europe while damaging African and Indigenous peoples across generations.
The 1452 and 1455 papal bulls represent a serious chapter of institutional complicity. They show that religious authority was used to legitimize conquest, dispossession, and the enslavement of Africans by a European power. The full history includes many actors and many layers of responsibility, but the role of papal authority cannot be dismissed or minimized.
A truthful account must hold several realities together: European empires built and profited from slavery; African intermediaries participated in the trade; colonial laws converted human beings into property; religious authorities at key moments gave moral and legal support to systems of conquest and enslavement. Later Church condemnations and apologies are important, but they must be understood against the centuries of suffering that preceded them.
For the African diaspora, truth-telling is not about hatred. It is about historical clarity, naming the systems that produced dispossession, racial hierarchy, and inherited trauma, and demanding that memory be treated as part of justice.
Vincypowa News maintains that serious public discourse must be grounded in evidence, primary documents, and historical context. The story of African enslavement is too grave to be reduced to slogans, and too important to be softened for comfort. Only by facing the record honestly can societies move toward meaningful reconciliation, reparations, and justice.
