The Lagos Slave Market

1444

On 8 August 1444, a fleet of six caravels under the command of Lancerote de Freitas arrived at Lagos harbour carrying 235 captive Africans seized from the coast of what is now Mauritania and Senegal. The captives were brought ashore and divided into lots in a field outside the town walls, in what is generally regarded as the first large-scale slave auction in Europe. The chronicler Gomes Eanes de Zurara, writing under royal patronage, left a detailed and at times disturbed account of the scene, describing families being separated and the distress of the captives as they were parcelled out among Portuguese buyers.

This event at Lagos marked the beginning of the European transatlantic slave trade, a commerce that would grow over the following four centuries into one of the largest forced migrations in human history. While slavery had existed in various forms across the Mediterranean world for millennia, the Portuguese innovation was to establish a systematic, state-sanctioned trade in enslaved Africans, driven by commercial motives and underpinned by papal bulls that granted Portugal the right to subjugate and enslave non-Christian peoples.

Prince Henry the Navigator held the royal monopoly on trade with West Africa and was the direct beneficiary of these early slave-trading voyages. The profits from the sale of enslaved people helped finance further voyages of exploration, creating a grim economic cycle in which human suffering funded geographical discovery. The church offered theological justifications, arguing that enslavement brought the captives into contact with Christianity and thus served their spiritual welfare, a rationalisation that strikes modern readers as deeply cynical.

Lagos remained a significant slave trading centre throughout the 15th century, though Lisbon gradually superseded it as the volume of the trade increased and the administrative centre of the empire shifted northward. By the early 16th century, Lisbon had a substantial enslaved population, estimated at around ten per cent of the city's inhabitants. The impact on West African societies was devastating, though the full scale of the destruction would not become apparent until the trade reached its peak in the 17th and 18th centuries under British, French, Dutch and Portuguese operation.

The building in Lagos traditionally identified as the slave market, the Mercado de Escravos, stands near the Praca do Infante on the town's waterfront. The structure visible today is a 17th-century customs house rather than the original 15th-century market, but it has been converted into a museum that documents the history of the slave trade in the Algarve and its wider context. The museum, opened in 2016, presents the archaeological evidence uncovered during building work, including the remains of enslaved Africans found in a nearby waste deposit, subjected to isotopic analysis that confirmed their West African origins.

The Lagos slave market is a site that demands honest reckoning. It reminds visitors that the Age of Discovery, for all its navigational brilliance, was built in part on the systematic exploitation of African peoples. The Algarve's role as the birthplace of the European slave trade is an uncomfortable but essential element of the region's history, one that the museum at Lagos now presents with appropriate gravity and scholarly rigour.

Impact

Lagos's role as the origin point of the European slave trade remains a defining and sobering element of the Algarve's and Portugal's historical legacy.
